Risk of breast cancer-related death in women with a prior cancer

Analysis of Risk Factors for Secondary Endometrial Cancer-Related Death: A SEER-Based Study

Purpose

The aim of this study was to analyze the survival of patients with endometrial cancer diagnosed after a prior cancer and identify risk factors of endometrial cancer death in this population.

Methods

Totally 1371 women diagnosed with second primary endometrial cancer (SPEC) between 2004 and 2015 were identified using the SEER database. Clinicopathological characteristics were collected, and Fine and Gray regression model was employed to assess the impact of treatment for the first primary cancer (FPC) and SPEC on the mortality of endometrial cancer patients. After propensity score matching (PSM), patients diagnosed with single primary endometrial cancer and SPEC between 2004 and 2015 were included as the second cohort. Kaplan-Meier and Cox survival risk models were used to assess the influence of previous cancer history on survival.

Results

Patients previously diagnosed as lung cancer exhibited the lowest overall survival (OS). A diagnostic interval of ≥3 years was significantly associated with higher mortality from SPEC compared with that <3 years. Surgical treatment for SPEC was linked to a reduced risk of endometrial cancer-specific mortality (ECSM) and non-ECSM. Conversely, radiotherapy and chemotherapy were associated with an increased risk of ECSM. The 1-, 3-, and 5-year OS rates of patients with SPEC were significantly lower than those with single primary endometrial cancer whether before or after PSM. Univariate and multivariate analyses further demonstrated that endometrial cancer, either as FPC or SPEC, was independently associated with an increased risk for endometrial cancer-specific survival (ECSS) and OS.

Conclusion

Chemotherapy and radiotherapy for SPEC can elevate the risk of ECSM. Whether as FPC or SPEC, endometrial cancer is demonstrated to be a significant independent risk factor for ECSS and OS.

Age-related Disparities in Pan-Cancer Mortality and Causes of Death: Analysis of Surveillance, Epidemiology, and End Results (SEER) Data

Comprehensive analysis of mortality and causes of death (COD) in cancers was of importance to conduct intervention strategies. The current study aimed to investigate the mortality rate and COD among cancers, and to explore the disparities between age. Initially, cancer patients diagnosed between 2010 and 2019 from the surveillance, epidemiology, and end results (SEER) database were extracted. Then, frequencies and percentage of deaths, and mortality rate in different age groups were calculated. Meanwhile, age distribution of different COD across tumor types was illustrated while the standardized mortality ratios (SMR) stratified by age were calculated and visualized. A total of 2,670,403 death records were included and digestive system cancer (688,953 death cases) was the most common primary cancer type. The mortality rate increased by 5.6% annually in total death, 4.0% in cancer-specific death and 10.9% in non-cancer cause. As for cancer-specific death, the age distribution varied among different primary tumor types due to prone age and prognosis of cancer. The top five non-cancer causes in patients older than 50 were cardiovascular and cerebrovascular disease, other causes, COPD and associated conditions, diabetes as well as Alzheimer. The SMRs of these causes were higher among younger patients and gradually dropped in older age groups. Mortality and COD of cancer patients were heterogeneous in age group due to primary tumor types, prone age and prognosis of cancer. Our study conducted that non-cancer COD was a critical part in clinical practice as well as cancer-specific death. Individualized treatment and clinical intervention should be made after fully considering of the risk factor for death in different diagnosis ages and tumor types.

Review of the relationship between tumor receptor subtypes and preference for visceral and/or serosal metastasis in breast cancer patients

