A Ten Year Experience of Men's Health Events in a Socioeconomically Diverse City in the United States - Lessons Learned

Community-based health events provide an opportunity to increase knowledge, awareness, and screening for acute and chronic diseases among individuals living in a socioeconomically diverse community. Because there are limited reports of such events, here we describe our ten-year experience of annual men's health fairs. This retrospective study of the Michigan Institute of Urology Foundation evaluated Men's Health Events held in Detroit, Michigan, from 2012 to 2021. Over 10 years, 11,129 men were screened and > 100,000 screenings were performed. The majority of the attendees were African-American men (61%), had a college degree (67%) or a high school diploma (26%), and had an annual income of <$35K (47%) or $35-60 K (30%). From 2012 to 2021, participants who saw a doctor in the past year rose from 62 to 70%; the median age of men rose from 52 to 58; their median testosterone levels increased from 353 ng/dL to 412 ng/dL, and men with concerning prostate-specific antigen values (≥ 4 ng/mL) doubled from 5% to 10%. Among participants, 59% had cholesterol levels of < 200 mg/dL, 28% of 200-240 mg/dL, and 13% of > 240 mg/dL; 7% had glucose levels of < 70 mg/dL, 68% of 70-105 mg/dL, and 25% of > 105 mg/dL ; 24% had ≥ 140 mmHg systolic and 18% had ≥ 90 mmHg diastolic blood pressure. Our findings suggest that community health events are successful at attracting and screening diverse community members. Such events should emphasize screening of high-risk individuals for acute and chronic diseases and promote other health-related behaviors.

Existing Health Inequities in the Treatment of Advanced and Metastatic Cancers

PURPOSE OF REVIEW

This study aims to identify health inequities related to the medical treatment and supportive care of patients with advanced/metastatic cancer and recommend solutions to promote health equity.

RECENT FINDINGS

Despite robust strides in the development of therapeutic strategies for advanced and metastatic cancer, significant disparities in treatment access and implementation exist. Race, socioeconomic status, gender, and geography represent just a few of the individual-level factors which contribute to challenges in treatment administration, thorough evaluation of germline genetics and tumor genomics, and quality palliative and end-of-life care. Given the increasing complexity of cancer treatments and our enhanced understanding of tumor biology, efforts to uniformly provide equitable and high-level care to all patients are needed. In this review we will discuss factors that contribute to health inequities in patients with advanced and metastatic cancer diagnoses, highlighting opportunities for intervention, ongoing challenges in change implementation, and national and international society recommendations to eliminate disparities. Acknowledging existing inequities and engaging in multilevel discourse with key stakeholders is needed to optimize care practices to the benefit of all patients.

Racial disparities in presenting stage and surgical management among octogenarians with breast cancer: a national cancer database analysis

BACKGROUND

As the US faces a diverse aging population, racial disparities in breast cancer outcomes among elderly patients remain poorly understood. We evaluate the association of race with presenting stage, treatment, and survival of invasive breast cancer among octogenarians.

METHODS

Women (≥ 80 years) with invasive breast cancer were identified in 2004-2020 NCDB. To facilitate comparison, only non-Hispanic Black and non-Hispanic White patients were included; patients of Hispanic ethnicity were excluded. Demographics, tumor characteristics, and treatments were assessed by race. Overall survival was compared using the logrank test. Multivariable logistic and Cox proportional hazard regression models were developed to evaluate the independent association of race with outcomes of interest.

RESULTS

Of 222,897 patients, 19,059 (8.6%) were Black. Most patients had stage I ER + HER2- invasive ductal carcinoma. Black patients more frequently had greater comorbidities, low income and education, and advanced stage (p < 0.001 each; ref: White). Following adjustment, Black women had increased likelihood of Stage III/IV over time, as well as increased odds of chemotherapy (AOR 1.22, 95% CI 1.15 - 1.29) and non-operative management (AOR 1.82, 95% CI 1.72 - 1.92; ref: White). Although Black patients had lower survival rates compared to White, race was not associated with 5-year mortality following adjustment for stage, receipt of surgery, and adjuvant treatments (p = 0.34).

CONCLUSIONS

Inferior survival among elderly Black patients appears be driven by advanced stage at presentation. While such disparities are narrowing in the present era, future work must consider upstream interventions to ensure equitable outcomes for all races.

Phenolics in soymilk manufactured from black and Proto soybeans by two continuous-ultrahigh-temperature-processing technologies inhibit DU145-prostate cancer cell proliferation through apoptosis

Plant genotypes and processing technologies affect health properties of foods. How thermal processes with different sterilization values influence polyphenols in soymilk manufactured from different genotypes, particularly black soybean has not been well characterized. This study's aims were to investigate how one- and two-phase ultrahigh temperature (UHT) processing technologies, with wide differences of lethality (F0 158.5 and 6.35, respectively), affected anti-prostate cancer DU145-cell properties of black soymilk compared to light-yellow-Proto soymilk. Phenolics were extracted from soymilk and used for chemical, cell cycle and apoptosis analyses. Total isoflavones and genistein in black soymilk were significantly higher than Proto soymilk by either processing methods. Compared to one-phase processing, two-phase produced higher gallic acid in both soybeans, and higher oxygen radical absorbance capacity (ORAC) in black soymilk. Soymilk processed from both genotypes by both UHT methods inhibited DU145 cells. Two-phase-UHT processed black soymilk was more effective than one-phase UHT-processed soymilk. IC50 values (mg/mL) of black and yellow soy extracts against prostate cancer cells differed only by 11%-25%, which were lower than the differences of total isoflavone (29%-33%) or genistein (>50% between two beans). The mechanism by which soymilk inhibited DU145 cell proliferation was through apoptosis as evidenced by cell cycle analyses and expressions of caspase-3, Bcl-2, and PARP-1 proteins. Antioxidant properties, isoflavones, and phenolic acids were negatively correlated with prostate-cancer-cell inhibition IC50 (p < 0.05) with ORAC having the highest coefficient (r = -0.98). Overall, two-phase-UHT processing of soybean would produce soymilk products with a higher health benefit than a one-phase UHT method. PRACTICAL APPLICATION: This study characterized the potential prostate cancer prevention effect of soymilk's phenolic extract in black soybean and compared with yellow soybean. The crude extract can be prepared much less costly than purified isoflavones and has potential to be developed into a dietary supplement. This study shows differences of soymilks made by continuous high-temperature processing of two soybean types and can serve as a scientific foundation for future clinical research and commercialization.

An outlook of docking analysis and structure-activity relationship of pyrimidine-based analogues as EGFR inhibitors against non-small cell lung cancer (NSCLC)

Almost 80% of lung cancer diagnoses each year correspond to non-small cell lung cancer (NSCLC). The percentage of NSCLC with EGFR overexpression ranges from 40% to 89%, with squamous tumors showing the greatest rates (89%) and adenocarcinomas showing the lowest rates (41%). Therefore, in NSCLC therapy, blocking the EGFR-driven pathway by inhibiting the intracellular tyrosine kinase domain of EGFR has exhibited significant improvement. In this view, several small molecules particularly pyrimidine/fused pyrimidine scaffolds were intended for molecular hybridization to develop EGFR-TK inhibitors. However, the associated limitation such as resistance and genetic mutation along with adverse effects, constrained the long-term treatment and effectiveness of such medication. Therefore, in recent years, pyrimidine derivatives were uncovered as potential EGFR TKIs. The present review summarised the research progress of EGFR TKIs to dazed structure-activity relationship, biological evaluation, and comparative docking studies of pyrimidine compounds. We have added the comparative docking analysis followed by the molecular simulation study against the four different PDBs of EGFR to strengthen the already existing research. Docking analysis unfolded that compound 14 resulted as noticeable with all different PDB and managed to interact with some of the crucial amino acid residues. From a future perspective, researchers must develop a more selective inhibitor, that can selectively target the mutation. Our review will support medicinal chemists in the direction of the development of novel pyrimidine-based EGFR TKIs.Communicated by Ramaswamy H. Sarma.

Perceived Barriers to Pap Screening Influence Adherence to Screening Recommendations Among Black Women

Objectives: The aim of this study was to determine the Health Belief Model (HBM) constructs associated with Pap screening adherence among a sample of African American and sub-Saharan African immigrant women in the United States. Methods: A descriptive cross-sectional study was conducted via an online survey. Participants were recruited from central Kentucky counties. Ninety-one eligible women participated (mean age 38 ± 12 years), 49.5% identified as African American. Twenty-nine percent indicated never being screened or not being up-to-date. Self-reported demographic data, HBM constructs for Pap screening, and Pap screening history were collected. Bivariate and logistic regressions were performed. Results: There was a significant negative association between perceived barriers and being up-to-date. For every one-point increase in perceived barriers, the odds of being up-to-date decreased by 81%, (p = 0.004; CI: 0.06-0.60), findings from further evaluation of the barrier construct showed that barriers significantly associated with screening include items related to lack of knowledge about where to get a Pap screening, lack of time to attend the screening, screening-associated shame and pain, negligence, and age. There were no other significant HBM constructs associated with up-to-date Pap screening status. There was no difference in perceived barriers between African American and sub-Saharan African women. Conclusions: Despite public health efforts to decrease screening barriers, a perception of barriers exists among Black women. Continued efforts to address screening barriers as well as the perception of barriers are warranted among Black women.

