Marital status and survival in patients with cancer

Underserved head-and-neck and lung cancer patient characteristics are associated with caregiver participation in a clinical trial

Background

Patient-caregiver relationships affect cancer outcomes, yet factors related to joint enrollment in cancer research trials are unclear. This work examined associations between cancer patients' sociodemographic and health factors and their caregivers' trial participation.

Methods

Baseline data were drawn from a parent trial testing psychosocial interventions delivered to medically underserved head-and-neck cancer (HNC) and lung cancer (LC) patients (N = 274) and caregivers (N = 210). Logistic regression evaluated whether patient characteristics were associated with participating alone versus with a caregiver(s) and type of caregiver.

Results

Many patients (65.0%) had a caregiver in the study, which was more common for married (OR = 2.05, p < .01) and retired patients (OR = 1.95, p < .05). Patients who indicated Hispanic (OR = 2.31, p < .05), Medicaid insurance (OR = 4.12, p < .001), monthly income <$4000 (OR = 3.04, p < .01), and smoked (OR = 2.87, p < .01) were more likely to enroll with a non-spouse/partner caregiver versus a spouse/partner. Participation was unrelated to distress.

Conclusions

Patient characteristics highlight caregiver relationships, informing trial design and recruitment for medically underserved cancer populations. Psychosocial interventions targeting underserved patients and their informal caregivers, those most in need of intervention support, should consider the inclusion of non-spousal cancer caregivers. Understanding how patient factors may be associated with caregiver involvement informs recruitment strategies and increases the utility of psychosocial interventions.

Gender differences in tumor characteristics, treatment and survival of colorectal cancer: A population-based study

BACKGROUND

The importance of sex and gender as modifiers of health and disease is increasingly recognized. The aim of this study was to analyze gender differences in incidence, tumor characteristics, treatment and relative survival (RS) in colorectal cancer (CRC).

METHODS

Observational population-based study including patients diagnosed with CRC in the Netherlands between 2010 and 2020. Stratified by localization (colon/rectum) and age (18-55/56-70/≥71years), gender differences in incidence, tumor characteristics, treatment and RS were analyzed. Multivariable regression was used to analyze the influence of gender on treatment and RS.

RESULTS

The age-standardized incidence per 100,000 person-years of colon and rectal cancer is higher among men than women (colon: 41.2 versus 32.4, rectum: 22.8 versus 12.6). Besides differences in patient- and tumor characteristics, differences in treatment allocation and RS were observed. Most strikingly, women aged ≥ 71 years with stage IV colon cancer are less often treated with systemic therapy (31.3 % versus 28.4 %, adjusted odds ratio (OR) 0.63, 95 % CI 0.48-0.83) and more often receive best supportive care only (47.6 % versus 40.0 %, adjusted OR 1.58, 95 % CI 1.19-2.11).

CONCLUSION

Statistically significant and clinically relevant gender differences in incidence, patient- and tumor characteristics and treatment allocation are observed in patients with CRC. Reasons for differences in treatment allocation deserve further investigation.

Web-based nomogram and risk stratification system constructed for predicting the overall survival of older adults with primary kidney cancer after surgical resection

BACKGROUND

Kidney cancer (KC) is one of the most common malignant tumors in adults which particularly affects the survival of elderly patients. We aimed to construct a nomogram to predict overall survival (OS) in elderly KC patients after surgery.

METHODS

Information on all primary KC patients aged more than 65 years and treated with surgery between 2010 and 2015 was downloaded from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox regression analysis was used to identify the independent prognostic factors. Consistency index (C-index), receiver operating characteristic curve (ROC), the area under curve (AUC), and calibration curve were used to assess the accuracy and validity of the nomogram. Comparison of the clinical benefits of nomogram and the TNM staging system is done by decision curve analysis (DCA) and time-dependent ROC.

RESULTS

A total of 15,989 elderly KC patients undergoing surgery were included. All patients were randomly divided into training set (N = 11,193, 70%) and validation set (N = 4796, 30%). The nomogram produced C-indexes of 0.771 (95% CI 0.751-0.791) and 0.792 (95% CI 0.763-0.821) in the training and validation sets, respectively, indicating that the nomogram has excellent predictive accuracy. The ROC, AUC, and calibration curves also showed the same excellent results. In addition, DCA and time-dependent ROC showed that the nomogram outperformed the TNM staging system with better net clinical benefits and predictive efficacy.

CONCLUSIONS

Independent influencing factors for postoperative OS in elderly KC patients were sex, age, histological type, tumor size, grade, surgery, marriage, radiotherapy, and T-, N-, and M-stage. The web-based nomogram and risk stratification system could assist surgeons and patients in clinical decision-making.

Factors Affecting the Rate of Colonoscopy Among African Americans Aged Over 45 Years

African Americans continue to have a low rate of colonoscopy screening despite the U.S. Preventive Services Taskforce's (USPSTF) recommendations and its proven benefits. Colonoscopy has proven to be an effective screening and therapeutic procedure. Understanding the root cause of the problem is a crucial step toward achieving the desired colonoscopy rate among this population. This paper evaluates factors that contribute to the underutilization of colonoscopy. The paper also analyzes strategies that could be maximized to increase colonoscopy rates, minimize colorectal cancer inequalities, and promote optimal colorectal health among African Americans.

Suicide rates among patients with first and second primary cancer

AIMS

With advancements in cancer treatments, the survival rates of patients with their first primary cancer (FPC) have increased, resulting in a rise in the number of patients with second primary cancer (SPC). However, there has been no assessment on the incidence of suicide among patients with SPC. This study assessed the occurrence of suicide among patients with SPC and compared them with that in patients with FPC.

METHODS

This was a retrospective, population-based cohort study that followed patients with FPC and SPC diagnosed from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) 17 registries database between 1 January 2000 and 31 December 2019.

RESULTS

For patients with SPC, an age of 85+ years at diagnosis was associated with a higher incidence of suicide death (HR, 1.727; 95% CI, 1.075-2.774), while the suicide death was not considerably different in the chemotherapy group (P > 0.05). Female genital system cancers (HR, 3.042; 95% CI, 1.819-6.361) accounted for the highest suicide death among patients with SPC. The suicide death distribution of patients with SPC over time indicated that suicide events mainly occurred within 5 to 15 years of diagnosis. Compared with patients with FPC, patients with SPC in general had a lower risk of suicide, but increased year by year.

CONCLUSION

The risk of suicide was reduced in patients with SPC compared with patients with FPC, but increased year by year. Therefore, oncologists and related health professionals need to provide continuous psychological support to reduce the incidence of suicide. The highest suicide death was found among patients with female genital system cancer.

Racial disparities in cancer care, an eyeopener for developing better global cancer management strategies

BACKGROUND

In the last few decades, advancements in cancer research, both in the field of cancer diagnostics as well as treatment of the disease have been extensive and multidimensional. Increased availability of health care resources and growing awareness has resulted in the reduction of consumption of carcinogens such as tobacco; adopting various prophylactic measures; cancer testing on regular basis and improved targeted therapies have greatly reduced cancer mortality among populations, globally. However, this notable reduction in cancer mortality is discriminate and reflective of disparities between various ethnic populations and economic classes. Several factors contribute to this systemic inequity, at the level of diagnosis, cancer prognosis, therapeutics, and even point-of-care facilities.

RECENT FINDINGS

In this review, we have highlighted cancer health disparities among different populations around the globe. It encompasses social determinants such as status in society, poverty, education, diagnostic approaches including biomarkers and molecular testing, treatment as well as palliative care. Cancer treatment is an active area of constant progress and newer targeted treatments like immunotherapy, personalized treatment, and combinatorial therapies are emerging but these also show biases in their implementation in various sections of society. The involvement of populations in clinical trials and trial management is also a hotbed for racial discrimination. The immense progress in cancer management and its worldwide application needs a careful evaluation by identifying the biases in racial discrimination in healthcare facilities.

CONCLUSION

Our review gives a comprehensive evaluation of this global racial discrimination in cancer care and would be helpful in designing better strategies for cancer management and decreasing mortality.

Impact of Head and Neck Cancer Diagnosis and Treatment on Patient-Partner Intimacy

OBJECTIVE

To determine the effects of head and neck squamous cell carcinoma diagnosis and treatment on patient- and partner-perceived intimacy and to understand if a diagnosis of HPV-related head and neck squamous cell carcinoma influences patient-partner intimacy.

STUDY DESIGN

Prospective observational.

SETTING

Single tertiary care center.

METHODS

An investigator-developed questionnaire was used to prospectively survey patients and partners in 2 groups based on human papillomavirus (HPV) status: HPV+ and HPV- at diagnosis (visit 1) and after treatment (visit 2). Surveys were scored on a 60-point scale, and results were categorized as follows: loss of intimacy (0-30), stable relationship (31-41), or improvement in intimacy (42-60). Responses of couples who participated together were assessed for concordance. Responses were considered discordant if patient and partner scores equated to different levels of perceived intimacy. Median patient and partner scores were compared via Mann-Whitney U test, and concordance was assessed with a chi-square test.

RESULTS

Thirty-four patients and 28 partners completed surveys at visit 1 and 28 patients and 15 partners at visit 2. Median scores among patients and partners were similar at the first time point (HPV+, 45 vs 45, P = .64; HPV-, 42.6 vs 40.8, P = .29) and the second (HPV+, 44.5 vs 44, P = .87; HPV-, 40.2 vs 39.6, P = .90). Concordance rates between HPV+ and HPV- couples were 63% vs 44% (P = .43) for the first time point and 89% vs 50% (P = .24) for the second.

CONCLUSION

Patients and partners reported stable or improved intimacy at both time points, and most couples tended to agree on their levels of perceived intimacy. A diagnosis of HPV did not appear to significantly affect intimacy scores.

Epidemiological and survival outcomes of neuroendocrine carcinoma of the breast: a SEER data analysis

BACKGROUND

Neuroendocrine carcinoma of the breast (NECB) is a rare subtype of breast cancer, comprising only 0.1% to 5% of all breast cancer cases. Despite its rarity, it is important to gain a better understanding of the epidemiological, clinical, and prognostic features of NECB. The purpose of the study was to obtain population-based evaluations of the epidemiological and survival outcomes of NECB.