In this study, we investigated the molecular phenotype-cancer relationship that may favor the main metastatic tendencies of cancer by comparing the association of receptor subtypes with the presence of metastasis, serosal metastasis, and/or visceral metastases in patients diagnosed with breast cancer. In this study, we retrospectively evaluated 853 patients who were diagnosed with breast cancer and followed up at our hospital between 2017 and 2022. The probability of metastasis in the most common tumor group, the non-special type of invasive carcinoma was significantly higher than that in other tumor groups. We formed our groups according to estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki67 status. In addition, when we compared the receptor groups, no significant difference was found between the receptor groups (Table 1). When the entire breast cancer cohort was considered, the association of serosal metastasis was statistically significantly higher in the ER and/or PR (+) and, HER2 (-) receptor subgroup than in all other receptor groups (P < .006), and the association of visceral metastasis/visceral + serosal metastasis with the ER and/or PR (+) and, HER2 (-) receptor subgroup was significantly higher than that in all other receptor groups (P < .001) (Table 2). In this study, we aimed to investigate the possible relationship between molecular markers of the primary tumor and the preference for serosal and visceral metastases over distant metastases in a large cohort of patients to contribute to the improvement of the diagnosis and treatment of breast cancer, a heterogeneous disease group. To the best of our knowledge, our study is the first to statistically investigate the association between receptor subgroups and visceral, serosal, and serosal + visceral metastases as a group and to reach some conclusions.

Understanding cancer genetic risk assessment motivations in a remote tailored risk communication and navigation intervention randomized controlled trial

Background

National guidelines recommend cancer genetic risk assessment (CGRA) (i.e. genetic counseling prior to genetic testing) for women at increased risk for hereditary breast and ovarian cancer (HBOC). Less than one-half of eligible women obtain CGRA, leaving thousands of women and their family members without access to potentially life-saving cancer prevention interventions.

Purpose

The Genetic Risk Assessment for Cancer Education and Empowerment Project (GRACE) addressed this translational gap, testing the efficacy of a tailored counseling and navigation (TCN) intervention vs. a targeted print brochure vs. usual care on CGRA intentions. Selected behavioral variables were theorized to mediate CGRA intentions.

Methods

Breast and ovarian cancer survivors meeting criteria for guideline-based CGRA were recruited from three state cancer registries (N = 654), completed a baseline survey, and were randomized. TCN and targeted print arms received the brochure; TCN also participated in a tailored, telephone-based decision coaching and navigation session grounded in the Extended Parallel Process Model and Ottawa Decision Support Framework. Participants completed a one-month assessment. Logistic regression was used to compare the rate of CGRA intentions. CGRA intentions and theorized mediator scores (continuous level variables) were calculated using mixed model analysis.

Results

CGRA intentions increased for TCN (53.2%) vs. targeted print (26.7%) (OR = 3.129; 95% CI: 2.028, 4.827, p < .0001) and TCN vs. usual care (23.1%) (OR = 3.778, CI: 2.422, 5.894, p < .0001). Perceived risk (p = 0.023) and self-efficacy (p = 0.035) mediated CGRA intentions in TCN.

Conclusions

Improvements in CGRA intentions and theorized mediators support the use of a tailored communication intervention among women at increased HBOC risk. (Clinicaltrials.gov: NCT03326713.)Trial registration: ClinicalTrials.gov identifier: NCT03326713.

Impact of prior cancer history on survival of patients with hypopharyngeal cancer

BACKGROUND

The impact of prior cancer history on survival of hypopharyngeal cancer patients remains unknown. The present study assessed the impact of prior cancer history on survival of patients with hypopharyngeal cancer.

METHODS

Patients with primary hypopharyngeal cancer diagnosed between 2004 and 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was conducted to balance baseline characteristics. One-to-one PSM, Kaplan-Meier method, and log-rank test were performed for survival analysis.

RESULTS

We included 5017 patients with hypopharyngeal cancer. Prior cancer history had no significant impact on overall survival of hypopharyngeal cancer patients in comparison with those without prior cancer history (p = 0.845, after PSM). Subgroup analysis showed that prior cancer history had no significant effect on overall survival of hypopharyngeal cancer patients.

CONCLUSION

More hypopharyngeal cancer patients with prior cancer history should be considered for clinical trials. However, further prospective studies are needed.

Impact of a previous cancer history on the overall survival of patients with primary gastric cancer: A SEER population-based study

BACKGROUND

The impact of previous cancers on the survival of gastric cancer (GC) patients is still uncertain. To evaluate the impact of a prior cancer history on the overall survival of patients with primary GC.