Cross-Cultural Adaptation and Psychometric Validation of the Interview Satisfaction Questionnaire (ISQ) to Assess Unmet Health Communication Needs of Iranian Breast Cancer Patients

Autonomous and patient-centered health communication (PCHC) between a healthcare provider (HCP) and a client (HCC) is a critical fundament for successful healthcare outcomes. A standard and validated data collection tool for studying the satisfaction of Iranian breast cancer patients (BCPs) with various aspects of their health communication with HCPs does not exist. The current study assessed the application, feasibility, and cultural appropriateness of the Persian-translated version of the interview satisfaction questionnaire (ISQ) in the Iranian context. A standard translation/back-translation procedure was used to prepare a preliminary Persian version of the ISQ (ISQ-P) which was then evaluated for content and face validity by a panel of experts. The study data were collected from 200 breast cancer patients and used to estimate the internal consistency measure of Cronbach's alpha and intra-class correlation coefficient. Confirmatory factor analysis (CFA) was performed to verify the compatibility of the instrument's identified dimensions with the original ISQ's factor structure. The calculated content validity index (CVI = 0.89), content validity ratio (CVR = 0.49), and Cronbach's alpha coefficient (0.79) indicated the appropriateness of the ISQ-P for its intended purpose. The CFA's outputs (root mean square error of approximation (RMSEA) = 0.09, comparative fit index (CFI) = 0.954, Tucker-Lewis index (TLI) = 0.931, standardized root mean square residual (SRMR) = 0.04) affirmed the fitness of the study data to the original 4-factor conceptual model. The study findings supported the suitability of ISQ-P for assessing health communication episodes by Persian-speaking BCPs. However, due to cultural variation, cross-border diversity of health systems, and organizational circumstances, further validity and reliability appraisal of the ISQ-P in distinct sub-samples is recommended.

Incidence of prostate cancer in Medicaid beneficiaries with and without HIV in 2001-2015 in 14 states

Prostate cancer (PCa) incidence is reportedly lower in men with HIV compared to men without HIV for unknown reasons. We describe PCa incidence by HIV status in Medicaid beneficiaries, allowing for comparison of men with and without HIV who are similar with respect to socioeconomic characteristics and access to healthcare. Men (N = 15,167,636) aged 18-64 with ≥7 months of continuous enrollment during 2001-2015 in 14 US states were retained for analysis. Diagnoses of HIV and PCa were identified using non-drug claims. We estimated cause-specific (csHR) comparing incidence of PCa by HIV status, adjusted for age, race-ethnicity, state of residence, year of enrollment, and comorbid conditions, and stratified by age and race-ethnicity. Hazard of PCa was lower in men with HIV than men without HIV (csHR = 0.89; 95% CI: 0.80, 0.99), but varied by race-ethnicity, with similar observations among non-Hispanic Black (csHR = 0.79; 95% CI: 0.69, 0.91) and Hispanic (csHR = 0.85; 95% CI: 0.67, 1.09), but not non-Hispanic white men (csHR = 1.17; 95% CI: 0.91, 1.50). Findings were similar in models restricted to men aged 50-64 and 40-49, but not in men aged 18-39. Reported deficits in PCa incidence by HIV status may be restricted to specific groups defined by age and race ethnicity.

Young Black Women's Breast Cancer Knowledge and Beliefs: A Sequential Explanatory Mixed Methods Study

INTRODUCTION

Black women under the age of 50 have a 111% higher breast cancer mortality rate than their White counterparts. The breast cancer mortality disparities among young Black women may be due in part to the fact that they are more likely to be diagnosed with late-stage, invasive breast cancer tumors. Psychosocial factors, such as lack of perceived risk for breast cancer, lack of awareness of breast cancer risk factors, and ambiguity about breast cancer screening guidelines are areas that are under investigated among young Black women. The purpose of this study was to identify young Black women's cancer beliefs and level of breast cancer risk knowledge.

METHODS

A sequential explanatory mixed methods study was conducted using quantitative data from the Health Information Trends Survey 6 (HINTS 6) (n = 25) and qualitative data from interviews with young Black female college students (n = 13). The results of the quantitative data analysis were used to guide the development of the qualitative interview guide. Data regarding participants' cancer beliefs, cancer risk factor knowledge, perceived cancer risk, and ambiguity about cancer screening behaviors were analyzed.

RESULTS

The findings indicated young Black women have low perceived risk of developing cancer. Most participants were not aware of cancer recommendations that were targeted towards women under the age of 40. In addition, knowledge about lifestyle behavior risk factors for breast cancer was relatively low.

CONCLUSION

Our findings underscore the importance of developing, disseminating, and implementing breast cancer education interventions that are targeted towards young Black women.

Initiatives to increase breast and cervical cancer-related knowledge, screening, and health behaviours among Black women

SETTING

In Canada, racialized and immigrant women are typically under-screened for breast and cervical cancer. Under-screening is linked to numerous barriers to access, including lack of awareness, fear of pain, the stigma of cancer, socio-cultural factors like language, and various socio-economic factors. To address these barriers, our team developed a series of initiatives to promote awareness of breast and cervical health among Black women.

INTERVENTION

Building on the development of a breast cancer resource hub for Black women, and in partnership with relevant community organizations, we implemented a series of virtual educational and cancer screening events (two of each thus far). Both event series were targeted towards Black women and tailored to their needs.

OUTCOMES

Each educational event attracted more than 450 attendees and had average attendance times > 1 h. Most (> 87%) survey respondents agreed that an event specifically for Black women helped them feel supported. The 2022 and 2023 screening events provided breast and/or cervical cancer screening for 46 and 48 women, respectively. In both years, most women (> 90% of question respondents) noted that they were (extremely) likely to go for a mammogram or Pap test when next due.

IMPLICATIONS

Both event series provided targeted opportunities for Black women to learn about prevention, risk factors, resources, and screening related to women's cancers. It is possible that, over time, such culturally tailored events can reduce or remove the stigmas associated with cancer and decrease differences in cancer-related knowledge and behaviours between racialized and non-racialized groups.

Differentiation between high-grade gliomas and solitary brain metastases based on multidiffusion MRI model quantitative analysis

Background and purpose

Differentiating high-grade gliomas (HGGs) from solitary brain metastases (SBMs) using conventional magnetic resonance imaging (MRI) remains challenging due to their similar imaging features. This study aimed to evaluate the diagnostic performance of advanced diffusion models, such as neurite orientation dispersion and density imaging (NODDI) and mean apparent propagator magnetic resonance imaging (MAP-MRI), incomparison to traditional techniques like diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), and diffusion kurtosis imaging (DKI) for distinguishing HGGs from SBMs.

Methods

In total, 17 patients with HGGs and 26 patients with SBMs were prospectively recruited based on the established inclusion and exclusion criteria. Structural MRI sequences and diffusion spectrum imaging (DSI) were utilized to assess quantitative parameter models, including NODDI, MAP-MRI, DWI, DTI, and DKI. Quantitative parameters were measured for both the tumor parenchymal area and the peritumoral edema area. The quantitative parameters of the two patient groups were compared using either the independent Student's t-test or the Mann-Whitney U test. The effectiveness of each model was evaluated using receiver operating characteristic (ROC) curves and calculating the area under the curve (AUC). Finally, the DeLong test was employed to compare the diagnostic performance of each model through pairwise comparisons of ROC curves.

Results

Isotropic volume fraction (Viso) based on NODDI; mean squared displacement (MSD) and the return to plane probabilities (RTPP) based on MAP-MRI; radial diffusivity (RDk) and mean diffusivity (MDk) based on DKI; and axial diffusivity (AD), radial diffusivity (RD), and mean diffusivity (MD) based on DTI of the peritumoral edema tumor were significantly different between HGGs and SBMs (p < 0.05). The optimal single discriminant parameters for each model are NODDI_Viso, MAP-MRI_MSD, DKI_MDk, and DTI_AD. Among these, the AUC of Viso (0.809) exceeds that of MSD (0.733), MDk (0.718), and AD (0.779). The combined model, which incorporates DTI_AD, DKI_RD, and NODDI_Viso, demonstrated superior diagnostic performance (0.897).

Conclusions

Advanced diffusion MRI quantitative parameters derived from NODDI, such as Viso, have the potential to enhance the differentiation between HGGs and SBMs. The integrated utilization of these models is anticipated to enhance diagnostic accuracy and refine MRI protocols for brain tumor assessment.

Age to Initiate Routine Breast Cancer Screening

This Clinical Practice Update provides revised guidance on the age to start routine breast cancer screening with mammography. This document is a focused update of related content in Practice Bulletin No. 179, Breast Cancer Risk Assessment and Screening in Average-Risk Women (Obstet Gynecol 2017;130:e1-16).