METHODS

The data of patients with neuroendocrine carcinoma diagnosed and enrolled between 2000 and 2017 were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Descriptive statistical analyses were used to assess the distribution and tumor-related characteristics of these patients. Kaplan-Meier curves and univariate and multivariate Cox proportional risk models were used to analyze variables that might be associated with prognosis.

RESULTS

This study included 7,856 patients with neuroendocrine carcinoma. The median age of the patients was 64 years, and most of them were female, White, and diagnosed at ≥60 years old. The most common pathological type was neoplasm. Survival analysis indicated that there were significant differences in age, marital status, registration location, American Joint Committee on Cancer (AJCC) stage, breast subtype, surgery of primary tumor, and no cancer cause surgery patients with NECB. The results also indicated that treatment with surgery, including surgery of primary tumor, surgery combined with radiation, and no cancer cause surgery, were all effective in improving the prognosis compared with not providing surgical treatment.

CONCLUSIONS

In conclusion, NECB is a very rare lesion for which age, marital status, registration location, and surgery, AJCC stage, breast subtype were found to be independent prognostic factors.

Impact of Age, Race, and Gender on the Association Between Marital Status and Treatment Outcomes in Oral Tongue Squamous Cell Carcinomas

Background: The objective of this study is to assess whether the impact of marital status on oral tongue squamous cell carcinomas (OTSCC) prognosis varied by gender, age, and race. Methods: We examined the clinicopathological variables using chi-squared tests, and we evaluated the association between survival and different variables using the methods of Kaplan-Meier. Univariate and multivariate analyses were performed to determine the effects of each variable on survival. Results: A total of 5282 patients were analyzed. The rate of being married was higher among Asian or Caucasian, and this rate decreased with higher tumor stage. While both married male and female survivors benefit from their marital status, we found a differential in OS based on gender, with females benefiting more than males (male P = .038; female P = .009, respectively). Patients who were divorced/separated/widowed (male HR = 1.275, 95% CI: 1.085-1.499; female HR = 1.313, 95% CI: 1.083-1.593) and never married (male HR = 1.164, 95% CI: 0.983-1.378; female HR = 1.224, 95% CI: 0.958-1.565) had increased hazard of OS compared with married/partnered patients (male P = .038; female P = .009). Subgroups analysis shows that the effect of marital status was significantly associated with treatment outcome only in Caucasian patients aged 50 years or older who harbored non-metastatic disease and received surgery (P < .001). Conclusion: While there are survival benefits for married patients with OTSCC, married/partnered females may benefit more than males. Age, race, and gender could affect the correlation between marital status and survival.

Isoniazid preventive therapy completion and factors associated with non-completion among patients on antiretroviral therapy at Kisenyi Health Centre IV, Kampala, Uganda

BACKGROUND

Isoniazid preventive therapy (IPT) is given to HIV patients to reduce the risk of active tuberculosis (TB). However, treatment completion remains suboptimal among those that are initiated. This study aimed to determine the completion level of IPT and the factors associated with non-completion among patients on antiretroviral therapy (ART) at Kisenyi Health Center IV in Kampala, Uganda.

METHODS

A mixed-methods facility-based retrospective cohort study utilizing routinely collected data from 341 randomly selected HIV patients initiated on IPT was conducted. Data extracted from the registers was used to determine IPT completion. Robust Poisson regression was conducted to determine the associated factors of IPT non-completion, while in-depth interviews were conducted to explore barriers to IPT completion from the patient's perspective.

RESULTS

A total of 341 patients who started on isoniazid (INH) were retrospectively followed up, with 69% (236/341) being female. Overall IPT completion was 83%. Multivariate analysis revealed the prevalence of IPT non-completion among males was 2.24 times the prevalence among females (aPR 2.24, 95% CI: 1.40-3.58, p = 0.001). The prevalence of IPT non-completion among patients with a non-suppressed HIV viral load was 3.00 times the prevalence among those with a suppressed HIV viral load (aPR 3.00, 95% CI: 1.44-6.65, p = 0.007). The prevalence of IPT non-completion among patients who were married, or cohabiting was 0.31 times the prevalence among those who were single (aPR 0.31, 95% CI: 0.17-0.55, p<0.000). Lack of IPT-related health education, pill burden, distance to the health facility, and patient relocation were reported as barriers to IPT completion.

CONCLUSION

IPT completion was found to be 83% among the cohort studied. However, lower completion levels persist among males and HIV-virally non-suppressed patients. Lack of IPT-related health education, pill burden, distance to the health facility, and patient relocation were reported as barriers to IPT completion. Interventions that target these groups of people need to be intensified.

Predictors of Testicular Cancer Mortality in Brazil: A 20-Year Ecological Study

Testicular cancer is common in young men, and early detection and multimodality treatment can lead to successful outcomes. This study aims to identify sociodemographic and risk factors associated with higher testicular cancer mortality and poorer survival rates, while examining the impact of diagnostic and treatment procedures on reducing mortality. The retrospective ecological study analyzed mortality data from testicular cancer in Brazil from 2001 to 2020. Sociodemographic variables such as marital status, age, birth period, year of death (cohort), race, and geographic region were assessed. Risk factors included cryptorchidism and pesticide exposure. Data were subjected to statistical analysis, which revealed an increasing trend in mortality after 2011 among persons born after 1976 in the 15-40 age group. Individuals in the South Region, whites, and singles had higher age-standardized mortality rates (ASMRs), while singles had lower survival rates. The Northeast region had a higher survival rate. Fungicides and insecticides increase ASMR in Brazil. Herbicides increase ASMR in the Northeast and Midwest regions and insecticides increase ASMR in the Northeast, Southeast, and Midwest regions. High rates of implementation of diagnostic procedures in the Midwest were not sufficient to reduce ASMR. No treatment procedure was associated with mortality at the national or regional level.

Trusted residents and housing assistance to decrease violence exposure in New Haven (TRUE HAVEN): a strengths-based and community-driven stepped-wedge intervention to reduce gun violence

BACKGROUND

We describe the rationale and study design for "TRUsted rEsidents and Housing Assistance to decrease Violence Exposure in New Haven (TRUE HAVEN)," a prospective type 1 hybrid effectiveness/implementation study of a multi-level intervention using a stepped wedge design. TRUE HAVEN aims to lower rates of community gun violence by fostering the stability, wealth, and well-being of individuals and families directly impacted by incarceration through the provision of stable housing and by breaking the cycle of trauma.

DESIGN

TRUE HAVEN is an ongoing, multi-level intervention with three primary components: financial education paired with housing support (individual level), trauma-informed counseling (neighborhood level), and policy changes to address structural racism (city/state level). Six neighborhoods with among the highest rates of gun violence in New Haven, Connecticut, will receive the individual and neighborhood level intervention components sequentially beginning at staggered 6-month steps. Residents of these neighborhoods will be eligible to participate in the housing stability and financial education component if they were recently incarcerated or are family members of currently incarcerated people; participants will receive intense financial education and follow-up for six months and be eligible for special down payment and rental assistance programs. In addition, trusted community members and organization leaders within each target neighborhood will participate in trauma-informed care training sessions to then be able to recognize when their peers are suffering from trauma symptoms, to support these affected peers, and to destigmatize accessing professional mental health services and connect them to these services when needed. Finally, a multi-stakeholder coalition will be convened to address policies that act as barriers to housing stability or accessing mental healthcare. Interventions will be delivered through existing partnerships with community-based organizations and networks. The primary outcome is neighborhood rate of incident gun violence. To inform future implementation and optimize the intervention package as the study progresses, we will use the Learn As You Go approach to optimize and assess the effectiveness of the intervention package on the primary study outcome.

DISCUSSION

Results from this protocol will yield novel evidence for whether and how addressing structural racism citywide leads to a reduction in gun violence.

Early Death Incidence and Prediction Among Patients With Hypopharynx Squamous Cell Carcinomas

Background: The objective of this study is to evaluate the incidence and associated factors for early death (ED) in hypopharynx squamous cell carcinomas (SCC) patients. Materials and Methods: Patients were extracted from the Surveillance, Epidemiology and End Results database between 2004 and 2014. The ED (survival time ≤3 months) rate was calculated, and associated risk factors were evaluated by the logistic regression models. Results: A total of 2659 patients were analyzed and 307 (11.5%) patients died within 3 months after cancer diagnosis, among whom 243 (79.2%) patients died from cancer-specific cause. In univariate analyses, advanced age, divorced/single/widowed (DSW), non-Caucasian, advanced T classification, distant metastasis, and no surgery were significantly associated with ED (P < .05, respectively). Multivariate analyses showed that advanced age, DSW, advanced T classification, distant metastasis, and no surgery were significantly associated with all-cause and cancer-specific ED. Conclusion: Our results showed that a total of 11.5% patients with hypopharynx SCC suffered ED, among whom 79.2% patients died from cancer-specific cause. Predictors of ED are primarily related to age ≥62 years, advanced T classification, distant metastasis, and no surgery but also include unmarried status; better prognostic and predictive tools for select ED patients in larger sample size are needed.

Nomogram for predicting survival after lymphatic metastasis in esophageal cancer: A SEER analysis

Lymphatic metastasis (LM) is a significant mechanism for the spread of esophageal cancer (EC) and predicts the poor prognosis of EC patients. This research aimed to assess the survival of patients with LM from EC by developing a nomogram. In this retrospective study, EC patients with LM from 2004 to 2015 in the Surveillance, Epidemiology, and End Results (SEER) database were divided by year of diagnosis into a training cohort and a validation cohort. Univariate and multivariate Cox regression analyses were employed to determine the prognostic factors of LM, and a nomogram was constructed. The discrimination and calibration of the nomogram were compared by the C-index, area under the curve value, and calibration plots. The survival time difference was compared using Kaplan-Meier curves. A total of 11,695 patients with EC were included in this analysis. LM occurred in 56.5% (n = 6614) of EC patients. In the post-propensity score matching (PSM) cohort, patients with LM had significantly lower median overall survival (OS) than those without LM. Multivariate Cox regression was used to identify the eleven independent prognostic factors. The C-index was 0.709 in both the training and test sets, revealing the good predictive performance of the nomogram. Based on the results of calibration plots and the receiver operating characteristic (ROC) curve, we demonstrate the great performance of the prognostic model. The survival time of EC patients with LM was remarkably lower than that of EC patients without LM. The nomogram model established in this study can precisely predict the survival of EC patients with LM.