METHODS

The Surveillance, Epidemiology, and End Results (SEER) database provided data on patients diagnosed with GC as the first or second primary malignancy between 2010 and 2015 in this retrospective cohort study. Cox proportional hazards models, Kaplan-Meier curves and forest plots were utilized to analyze overall survival. Subgroup analysis was performed based on age, gender, race and prior cancer type.

RESULTS

Totally 39,379 were eligible for this study, including 7403 (18.8%) with a previous cancer history. A previous cancer was an independent risk factor for overall survival [hazard ratio (HR) = 1.103, 95% confidence interval (CI): 1.070-1.138]. For GC patients aged 40-60 years (HR = 1.191, 95% CI: 1.084-1.308) and ≥60 years (HR = 1.093, 95% CI: 1.058-1.13) at diagnosis, a previous cancer was significantly associated with worse overall survival. GC patients with previous oral cavity and pharynx cancer (HR = 1.249, 95% CI: 1.038-1.501), respiratory system cancer (HR = 1.177, 95% CI: 1.076-1.286), female genital system cancer (HR = 1.169, 95% CI: 1.011-1.351), or lymphoma cancer (HR = 1.192, 95% CI: 1.023-1.389) had shorter overall survival than GC patients without a previous cancer.

CONCLUSION

A previous cancer adversely affected the overall survival of GC patients. Specifically, GC patients aged ≥40 years, or with oral cavity and pharynx cancer, respiratory system cancer, female genital system cancer, or lymphoma cancer had inferior overall survival. These patients should obtain more attention and get individualized treatment to improve prognosis, and clinical trial eligibility criteria could be reconsidered for particular age and cancer types.

Survival of women diagnosed with breast cancer and who have survived a previous cancer

PURPOSE

Many women diagnosed with breast cancer have survived previous cancer; yet little is known about the impact of previous cancer on overall and cancer-specific survival.

METHODS

This population-based cohort study using SEER-Medicare data included women (age ≥ 66 years) diagnosed with breast cancer between 2005 and 2015. Separately by breast cancer stage, we estimated effect of previous cancer on overall survival using Cox regression and on cause-specific survival using competing risk regression; all survival analyses adjusted for covariates.

RESULTS

Of 138,576 women diagnosed with breast cancer, 8% had a previous cancer of another organ site, most commonly colorectal or uterine cancer or melanoma. Many of these women (46.3%) were diagnosed within 5 years of breast cancer. For all breast cancer stages except IV wherein there was no difference, women with vs. without previous cancer had worse overall survival. This survival disadvantage was driven by deaths due to the previous cancer and other causes. In contrast, women with previous cancer generally had favorable breast-cancer-specific survival, although this varied by stage. Overall survival varied by previous cancer type, timing, and stage; previous lung cancer, cancer diagnosed within 1 year of incident breast cancer, and previous cancer at a distant stage were associated with the worst survival. In contrast, women with a previous melanoma had equivalent overall survival to women without previous cancer.

CONCLUSION

We observed variable impact of previous cancer on overall and breast-cancer-specific survival depending on breast cancer stage at diagnosis and the type, timing, and stage of previous cancer.

Emerging landscape of circHIPK3 and its role in cancer and other diseases (Review)

Circular RNAs (circRNAs) are a special class of recently re‑discovered RNAs, which are covalently closed ring RNA molecules. circRNAs have been reported to possess multiple functions and are considered crucial regulators of several processes, and are therefore gaining increasing attention. In recent years, increasing evidence has shown that circRNAs are implicated in several crucial biological processes via regulation of gene expression, and their dysregulation is also associated with the development of numerous diseases, particularly acting as oncogenic or tumor‑suppressor molecules in cancer. Furthermore, circRNAs are involved in cell proliferation, differentiation, apoptosis, invasion and metastasis. In the present review, the biogenesis and functions of circRNAs are described, with a focus on the most recent research advances and the emerging roles of circular homeodomain‑interacting protein kinase 3 (circHIPK3) in human diseases. The present review may provide novel avenues for research on the roles of circHIPK3 as a clinical diagnostic and prognostic biomarker, as well as highlighting promising therapeutic targets for certain diseases and cancer.