Fully Interpretable Deep Learning Model Using IR Thermal Images for Possible Breast Cancer Cases

Breast cancer remains a global health problem requiring effective diagnostic methods for early detection, in order to achieve the World Health Organization's ultimate goal of breast self-examination. A literature review indicates the urgency of improving diagnostic methods and identifies thermography as a promising, cost-effective, non-invasive, adjunctive, and complementary detection method. This research explores the potential of using machine learning techniques, specifically Bayesian networks combined with convolutional neural networks, to improve possible breast cancer diagnosis at early stages. Explainable artificial intelligence aims to clarify the reasoning behind any output of artificial neural network-based models. The proposed integration adds interpretability of the diagnosis, which is particularly significant for a medical diagnosis. We constructed two diagnostic expert models: Model A and Model B. In this research, Model A, combining thermal images after the explainable artificial intelligence process together with medical records, achieved an accuracy of 84.07%, while model B, which also includes a convolutional neural network prediction, achieved an accuracy of 90.93%. These results demonstrate the potential of explainable artificial intelligence to improve possible breast cancer diagnosis, with very high accuracy.

Artificial intelligence model for enhancing the accuracy of transvaginal ultrasound in detecting endometrial cancer and endometrial atypical hyperplasia

OBJECTIVES

Transvaginal ultrasound is typically the initial diagnostic approach in patients with postmenopausal bleeding for detecting endometrial atypical hyperplasia/cancer. Although transvaginal ultrasound demonstrates notable sensitivity, its specificity remains limited. The objective of this study was to enhance the diagnostic accuracy of transvaginal ultrasound through the integration of artificial intelligence. By using transvaginal ultrasound images, we aimed to develop an artificial intelligence based automated segmentation model and an artificial intelligence based classifier model.

METHODS

Patients with postmenopausal bleeding undergoing transvaginal ultrasound and endometrial sampling at Mayo Clinic between 2016 and 2021 were retrospectively included. Manual segmentation of images was performed by four physicians (readers). Patients were classified into cohort A (atypical hyperplasia/cancer) and cohort B (benign) based on the pathologic report of endometrial sampling. A fully automated segmentation model was developed, and the performance of the model in correctly identifying the endometrium was compared with physician made segmentation using similarity metrics. To develop the classifier model, radiomic features were calculated from the manually segmented regions-of-interest. These features were used to train a wide range of machine learning based classifiers. The top performing machine learning classifier was evaluated using a threefold approach, and diagnostic accuracy was assessed through the F1 score and area under the receiver operating characteristic curve (AUC-ROC).

RESULTS

302 patients were included. Automated segmentation-reader agreement was 0.79±0.21 using the Dice coefficient. For the classification task, 92 radiomic features related to pixel texture/shape/intensity were found to be significantly different between cohort A and B. The threefold evaluation of the top performing classifier model showed an AUC-ROC of 0.90 (range 0.88-0.92) on the validation set and 0.88 (range 0.86-0.91) on the hold-out test set. Sensitivity and specificity were 0.87 (range 0.77-0.94) and 0.86 (range 0.81-0.94), respectively.

CONCLUSIONS

We trained an artificial intelligence based algorithm to differentiate endometrial atypical hyperplasia/cancer from benign conditions on transvaginal ultrasound images in a population of patients with postmenopausal bleeding.

Race- associated molecular differences in uterine serous carcinoma

Purpose

Endometrial cancer (EMCA) is the most common gynecologic malignancy, and new diagnoses are increasing in the United States. Black patients are more likely to present with advanced stage, be diagnosed with high-risk uterine serous carcinoma (USC) and die of their cancer.

Methods

Patients with endometrial adenocarcinoma who received tumor FoundationOne CDx testing at our institution between January 2017 and August 2022 were identified. Genomic alterations, demographic and clinical characteristics were collected. Descriptive statistics and Fisher's exact test were used to analyze data.

Results

A total of 289 patients (29.4% Black and 52.6% White) with advanced or recurrent endometrial adenocarcinoma underwent FoundationOne CDx testing. USC comprised 26.3% (76 of 289) of tested tumors. Of USC tumors, 33 of 76 (44%) were of Black race. USC occurred more frequently in Black patients (33 of 85 [38.8%] Black patients compared to 30 of 152 [19.7%] White patients, p<0.05). Among USC, CCNE1 amplification occurred more frequently in Black patients than in White patients (12 of 33 [36.36%] vs 2 of 30 [6.67%], p<0.05) while PI3K/AKT/mTOR pathway mutations occurred less frequently (16 of 33 [48.5%] vs 26 of 33 [86.7%], p=0.17). Among patients with CCNE1 amplification 73.3% (11 of 15) progressed on or within 12 months of first-line platinum-based therapy. CCNE1 amplification had significantly shorter median overall survival (97.3 months vs 44.3; HR (95%CI): 7.1 (10.03, 59.4) p< 0.05).

Conclusions

Black patients constituted 44% of patients with USC in our study and had an increased frequency of CCNE1 amplification. Patients whose tumors harbored CCNE1 amplification had shorter overall survival. Identifying actionable mutations in this high unmet need population is crucial to improving outcomes among Black patients with uterine malignancy. Development of new targeted-therapies will need to keep these alterations at the forefront as trials are being designed.

Understanding Perceptions of Care Coordination and Chronic Illness Management among Black Breast and Prostate Cancer Survivors and Providers: Findings from a Quality Improvement Study

Navigating cancer care is complex and is exacerbated by pre-existing comorbidities managed by multiple providers. In this quality improvement study, we evaluated changes in perceived care coordination, navigation, and chronic illness care with community health worker (CHW) and mHealth support among Black breast cancer and prostate cancer patients with hypertension and/or diabetes. We collected patient and provider surveys on chronic illness care coordination at baseline and six months and found improvements in multiple domains. These findings support engaging CHWs to improve care coordination among cancer patients with comorbidities and demonstrate a use case of importance with emerging navigation reimbursement policies.

Impact of Clinical Trial Design on Recruitment of Racial and Ethnic Minorities

Knowledge related to how oncology treatment trial design influences enrollment of racial and ethnic minorities is limited. Rigorous identification of clinical trial design parameters that associate favorably with minority accrual provides educational opportunities for individuals interested in designing more representative treatment trials. We identified oncology trials with a minimum of 10 patients at an NCI-Designated Comprehensive Cancer Center from 2010 to 2021. We defined a study endpoint of racial and ethnic minority accrual greater than zero. Multivariable logistic regression was used to determine whether co-variables predicted our study endpoint. P-values of less than 0.05 were considered significant. A total of 352 cancer trials met eligibility criteria. These studies enrolled a total of 7981 patients with a total of 926 racial and ethnic minorities leading to a median enrollment of 10%. Trials open in community sites (yes versus no) were more likely to have a minority patient (OR, 2.21; 95% CI, 1.02-4.96) as well as pilot/phase I studies compared to phase II/III (OR, 3.19; 95% CI, 1.34-8.26). Trials incorporating immunotherapy (yes versus no) were less likely to have a minority patient (OR, 0.47; 95% CI, 0.23-0.94). Trials open in community sites as well as early phase treatment studies were more likely to accrue minority patients. However, studies including immunotherapy were less likely to accrue racial and ethnic minorities. Knowledge gained from our analysis may help individuals design oncology treatment trials that are representative of more diverse populations.

Defining the Need for Services for Patients at High Risk of Breast Cancer at a Safety-Net Hospital: An Approach to Narrowing the Disparities Gap

BACKGROUND

The National Accreditation Program for Breast Cancer (NAPBC) standards were recently revised to promote breast cancer (BC) risk assessment and subsequent referral for high-risk services. This project sought to estimate the proportion of patients at high risk for BC in the authors' safety-net hospital system, gauge patient interest in high-risk services, and define resources for program development.

METHODS

Women presenting for breast imaging during 2 weeks in 2023 were surveyed. Thirty-five patients with a history or diagnosis of BC were excluded. The Tyrer-Cuzick (TC) model version 8 was used to calculate BC risk. High/intermediate risk was defined as a 10-year risk of 5% or more, a lifetime risk of 15% or more, or both. The criteria for genetic counseling and testing referral were based on National Comprehensive Cancer Network guidelines.

RESULTS

A total of 257 patients had a TC risk assessment showing 14.8% (n = 38) with a 10-year BC risk of 5% or more (consideration of endocrine therapy), 6.2% (n = 16) with a lifetime BC risk of 20% or more (qualifying for annual screening MRI), and 10.5% (n = 27) with a lifetime BC risk of 15% or more (consideration of high-risk screening). The criteria for genetic counseling/testing were met by 61 (23.7%) of the 257 patients. Overall, 31.5% (n = 81) qualified for high/intermediate-risk screening, risk reduction, and/or genetic assessment/testing, 92.8% of whom were interested in referrals for additional information and care.