A SEER data-based nomogram for the prognostic analysis of survival of patients with Kaposi's sarcoma

Background

This study developed the first comprehensive nomogram for predicting the cancer-specific survival (CSS) of patients with Kaposi's sarcoma (KS).

Methods

Data on the demographic and clinical characteristics of 4143 patients with KS were collected from the Surveillance, Epidemiology, and End Results (SEER) database and used for the prognostic analysis. The patients were randomly divided into two groups: training cohort (n = 2900) and validation cohort (n = 1243). Multivariate Cox regression analysis was used to identify the predictive variables for developing the first nomogram for the survival prediction of patients with KS. The new survival nomogram was further evaluated using the concordance index (C-index), area under the time-dependent receiver operating characteristic curve (AUC), net reclassification improvement (NRI), integrated discrimination improvement (IDI), calibration plotting, and decision curve analysis (DCA).

Results

A nomogram was developed for determining the 3-, 5-, 8-, and 10-year CSS probabilities for patients with KS. The nomogram showed that tumor stage had the greatest influence on the CSS of patients with KS, followed by demographic variables (race, marital status, and age at diagnosis) and other clinical characteristics (surgery status, chemotherapy status, tumor risk classification, and radiotherapy status). The nomogram exhibited excellent performance based on the values of the C-index, AUC, NRI, and IDI as well as calibration plots. DCA further confirmed that the nomogram had good net benefits for 3-, 5-, 8-, and 10-year survival analyses.

Conclusions

In this study, by using data from the SEER database, we developed the first comprehensive nomogram for analyzing the survival of patients with KS. This nomogram could serve as a convenient and reliable tool for clinicians to predict CSS probabilities for individual patients with KS.

Racial disparities in conditional survival of patients with bladder cancer: a population-based study

BACKGROUND

Traditional estimates can only provide static predictions of cancer outcomes and cannot assess the evolving effect of race on patient survival. This study aims to reveal the dynamic survival of patients with bladder cancer and to explore the evolving effect of race on patient prognosis.

METHODS

Using data from the Surveillance, Epidemiology, and End Results (SEER) registry, 99,590 white, 6,036 African American, and 4,685 Asian/Pacific Islander (API) patients with bladder cancer were identified. Conditional cancer-specific survival (CSS) rates, which could reflect the dynamic survival prediction of cancer patients, represented the primary outcomes, and were estimated by the Kaplan-Meier algorithm. The evolving effect of race on patient survival was evaluated by multivariable Cox regression in combination with conditional survival (CS) estimates.

RESULTS

The 5-year CSS for African American patients who had survived 1, 2, 3, 4, or 5 years after definitive therapy improved from the baseline calculation by + 5.8 (84.4%), + 9.5 (87.4%), + 12.8 (90.0%), + 14.4 (91.3%), and + 14.7% (91.5%), respectively. The increasing trend also held for overall white and API patients, and for all patient subsets when CS was calculated according to different levels of sex, age, and disease stage. African Americans, despite having the worst survival at baseline, could have CSS comparable to their white and API counterparts after 4 years of survivorship. In addition, the risk of death for African Americans tended to decrease with increasing survival, and the risk was no longer significantly different from that of whites after 4 years of survival.

CONCLUSIONS

While having the worst initial predicted outcomes, African Americans may eventually achieve comparable survival to white and API patients given several years of survivorship. As patient survival increases, African American race may lose its role as an indicator of poorer prognosis.

Association between marital status and all-cause mortality of patients with metastatic breast cancer: a population-based study

This study aimed to investigate the association between marital status and the prognosis of patients with metastatic breast cancer (MBC). Data of patients with MBC were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified into married and unmarried groups. Kaplan-Meier analysis with the log-rank test was conducted to compare breast cancer-specific survival (BCSS) and overall survival (OS) between the groups. Univariable and multivariable Cox proportional models were used to determine whether marital status was independently associated with OS, and the Fine-Gray subdistribution hazard method was performed to determine whether marital status was independently associated with BCSS. In total, 16,513 patients with MBC were identified, including 8949 married (54.19%) and 7564 unmarried (45.81%) patients. The married patients were significantly younger [median age (interquartile range), 59.0 (50.0-68.0) vs. 63.0 (53.0-75.0); p < 0.001] and received more aggressive treatments, such as chemotherapy (p < 0.001) and surgery (p < 0.001), than the unmarried patients. Moreover, married patients had higher 5-year BCSS (42.64% vs. 33.17%, p < 0.0001) and OS (32.22% vs. 21.44%, p < 0.0001) rates. Multivariable analysis revealed that marital status was an independent prognostic factor, and married status was associated with a significant reduction in the risk of breast cancer-specific (sub-hazard ratio, 0.845; 95% confidence interval, 0.804-0.888; p < 0.001) and all-cause (hazard ratio, 0.810; 95% confidence interval, 0.777-0.844; p < 0.001) mortality. Unmarried patients had a 15.5% increased risk of breast cancer-specific mortality and a 19.0% increased risk of overall mortality compared with married patients with MBC. BCSS and OS were superior in married populations compared with unmarried populations in most subgroups. Marital status was an independent prognostic indicator for survival in patients with MBC and was associated with significant survival benefits.

Unknown Causes of Death in Cancer Patients

OBJECTIVES

Deaths from an unknown cause are difficult to adjudicate and oncologic studies of comparative effectiveness often demonstrate inconsistencies in incorporating these deaths and competing events (eg, heart disease and stroke) in their analyses. In this study, we identify cancer patients most at risk for death of an unknown cause.

METHODS

This retrospective, population-based study used cancer registry data from the Surveillance, Epidemiology, and End Results database (1992-2015). The absolute rate of unknown causes of death (COD) cases stratified by sex, marital status, race, treatment, and cancer site were calculated and a multivariable logistic regression model was applied to obtain adjusted odds ratios with 95% CIs.

RESULTS

Out of 7,154,779 cancer patients across 22 cancer subtypes extracted from Surveillance, Epidemiology, and End Results, 3,448,927 died during follow-up and 276,068 (7.4%) of these deaths were from unknown causes. Patients with an unknown COD had a shorter mean survival time compared with patients with known COD (36.3 vs 65.7 mo, P < 0.001). The contribution of unknown COD to total mortality was highest in patients with more indolent cancers (eg, prostate [12.7%], thyroid [12.3%], breast [10.7%]) and longer follow-up (eg, >5 to 10 y). One, 3, and 5-year cancer-specific survival (CSS) calculations including unknown COD were significantly decreased compared with CSS estimates excluding cancer patients with unknown COD.

CONCLUSION

Of the patients, 7.4% died of unknown causes during follow-up and the proportion of death was higher with longer follow-up and among more indolent cancers. The attribution of high percentages of unknown COD to cancer or non-cancer causes could impact population-based cancer registry studies or clinical trial outcomes with respect to measures involving CSS and mortality.

A novel risk prediction nomogram for early death in patients with resected synchronous multiple primary colorectal cancer based on the SEER database

BACKGROUND

Synchronous multiple primary colorectal cancer (SMPCC) involves the simultaneous occurrence of 2 or more independent primary malignant tumors in the colon or rectum. Although SMPCC is rare, it results in a higher incidence of postoperative complications and mortality compared to patients with single primary colorectal cancer (SPCRC).

METHODS

The clinical factors and survival outcomes of SMPCC patients registered on the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2017 were extracted. The patients were divided into the training and validation cohorts using a ratio of 7:3. Univariate and multivariate logistic regression analyses were used to identify the independent risk factors for early death. The performance of the nomogram was evaluated using the concordance index (C-index), calibration curves, and the area under the curve (AUC) of a receiver operating characteristics curve (ROC). A decision curve analysis (DCA) was used to evaluate the clinical utility of the nomogram and standard TNM system.

RESULTS

A total of 4386 SMPCC patients were enrolled in the study and randomly assigned to the training (n = 3070) and validation (n = 1316) cohorts. The multivariate logistic analysis identified age, chemotherapy, radiotherapy, T stage, N stage, and M stage as independent risk factors for all-cause and cancer-specific early death. The marital status was associated with all-cause early death, and the tumor grade was associated with cancer-specific early death. In the training cohort, the nomogram achieved a C-index of 0.808 (95% CI, 0.784-0.832) and 0.843 (95% CI, 0.816-0.870) for all-cause and cancer-specific early death, respectively. Following validation, the C-index was 0.797 (95% CI, 0.758-0.837) for all-cause early death and 0.832 (95% CI, 0.789-0.875) for cancer-specific early death. The ROC and calibration curves indicated that the model had good stability and reliability. The DCA showed that the nomogram had a better clinical net value than the TNM staging system.

CONCLUSION

Our nomogram can provide a simple and accurate tool for clinicians to predict the risk of early death in SMPCC patients undergoing surgery and could be used to optimize the treatment according to the patient's needs.

Comparison of survival outcomes of different treatment modalities for patients with primary splenic diffuse large B cell lymphoma

Primary splenic diffuse large B cell lymphoma (DLBCL) is one of the most common primary tumors in the spleen, while its prevalence is relatively low. Recently, there has been an increase in the incidence rate of primary splenic DLBCL; however, the effectiveness of various treatments for it has not been adequately described previously. The purpose of this study was to compare the effectiveness of various treatments on survival time in primary splenic DLBCL. A total of 347 patients with primary splenic DLBCL were enrolled in The Surveillance, Epidemiology, and End Results (SEER) database. These patients were subsequently divided into four subgroups according to the treatment modalities: non-treatment group (patients who had not received chemotherapy, radiotherapy, or splenectomy, n=19), splenectomy group (patients who had received splenectomy only, n=71), chemotherapy group (patients who had received chemotherapy only, n=95), and the splenectomy combined with chemotherapy group (patients who had received splenectomy and chemotherapy, n=162). The overall survival (OS) and cancer specific survival (CSS) of four treatment groups were evaluated. Compared to the splenectomy group and the non-treatment group, the OS and CSS of the splenectomy combined with chemotherapy group was extremely significantly prolonged (P<0.01). Compared with the chemotherapy group, the OS and CSS of the splenectomy combined with chemotherapy group were longer, but there was no statistical difference (P>0.05). The Cox regression analysis showed that the treatment modality was identified as an independent prognostic factor for primary splenic DLBCL. The landmark analysis shows that the overall cumulative mortality risk was significantly lower in the splenectomy combined with chemotherapy group than in the chemotherapy group within 30 months (P<0.05), and the cancer-specific mortality risk was significantly lower in the splenectomy combined with chemotherapy group than in the chemotherapy group within 19 months (P<0.05). Splenectomy combined with chemotherapy may be the most effective treatment modality for primary splenic DLBCL.