First clinical experience with CDK4/6 inhibitors in breast cancer therapy

For hormone receptor-positive, HER2-negative breast cancer patients with metastatic or advanced disease, therapy with CDK4/6 inhibitors in addition to aromatase inhibitors (AIs) or to the estrogen receptor (ER) downregulator fulvestrant has resulted in an additional therapy option and a longer progression-free survival. In the Gynecologic-Oncology Clinic, Diakonie-Klinikum Schwäbisch Hall, we followed and registered our initial clinical experience with CDK4/6 inhibitors, following the side effects and tumor response over two years since they were officially approved for general use in Germany. Differences were observed when palbociclib or ribociclib was used in combination with letrozole or anastrozole or fulvestrant. The dynamic side effects and tumor response under therapy with palbociclib or ribociclib were found to be comparable with the main reported data in the official drug information. The CDK4/6 inhibitors have an important and promising role in the therapy of breast cancer patients. Patient age and therapy duration do not influence the use of palbociclib or ribociclib, although it may be important which AI is used in combination with palbociclib.

Survival outcomes in esophageal cancer patients with a prior cancer

To achieve a deeper understanding of patients who developed esophageal cancer (EC) as a second primary malignancy, which may help guide in clinical practice for these patients in the future.In the primary cohort, EC patients with a prior malignancy were identified from the surveillance, epidemiology, and end result 18 database. The 5 most common types of prior cancers were picked out based on the frequency of occurrence. In addition, Kaplan-Meier and log-rank tests were performed to investigate the survival impacts of prior cancers on EC patients. Besides, a competing-risk model was constructed to explore the relationship between EC-treatment and EC-specific mortality. In the secondary cohort, patients with stage I-III (N0M0) EC from 2004 to 2014 were enrolled. After propensity score matching, univariate and multivariate Cox analyses were developed to determine the prognostic factors for EC patients.A total of 1199 EC patients with a prior cancer were identified in the primary cohort. The 5 most common sites of prior cancers were prostate, female breast, bladder, lung and bronchus, and larynx. Kaplan-Meier analyses revealed that EC patients with prior prostate cancer and bladder cancer had the best overall survival (OS), while those with prior cancers of larynx and lung and bronchus had the worst OS. Fine and Gray competing risks analysis indicated that the administration of surgery was closely associated with better EC-specific survival (P < .001). In the secondary cohort, multivariate Cox analyses found that age at diagnosis, race, tumor grade, tumor extent, nodal status and metastasis stage, histology, and the administration of surgery were prognostic factors for OS and cancer-specific survival in EC patients. Besides, the existence of a prior cancer was an independent prognostic factor for cancer-specific survival.EC remains to be the most important cause of death in EC patients with a prior cancer. EC related treatment should be actively adopted in patients with a prior cancer, as they were more likely to die from EC than the prior cancer. EC patients with a prior cancer had comparable OS than those without.

Effect of prior cancer on survival outcomes for patients with advanced prostate cancer

BACKGROUND

A history of prior cancer commonly results in exclusion from cancer clinical trials. However, whether a prior cancer history has an adversely impact on clinical outcomes for patients with advanced prostate cancer (APC) remains largely unknown. We therefore aimed to investigate the impact of prior cancer history on these patients.

METHODS

We identified patients with advanced prostate cancer diagnosed from 2004 to 2010 in the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was used to balance baseline characteristics. Kaplan-Meier method and the Cox proportional hazard model were utilized for survival analysis.

RESULTS

A total of 19,772 eligible APC patients were included, of whom 887 (4.5 %) had a history of prior cancer. Urinary bladder (19 %), colon and cecum (16 %), melanoma of the skin (9 %) malignancies, and non-hodgkin lymphoma (9 %) were the most common types of prior cancer. Patients with a history of prior cancer had slightly inferior overall survival (OS) (AHR = 1.13; 95 % CI [1.02-1.26]; P = 0.017) as compared with that of patients without a prior cancer diagnosis. Subgroup analysis further indicated that a history of prior cancer didn't adversely impact patients' clinical outcomes, except in patients with a prior cancer diagnosed within 2 years, at advanced stage, or originating from specific sites, including bladder, colon and cecum, or lung and bronchus, or prior chronic lymphocytic leukemia.