CONCLUSIONS

In the authors' community, almost one third of patients undergoing breast imaging qualify for BC high-risk assessment and services. The majority of the patients expressed interest in pursuing such services. These data will be used in financial planning and resource allocation to develop a high-risk program at the authors' institution in line with NAPBC guidelines. They are hopeful that these efforts will improve oncologic outcomes and survival from BC in their community.

Amplification of MYC and Its Enhancer Correlates With Genetic Ancestry in Lung Squamous Cell Carcinoma

PURPOSE

In lung squamous cell carcinoma (LUSC), Black patients show significantly higher incidence and lower overall survival than White patients. Although socioeconomic factors likely contribute to this survival disparity, genomic factors have yet to be elucidated in LUSC.

METHODS

Using 416 LUSC tumor samples in the Cancer Genome Atlas (TCGA), we assessed genomic and transcriptomic profiles by ancestry. We replicated our analyses in pan-cancer data from TCGA, the American Association of Cancer Research (AACR) Genomics Evidence Neoplasia Information Exchange (GENIE), and Columbia University Medical Center.

RESULTS

We found increased MYC amplification, LUSC-specific MYC enhancer amplification, and chromosome arm 8q (chr8q) gain to be significantly associated with genetic AFR (African) ancestry in LUSC in TCGA. Furthermore, expression of MYC target genes was significantly enriched in AFR samples. Local ancestry analysis identified correlation of chr8q gain with AFR ancestry at the MYC locus in TCGA. We also found a significant correlation between chr8q and AFR ancestry in multiple cancer types and pan-cancer in TCGA. Similarly, in a pan-cancer subset of AACR GENIE data, we found a significant correlation between chr8q gain and race.

CONCLUSION

Together, our data suggest that ancestry may influence amplification of not only MYC but also its enhancer in LUSC. They also suggest a role for genetic ancestry in chr8q aneuploidy in cancer. These studies further define and expand patients who may benefit from future anti-MYC therapeutic approaches.

Health Disparities among Patients with Cancer Who Received Molecular Testing for Biomarker-Directed Therapy

Health disparities present a barrier to successful oncology treatment. The potential for precision oncology to reduce health disparities has not previously been analyzed. We performed a retrospective analysis of 12,627 patients from six major cancer centers whose tumors underwent molecular testing at Caris Life Sciences between 2010 and 2020. Kaplan-Meier and Cox regression were used to describe and analyze overall survival. The molecular and demographic features of the cohort were analyzed by χ2 and ANOVA tests. Black patients composed 25% of the cohort and White patients 63%. Among this molecularly-tested cohort, there were minimal outcome differences based on race, geographic location, or poverty level. When analyzing the interaction of age, race, and sex, racial-based disparities were noted primarily for young non-White women in the study cohort but were more pronounced for men and women of all ages in the broader patient population within the Surveillance, Epidemiology, and End Results database. Mutations in five genes-APC, EGFR, STK11, TP53, and KRAS-were found to affect overall survival among our cohort, and their prevalence varied by race in specific tumor types. Real-world outcomes data in mutation-defined cohorts also provided additional context to previously reported therapeutic response trends. Our study shows that patients who undergo molecular testing display reduced racial health disparities compared with the general population, whereas persistent racial disparities are influenced by age and sex. Genomic-driven racial disparities should be examined at a tumor lineage-specific level. Increased access to molecular testing for all eligible patients may play a role in improving health equity. Significance: This study is the largest of its kind to analyze health disparities and genomic features among a diverse multiinstitutional cohort of patients who underwent molecular testing. Continuing to increase awareness of and access to molecular testing approaches may help to reduce cancer health disparities and improve outcomes for all patients.

The American Cancer Society National Lung Cancer Roundtable strategic plan: Optimizing strategies for lung nodule evaluation and management

Lung nodules are frequently detected on low-dose computed tomography scans performed for lung cancer screening and incidentally detected on imaging performed for other reasons. There is wide variability in how lung nodules are managed by general practitioners and subspecialists, with high rates of guideline-discordant care. This may be due in part to the level of evidence underlying current practice guideline recommendations (primarily based on findings from uncontrolled studies of diagnostic accuracy). The primary aims of lung nodule management are to minimize harms of diagnostic evaluations while expediting the evaluation, diagnosis, and treatment of lung cancer. Potentially useful tools such as lung cancer probability calculators, automated methods to identify patients with nodules in the electronic health record, and multidisciplinary team evaluation are often underused due to limited availability, accessibility, and/or provider knowledge. Finally, relatively little attention has been paid to identifying and reducing disparities among individuals with screening-detected or incidentally detected lung nodules. This contribution to the American Cancer Society National Lung Cancer Roundtable Strategic Plan aims to identify and describe these knowledge gaps in lung nodule management and propose recommendations to advance clinical practice and research. Major themes that are addressed include improving the quality of evidence supporting lung nodule evaluation guidelines, strategically leveraging information technology, and placing emphasis on equitable approaches to nodule management. The recommendations outlined in this strategic plan, when carried out through interdisciplinary efforts with a focus on health equity, ultimately aim to improve early detection and reduce the morbidity and mortality of lung cancer. PLAIN LANGUAGE SUMMARY: Lung nodules may be identified on chest scans of individuals who undergo lung cancer screening (screening-detected nodules) or among patients for whom a scan was performed for another reason (incidental nodules). Although the vast majority of lung nodules are not lung cancer, it is important to have evidence-based, standardized approaches to the evaluation and management of a lung nodule. The primary aims of lung nodule management are to diagnose lung cancer while it is still in an early stage and to avoid unnecessary procedures and other harms.

Safety of dostarlimab in combination with chemotherapy in patients with primary advanced or recurrent endometrial cancer in a phase III, randomized, placebo-controlled trial (ENGOT-EN6-NSGO/GOG-3031/RUBY)

Background

In Part 1 of the phase III RUBY trial (NCT03981796) in patients with primary advanced or recurrent endometrial cancer (EC), dostarlimab plus carboplatin-paclitaxel (CP) significantly improved progression-free survival and overall survival compared with CP alone. Limited safety data have been reported for the combination of immunotherapies plus chemotherapy in this setting.

Objectives

The objective of this analysis was to identify the occurrence of treatment-related adverse events (TRAEs) and immune-related adverse events (irAEs) and to describe irAE management in Part 1 of the RUBY trial.

Design

RUBY is a phase III, randomized, double-blind, multicenter study of dostarlimab plus CP compared with CP alone in patients with primary advanced or recurrent EC.

Methods

Patients were randomized 1:1 to dostarlimab 500 mg, or placebo, plus CP every 3 weeks for 6 cycles, followed by dostarlimab 1000 mg, or placebo, every 6 weeks for up to 3 years. Adverse events (AEs) were assessed according to Common Terminology Criteria for Adverse Events, version 4.03.

Results

The safety population included 487 patients who received ⩾1 dose of treatment (241 dostarlimab plus CP; 246 placebo plus CP). Treatment-emergent AEs were experienced by 100% of patients in both arms. TRAEs occurred in 97.9% of the dostarlimab arm and 98.8% of the placebo arm.The most common TRAEs occurred at similar rates between arms and were mostly low grade. IrAEs occurred in 58.5% of patients in the dostarlimab arm and 37.0% of patients in the placebo arm. Dostarlimab- or placebo-related irAEs were reported in 40.7% of patients in the dostarlimab arm and 16.3% of the placebo arm.

Conclusion

The safety profile of dostarlimab plus CP was generally consistent with that of the individual components. Dostarlimab plus CP has a favorable benefit-risk profile and is a new standard of care for patients with primary advanced or recurrent EC.

Disparities in Musculoskeletal Oncology

PURPOSE OF REVIEW

Disparities within the healthcare system serve as barriers to care that lead to poor outcomes for patients. These healthcare disparities are present in all facets of medicine and extend to musculoskeletal oncology care. There are various tenets to health disparities with some factors being modifiable and non-modifiable. The factors play a direct role in a patient's access to care, time of presentation, poor social determinants of health, outcomes and survival.

RECENT FINDINGS

In musculoskeletal oncologic care, factors such as race, socioeconomic factors and insurance status are correlated to advanced disease upon presentation and poor survival for patients with a sarcoma diagnosis. These factors complicate the proper delivery of coordinated care that is required for optimizing patient outcomes. Healthcare disparities lead to suboptimal outcomes for patients who require musculoskeletal oncologic care in the short and long term. More research is required to identify ways to address the known modifiable and non-modifiable factors to improve patient outcome.