Primary blastic plasmacytoid dendritic cell neoplasm: a US population-based study

Background

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and poorly understood hematopoietic malignancy. This study aimed to investigate the clinical characteristics and prognostic factors in patients with primary BPDCN.

Methods

Patients diagnosed with primary BPDCN from 2001 to 2019 were extracted from the Surveillance, Epidemiology and End Results (SEER) database. Survival outcome was analysed with Kaplan-Meier method. Prognostic factors were evaluated based on the univariate and multivariate accelerated failure time (AFT) regression analysis.

Results

A total of 340 primary BPDCN patients were included in this study. The average age was 53.7 ± 19.4 years, with 71.5% being male. The mostly affected sites were lymph nodes (31.8%). Most patients (82.1%) received chemotherapy, while 14.7% received radiation therapy. For all the patients, the 1-year, 3-year, 5-year, and 10-year overall survival (OS) were 68.7%, 49.8%, 43.9%, and 39.2%, respectively, and the corresponding disease-specific survival (DSS) were 73.6%, 56.0%, 50.2%, and 48.1%, respectively. Univariate AFT analysis showed that older age, marital status of divorced, widowed and separated at diagnosis, primary BPDCN only, treatment delay for 3-6 months and without radiation therapy were significantly associated with poor prognosis of primary BPDCN patients. But multivariate AFT analysis indicated that older age was independently associated with worse survival, while second primary malignancies (SPMs) and radiation therapy were independently associated with extended survival.

Conclusions

Primary BPDCN is a rare disease with poor prognosis. Advanced age was linked independently to poorer survival, while SPMs and radiation therapy were linked independently to prolonged survival.

TRUsted rEsidents and Housing Assistance to decrease Violence Exposure in New Haven (TRUE HAVEN): A strengths-based and community-driven stepped-wedge intervention to reduce gun violence

Background We describe the rationale and study design for " TRU sted r Esidents and H ousing A ssistance to decrease V iolence E xposure in N ew Haven (TRUE HAVEN)," a prospective type 1 hybrid effectiveness/implementation study of a multi-level intervention using a stepped wedge design. TRUE HAVEN aims to lower rates of community gun violence by fostering the stability, wealth, and well-being of individuals and families directly impacted by incarceration through the provision of stable housing and by breaking the cycle of trauma. Design: TRUE HAVEN is a multi-level intervention with three primary components: financial education paired with housing support (individual level), trauma-informed counseling (neighborhood level), and policy changes to address structural racism (city/state level). Six neighborhoods with among the highest rates of gun violence in New Haven, Connecticut, will receive the individual and neighborhood level intervention components sequentially beginning at staggered 6-month steps. Residents of these neighborhoods will be eligible to participate in the housing stability and financial education component if they were recently incarcerated or are family members of currently incarcerated people; participants will receive intense financial education and follow-up for six months and be eligible for special down payment and rental assistance programs. In addition, trusted community members and organization leaders within each target neighborhood will participate in trauma-informed care training sessions to then be able to recognize when their peers are suffering from trauma symptoms, to support these affected peers, and to destigmatize accessing professional mental health services and connect them to these services when needed. Finally, a multi-stakeholder coalition will be convened to address policies that act as barriers to housing stability or accessing mental healthcare. Interventions will be delivered through existing partnerships with community-based organizations and networks. The primary outcome is neighborhood rate of incident gun violence. To inform future implementation and optimize the intervention package as the study progresses, we will use the Learn As You Go approach to optimize and assess the effectiveness of the intervention package on the primary study outcome. Discussion Results from this protocol will yield novel evidence for whether and how addressing structural racism citywide leads to a reduction in gun violence. Trial registration ClinicalTrials.gov Identifier: NCT05723614. Registration date: February 01, 2023.

Natural Language Processing Methods to Empirically Explore Social Contexts and Needs in Cancer Patient Notes

PURPOSE

There is an unmet need to empirically explore and understand drivers of cancer disparities, particularly social determinants of health. We explored natural language processing methods to automatically and empirically extract clinical documentation of social contexts and needs that may underlie disparities.

METHODS

This was a retrospective analysis of 230,325 clinical notes from 5,285 patients treated with radiotherapy from 2007 to 2019. We compared linguistic features among White versus non-White, low-income insurance versus other insurance, and male versus female patients' notes. Log odds ratios with an informative Dirichlet prior were calculated to compare words over-represented in each group. A variational autoencoder topic model was applied, and topic probability was compared between groups. The presence of machine-learnable bias was explored by developing statistical and neural demographic group classifiers.

RESULTS

Terms associated with varied social contexts and needs were identified for all demographic group comparisons. For example, notes of non-White and low-income insurance patients were over-represented with terms associated with housing and transportation, whereas notes of White and other insurance patients were over-represented with terms related to physical activity. Topic models identified a social history topic, and topic probability varied significantly between the demographic group comparisons. Classification models performed poorly at classifying notes of non-White and low-income insurance patients (F1 of 0.30 and 0.23, respectively).

CONCLUSION

Exploration of linguistic differences in clinical notes between patients of different race/ethnicity, insurance status, and sex identified social contexts and needs in patients with cancer and revealed high-level differences in notes. Future work is needed to validate whether these findings may play a role in cancer disparities.

Clinical outcomes of adjuvant taxane plus anthracycline versus taxane-based chemotherapy regimens in older adults with node-positive, triple-negative breast cancer: A SEER-Medicare study

BACKGROUND

Triple-negative breast cancer (TNBC) is a subtype of breast cancer associated with an aggressive clinical course. Adjuvant chemotherapy reduces the risk of recurrence and improves survival in patients with node-positive TNBC. The benefit of anthracycline plus taxane (ATAX) regimens compared with non-anthracycline-containing, taxane-based regimens (TAX) in older women with node-positive TNBC is not well characterised.

METHODS

Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified 1106 women with node-positive TNBC diagnosed at age 66 years and older between 2010 and 2015. We compared patient clinical characteristics according to adjuvant chemotherapy regimen (chemotherapy versus no chemotherapy and ATAX versus TAX). Logistic regression was performed to estimate the odds ratios (OR) and 95% confidence intervals (CIs). Kaplan-Meier survival curves were generated to estimate 3-year overall survival (OS) and cancer-specific survival (CSS). Cox proportional hazard models were used to analyse OS and CSS while controlling for patient and tumour characteristics.

RESULTS

Of the 1106 patients in our cohort, 767 (69.3%) received adjuvant chemotherapy with ATAX (364/767, 47.5%), TAX (297/767, 39%) or other regimens (106/767, 13.8%). Independent predictors of which patients were more likely to receive ATAX versus TAX included more extensive nodal involvement (≥4), age, marital/partner status and non-cardiac comorbidities. There was a statistically significant improvement in 3-year CSS (81.8% versus 71.4%) and OS (70.7% versus 51.3%) with the use of any chemotherapy in our cohort (P < 0.01). Three-year CSS and OS for patients who received ATAX versus TAX were similar at 82.8% versus 83.7% (P = 0.80) and 74.2% versus 72.7% (P = 0.79), respectively. There was a trend towards improved CSS and OS in patients with four or more positive lymph nodes who received ATAX versus TAX (hazard ratio 0.66, 95% CI: 0.36-1.23, P = 0.19 and hazard ratio 0.68, 95% CI: 0.41-1.14, P = 0.14, respectively).

CONCLUSION

Among older women with node-positive TNBC, a majority of patients received adjuvant chemotherapy, which was associated with an improvement in CSS and OS. When compared with TAX chemotherapy, there was a trend towards better outcomes with ATAX for patients with ≥4 nodes.

Marital status is an independent prognostic factor for cervical adenocarcinoma: A population-based study

Marriage has been reported as a beneficial factor associated with improved survival among cancer patients, but conflicting results have been observed in cervical adenocarcinoma (AC). Thus, this study is aimed to examine the relationship between the prognosis of cervical AC and marital status. Eligible patients were selected from 2004 to 2015 using the surveillance, epidemiology and end results (SEER) database. Cancer-specific survival (CSS) and overall survival (OS) were compared between married and unmarried groups. A total of 3096 patients had been identified, with married ones accounting for 51.29% (n = 1588). Compared to unmarried groups, more patients in the married group were relatively younger (aged ≤ 45) and belonged to white race, with grade I/II, Federation of International of Gynecologists and Obstetricians (FIGO) stage I/II and tumor size ≤4 cm. Apart from that, more patients received surgery, whereas fewer patients received chemotherapy and radiotherapy (all P < 0.05). The 5-year CSS and OS rates were 80.16% and 78.26% in married patients, 68.58% and 64.62% in the unmarried group (P < .0001). Multivariate analysis showed that marital status was an independent prognostic factor, and the married group performed better CSS (hazard ratio [HR]: 0.770; 95% confidence interval [CI]: 0.663-0.895; P = .001) as well as OS (HR: 0.751; 95%CI: 0.653-0.863; P < .001). As demonstrated by the results of subgroup analysis, married patients had better CSS and OS survival than unmarried ones in nearly all the subgroups. Marital status was identified as an independent prognostic factor for improved survival in patients with cervical AC.

Screening practices of cancer survivors and individuals whose family or friends had a cancer diagnoses-a nationally representative cross-sectional survey in Japan (INFORM Study 2020)

PURPOSE

We examined cancer screening practices and related beliefs in cancer survivors and individuals with family or close friends with a cancer diagnosis compared to individuals without the above cancer history for 5 population-based (gastric, colorectal, lung, breast, cervical) and 1 opportunistic (prostate) cancer screenings using nationally representative cross-sectional survey in Japan.

METHODS

We analyzed 3269 data from 3605 respondents (response rate, 37.1%) and compared the screening beliefs and practices of cancer survivors (n = 391), individuals with family members (n = 1674), and close friends with a cancer diagnosis (n = 685) to those without any cancer history (n = 519).