CONCLUSIONS

A large proportion of APC patients with a prior cancer history had non-inferior survival to that of patients without a prior cancer diagnosis. These patients may be candidates for relevant cancer trials.

Impact of prior cancer history on survival of patients with gastric cancer

BACKGROUND

Patients with prior cancer history are commonly excluded from clinical trial. However, the impact of prior cancer on survival of patients with gastric cancer remains largely unknown. The aim of this study was to evaluate the prevalence of prior cancer and assess its impact on survival of patients diagnosed with gastric cancer.

METHODS

Patients with gastric cancer as the primary or second primary malignancies diagnosed from 2004 to 2010 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was conducted to balance baseline characteristics. Kaplan-Meier method, multivariate Cox proportional hazard model, and multivariate competing risk model were performed for survival analysis.

RESULTS

A total of 28,795 eligible patients with gastric cancer were included, of whom 2695 (9.35%) had a history of prior cancer. Prostate (35%), breast (12%), colon (8%), and urinary bladder (7%) malignancies were the most common prior cancer types. Patients with prior cancer history had slightly inferior overall survival (AHR = 1.06; 95% CI [1.00-1.12]; P = 0.043) but superior gastric cancer-specific survival (AHR = 0.82; 95% CI [0.76-0.88]; P < 0.001) compared with those without prior cancer. The subgroup analysis determined that a prior cancer history did not adversely affect gastric patients' clinical outcomes, except in those with prior cancer diagnosed within one year, at distant stage, or originating from lung and bronchus.

CONCLUSION

A substantial proportion of gastric cancer patients with a history of prior cancer had non-inferior clinical outcome to those without prior cancer. These patients should be considered in clinical trials.

Survival outcomes in prostate cancer patients with a prior cancer

Background

To shed light on the survival outcomes of prostate cancer (PCa) patients diagnosed after a prior cancer and identify prognostic factors for overall survival (OS) and cancer-specific survival (CSS) in PCa patients.

Methods

In the primary group, a total of 1,778 PCa patients with a prior cancer were identified in the Surveillance, Epidemiology, and End Results (SEER) database from 2005 to 2015, retrospectively. Baseline characteristics and causes of death (COD) of these patients were collected and compared. In the second group, a total of 10,296 PCa patients [5,148 patients with PCa as the only malignancy and 5,148 patients with PCa as their second primary malignancy (SPM)] diagnosed between 2010 and 2011 were extracted to investigate the impact of prior cancers on survival outcomes.

Results

In PCa patients with a prior cancer, the most common type of prior cancer was from gastrointestinal system (29.92%), followed by urinary system (21.37%). Patients were more likely to die of the prior caner, and those with prior cancer from respiratory system had the worst survival outcomes. Moreover, the overall ratios in patients with stage (PCa) I–II and III–IV diseases were 0.21 and 1.65, indicating that patients with higher stage diseases were more likely to die of PCa. In the second group, patients with PCa as the SPM had worse OS than those with PCa as the first primary cancer. Lastly, prognostic factors for OS and CSS in PCa patients were explored.

Conclusions

PCa remains to be an important COD for patients with a prior malignancy, especially for those with high-stage diseases. PCa patients with a prior cancer had worse survival outcomes than those without.

MiR-519d and miR-328-3p Combinatorially Suppress Breast Cancer Progression

Background

MiR-519d and miR-328-3p had tumor-regulatory properties in different cancers, but their combinatorial effects and potential common target in breast cancer had not been fully reported. This research targeted to study the underlying mechanism of how miR-519d and miR-328-3p cooperatively suppressed breast cancer.

Methods

MiR-519d and miR-328-3p expressions in breast cancer tissues and cells were assessed and Ki-67 expression was also checked. DLR assay was executed to verify whether Ki-67 was a common target of miR-519d and miR-328-3p. Western blot, flow cytometry, colony formation, wound healing and transwell assays were applied to examine the inhibitory roles of these two miRNAs on the malignant behaviors of breast cancer cells and the potential molecular mechanism.