AI-assisted models to predict chemotherapy drugs modified with C60 fullerene derivatives

Employing quantitative structure-activity relationship (QSAR)/ quantitative structure-property relationship (QSPR) models, this study explores the application of fullerene derivatives as nanocarriers for breast cancer chemotherapy drugs. Isolated drugs and two drug-fullerene complexes (i.e., drug-pristine C60 fullerene and drug-carboxyfullerene C60-COOH) were investigated with the protein CXCR7 as the molecular docking target. The research involved over 30 drugs and employed Pearson's hard-soft acid-base theory and common QSAR/QSPR descriptors to build predictive models for the docking scores. Energetic descriptors were computed using quantum chemistry at the density functional-based tight binding DFTB3 level. The results indicate that drug-fullerene complexes interact more with CXCR7 than isolated drugs. Specific binding sites were identified, with varying locations for each drug complex. Predictive models, developed using multiple linear regression and IBM Watson artificial intelligence (AI), achieved mean absolute percentage errors below 12%, driven by AI-identified key variables. The predictive models included mainly quantitative descriptors collected from datasets as well as computed ones. In addition, a water-soluble fullerene was used to compare results obtained by DFTB3 with a conventional density functional theory approach. These findings promise to enhance breast cancer chemotherapy by leveraging fullerene-based drug nanocarriers.

Testing home-based exercise strategies in underserved minority cancer patients undergoing chemotherapy (THRIVE) trial: a study protocol

Background

Higher rates of physical inactivity and comorbid conditions are reported in Hispanic/Latinx and Black cancer patients receiving chemotherapy compared to their White counterparts. Despite the beneficial effect of exercise training for cancer patients, rates of participation in exercise oncology clinical trials are low among disadvantaged and racial and ethnic minority groups. Here, we will examine the effect of an exercise intervention using a novel, accessible, and cost-effective home-based exercise approach among Hispanic/Latinx and Black cancer patients receiving chemotherapy on exercise participation and cardiovascular disease risk.

Methods

The THRIVE trial is an 8-month prospective, three-arm study of 45 patients who are randomized in a 1:1:1 fashion to a supervised exercise intervention (SUP), unsupervised exercise (UNSUP), or an attention control (AC) group. Eligible patients include those with breast, colorectal, or prostate cancer, who are sedentary, overweight or obese, self-identify as Hispanic/Latinx or Black, and plan to receive chemotherapy. Patients randomized to the SUP group participate in a home-based 16-week periodized aerobic and resistance exercise program performed three days per week, supervised through video conference technology. Patients randomized to the UNSUP group participate in an unsupervised 16-week, telehealth-based, periodized aerobic and resistance exercise program performed three days per week using the same exercise prescription parameters as the SUP group. Patients randomized to the AC group receive a 16-week home-based stretching program. The primary outcome is changes in minutes of physical activity assessed by 7-day accelerometry at post-intervention. Secondary outcomes include cardiovascular risk factors, patient-reported outcomes, and physical function. Outcome measures are tested at baseline, post-intervention at month 4, and after a non-intervention follow-up period at month 8.

Discussion

The THRIVE trial is the first study to employ a novel and potentially achievable exercise intervention for a minority population receiving chemotherapy. In addition, this study utilizes an intervention approach to investigate the biological and behavioral mechanisms underlying exercise participation in these cancer patients. Results will guide and inform large randomized controlled trials to test the effect of home-based exercise on treatment outcomes and comorbid disease risk in minority patients with cancer undergoing chemotherapy.

Single-cell sequencing analysis of multiple myeloma heterogeneity and identification of new theranostic targets

Multiple myeloma (MM) is a heterogeneous and incurable tumor characterized by the malignant proliferation of plasma cells. It is necessary to clarify the heterogeneity of MM and identify new theranostic targets. We constructed a single-cell transcriptome profile of 48,293 bone marrow cells from MM patients and health donors (HDs) annotated with 7 continuous B lymphocyte lineages. Through CellChat, we discovered that the communication among B lymphocyte lineages between MM and HDs was disrupted, and unique signaling molecules were observed. Through pseudotime analysis, it was found that the differences between MM and HDs were mainly reflected in plasma cells. These differences are primarily related to various biological processes involving mitochondria. Then, we identified the key subpopulation associated with the malignant proliferation of plasma cells. This group of cells exhibited strong proliferation ability, high CNV scores, high expression of frequently mutated genes, and strong glucose metabolic activity. Furthermore, we demonstrated the therapeutic potential of WNK1 as a target. Our study provides new insights into the development of B cells and the heterogeneity of plasma cells in MM and suggests that WNK1 is a potential therapeutic target for MM.

High expression of small nucleolar host gene RNA may predict poor prognosis of Hepatocellular carcinoma, based on systematic reviews and meta-analyses

BACKGROUND

The prognosis of patients with hepatocellular cancer is substantially correlated with the abnormal expression of growing long non-coding RNA small nucleolar host gene RNA (SNHG) families in liver cancer tissues. This study aimed to examine the relationship between SNHG expression and liver cancer prognosis.

METHODS

After searching six internet databases, pertinent manuscripts were found based on inclusion and exclusion criteria. To determine whether SNHG expression levels affect liver cancer prognosis, raw data were collected and hazard ratios (HRs) and odds ratios (ORs) were calculated. The results were examined for potential publication bias using the sensitivity analysis and Beeg's test.

RESULTS

Most SNHG family members were up-regulated in liver cancer tissues. High SNHG expression predicts poor liver cancer outcomes of, including overall survival (OS) (HR: 1.697, 95% confidence interval [CI]: 1.373-2.021), especially SNHG5 (the HR of OS is 4.74, 95%CI range from 1.35 to 6.64), progression-free survival (HR: 1.85, 95% CI: 1.25-2.73), tumor, node, metastasis (TNM) stage (OR: 1.696, 95% CI: 1.436-2.005), lymph node metastasis (OR: 2.383, 95% CI: 1.098-5.173), and tumor size (OR: 1363, 95% CI: 1.165-1.595). The OS results were found to be reliable and robust, as indicated by the sensitivity analysis. Additionally, Beeg's test demonstrated the absence of any potential publication bias for each result.

CONCLUSION

In liver cancer tissues, most SNHGs are highly expressed, which may signal poor prognosis. SNHG has the potential to be an intriguing predictive marker and a prospective therapeutic target for liver cancer.

18F-Flotufolastat Positron Emission Tomography in African American Patients With Suspected Prostate Cancer Recurrence: Findings From the Phase 3 SPOTLIGHT Study

Purpose

Although African American (AA) patients are disproportionately affected by prostate cancer, they are often underrepresented in oncology clinical trials. The SPOTLIGHT study (NCT04186845) assessed the novel diagnostic positron emission tomography radiopharmaceutical, 18F-flotufolastat (18F-rhPSMA-7.3), in patients with recurrent prostate cancer. The proportion of AA patients enrolled in SPOTLIGHT (17%) was greater than typically enrolled in oncology trials (8.5%) and was representative of the US population (14%). This post hoc analysis of SPOTLIGHT evaluates the diagnostic performance of 18F-flotufolastat in AA patients.

Methods and Materials

Patients underwent positron emission tomography/computed tomography 50 to 70 minutes after intravenous administration of 296 MBq 18F-flotufolastat. Three blinded readers evaluated all images, with the majority read (agreement of ≥2 readers) result reported here. Standard of truth (SoT) was established with histopathology or correlative imaging. Data from AA patients were evaluated to determine the 18F-flotufolastat overall detection rate (DR), positive predictive value (PPV), and verified DR (VDR). VDR (SoT-verified) is equivalent to DR × PPV.

Results

In total, 61 of 366 (17%) patients were AAs. Although baseline characteristics were broadly similar, fewer AA patients (56%) had undergone prostatectomy than non-AA patients (82%). The patient-level DR was 93% (57/61) in AA patients, increasing from 67% at prostate-specific antigen <0.5 ng/mL to 100% at prostate-specific antigen ≥10 ng/mL. Patient-level DR was marginally lower in all other patients (87%, 264/305). However, when stratifying by prior treatment, DRs were similar across ethnic groups in postprostatectomy patients, but in patients with intact prostates, AA patients had higher prostate DR than non-AA patients. SoT-verification (predominantly with conventional imaging [79%]) gave a VDR of 64% and PPV of 68% in AA patients, versus 55% and 64%, respectively, in all other patients.

Conclusions

18F-Flotufolastat DRs were marginally higher in AA patients than in all other patients enrolled in SPOTLIGHT. High VDR and PPV were also achieved in AA patients from across all participating centers, indicating the broad applicability of newly US Food and Drug Administration-approved 18F-flotufolastat to the US population as a whole.

Wirelessly Powered Visible Light-Emitting Implant for Surgical Guidance during Lumpectomy

Achieving negative surgical margins, defined as no tumor found on the edges of the resected tissue, during lumpectomy for breast cancer is critical for mitigating the risk of local recurrence. To identify nonpalpable tumors that cannot be felt, pre-operative placements of wire and wire-free localization devices are typically employed. Wire-free localization approaches have significant practical advantages over wired techniques. In this study, we introduce an innovative localization system comprising a light-emitting diode (LED)-based implantable device and handheld system. The device, which is needle injectable and wire free, utilizes multiple wirelessly powered LEDs to provide direct visual guidance for lumpectomy. Two distinct colors, red and blue, provide a clear indication of tissue depth: blue light is absorbed strongly in tissue, visible within a close range of <1 cm, while red light remains visible through several centimeters of tissue. The LEDs, integrated with an impedance-matching circuit and receiver coil, are encapsulated in biocompatible epoxy for injection with a 12 G needle. Our findings demonstrate that the implant exhibits clearly perceivable depth-dependent color changes and remains visible through >2 cm of ex vivo chicken breast and bovine muscle tissue using less than 4 W of transmitted power from a handheld antenna. These miniaturized needle-injectable localization devices show promise for improving surgical guidance of nonpalpable breast tumors.