RESULTS

Being a cancer survivor was associated with screening for gastric (OR, 1.75; 95% CI, 1.04-2.95), colorectal (OR, 1.56; 95% CI, 1.03-2.36), and lung cancer (OR, 1.71; 95% CI, 1.10-2.66) but not breast, cervical cancer or PSA test. Having a family cancer diagnosis was associated with colorectal and lung cancer screening. Having friends with a cancer diagnosis was associated with PSA test. Cancer survivors and family members perceived themselves as being more susceptible and worried about getting cancer than individuals without any cancer history. Cancer survivors strongly believed screening can detect cancer and were more likely to undergo screening. Subgroup analysis indicated an interrelation between gastric and colorectal cancer screening among survivors.

CONCLUSIONS

A cancer diagnosis in oneself or family or friend influences an individual's health-related belief and risk perception, which can increase the likelihood of cancer screening.

IMPLICATIONS FOR CANCER SURVIVORS

Targeted and tailored communication strategies can increase awareness of cancer screening.

Relationship Functioning and Gut Microbiota Composition among Older Adult Couples

An emerging area of research extends work on couple functioning and physical health to gut health, a critical marker of general health and known to diminish with age. As a foray into this area, we conducted a pilot study to (1) determine the feasibility of remote data collection, including a fecal sample, from older adult couples, (2) examine within-couple concordance in gut microbiota composition, and (3) examine associations between relationship functioning and gut microbiota composition. Couples (N = 30) were recruited from the community. The participants' demographic characteristics were as follows: M (SD) age = 66.6 (4.8), 53% female, 92% White, and 2% Hispanic. Two of the couples were same-sex. All 60 participants completed self-report measures and supplied a fecal sample for microbiome analysis. Microbial DNA was extracted from the samples, and the 16S rRNA gene V4 region was amplified and sequenced. The results indicated that individuals shared more similar gut microbial composition with their partners than with others in the sample, p < 0.0001. In addition, individuals with better relationship quality (greater relationship satisfaction and intimacy and less avoidant communication) had greater microbial diversity, p < 0.05, a sign of healthier gut microbiota. Further research with a larger and more diverse sample is warranted to elucidate mechanisms.

Application of artificial intelligence for overall survival risk stratification in oropharyngeal carcinoma: A validation of ProgTOOL

BACKGROUND

In recent years, there has been a surge in machine learning-based models for diagnosis and prognostication of outcomes in oncology. However, there are concerns relating to the model's reproducibility and generalizability to a separate patient cohort (i.e., external validation).

OBJECTIVES

This study primarily provides a validation study for a recently introduced and publicly available machine learning (ML) web-based prognostic tool (ProgTOOL) for overall survival risk stratification of oropharyngeal squamous cell carcinoma (OPSCC). Additionally, we reviewed the published studies that have utilized ML for outcome prognostication in OPSCC to examine how many of these models were externally validated, type of external validation, characteristics of the external dataset, and diagnostic performance characteristics on the internal validation (IV) and external validation (EV) datasets were extracted and compared.

METHODS

We used a total of 163 OPSCC patients obtained from the Helsinki University Hospital to externally validate the ProgTOOL for generalizability. In addition, PubMed, OvidMedline, Scopus, and Web of Science databases were systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

The ProgTOOL produced a predictive performance of 86.5% balanced accuracy, Mathew's correlation coefficient of 0.78, Net Benefit (0.7) and Brier score (0.06) for overall survival stratification of OPSCC patients as either low-chance or high-chance. In addition, out of a total of 31 studies found to have used ML for the prognostication of outcomes in OPSCC, only seven (22.6%) reported a form of EV. Three studies (42.9%) each used either temporal EV or geographical EV while only one study (14.2%) used expert as a form of EV. Most of the studies reported a reduction in performance when externally validated.

CONCLUSION

The performance of the model in this validation study indicates that it may be generalized, therefore, bringing recommendations of the model for clinical evaluation closer to reality. However, the number of externally validated ML-based models for OPSCC is still relatively small. This significantly limits the transfer of these models for clinical evaluation and subsequently reduces the likelihood of the use of these models in daily clinical practice. As a gold standard, we recommend the use of geographical EV and validation studies to reveal biases and overfitting of these models. These recommendations are poised to facilitate the implementation of these models in clinical practice.

Marital status and perceived stress in men with advanced prostate cancer: A randomized-controlled trial of cognitive behavioral stress management

OBJECTIVE

Relationship status predicts numerous outcomes among medical populations. Few interventions evaluate the role of marital status on response to psychosocial treatment, and no such studies exist within advanced prostate cancer (APC). This study examined whether marital status modified the effect of a cognitive behavioral stress management (CBSM) intervention on perceived stress.

METHODS

Men with APC (N = 190) were randomized to 10-week CBSM or a health promotion (HP) intervention (#NCT03149185). The Perceived Stress Scale assessed perceived stress at baseline and 12-month follow-up. Medical status and sociodemographics were captured at enrollment.

RESULTS

Participants were mostly White (59.5%), non-Hispanic (97.4%), heterosexual (97.4%) men, 66.8% of whom were partnered. Neither condition nor marital status predicted perceived stress change at follow-up. However, a significant interaction was found between condition and marital status (p = 0.014; Cohen's f = 0.07), such that partnered men who received CBSM and unpartnered men who received HP reported greater reductions in perceived stress.

CONCLUSION

This is the first study to assess the impact of marital status on psychosocial intervention effects among men with APC. Partnered men derived greater benefit from a cognitive-behavioral intervention and unpartnered men equally benefitted from a HP intervention. Further research is necessary to understand the mechanisms underlying these relationships.

Health and Well-Being Needs Among Head and Neck Cancer Caregivers - A Systematic Review

OBJECTIVE

This review provides a summary of the current understanding of the health and well-being of the head and neck cancer (HNC) caregiver. Our goal is to understand the healthcare needs required by the caregivers of our oncologic patients, which may ultimately influence quality of care and support that cancer patients require during treatment and recovery.

METHODS

Independent database searches were conducted to identify articles describing HNC caregiver health and healthcare utilization. Search terms included key synonyms for head and neck cancer, caregiver, psychological stress, anxiety, depression, mental health service, and delivery of healthcare in the title/abstract.

RESULTS

After following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Protocol, a total of 21 studies were included. Among the 21 studies in the review, a total of 1745 caregivers were included. The average age was 57 years, the majority were female (58%-100%), and spouses/partners of the patients (77%). The literature demonstrates significant anxiety, depression, post-traumatic stress disorder (PTSD), and physical health decline in addition to multifaceted unmet physical and mental health needs among HNC caregivers.

CONCLUSION

There is no standard for examining HNC caregiver healthcare needs, while there is evidence of increased healthcare utilization. The literature is limited regarding medical burdens faced by caregivers. Future research is needed to assess the physical health and comorbidities of HNC caregivers and their engagement with the healthcare system to guide further implementation of support models to address the needs of this population.

Establishment and validation of systematic prognostic nomograms in patients over 60 years of age with osteosarcoma: A multicenter external verification study

BACKGROUND

The aim of this study was to develop and validate systematic nomograms to predict cancer specific survival (CSS) and overall survival (OS) in osteosarcoma patients aged over 60 years.

METHODS

We used data from the Surveillance, Epidemiology, and End Results (SEER) database and identified 982 patients with osteosarcoma over 60 years of age diagnosed between 2004 and 2015. Overall, 306 patients met the requirements for the training group. Next, we enrolled 56 patients who met the study requirements from multiple medical centers as the external validation group to validate and analyze our model. We collected all available variables and finally selected eight that were statistically associated with CSS and OS through Cox regression analysis. Integrating the identified variables, we constructed 3- and 5-year OS and CSS nomograms, respectively, which were further evaluated by calculating the C-index. A calibration curve was used to evaluate the accuracy of the model. Receiver operating characteristic (ROC) curves measured the predictive capacity of the nomograms. The Kaplan-Meier analysis was used for all patient-based variables to explore the influence of various factors on patient survival. Finally, a decision curve analysis (DCA) curve was used to analyze whether our model would be suitable for application in clinical practice.

RESULTS

Cox regression analysis of clinical variables identified age, sex, marital status, tumor grade, tumor laterality, tumor size, M-stage, and surgical treatment as prognostic factors. Nomograms showed good predictive capacity for OS and CSS. We calculated that the C-index of the OS nomogram of the training population was 0.827 (95% CI 0.778-0.876), while that of the CSS nomogram was 0.722 (95% CI 0.665-0.779). The C-index of the OS nomogram evaluated on the external validation population was 0.716 (95% CI 0.575-0.857), while that of the CSS nomogram was 0.642 (95% CI 0.50-0.788). Furthermore, the calibration curve of our prediction models indicated the nomograms could accurately predict patient outcome.

CONCLUSIONS

The constructed nomogram is a useful tool for accurately predicting OS and CSS at 3 and 5 years for patients over 60 years of age with osteosarcoma and can assist clinicians in making appropriate decisions in practice.

The Impact of Social Determinants of Health, Namely Financial Assistance, on Overall Survival in Advanced-Stage Non-Small Cell Lung Cancer Patients

PURPOSE

Non-small cell lung cancer (NSCLC) is the most prevalent form of lung cancer. Studies have evaluated the association of social determinants of health (SDH) with outcomes in early-stage NSCLC. These studies have shown statistically and clinically significant associations between overall survival (OS) and other SDH (e.g marital status, educational attainment).The aim of our study was to better understand the role of various SDH on OS in advanced-stage NSCLC patients in a community oncology practice in Florida.  Methods: In this retrospective study, 125 patients with stage III and IV NSCLC were identified between January 1, 2014, and December 31, 2018. We performed Pearson's chi-square and Kruskal-Wallis test to evaluate the association between median OS and several independent variables, including; gender, race, marital status, insurance status, living status, receiving financial assistance (FA), alcohol use, and smoking histories. OS is defined as the date of diagnosis up to the date of death. Other confounders that were analyzed included histology, treatment modality, comorbidities, and performance status of the patients.  Results: Our results demonstrated that patients receiving FA had nearly a two-fold increase in median OS compared to patients without FA (median OS = 1.01 years vs. 0.545 years, respectively; p = 0.012).

CONCLUSION

Overall, this study highlighted the importance of reducing the financial burden of advanced-stage NSCLC on patients and how FA impacts patient outcomes. However, future prospective cohort studies with a larger sample size are warranted to identify other SDH, as well as the underlying mechanisms affecting median OS, in patients with advanced-stage NSCLC.