Results

Impeded miR-519d and miR-328-3p expressions and enhanced Ki-67 expression were detected in breast cancer tissues and cells. Ki-67 was confirmed as a target of these two miRNAs. MiR-519d and miR-328-3p hampered cell proliferation and blocked cell cycle via binding to Ki-67 and they also suppressed migration and invasion. The combinatorial effects of two miRNAs were much stronger than a single miRNA.

Conclusion

Our findings proved that miR-519d and miR-328-3p played combinatorial anti-cancer roles in breast cancer by directly targeting a common target Ki-67. Our study suggested that these two miRNAs might own the potential to become novel therapeutic biomarkers involved in the diagnosis and therapy of breast cancer.

Impact of prior cancer history on the survival of patients with larynx cancer

BACKGROUND

Patients with a prior history of cancer are commonly excluded from clinical trial. Increasing number of studies implied that a prior cancer did not adversely affect the clinical outcome among various types of cancer patients. However, the impact of prior cancer on survival of larynx cancer patients remains largely unknown. The aim of this study was to evaluate the prevalence of prior cancer and assess its impact on survival of patients diagnosed with larynx cancer.

METHODS

Patients with larynx cancer as the first or second primary malignancy diagnosed from 2004 to 2015 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Propensity score matching (PSM) was conducted to balance baseline characteristics. Kaplan-Meier method, multivariate Cox proportional hazard model, and multivariate competing risk model were performed for survival analysis.

RESULTS

A total of 24,812 eligible patients with larynx cancer were included in the study, wherein a total of 2436 patients (9.8%) had a prior history of cancer. Prostate (36%), lung and bronchus (10%), urinary bladder (7%), and breast (6%) were the most common types of prior cancer. A prior cancer history served as a risk factor for overall survival (AHR =1.30; 95% CI [1.21-1.41]; P < 0.001) but a protective factor for cancer-specific mortality (AHR = 0.83; 95% CI [0.72-0.94]; P = 0.004) in comparison with those without prior cancer. The subgroup analysis showed that a prior history of cancer adversely affected overall survival of patients with larynx cancer in most subgroups stratified by timing and types of prior cancer, as well as by different clinicopathologic features.

CONCLUSION

Our study indicated an adverse survival impact of a prior history of cancer on patients with larynx cancer. Except for a few particular prior cancer, clinical trials should be considered prudently for laryngeal cancer patients with prior cancers.

Impact of Prior Cancer on the Prognosis of Patients With Laryngeal Cancer: A Population-Based Study Using the Surveillance, Epidemiology, and End Results Database

Background: Little is known about the clinical significance of laryngeal cancer as a subsequent tumor. We aimed to determine the impact of a prior cancer history on the prevalence and prognosis of patients with laryngeal cancer. Methods: We retrospectively reviewed patients diagnosed with laryngeal cancer between 2004 and 2011 in the Surveillance, Epidemiology, and End Results (SEER) database. The t-test and chi-squared test were used to compare variables as appropriate. Matched 1:1 case control-adjusted Kaplan-Meier analyses and Cox regression models were performed to investigate the impact of prior cancer on overall survival (OS). Results: Among 20,987 patients with laryngeal cancer, nearly one-fifth (n = 3,915, 18.65%) had a prior cancer. The top three common prior cancers were prostate (588, 28.1%), lung and bronchus (354, 16.9%), and head and neck (306, 14.6%). A total of 73.4% of the prior cancers were diagnosed within 5 years of the laryngeal cancer diagnosis. Compared to patients without prior cancer, a worse survival was significantly associated with a prior cancer among laryngeal cancer patients, regardless of the interval time of the prior cancer (log-rank tests P < 0.001). Furthermore, prior cancer was an independent predictor of worse OS based on the Cox regression model [hazard ratio (HR) = 1.396, 95% confidence interval, 1.336-1.458]. In addition, patients with prior lung and bronchus cancer tended to have the worst survival (log-rank tests P < 0.001). Conclusions: Prior cancer has an adverse effect on clinical outcomes among patients with laryngeal cancer. These results suggest that individualized treatment should be seriously considered in patients with laryngeal cancer and a history of prior cancer, regardless of the interval time of prior cancer.