Treatment Intensification in Metastatic Hormone-Sensitive Prostate Cancer: An Analysis of Real-World Practice Patterns from the CancerLinQ Database

BACKGROUND

In metastatic hormone-sensitive prostate cancer (mHSPC), androgen deprivation therapy and standard of care treatment intensification with docetaxel and/or an androgen receptor signaling inhibitor (ARSI) are associated with improved survival outcomes for appropriate patients.

METHODS

This retrospective study selected patients with de novo mHSPC diagnosed between 2014 and 2023 from CancerLinQ Discovery®, a United States (US)-based, de-identified clinical database. Patient-level data, including clinical characteristics, treatments, and demographics, were collected from CancerLinQ. Treatment intensification was defined as the use of docetaxel, abiraterone, apalutamide, enzalutamide, or docetaxel plus abiraterone or darolutamide. Patient characteristics and treatment intensification data were analyzed descriptively and using multivariable logistic regression.

RESULTS

Of the 3,684 patients with mHSPC, the overall rate of treatment intensification was 58.4% but increased from 32.5% in 2014 to 67.5% in 2023. A relative decline in docetaxel use was accompanied by an increase in ARSI use. Black patients with mHSPC were less likely to receive treatment identification (OR 0.78, 95% CI 0.64-0.95, P = 0.013). Treatment intensification was also less likely for patients of older age and increased ECOG performance status. Despite increasing treatment intensification for Black patients with mHSPC over time, rates of docetaxel use are disproportionately declining relative to White patients.

CONCLUSIONS

Treatment intensification rates are increasing to include the majority of patients with mHSPC. However, treatment disparities exist for Black patients, who are less likely to receive intensification. These findings illustrate the importance of promoting treatment intensification in appropriate patients and addressing racial treatment disparities.

Medical tattooing as a complementary cosmetic intervention to reduce body-image distress and mental health symptoms in U.S. breast cancer survivors

PURPOSE

A review of the literature revealed a high incidence of body-image distress among breast cancer survivors who had surgery. This cross-sectional study examined the relationship between medical tattooing as a complementary cosmetic intervention and body-image distress and mental health outcomes among breast cancer survivors following surgery.

METHODS

We examined 330 post-surgical breast cancer survivors collected through a nationwide online survey in the U.S., pursuing two main objectives. First, we investigated body-image distress, depression and anxiety symptoms, and perceived stress in survivors who underwent breast cancer surgery, comparing those with medical tattooing (n = 89) and those without (n = 226). Second, we assessed the influence of the participant's surgery type on body-image distress, depression and anxiety symptoms, and perceived stress. Additionally, we evaluated whether individual factors, such as appearance investment, satisfaction with decision, and cosmetic expectation discrepancy, predicted the participant's body-image distress.

RESULTS

Findings suggest that participants with medical tattoos reported significantly lower body-image distress, depression and anxiety symptoms, and perceived stress compared to those without medical tattoos. The participant's surgery type did not significantly predict body-image distress, depression or anxiety symptoms, or perceived stress. However, participants who reported greater appearance investment endorsed higher body-image distress. Participants who reported higher satisfaction with their treatment decisions and lower cosmetic expectation discrepancy endorsed lower body-image distress.

CONCLUSION

Medical tattooing may be a valuable tool in improving body-image distress and mental health for those who wish to pursue it, but more research is needed. Empirical studies supporting the mental health benefits of medical tattooing among survivors are crucial to standardize insurance coverage and promote its inclusion as a complementary intervention across insurance providers nationwide. This complementary intervention should be considered using a patient-centered approach that aligns with the patient's values and preferences.

Using a community-engaged research process to plan, implement, and evaluate a cancer education program to improve knowledge and screening intentions among African American men

OBJECTIVE

We assessed acceptability, feasibility, and preliminary efficacy of a culturally appropriate, cancer education program to improve cancer knowledge, attitudes, subjective norms, and screening intentions for oropharynx, colon, and prostate cancers among African American men. We detailed the community-engaged research process used for African American men to design, implement, and evaluate the program.

MATERIALS AND METHODS

We recruited 84 (61 in-person, 23 online) African American men over 2-months across 4 churches in Middle Tennessee in 2021. A single group, pre-post-test design was used to evaluate the 2.5-h hybrid program. Scales used were: General self-efficacy for cancer screening; attitudes toward cancer; general cancer knowledge; and subjective norms related to cancer. One-item measured cancer screening intention. Taba robust partial correlation measured the degree of association between changes in means of each explanatory variable with changes in means of each outcome variable. IBM SPSS version 28 and R/RStudio version 3.6.0 was used for data analysis. We conducted three focus groups (n = 17) to assess program acceptability. Microsoft Excel version 26 was used to conduct thematic analysis for this data.

FINDINGS

Quantitative Significant differences were found in the pre/post comparisons of knowledge (mean difference: 0.22; p-value = 0.015), self-efficacy (mean difference: 0.23; p-value < 0.001), and prostate cancer screening intention (mean difference: 0.19; p-value = 0.049) scores. This indicates the mean score for knowledge, self-efficacy, and prostate cancer screening intention was significantly higher post-intervention. Qualitative Focus group themes were: (1) Impact of Program on Participants Psychosocial Health (2) Perspectives on Life after the program. (3) Views on Programmatic Components; (4) Recommendations for Program Improvement.

CONCLUSIONS

Results demonstrate our program is feasible, acceptable, and could increase cancer screening intentions and behavior. Psychosocial providers should demonstrate cultural awareness and humility when providing services to address the psychological and social needs for cancer screening among African American men.

Urinary Metabolite Diagnostic and Prognostic Liquid Biopsy Biomarkers of Lung Cancer in Nonsmokers and Tobacco Smokers

PURPOSE

Nonsmokers account for 10% to 13% of all lung cancer cases in the United States. Etiology is attributed to multiple risk factors including exposure to secondhand smoking, asbestos, environmental pollution, and radon, but these exposures are not within the current eligibility criteria for early lung cancer screening by low-dose CT (LDCT).

EXPERIMENTAL DESIGN

Urine samples were collected from two independent cohorts comprising 846 participants (exploratory cohort) and 505 participants (validation cohort). The cancer urinary biomarkers, creatine riboside (CR) and N-acetylneuraminic acid (NANA), were analyzed and quantified using liquid chromatography-mass spectrometry to determine if nonsmoker cases can be distinguished from sex and age-matched controls in comparison with tobacco smoker cases and controls, potentially leading to more precise eligibility criteria for LDCT screening.

RESULTS

Urinary levels of CR and NANA were significantly higher and comparable in nonsmokers and tobacco smoker cases than population controls in both cohorts. Receiver operating characteristic analysis for combined CR and NANA levels in nonsmokers of the exploratory cohort resulted in better predictive performance with the AUC of 0.94, whereas the validation cohort nonsmokers had an AUC of 0.80. Kaplan-Meier survival curves showed that high levels of CR and NANA were associated with increased cancer-specific death in nonsmokers as well as tobacco smoker cases in both cohorts.

CONCLUSIONS

Measuring CR and NANA in urine liquid biopsies could identify nonsmokers at high risk for lung cancer as candidates for LDCT screening and warrant prospective studies of these biomarkers.

Diverse functions of Tribbles homolog 3 in cancers and its potential as a therapeutic target

Currently, cancer is the second leading cause of death worldwide, and potential targeted drugs and molecular pathways for cancer development and progression have been a hot research topic worldwide. In recent years, the importance of the kinase superfamily in diseases has been well demonstrated by studies on various molecular mechanisms of kinases and the successful application of their inhibitors in diseases. Pseudokinases are members of the kinase superfamily, which have been increasingly documented to play a crucial role in cancers year after year. As a member of pseudokinases, tribbles homolog 3 (TRIB3) also exerts diverse functions in different cancers through different interacting proteins and molecular pathways, especially in tumor immunity, stemness, drug resistance, metabolism, and autophagy. In addition, peptide drugs targeting TRIB3 have high specificity in preclinical studies, which shows great promise for TRIB3 application in diseases including cancers. In this review, we dissect diverse functions played by TRIB3 in different cancers, describing the underlying mechanisms in detail. Notably, inhibitors and agonists currently available for TRIB3 are discussed, indicating the potential for TRIB3 as a therapeutic target.