Oral health related quality of life of oral cancer patients treated with radiotherapy alone or with chemotherapy in a tertiary referral centre in Sri Lanka

BACKGROUND

Oral cancer is the number one cancer among males in Sri Lanka. Radiotherapy is a common treatment modality for oral cancer, but this can affect oral health related quality of life (OHRQOL). This study assessed the OHRQOL and its changes from baseline to the last week of radiotherapy and three months post radiotherapy among oral cancer patients who received this treatment alone or with chemotherapy.

METHODS

A prospective longitudinal study was conducted among 90 oral cancer patients awaiting for radiotherapy alone or with chemotherapy. The modified Sinhala version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Oral Health Module (EORTC QLQ-OH15) was used to gather data related to OHRQOL before radiotherapy. Socio-demographic and clinical data were also recorded. The same cohort of patients were followed up and assessed their OHRQOL during the last week of radiotherapy and three months post radiotherapy. The Modified EORTC QLQ-OH15 assesses the OHRQOL under three domains namely 'Eating problem', 'Gum and speech problem' and 'Soreness', and one item named as 'Teeth'.

RESULTS

The majority of the sample (88%) was males. The anterior two-thirds of the tongue (40%) and buccal mucosa (22%) were the most common sites. The median scores of 'Eating problem' domain at baseline, last week of radiotherapy and three months post radiotherapy were 20 (IQR = 6.7-33.3), 100 (IQR = 86.9-100.0) and 66.7 (IQR = 46.7-93.3) respectively. 'Gum and speech problem' was higher during last week of radiotherapy (median, 50.0, IQR, 25.0-58.3) than three months post radiotherapy (median, 8.3, IQR, 0.0-33.3). The changes of OHRQOL between the time frames were statistically significant (p < 0.05). Baseline OHRQOL in relation to 'Gum and speech problem' domain and 'Teeth' item was identified as an influential factor for OHRQOL during last week of radiotherapy.

CONCLUSION

The OHRQOL of oral cancer patients who received radiotherapy alone or with chemotherapy had deteriorated from the baseline level to the last week of radiotherapy but then improved at three months post radiotherapy. The OHRQOL however did not return to the baseline level three months post radiotherapy. OHRQOL during the last week of radiotherapy was influenced by the OHRQOL at baseline, civil status and sites of metastasis.

Spiradenocarcinoma: SEER Study of Epidemiology, Survival, and Treatment Options

(1) Background: Spiradenocarcinoma is an extremely rare malignant adnexal tumor and there are only few studies on survival outcomes. Our aim was to perform an analysis of the demographic and pathological characteristics, treatment patterns, and survival outcomes of patients affected by spiradenocarcinoma. (2) Methods: The Surveillance, Epidemiology, and End Results program database of the National Cancer Institute was searched for all cases of spiradenocarcinoma diagnosed between 2000 and 2019. This database is considered representative of the US population. Demographic, pathological, and treatment variables were retrieved. Overall and disease-specific survival were computed according to the different variables. (3) Results: 90 cases of spiradenocarcinoma (47 females, 43 males) were identified. Mean age at diagnosis was 62.8 years. Regional and distant disease at diagnosis were rare, occurring in 2.2% and 3.3% of cases, respectively. Surgery alone was the most frequent treatment (87.8%), followed by a combination of surgery and radiotherapy (3.3%) and radiation therapy only (1.1%). Five-year overall survival was 76.2% and five-year disease-specific survival was 95.7%. (4) Conclusions: Spiradenocarcinoma equally affects males and females. Regional and distant invasion rates are low. Disease-specific mortality is low and is probably overestimated in the literature. Surgical excision remains the main form of treatment.

Specific organ metastases and prognosis in lung adenocarcinoma

OBJECTIVES

This study aims to characterize the specific organ metastatic rates in lung adenocarcinoma (LUAD) patients and identify the prognosis-associated factors.

METHODS

Using the Surveillance, Epidemiology and End Results database, 40 117 patients diagnosed with positive histology as the only primary LUAD were included. We stratified patients by diagnosed year, age, sex, race/ethnicity, marital status, insurance, location, TNM stage, organ-specific metastases, surgery, chemotherapy, and radiation therapy. We performed multivariable logistic and Cox regression to identify the factors associated with the presence of specific organ metastases and prognosis predictors.

RESULTS

For the 40 117 LUAD patients, 43.69%, 26.25%, 19.66%, 10.60%, and 17.89% had specific organ, bone, brain, liver, and lung metastases, respectively. The average survival in patients with organ metastases was 12.19 months, compared to 36.40 months in patients without metastases. In different kinds of metastatic organ cohorts, the longest average survival was 12.60 months in the lung metastases cohort, and the shortest was 8.43 months in liver metastases cohort. In total, 571 patients with metastases received surgery, which was significantly associated with decreased mortality (hazard ratio 1.82, 95% confidence interval 1.65-2.01, p < 0.01). Patients received surgery of lobectomy or extended (251 of 571, 43.96%) displayed the longest average survival (35.16 months); patients (294 of 571, 51.49%) received sub-lobar resection, had the average survival (19.90 months); patients received local tumor destruction (26 of 571, 4.55%) had the shortest average survival (13.73 months).

CONCLUSION

This study provides insights into the specific organ metastatic rates and prognosis in LUAD patients on a population level. These findings suggest that surgery resection should be taken into consideration in the treatment for these LUAD patients.

Nomograms for predicting survival in patients with micropapillary bladder cancer: a real-world analysis based on the surveillance, epidemiology, and end results database and external validation in a tertiary center

BACKGROUND

The present study aimed to construct and validate nomograms that can be used to predict cancer-specific survival (CSS) and overall survival (OS) in patients with micropapillary bladder cancer.

METHODS

The data of 627 patients diagnosed with micropapillary bladder cancer between 2000 and 2018 were obtained from the surveillance, epidemiology, and end results database. Patients were randomly divided into the training and internal validation sets (7:3). The Cox proportional hazards regression model was applied to evaluate the association between variables and survival and then nomograms were constructed to predict the survival of an individual patient. The performance of nomograms was validated by using calibration curves, concordance index, receiver operating characteristic curves with the calculated area under the curve and decision curve analysis in the training and internal validation set. Data from 41 micropapillary bladder cancer patients at Qilu Hospital of Shandong University from 2000 to 2022 were collected for external validation.

RESULTS

Several independent risk factors were taken into the two nomograms (CSS and OS), including age, marital status, AJCC TMN stage, surgical approach, lymph node ratio, and tumor size while the OS nomogram additionally contained race. The concordance index of the training set, internal validation set, and external verification set were all over 0.7. The calibration curve indicated good consistence between the nomogram prediction and actual survival. Area under the curve and decision curve analysis results indicated great clinical usefulness of nomograms.

CONCLUSIONS

The nomograms predicting the survival outcome of patients with micropapillary bladder cancer would provide a valuable tool to help clinicians to evaluate the risk of patients and make individual treatment strategies.

Disparities in the first-ever diagnosed liver cancers between the emergency department and outpatient department in Taiwan: a population-based study

BACKGROUND

Liver cancer is ranked fifth in incidence and second in mortality among cancers in Taiwan. Nevertheless, the Taiwan government does not screen for liver cancer in its free cancer screening and preventive health examination service. This study compared the differences in cancer stage and survival between patients who received an initial liver cancer diagnosis in outpatient departments (OPDs) and those who received such a diagnosis in emergency departments (EDs).

METHODS

This retrospective cohort study used the 2000-2016 National Health Insurance Database to obtain a sample from 2 million Taiwanese residents. To evaluate the effect of the utilization of the adult health examination offered to people aged ≥ 40 years, patients aged ≥ 40 years who received an initial liver cancer diagnosis between 2003 and 2015 were followed up until December 31, 2016.

RESULTS

In total, 2,881 patients were included in this study. A greater proportion of cancer cases in the OPD group were non-advanced than those in the ED group (75.26% vs. 54.23%). Having stage C or D cancer, having a low monthly salary, and a Charlson comorbidity index score ≥ 8, not having hepatitis B, being divorced, and attending a non-public hospital as the primary care institution were risk factors for initial ED diagnosis. The risk of liver cancer-specific death among the ED group patients was 1.38 times that among the OPD group patients (adjusted hazard ratio = 1.38, 95% confidence interval [CI] = 1.14-1.68, P < 0.001). However, the use of health examination did not exert a significant effect on the likelihood of liver cancer diagnosis in an ED (adjusted odds ratio = 0.86, 95% CI = 0.61-1.21, P = 0.381).

CONCLUSION

Government-subsidized health examinations are insufficient to prevent first-ever diagnosed liver cancers in EDs. Patients with liver cancers diagnosed in EDs had a higher risk of advanced stage and mortality. For early detection and treatment, the government may consider implementing liver cancer screening for high-risk and low-socioeconomic people.

Non-cancer-specific survival in patients with primary central nervous system lymphoma: A multi-center cohort study

Objective

The study aimed to evaluate the non-cancer-specific death risk and identify the risk factors affecting the non-cancer-specific survival (NCSS) in patients with primary central nervous system lymphoma (PCNSL).

Methods

This multi-center cohort study included 2497 patients with PCNSL in the Surveillance, Epidemiology and End Results (SEER) database from 2007 to 2016, with a mean follow-up of 4.54 years. The non-cancer-specific death risk in patients with PCNSL and primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) was evaluated using the proportion of deaths, standardized mortality ratio (SMR), and absolute excess risk (AER). Univariate and multivariate competing risk regression models were utilized to identify the risk factors of NCSS.

Results

PCNSL was the most frequent cause of death in PCNSL patients (75.03%). Non-cancer-specific causes constituted a non-negligible portion of death (20.61%). Compared with the general population, PCNSL patients had higher risks of death from cardiovascular disease (CVD) (SMR, 2.55; AER, 77.29), Alzheimer's disease (SMR, 2.71; AER, 8.79), respiratory disease (SMR, 2.12; AER, 15.63), and other non-cancer-specific diseases (SMR, 4.12; AER, 83.12). Male sex, Black race, earlier year of diagnosis (2007-2011), being unmarried, and a lack of chemotherapy were risk factors for NCSS in patients with PCNSL and PCNS-DLBCL (all P < 0.05).

Conclusion

Non-cancer-specific causes were important competing causes of death in PCNSL patients. More attention is recommended to non-cancer-specific causes of death in the management of PCNSL patients.

