Impact of molecular subtype and race on HR+, HER2- breast cancer survival.

Breast Cancer Res Treat 2021 Oct 31;189(3):845-852. Epub 2021 Jul 31.

Vanderbilt University Medical Center (VUMC)/Vanderbilt-Ingram Cancer Center (VICC), 2220 Pierce Ave. 777 PRB, Nashville, TN, 37232, USA.

Purpose: There is an urgent need to understand the biological factors contributing to the racial survival disparity among women with hormone receptor-positive (HR+), HER2- breast cancer. In this study, we examined the impact of PAM50 subtype on 10-year mortality rate in women with HR+, HER2- breast cancer by race.

Methods: Women with localized, HR+, HER2- breast cancer diagnosed between 2002 and 2012 from two population-based cohorts were evaluated. Archival tumors were obtained and classified by PAM50 into four molecular subtypes (i.e., luminal A, luminal B, HER2-enriched, and basal-like). The molecular subtypes within HR+, HER2- breast cancers and corresponding 10-year mortality rate were compared between Black and Non-Hispanic White (NHW) women using Cox proportional hazard ratios and survival analysis, adjusting for covariates.

Results: In this study, 318 women with localized, HR+, HER2- breast cancer were included-227 Black (71%) and 91 NHW (29%). Young Black women (age ≤ 50) had the highest proportion of HR+, non-luminal A tumors (47%), compared to young NHW (10%), older Black women (31%), and older NHW (30%). Overall, women with HR+, non-luminal A subtypes had a higher 10-year mortality rate compared to HR+, luminal A subtypes after adjustment for age, stage, and income (HR 4.21 for Blacks, 95% CI 1.74-10.18 and HR 3.44 for NHW, 95% CI 1.31-9.03). Among HR+, non-luminal A subtypes there was, however, no significant racial difference in 10-yr mortality observed (Black vs. NHW: HR 1.23, 95% CI 0.58-2.58).

Conclusion: Molecular subtype classification highlights racial disparities in PAM50 subtype distribution among women with HR+, HER2- breast cancer. Among women with HR+, HER2- breast cancer, racial survival disparities are ameliorated after adjusting for molecular subtype.

Disparities in BRCA counseling across providers in a diverse population of young breast cancer survivors.

Genet Med 2020 06 18;22(6):1088-1093. Epub 2020 Feb 18.

Vanderbilt University Medical Center, Nashville, TN, USA.

Purpose: All women diagnosed with breast cancer (BC) ≤age 50 should be referred for genetic counseling (GC) and testing. We sought to compare differences in provider practices and access across a racially and ethnically diverse population of young BC survivors.

Methods: A registry-based sample of women diagnosed with invasive BC ≤age 50 from 2009 to 2012 was recruited through the Florida Cancer Registry, and completed a questionnaire and medical record release. Differences were compared across those tested with or without the involvement of a board-certified or credentialed genetics health professional (GHP) in (1) clinical and demographic variables and (2) pretest GC elements.

Results: Of 1622 participants, there were 440 Blacks, 285 Hispanics, and 897 Non-Hispanic Whites. Of 831 participants with medical record verification of testing provider, 170 (20%) had documentation of GHP involvement. Among the 613 who recalled a pretest discussion and had GC elements collected, those with GHP involvement were significantly more likely to recall the seven recognized GC elements.

Conclusion: GHP involvement was associated with adherence to nationally recommended best practices. With the expanding importance of identifying inherited cancers, it is critical to ensure equitable access to best practices across all populations.

An exploratory investigation of geographic disparities of stroke prevalence in Florida using circular and flexible spatial scan statistics.

PLoS One 2019 30;14(8):e0218708. Epub 2019 Aug 30.

Biomedical and Diagnostic Sciences, College of Veterinary Medicine, The University of Tennessee, Knoxville, Tennessee, United States of America.

Background: Stroke is a major public health concern due to the morbidity and mortality associated with it. Identifying geographic areas with high stroke prevalence is important for informing public health interventions. Therefore, the objective of this study was to investigate geographic disparities and identify geographic hotspots of stroke prevalence in Florida.

Materials And Methods: County-level stroke prevalence data for 2013 were obtained from the Florida Department of Health's Behavioral Risk Factor Surveillance System (BRFSS). Geographic clusters of stroke prevalence were investigated using the Kulldorff's circular spatial scan statistics (CSSS) and Tango's flexible spatial scan statistics (FSSS) under Poisson model assumption. Exact McNemar's test was used to compare the proportion of cluster counties identified by each of the two methods. Both Cohen's Kappa and bias adjusted Kappa were computed to assess the level of agreement between CSSS and FSSS methods of cluster detection. Goodness-of-fit of the models were compared using Cluster Information Criterion. Identified clusters and selected stroke risk factors were mapped.

Results: Overall, 3.7% of adults in Florida reported that they had been told by a healthcare professional that they had suffered a stroke. Both CSSS and FSSS methods identified significant high prevalence stroke spatial clusters. However, clusters identified using CSSS tended to be larger than those identified using FSSS. The FSSS had a better fit than the CSSS. Most of the identified clusters are explainable by the prevalence distributions of the known risk factors assessed.

Conclusions: Geographic disparities of stroke risk exists in Florida with some counties having significant hotspots of high stroke prevalence. This information is important in guiding future research and control efforts to address the problem. Kulldorff's CSSS and Tango's FSSS are complementary to each other and should be used together to provide a more complete picture of the distributions of spatial clusters of health outcomes.

Anxiety Among Inpatients With Cancer: Findings From a Hospital-Based Cross-Sectional Study in Vietnam.

Cancer Control 2019 Jan-Dec;26(1):1073274819864641

Anxiety, a condition which is commonly found in patients with cancer, has negative impacts on their quality of life and treatment outcome. This study aimed to determine the level of anxiety in patients with cancer and explore sociodemographic, disease-related, and hospital-related factors associated with anxiety in those patients. A cross-sectional study was conducted on 510 inpatients with cancer at Thanh Hoa Oncology Hospital, Vietnam. Data were collected from self-administered questionnaire forms on hospital depression anxiety-A, interviews with patients, and patient medical records. The univariate and multivariate linear regression analyses were performed using STATA ver. 14.0. Our finding that the patients' mean anxiety score (standard deviation) was 7.22 (3.8); 27.6% of the patients had an anxiety score between 8 and 10 points, and 15.5% had an anxiety score of ≥11 points. In the multivariate model, in more advanced stages of cancer, and patients with metastasis were more likely to have higher levels of anxiety than those who presented no sign of metastasis. The longer the patients had cancer, the less anxious they became. Lower levels of anxiety were observed in patients who stated that hospital facilities were adequate or had trust in health workers. Patients with cancer need to be provided with psychological support in the early stage of cancer detection and when metastases form. A strong patient-health-care provider relationship after diagnosis may help reduce distress among patients with cancer with higher levels of medical mistrust.