Care You Can Trust: How the Black Men's Health Clinic Leverages Community Partnerships Charting a Course Where Health Care Struggles to Reach

Black men in the United States have a lower life expectancy than Hispanic and White populations due to elevated morbidity and mortality from various health conditions. This is partially attributable to the experience of systemic racism and earned mistrust toward health professionals, the majority of whom are not Black. Despite recognition of this issue, limited progress has been made to improve Black men's health trajectories. Thus, there is an urgent need for health care organizations to reach more Black men and address existing health inequities through innovative means. Larry Wallace Sr., an experienced health care executive, recognized this issue in his community and created the Black Men's Health Clinic (BMHC) with his son, Larry Wallace Jr., to improve health care delivery to Black men in and around Austin, Texas. BMHC has successfully reached Black men in its catchment area through its strategic community engagement efforts and a unique financial model to increase health care accessibility for a population that has historically experienced poor health outcomes. Furthermore, they offer a comprehensive range of services that acknowledge the impact of social and structural determinants of health and address social needs to provide Black men with access to vetted, high-quality health care. Consequently, BMHC's health care model offers a useful framework for other health care organizations that are aiming to achieve health equity. The BMHC model is presented herein, highlighting strategies for other health care organizations to reach Black men and deliver trusted care. Implementing suggestions discussed in this work may lead to improved health outcomes for Black men in the United States.

Nutrition Intervention and Microbiome Modulation in the Management of Breast Cancer

Breast cancer (BC) is one of the most common cancers worldwide and a leading cause of cancer-related deaths among women. The escalating incidence of BC underscores the necessity of multi-level treatment. BC is a complex and heterogeneous disease involving many genetic, lifestyle, and environmental factors. Growing evidence suggests that nutrition intervention is an evolving effective prevention and treatment strategy for BC. In addition, the human microbiota, particularly the gut microbiota, is now widely recognized as a significant player contributing to health or disease status. It is also associated with the risk and development of BC. This review will focus on nutrition intervention in BC, including dietary patterns, bioactive compounds, and nutrients that affect BC prevention and therapeutic responses in both animal and human studies. Additionally, this paper examines the impacts of these nutrition interventions on modulating the composition and functionality of the gut microbiome, highlighting the microbiome-mediated mechanisms in BC. The combination treatment of nutrition factors and microbes is also discussed. Insights from this review paper emphasize the necessity of comprehensive BC management that focuses on the nutrition-microbiome axis.

Stereotactic Body Radiation Adoption Impacts Prostate Cancer Treatment Patterns

OBJECTIVE

To investigate stereotactic body radiation (SBRT) adoption for prostate cancer. As evidence supporting SBRT mounts, its utilization and impact relative to other prostate cancer treatments is unknown.

METHODS

We used SEER-Medicare to identify patients diagnosed with localized prostate cancer from 2008 to 2017. We then identified physician networks by identifying the primary treating physician of each patient based on primary treatment, then linking each physician to a practice. We examined trends in prostate cancer treatment between networks performing SBRT or not using chi-squared tests and logistic regression models.

RESULTS

There were 35,972 patients who received treatment for prostate cancer at 234 physician networks. Of these patients, 30,635 were treated in a non-SBRT network (n = 190), while 5337 received treatment in a SBRT network (n = 44). Patients who received care in an SBRT network were more likely to live in metropolitan areas ≥1 million (70% vs 46%, P <.001), have a higher median income >$60,000 (62% vs 42%, P <.001), and live in the northeast (35% vs 12%) or west (40% vs 38%, P <.001) compared to non-SBRT networks. In SBRT networks, more patients received IMRT (31% vs 23%), and fewer patients received prostatectomy (16% vs 23%) or active surveillance (15% vs 19%) compared to non-SBRT networks. Black men were 45% less likely to receive SBRT (OR=0.55, CI: 0.36-0.85) compared to White men.

CONCLUSION

SBRT utilization is increasing relative to other prostate cancer treatments. Prostate cancer treatment mix is different in networks that offer SBRT, and SBRT is less available to some patient groups, raising concern for novel treatment inequity.

A Retrospective Analysis of Breast Cancer Mortality among Jewish and Muslim Arab Women in Israel: The Role of Sociodemographic Factors

Breast cancer mortality rates vary across ethnic groups in Israel, where protective factors such as high fertility and breastfeeding rates may be moderated by socioeconomic factors and mammography rates. We aim to investigate disparities in breast cancer mortality between Jewish and Muslim Arab women in Israel and examine how sociodemographic variables and number of children are associated with mortality. Our retrospective follow-up study uses data from the Israeli Central Bureau of Statistics and multivariable Cox regression models, adjusting for age, number of children, country of origin, locality size, and socioeconomic status. Compared to Jewish women, Muslim Arab women exhibited lower breast cancer mortality rates. However, after adjusting for multiple sociodemographic variables, no significant differences persisted between Jewish and Muslim Arab women. Having more than three children was associated with lower mortality among Muslim Arab women but not among Jewish women. European/American origin, larger localities, and medium socioeconomic status were associated with higher mortality. Sociodemographic factors may therefore explain the disparities in breast cancer mortality between Jewish and Muslim Arab women in Israel. Targeted intervention programs that consider the unique characteristics and risk factors of different ethnic groups are needed to reduce disparities and improve outcomes.

The bench to community initiative: community-based participatory research model for translating research discoveries into community solutions

Community-based participatory research (CBPR) is an effective methodology for translating research findings from academia to community interventions. The Bench to Community Initiative (BCI), a CBPR program, builds on prior research to engage stakeholders across multiple disciplines with the goal of disseminating interventions to reduce breast cancer disparities and improve quality of life of Black communities.

Methods

The BCI program was established to understand sociocultural determinants of personal care product use, evaluate the biological impact of endocrine disrupting chemicals, and develop community interventions. The three pillars of the program include research, outreach and engagement as well as advocacy activities. The research pillar of the BCI includes development of multidisciplinary partnerships to understand the sociocultural and biological determinants of harmful chemical (e.g., endocrine disrupting chemicals) exposures from personal care products and to implement community interventions. The outreach and engagement pillar includes education and translation of research into behavioral practice. The research conducted through the initiative provides the foundation for advocacy engagement with applicable community-based organizations. Essential to the mission of the BCI is the participation of community members and trainees from underrepresented backgrounds who are affected by breast cancer disparities.

Results

Two behavioral interventions will be developed building on prior research on environmental exposures with the focus on personal care products including findings from the BCI. In person and virtual education activities include tabling at community events with do-it-yourself product demonstrations, Salon Conversations-a virtual platform used to bring awareness, education, and pilot behavior change interventions, biennial symposiums, and social media engagement. BCI's community advisory board members support activities across the three pillars, while trainees participate in personal and professional activities that enhance their skills in research translation.

Discussion

This paper highlights the three pillars of the BCI, lessons learned, testimonies from community advisory board members and trainees on the impact of the initiative, as well as BCI's mission driven approaches to achieving health equity.

Five-Year Relative Survival Rates of Women Diagnosed with Uterine Cancer by County-Level Socioeconomic Status Overall and across Histology and Race/Ethnicity

Understanding socioeconomic factors contributing to uterine cancer survival disparities is crucial, especially given the increasing incidence of uterine cancer, which disproportionately impacts racial/ethnic groups. We investigated the impact of county-level socioeconomic factors on five-year survival rates of uterine cancer overall and by histology across race/ethnicity. We included 333,013 women aged ≥ 30 years with microscopically confirmed uterine cancers (2000-2018) from the Surveillance, Epidemiology, and End Results 22 database followed through 2019. Age-standardized five-year relative survival rates were compared within race/ethnicity and histology, examining the differences across tertiles of county-level percent (%) Collapse

Trends analysis of cancer incidence, mortality, and survival for the elderly in the United States, 1975-2020

BACKGROUND

Cancer burden from the elderly has been rising largely due to the aging population. However, research on the long-term epidemiological trends in cancer of the elderly is lacking.

METHODS

Registry data of this population-based cross-sectional study were from the Surveillance, Epidemiology, and End Results (SEER) database. The study population aged 65 years or more, from geographically distinct regions. Joinpoint regression and JP Surv method were used to analyze cancer trends and survival.

RESULTS

Mortality rate during 1975-2020 decreased from 995.20 to 824.99 per 100,000 elderly persons, with an average annual decrease of 0.421% (95% CI, 0.378-0.464). While overall incidence increased with no significance. Prostate (29%) and breast (26%) cancer were the most common malignancies, respectively, in elderly males and females, and the mortality for both of the two (prostate 15%, breast 14%) ranked just behind lung and bronchus cancer, which had the highest mortality rates in males (29%) and females (23%). Many cancers showed adverse trends in the latest follow-up periods (the last period calculated by the Joinpoint method). For intrahepatic cholangiocarcinoma, incidence (male Annual Percentage Change [APC] = 7.4*; female APC = 6.7*) and mortality (male APC = 3.0*; female APC = 3.3*) increased relatively fast, and its survival was also terrible (3-year survival only 10%). Other cancers with recent increasing mortality included cancer of anus, anal canal and anorectum, retroperitoneum, pleura, peritoneum, etc. Most cancers had favorable trends of survival during the nearest follow-up period.

CONCLUSION

Against the background of overall improvement, many cancers showed adverse trends. Further research for the underlying mechanisms and targeted implements towards adverse trends is also urgent.