Prospective Predictors of Blood Pressure Among African American Men Living with HIV

Little is known about the predictors of blood pressure (BP) among African American men living with HIV. We examined whether age and body mass index (BMI) are associated with higher blood pressure (BP) and whether being married and muscular endurance are associated with lower BP among African American men living with HIV. Second, we examined whether being married moderated the effects of the other predictors on BP. Finally, we examined whether BMI mediated the relationship between muscular endurance and BP. This article is a prospective secondary analysis of data from a randomized controlled trial of a health-promotion intervention for African American men living with HIV. We measured the participants' BP pre-intervention and three, six, and 12 months post-intervention. Generalized estimating equations linear regression analyses examined whether marital status, age, BMI, and muscular endurance predicted BP post-intervention, adjusting for pre-intervention BP and the intervention. Older age, higher BMI, and lower muscular endurance predicted higher BP post-intervention, adjusting for the intervention and baseline BP. Although marital status did not predict post-intervention BP, it moderated the negative effect of higher BMI. The positive relation of BMI to BP was weaker among married men than unmarried men. Muscular endurance had an indirect impact on BP mediated through BMI. Public health efforts targeting older African American men with HIV should focus on increasing muscular endurance in this population to lower BMI as a strategy to reduce cardiovascular disease risk in this population.

Caregiving Strain, family functioning, and effort to change diet for patients with gastrointestinal cancer: A cross-sectional descriptive study

PURPOSE

Among patients with cancer, it has been found that the family system influences health-related behaviors and may promote a healthy diet. This study assessed the associations among cancer patients between family caregiver strain, family functioning, and efforts to change diet.

METHODS

This cross-sectional descriptive study was conducted in gastrointestinal outpatient units at two tertiary university hospitals in South Korea. This study included 401 main family caregivers of patients with gastrointestinal cancer. The caregivers were evaluated using structured, face-to-face questionnaires measuring family strain, family functioning, and effort to change diet.

RESULTS

Greater effort to change diet was associated with higher family functioning, having a spouse, and more caregiving time per week. Less effort to change diet was associated with greater levels of caregiving strain and with a son providing caregiving.

CONCLUSION

The efforts of family caregivers to alter diet are influenced by family strain and family functioning, as well as family caregivers' characteristics, such as marital status, health problems due to caregiving, care time and duration, and relationship with the patient. This study suggested that reducing family strain and improving family functioning in clinical settings facilitate the success to change dietary strategies for cancer families.

Distress, Depression, and the Effect of ZIP Code in Pancreaticobiliary Cancer Patients and Their Significant Others

BACKGROUND

Distress screening of cancer patients is mandated by the American College of Surgeons Commission on Cancer. Clinical implementation remains limited, particularly in surgical oncology settings in individuals with pancreaticobiliary cancers.

STUDY DESIGN

This study evaluated differences in mean distress scores based on the National Comprehensive Cancer Network Distress Thermometer & Problem List for patients with pancreaticobiliary cancers, benign pancreatic conditions, and for their significant others (SOs). The distress screening was conducted at the first office visit and postoperatively in a subset of those who had surgery. Distress Thermometer (DT) scores were dichotomized at ≤5 vs >5 and at ≥7 and correlated with Problem List items. The US ZIP Code database was used to correlate income range, percent poverty, and unemployment in the patient's self-identified ZIP code. Regression models were fitted to identify independent predictors of distress.

RESULTS

A total of 547 patients and 184 SOs were evaluated. Thirty percent of patients had DT scores >5, with pancreatic adenocarcinoma patients reporting the highest levels of distress. SOs of pancreatic adenocarcinoma patients reported even greater distress than the patients themselves. As the number of pre-existing medical problems increased; so did DT scores. Distress correlated with physical and emotional problems and worry about insurance coverage and transportation. Higher income level predicted higher DT scores, although poverty predicted lower DT scores. Depression was present in 12% of the patients. Distress improved in those undergoing surgery.

CONCLUSIONS

Distress and depression in pancreaticobiliary cancer patients and SOs are prevalent. The findings of this study have multiple actionable implications and require diagnosis, treatment, and referral to supportive care resources.

Timely Curative Treatment and Overall Mortality Among Veterans With Stage I NSCLC

Introduction

Early stage lung cancer (LC) outcomes depend on the receipt of timely therapy. We aimed to determine the proportions of Veterans with stage I NSCLC in the age group eligible for LC screening (LCS) receiving timely curative treatment (≤12 wk after diagnosis), the factors associated with timely treatment and modality, and the factors associated with overall mortality.

Methods

Retrospective cohort study in Veterans aged 55 to 80 years when diagnosed with stage I NSCLC during 2011 to 2015. We used multivariate logistic regression models to determine factors associated with receiving timely therapy and receiving surgery versus stereotactic body radiation therapy (SBRT). We used multivariate Cox proportional hazards regression analysis to determine factors associated with overall mortality.

Results

We identified 4796 Veterans with stage I NSCLC; the cohort was predominantly older, White males, current or former smokers, and living in urban areas. Overall, 84% underwent surgery and 16% underwent SBRT. The median time to treatment was 63 days (61 d for surgery; 71 d for SBRT), with 30% treated more than 12 weeks. Unmarried Veterans with higher social deprivation index were less likely to receive timely therapy. Black race, female sex, and never smoking were associated with lower overall mortality. Older Veterans receiving treatment >12 wk, with higher comorbidity index, and squamous cell carcinoma had higher overall mortality.

Conclusions

A total of 30% of the Veterans with stage I NSCLC in the age group eligible for LCS received curative treatment more than 12 weeks after diagnosis, which was associated with higher overall mortality. Delays in LC treatment could decrease the mortality benefits of LCS among the Veterans.

A nomogram for predicting cancer-specific survival and overall survival in elderly patients with nonmetastatic renal cell carcinoma

Background

Renal cell carcinoma (RCC) is a common malignant tumor in the elderly, with an increasing trend in recent years. We aimed to construct a nomogram of cancer-specific survival (CSS) and overall survival (OS) in elderly patients with nonmetastatic renal cell carcinoma (nmRCC).

Methods

Clinicopathological information was downloaded from the Surveillance, Epidemiology, and End Results (SEER) program in elderly patients with nmRCC from 2010 to 2015. All patients were randomly assigned to a training cohort (70%) or a validation cohort (30%). Univariate and multivariate Cox regression analyses were used to identify independent risk factors for patient outcomes in the training cohort. A nomogram was constructed based on these independent risk factors to predict the 1-, 3-, and 5-year CSS and OS in elderly patients with nmRCC. We used a range of methods to validate the accuracy and reliability of the model, including the calibration curve, consistency index (C-index), and the area under the receiver operating curve (AUC). Decision curve analysis (DCA) was used to test the clinical utility of the model.

Results

A total of 12,116 patients were enrolled in the study. Patients were randomly assigned to the training cohort (N = 8,514) and validation cohort (N = 3,602). In the training cohort, univariate and multivariate Cox regression analysis showed that age, marriage, tumor histological type, histological tumor grade, TN stage, tumor size, and surgery are independent risk factors for prognosis. A nomogram was constructed based on independent risk factors to predict CSS and OS at 1-, 3-, and 5- years in elderly patients with nmRCC. The C-index of the training and validation cohorts in CSS were 0.826 and 0.831; in OS, they were 0.733 and 0.734, respectively. The AUC results of the training and validation cohort were similar to the C-index. The calibration curve indicated that the observed value is highly consistent with the predicted value, meaning the model has good accuracy. DCA results suggest that the clinical significance of the nomogram is better than that of traditional TNM staging.

Conclusions

We built a nomogram prediction model to predict the 1-, 3- and 5-year CSS and OS of elderly nmRCC patients. This model has good accuracy and discrimination and can help doctors and patients make clinical decisions and active monitoring.

Risk of Psychiatric Disorders Among Spouses of Patients With Cancer in Denmark and Sweden

IMPORTANCE

There is emerging evidence that spouses of patients with cancer may have a higher prevalence of mental illness, but these studies have been limited by pre-post designs, focus on a single mental illness, and short follow-up periods.

OBJECTIVES

To assess the overall burden of psychiatric disorders among spouses of patients with cancer vs spouses of individuals without cancer and to describe possible changes in this burden over time.

DESIGN, SETTING, AND PARTICIPANTS

This population based cohort study included spouses of patients with cancer (diagnosed 1986-2016 in Denmark and 1973-2014 in Sweden; exposed group) and spouses of individuals without cancer (unexposed group). Members of the unexposed group were individually matched to individuals in the exposed group on the year of birth, sex, and country. Spouses with and without preexisting psychiatric morbidity were analyzed separately. Data analysis was performed between May 2021 and January 2022.

EXPOSURES

Being spouse to a patient with cancer.

MAIN OUTCOMES AND MEASURES

The main outcome was a clinical diagnosis of psychiatric disorders through hospital-based inpatient or outpatient care. Flexible parametric models and Cox models were fitted to estimate hazard ratios (HRs) with 95% CIs, adjusted for sex, age and year at cohort entry, country, household income, and cancer history.

RESULTS

Among 546 321 spouses in the exposed group and 2 731 574 in the unexposed group who had no preexisting psychiatry morbidity, 46.0% were male participants, with a median (IQR) age at cohort entry of 60 (51-68) years. During follow-up (median, 8.4 vs 7.6 years), the incidence rate of first-onset psychiatric disorders was 6.8 and 5.9 per 1000 person-years for the exposed and unexposed groups, respectively (37 830 spouses of patients with cancer [6.9%]; 153 607 of spouses of individuals without cancer [5.6%]). Risk of first-onset psychiatric disorders increased by 30% (adjusted HR, 1.30; 95% CI, 1.25-1.34) during the first year after cancer diagnosis, especially for depression (adjusted HR, 1.38; 95% CI, 1.30-1.47) and stress-related disorders (adjusted HR, 2.04; 95% CI, 1.88-2.22). Risk of first-onset psychiatric disorders increased by 14% (adjusted HR, 1.14; 95% CI, 1.13-1.16) during the entire follow-up, which was similar for substance abuse, depression, and stress-related disorders. The risk increase was more prominent among spouses of patients diagnosed with a cancer with poor prognosis (eg, pancreatic cancer: adjusted HR, 1.41; 95% CI, 1.32-1.51) or at an advanced stage (adjusted HR, 1.31; 95% CI, 1.26-1.36) and when the patient died during follow-up (adjusted HR, 1.29; 95% CI, 1.27-1.31). Among spouses with preexisting psychiatric morbidity, the risk of psychiatric disorders (first-onset or recurrent) increased by 23% during the entire follow-up (adjusted HR, 1.23; 95% CI, 1.20-1.25).

