Although black and white patients with breast cancer tend to see different surgeons and oncologists, this distribution does not contribute to disparities in BRCA1/2 testing. Instead, residual racial differences in testing after accounting for patient and physician characteristics are largely attributable to differences in physician recommendations. Efforts to address these disparities should focus on ensuring equity in testing recommendations.

Evidence shows that Black women diagnosed with breast cancer are substantially less likely to undergo BRCA testing and other multipanel genetic testing compared to White women, despite having a higher incidence of early‐age onset breast cancer and triple‐negative breast cancer (TNBC). Our study identifies predictors of BRCA testing among Black women treated for breast cancer and examines differences between BRCA testers and nontesters. We conducted an analysis of 945 Black women ages 18–64 diagnosed with localized or regional‐stage invasive breast cancer in Pennsylvania and Florida between 2007 and 2009. Logistic regression was used to identify predictors of BRCA 1/2 testing. Few (27%) (n = 252) of the participants reported having BRCA testing. In the multivariate analysis, we found that perceived benefits of BRCA testing (predisposing factor) ([OR], 1.16; 95% CI: 1.11–1.21; P < 0.001), income (enabling factor) ([OR], 2.10; 95% CI: 1.16–3.80; p = 0.014), and BRCA mutation risk category (need factor) ([OR], 3.78; 95% CI: 2.31–6.19; P < 0.001) predicted BRCA testing. These results suggest that interventions to reduce disparities in BRCA testing should focus on identifying patients with high risk of mutation, increasing patient understanding of the benefits of BRCA testing, and removing financial and other administrative barriers to genetic testing.

BackgroundTo assess mentorship experiences among the faculty of a large academic department of medicine and to examine how those experiences relate to academic advancement and job satisfaction.MethodsAmong faculty members in the Massachusetts General Hospital Department of Medicine, we assessed personal and professional characteristics as well as job satisfaction and examined their relationship with two mentorship dimensions: (1) currently have a mentor and (2) role as a mentor. We also developed a mentorship quality score and examined the relationship of each mentorship variable to academic advancement and job satisfaction.Results553/988 (56.0%) of eligible participants responded. 64.9% reported currently having a mentor, of whom 21.3% provided their mentor a low quality score; 66.6% reported serving as a mentor to others. Faculty with a current mentor had a 3.50-fold increased odds of serving as a mentor to others (OR 3.50, 95% CI 1.84–6.67, p < 0.001). Faculty who reported their mentorship as high quality had a decreased likelihood of being stalled in rank (OR 0.28, 95% CI: 0.10–0.78, p = 0.02) and an increased likelihood of high job satisfaction (OR 3.91, 95% CI 1.77–8.63, p < 0.001) compared with those who reported their mentorship of low quality; further, having a low mentorship score had a similar relationship to job satisfaction as not having a mentor.ConclusionsA majority of faculty survey respondents had mentorship, though not all of it of high caliber. Because quality mentorship significantly and substantially impacts both academic progress and job satisfaction, efforts devoted to improve the adoption and the quality of mentorship should be prioritized.Electronic supplementary materialThe online version of this article (10.1186/s12909-018-1191-5) contains supplementary material, which is available to authorized users.

Contralateral prophylactic mastectomy use has increased over the past decades among women with early-stage breast cancer. Racial differences in contralateral prophylactic mastectomy use are well described, but with unclear causes. This study examined contralateral prophylactic mastectomy use among black and white women and the contribution of differences in perceived risk to differences in use. We surveyed women diagnosed with early-stage unilateral breast cancer between ages 41–64 in Pennsylvania and Florida between 2007–2009 to collect data on breast cancer treatment, family history, education, income, insurance, and perceived risk. Clinical factors—age,stage at diagnosis, receptor status—were obtained from cancer registries. The relationships between patient factors and contralateral prophylactic mastectomy were assessed using logistic regression. The interaction between race and contralateral prophylactic mastectomy on the perceived risk of second breast cancers was tested using linear regression. Of 2182 study participants, 18% of whites underwent contralateral prophylactic mastectomy compared with 10% of blacks (p < 0.001). The racial difference remained after adjustment for clinical factors and family history (odds ratio = 2.32, 95% confidence interval 1.76–3.06, p < 0.001). The association between contralateral prophylactic mastectomy and a reduction in the perceived risk of second breast cancers was significantly smaller for blacks than whites. Blacks were less likely than whites to undergo contralateral prophylactic mastectomy even after adjustment for clinical factors. This racial difference in use may relate to the smaller impact of contralateral prophylactic mastectomy on the perceived risk of second breast cancers among blacks than among whites. Future research is needed to understand the overall impact of perceived risk on decisions about contralateral prophylactic mastectomy and how that may explain racial differences in use.