Housing assistance among patients with cancer: SEER-Medicare US Department of Housing and Urban Development data linkage

BACKGROUND

Lack of stable, affordable housing is an important social determinant of health. Federal housing assistance may buffer against housing vulnerabilities among low-income households, but research examining the association of housing assistance and cancer care has been limited. We introduce a new linkage of Surveillance, Epidemiology, and End Results (SEER) program-Medicare and US Department of Housing and Urban Development (HUD) administrative data.

METHODS

Individuals enrolled in HUD public and assisted housing programs between 2006 and 2021 were linked with cancer diagnoses between 2006 and 2019 identified in the SEER-Medicare data from 16 states using Match*Pro (National Institutes of Health, Bethesda, MD) probabilistic linkage software. HUD administrative data include timing and type of housing assistance as well as verified household income. Medicare administrative data are available through 2020.

RESULTS

A total of 335 490 unique individuals who received housing assistance at any time point, including 156 794 who received housing assistance around the time of their diagnosis (at least 6 months before diagnosis until 6 months after diagnosis or death), were matched to SEER-Medicare data. A total of 63 251 individuals receiving housing assistance at the time of their diagnosis were aged 66 years and older and continuously enrolled in Medicare parts A and B fee for service; 12 035 had a diagnosis of lung cancer, 8866 of breast cancer, 7261 of colorectal cancer, and 4703 of prostate cancer.

CONCLUSIONS

This novel data linkage will be available through the National Cancer Institute and can be used to explore the ways in which housing assistance is associated with cancer diagnosis, care, and outcomes, including the role of housing assistance status in potentially reducing or contributing to inequities across racialized and ethnic groups.

Development and Application of Genetic Ancestry Reconstruction Methods to Study Diversity of Patient-Derived Models in the NCI PDXNet Consortium

Precision medicine holds great promise for improving cancer outcomes. Yet, there are large inequities in the demographics of patients from whom genomic data and models, including patient-derived xenografts (PDX), are developed and for whom treatments are optimized. In this study, we developed a genetic ancestry pipeline for the Cancer Genomics Cloud, which we used to assess the diversity of models currently available in the National Cancer Institute-supported PDX Development and Trial Centers Research Network (PDXNet). We showed that there is an under-representation of models derived from patients of non-European ancestry, consistent with other cancer model resources. We discussed these findings in the context of disparities in cancer incidence and outcomes among demographic groups in the US, as well as power analyses for biomarker discovery, to highlight the immediate need for developing models from minority populations to address cancer health equity in precision medicine. Our analyses identified key priority disparity-associated cancer types for which new models should be developed.

SIGNIFICANCE

Understanding whether and how tumor genetic factors drive differences in outcomes among U.S. minority groups is critical to addressing cancer health disparities. Our findings suggest that many additional models will be necessary to understand the genome-driven sources of these disparities.

Adaption and National Validation of a Tool for Predicting Mortality from Other Causes Among Men with Nonmetastatic Prostate Cancer

BACKGROUND

An electronic health record-based tool could improve accuracy and eliminate bias in provider estimation of the risk of death from other causes among men with nonmetastatic cancer.

OBJECTIVE

To recalibrate and validate the Veterans Aging Cohort Study Charlson Comorbidity Index (VACS-CCI) to predict non-prostate cancer mortality (non-PCM) and to compare it with a tool predicting prostate cancer mortality (PCM).

DESIGN, SETTING, AND PARTICIPANTS

An observational cohort of men with biopsy-confirmed nonmetastatic prostate cancer, enrolled from 2001 to 2018 in the national US Veterans Health Administration (VA), was divided by the year of diagnosis into the development (2001-2006 and 2008-2018) and validation (2007) sets.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Mortality (all cause, non-PCM, and PCM) was evaluated. Accuracy was assessed using calibration curves and C statistic in the development, validation, and combined sets; overall; and by age (<65 and 65+ yr), race (White and Black), Hispanic ethnicity, and treatment groups.

RESULTS AND LIMITATIONS

Among 107 370 individuals, we observed 24 977 deaths (86% non-PCM). The median age was 65 yr, 4947 were Black, and 5010 were Hispanic. Compared with CCI and age alone (C statistic 0.67, 95% confidence interval [CI] 0.67-0.68), VACS-CCI demonstrated improved validated discrimination (C statistic 0.75, 95% CI 0.74-0.75 for non-PCM). The prostate cancer mortality tool also discriminated well in validation (C statistic 0.81, 95% CI 0.78-0.83). Both were well calibrated overall and within subgroups. Owing to missing data, 18 009/125 379 (14%) were excluded, and VACS-CCI should be validated outside the VA prior to outside application.

CONCLUSIONS

VACS-CCI is ready for implementation within the VA. Electronic health record-assisted calculation is feasible, improves accuracy over age and CCI alone, and could mitigate inaccuracy and bias in provider estimation.

PATIENT SUMMARY

Veterans Aging Cohort Study Charlson Comorbidity Index is ready for application within the Veterans Health Administration. Electronic health record-assisted calculation is feasible, improves accuracy over age and Charlson Comorbidity Index alone, and might help mitigate inaccuracy and bias in provider estimation of the risk of non-prostate cancer mortality.

Breast Cancer Screening among African Immigrants in the United States: An Integrative Review of Barriers, Facilitators, and Interventions

The purpose of this review was to synthesize the available literature on breast cancer-screening barriers, facilitators, and interventions among U.S. African immigrants. Following the integrative review framework and PRISMA guidelines for reporting systemic reviews, five electronic databases were searched: PubMed, CINAHL, PsycINFO, Medline, and Google Scholar. Studies were included if they were published in English language journals after 1 January 2000 and reported data on breast cancer-screening barriers, facilitators, or interventions among U.S. African immigrants. Barriers and facilitators reported by studies were descriptively examined and synthesized by two authors and classified as aligning with one of the three levels of influences based on the social-ecological model (intrapersonal, interpersonal, and community). Interventions promoting breast cancer screening were narratively summarized. Search procedures retrieved 1011 articles, with 12 meeting the criteria for inclusion in the review (6 qualitative and 6 quantitative). Intrapersonal barriers included limited awareness, fear of pain, language barriers, health concerns, transportation issues, costs, and negative past experiences. Interpersonal barriers involved modesty, spiritual beliefs, and lack of support, while community-level barriers included provider and healthcare-system challenges. Regarding facilitators, past screening experiences and health insurance were the most commonly reported intrapersonal facilitators. The only interpersonal facilitator identified was observing other women experience a breast cancer diagnosis and undergo treatment. Community-level facilitators included appointment reminders, scheduling assistance, culturally congruent interpreters, transportation to screening facilities, and patient navigators. Three articles reported outcomes of breast cancer-screening interventions. All three were pilot studies and reported increased knowledge and attitudes regarding breast cancer screening following the respective interventions. One study examined the uptake of breast cancer screening following the intervention, with results indicating an increase in screening. Findings provide a comprehensive synthesis of factors influencing breast cancer screening among African immigrants and highlight the need for future research on the topic. This review was registered with Prospero (CRD42024502826) before the initiation of search procedures.

Survival trends among patients with metastatic non-small cell lung cancer before and after the approval of immunotherapy in the United States: A Surveillance, Epidemiology, and End Results database-based study

BACKGROUND

In 2015, the US Food and Drug Administration approved nivolumab as the first immunotherapy for patients with advanced non-small cell lung cancer (NSCLC). However, population-based survival benefit studies after the introduction of immunotherapy in lung cancer are lacking. This study examined overall survival (OS) and cancer-specific survival in patients with NSCLC in the pre immunotherapy and immunotherapy eras.

METHODS

This study used the Surveillance, Epidemiology, and End Results database, which spanned 17 registries from 2000 to 2020. Two cohorts were delineated: preimmunotherapy (2010-2014) and immunotherapy (2015-2020), which coincided with nivolumab's approval.

RESULTS

This study included 191,802 patients, 90,807 in the preimmunotherapy era and 100,995 in the immunotherapy era. OS was significantly higher in the immunotherapy era, as shown by Kaplan-Meier curves (1-year OS, 40.1% vs. 33.5%; 3-year OS, 17.8% vs. 11.7%; 5-year OS, 10.7% vs. 6.8%; median OS, 8 vs. 7 months; p < .001 by log-rank test). Similarly, cancer-specific survival improved in the immunotherapy era (1-year survival, 44.0% vs. 36.8%; 3-year survival, 21.7% vs. 14.4%; 5-year survival, 14.3% vs. 9.0%; median OS, 10 vs. 8 months; p < .001 by log-rank test). Survival rates were significantly better in the immunotherapy era, as confirmed by multivariate analysis with a Cox proportional hazards model after adjusting for age, sex, race, income, and geographical area (adjusted hazard ratio, 0.830; 95% CI, 0.821-0.840; p < .001).

CONCLUSIONS

In summary, the survival rate of patients with metastatic NSCLC has improved since the introduction of immunotherapy.