CONCLUSIONS AND RELEVANCE

In this cohort study of 2 populations in Denmark and Sweden, spouses of patients with cancer experienced increased risk of several psychiatric disorders that required hospital-based specialist care. Our results support the need for clinical awareness to prevent potential mental illness among the spouses of patients with cancer.

Marital status and survival in cancer patients: A systematic review and meta-analysis

BACKGROUND

In recent years, authors have repeatedly reported on the significance of social support in cancer survival. Although overall the studies appear to be convincing, little is known about which types of social support promote better survival rates, and which subgroups of cancer patients are more susceptible to the benefits of it. The aim of this study was to identify, organize, and examine studies reporting on the significance of social support in cancer survival.

METHODS

The PubMed, CINAHL and EBSCO databases were searched using the keywords social support/marital status, cancer, and survival/mortality. Where possible we used a meta-analytical approach, specifically a random effect model, in order to combine the results of the hazard ratios in studies from which this information could be obtained. When interpreting clinical relevance, we used the number needed to treat (NNT).

RESULTS

Better survival was observed in married patients when compared to unmarried (single, never-married, divorced/separated, and widowed) in overall and cancer-specific survival. Gender group differences showed that the association was statistically significant only in cancer-specific survival when comparing divorced/separated male and female cancer patients (p < 0.001), thus confirming results from the previous meta-analysis.

CONCLUSIONS

Being unmarried is associated with significantly worse overall and cancer-specific survival. The most vulnerable group found in our study were divorced/separated men. The results of this review can motivate physicians, oncologists, and other healthcare professionals to be aware of the importance of patients' social support, especially in the identified sub-group.

Influence of Sociodemographic Determinants on the Hodgkin Lymphoma Baseline Characteristics in Long Survivors Patients Enrolled in the Prospective Phase 3 Trial AHL2011

INTRODUCTION

Whereas numerous studies on several cancers describe the link between social conditions and disease severity, little is known about the social and demographic characteristics of Hodgkin lymphoma (HL) patients. At diagnosis, 10-15% of the patients in the advanced stages have a well-known poor outcome owing to their chemoresistance, but the determinants of the more advanced stages remain elusive. The objective of the present study was to decipher the potential impact of social disparities on the disease features at diagnosis and analyze how the sociodemographic patient features could impact the HL outcome of patients with advanced-stage HL enrolled in the AHL2011 trial.

METHODS

This ancillary study was conducted on a cohort of patients from French centers that had recruited more than five patients in the phase III AHL2011 study (NCT0135874). Patients had to be alive at the time of the ancillary study and had to have given their consent to answer the questionnaire. Pre-treatment data (age, gender, stage, B symptoms, IPS), the treatment received, the responses to PET-CT, and the presence of serious adverse events (serious adverse events-SAEs) were all extracted from the AHL2011 trial database. Sociodemographic data-marital status, living area, level of education, socio-professional category, and professional situation-were extracted from the questionnaires. The population density at the point of diagnosis was determined based on ZIP Code, and the distance from the reference medical center was then calculated by the road network. Baseline PET acquisition was performed before any treatment. PET images at baseline were centrally reviewed. The total metabolic tumor volume (TMTV) at the baseline was calculated using a 41% SUVmax cutoff for each lesion. Progression-free survival was defined as the time from randomization to the first progression, relapse, or death from any cause or the last follow-up. The data cutoff for the analyses presented here was 31 October 2017. The progression-free survival was analyzed on an intention-to-treat basis.

RESULTS

Among the 823 patients enrolled in the AHL2011 study, the questionnaire was sent to 394 patients, of whom 232 (58.9%) responded. At the time of HL diagnosis, 61.9% (N = 143) of patients declared that they were not socially isolated, 38.1% (N = 88) that they were single, 163 (71.2%) had a professional activity, and 66 (28.8%) were inactive owing to unemployment, retirement, or sick leave. Of the patients, 31.1% (N = 71) lived in a rural region, compared to 68.9% (N = 157) that lived in an urban region. The residence ZIP Code at the time of HL diagnosis was available for 163 (70%). Sociodemographic characteristics did not influence the presence of usual prognostic factors (ECOG, B symptoms, bulky mass, IPS) except for professional activity, which was associated with more frequent low IPS (0-2) (79 (48.5%) active versus 20 (30.3%) inactive patients; p = 0.012). Likewise, no correlation was observed between TMTV and sociodemographic characteristics. However, the TMTV quartile distribution was different according to the living area, with the two upper quartiles being enriched with patients living in a rural area (p = 0.008). Moreover, a negative correlation between the average number of the living area's inhabitants and TMTV (R Pearson = -0.29, p = 0.0004) was observed.

CONCLUSION

This study focused on sociodemographic parameters in advanced-stage HL patients and shows that professional activity is associated with more favorable disease features (low IPS), while patients living in rural or low-populated areas are more likely to have an unfavorable HL presentation with a high tumor burden (high TMTV). These data suggest that some patient sociodemographic characteristics might impact either access to medical care or environmental exposure, leading to a higher frequency of unfavorable presentations. Further prospective sociodemographic studies are necessary to confirm these preliminary results.

Development and Validation of a Prognostic Nomogram for Lung Adenocarcinoma: A Population-Based Study

PURPOSE

To establish an effective and accurate prognostic nomogram for lung adenocarcinoma (LUAD). Patients and Methods. 62,355 LUAD patients from 1975 to 2016 enrolled in the Surveillance, Epidemiology, and End Results (SEER) database were randomly and equally divided into the training cohort (n = 31,179) and the validation cohort (n = 31,176). Univariate and multivariate Cox regression analyses screened the predictive effects of each variable on survival. The concordance index (C-index), calibration curves, receiver operating characteristic (ROC) curve, and area under the ROC curve (AUC) were used to examine and validate the predictive accuracy of the nomogram. Kaplan-Meier curves were used to estimate overall survival (OS).

RESULTS

10 prognostic factors associated with OS were identified, including age, sex, race, marital status, American Joint Committee on Cancer (AJCC) TNM stage, tumor size, grade, and primary site. A nomogram was established based on these results. C-indexes of the nomogram model reached 0.777 (95% confidence interval (CI), 0.773 to 0.781) and 0.779 (95% CI, 0.775 to 0.783) in the training and validation cohorts, respectively. The calibration curves were well-fitted for both cohorts. The AUC for the 3- and 5-year OS presented great prognostic accuracy in the training cohort (AUC = 0.832 and 0.827, respectively) and validation cohort (AUC = 0.835 and 0.828, respectively). The Kaplan-Meier curves presented significant differences in OS among the groups.

CONCLUSION

The nomogram allows accurate and comprehensive prognostic prediction for patients with LUAD.

Divorce after breast cancer diagnosis and its impact on quality of life

OBJECTIVE

This study aims to identify factors associated with divorce following breast cancer diagnosis and measures the impact of divorce on the quality of life (QoL) of patients.

METHODS

We used cross-sectional survey data collected at breast cancer outpatient clinics in South Korea from November 2018 to April 2019. Adult breast cancer survivors who completed active treatment without any cancer recurrence at the time of the survey (N = 4,366) were included. The participants were classified into two groups: "maintaining marriage" and "being divorced," between at the survey and at the cancer diagnosis. We performed logistic regression and linear regression to identify the factors associated with divorce after cancer diagnosis and to compare the QoL of divorced and nondivorced survivors.

RESULTS

Approximately 11.1/1,000 of married breast cancer survivors experienced divorce after cancer diagnosis. Younger age, lower education, and being employed at diagnosis were associated with divorce. Being divorced survivors had significantly lower QoL (Coefficient [Coef] = -7.50; 95% CI = -13.63, -1.36), social functioning (Coef = -9.47; 95% CI = -16.36, -2.57), and body image (Coef = -8.34; 95% CI = -6.29, -0.39) than survivors who remained married. They also experienced more symptoms including pain, insomnia, financial difficulties, and distress due to hair loss.

CONCLUSION

Identifying risk factors of divorce will ultimately help ascertain the resources necessary for early intervention.

Changes in the survival of adult patients with metastasized melanoma with the approval of immune checkpoint inhibitors: A retrospective study from the United States database

BACKGROUND

Immune-checkpoint inhibitors (ICI) have revolutionized the treatment of metastatic melanoma. Ipilimumab and Ipilimumab-Nivolumab combination therapies were approved by the United States Food and Drug Administration in 2011 and 2015, respectively. We aimed to evaluate potential changes in the survival of patients with metastatic melanoma following the approval of these agents.

METHODS

We extracted data from the Surveillance, Epidemiology, and End Results (SEER) database (Nov 2021 submission). All patients aged 20 and above who were diagnosed with 'distant' melanoma (per 'combined summary stage') from 2007 through 2018 were included in the study. This time period was further sub-categorized into 2007-2010 (pre-ICI era), 2011-2014 (single-agent ICI era), and 2015-2018 (combination ICI era) based on the approval timeline of ICI.

RESULTS

The median overall survival (OS) was 8, 10, and 14 months in the pre-ICI, single-agent ICI, and combination ICI eras respectively (log-rank test, χ² = 189.03, p < 0.001). On Cox-proportional hazard analysis, patients diagnosed in the single-agent and combination ICI eras had a significantly lower risk of dying [HR 0.82 (95% CI 0.78-0.87) and 0.67 (0.64-0.71), respectively] compared to patients diagnosed in the pre-ICI era. Patients who were of the male gender, aged ≥ 65 years, and those receiving chemotherapy and/or radiotherapy were at a significantly higher risk of dying. Married individuals had a significantly lower risk of dying compared to patients who were divorced, separated, or widowed at the time of diagnosis. There was no significant difference in survival demonstrated among non-Hispanic blacks versus non-Hispanic whites.

CONCLUSION

Survival of patients with metastatic melanoma has improved in the era of immune checkpoint inhibitors. It implies that the survival of patients reported in trials can be correlated at a population level as well. Future analysis from the SEER database is needed when new data becomes available to see if there is a further increase in OS.
