Building a comprehensive mentoring academy for schools of health.
Formal mentoring programs are increasingly recognized as critical for faculty career development. We describe a mentoring academy (MA) developed for faculty across tracks (i.e., researchers, clinicians, educators) within a "school of health" encompassing schools of medicine and nursing. The program is anchored dually in a clinical and translational science center and a school of health. The structure includes the involvement of departmental and center mentoring directors to achieve widespread uptake and oversight. A fundamental resource provided by the MA includes providing workshops to enhance mentoring skills. Initiatives for junior faculty emphasize establishing and maintaining strong mentoring relationships and implementing individual development plans (IDPs) for career planning. We present self-report data on competency improvement from mentor workshops and data on resources and barriers identified by junior faculty (n = 222) in their IDPs. Mentors reported statistically significantly improved mentoring competency after workshop participation. Junior faculty most frequently identified mentors (61%) and collaborators (23%) as resources for goal attainment. Top barriers included insufficient time and time-management issues (57%), funding limitations (18%), work-life balance issues (18%), including inadequate time for self-care and career development activities. Our MA can serve as a model and roadmap for providing resources to faculty across traditional tracks within medical schools
Next-generation transcriptome sequencing of the premenopausal breast epithelium using specimens from a normal human breast tissue bank
Introduction
Our efforts to prevent and treat breast cancer are significantly impeded by a lack of knowledge of the biology and developmental genetics of the normal mammary gland. In order to provide the specimens that will facilitate such an understanding, The Susan G. Komen for the Cure Tissue Bank at the IU Simon Cancer Center (KTB) was established. The KTB is, to our knowledge, the only biorepository in the world prospectively established to collect normal, healthy breast tissue from volunteer donors. As a first initiative toward a molecular understanding of the biology and developmental genetics of the normal mammary gland, the effect of the menstrual cycle and hormonal contraceptives on DNA expression in the normal breast epithelium was examined.
Methods
Using normal breast tissue from 20 premenopausal donors to KTB, the changes in the mRNA of the normal breast epithelium as a function of phase of the menstrual cycle and hormonal contraception were assayed using next-generation whole transcriptome sequencing (RNA-Seq).
Results
In total, 255 genes representing 1.4% of all genes were deemed to have statistically significant differential expression between the two phases of the menstrual cycle. The overwhelming majority (221; 87%) of the genes have higher expression during the luteal phase. These data provide important insights into the processes occurring during each phase of the menstrual cycle. There was only a single gene significantly differentially expressed when comparing the epithelium of women using hormonal contraception to those in the luteal phase.
Conclusions
We have taken advantage of a unique research resource, the KTB, to complete the first-ever next-generation transcriptome sequencing of the epithelial compartment of 20 normal human breast specimens. This work has produced a comprehensive catalog of the differences in the expression of protein-coding genes as a function of the phase of the menstrual cycle. These data constitute the beginning of a reference data set of the normal mammary gland, which can be consulted for comparison with data developed from malignant specimens, or to mine the effects of the hormonal flux that occurs during the menstrual cycle

Breast Conserving Surgery Compared With Mastectomy in Male Breast Cancer: A Brief Systematic Review.
The surgical guidelines for male breast cancer (MBC) have been largely guided by female-predominant clinical trials. Because no clinical trial has been conducted to examine the surgical treatment of MBC, we performed a systematic review comparing the survival of patients with MBC who had undergone breast conserving surgery (BCS) and those who had undergone mastectomy and evaluated the patients' radiotherapy compliance after BCS. We performed a systematic search of electronic databases to find MBC cohort studies that had reported ≥ 1 survival outcome (disease-free survival [DFS], disease-specific survival [DSS], or overall survival [OS]) stratified by surgical treatment (BCS and/or mastectomy) and/or radiotherapy compliance with BCS. A total of 1 prospective and 9 retrospective cohort studies were included, with the number of patients ranging from 7 to 6039. Of the BCS patients, compliance with postoperative radiotherapy was low (range, 27%-46%), with the exception of 1 single-institution prospective study that reported 86% compliance (6 of 7 patients). The pooled estimate for all patients with MBC was 83% (95% confidence interval [CI], 78%-88%) for 5-year DSS and 66% (95% CI, 63%-70%) for 5-year OS. Most studies reported no differences in DFS, DSS, or OS for BCS and mastectomy. BCS is a reasonable treatment approach for MBC because it was associated with oncologic outcomes similar to those with mastectomy. However, the low rates of radiotherapy compliance among male patients who underwent BCS is concerning and highlights the importance of shared decision-making with patients with MBC when selecting a surgical treatment strategy

Secondary Breast Cancer Sociodemographic Characteristics and Survival by Age Group.
BackgroundSecondary cancers account for 16% of all new cancer diagnoses, with breast cancer (BC) the most common secondary cancer. We have shown that secondary BC has unique characteristics and decreased survival compared with primary BC in adolescent and young adults (AYA; 15-39 years old). However, older BC populations are less well studied.MethodsFemales (age ≥ 15 years) diagnosed with primary BC during 1991-2015 (n = 377,167) and enrolled in the California Cancer Registry were compared with those with secondary BC (n = 37,625) by age (15-39, 40-64, ≥ 65 years). We examined BC-specific survival (BCSS) accounting for other causes of death as a competing risk using multivariable Cox proportional hazards regression.ResultsMost secondary BC patients were of older age (15-39, n = 777; 40-64, n = 15,848; ≥ 65, n = 21,000). Compared with primary BC treatment, secondary BCs were more often treated with mastectomy and less often with chemotherapy and/or radiation. BCSS was shorter in secondary BC patients than primary BC patients, but the survival difference between secondary and primary BC diminished with age [15-39 hazard ratio (HR): 2.09, 95% confidence interval (CI) 1.83-2.39; 40-64 HR: 1.51; 95% CI 1.44-1.58; ≥ 65 HR: 1.14; 95% CI 1.10-1.19]. Survival differences were most pronounced in women with hormone receptor positive disease and Hispanic and Asian/Pacific Islanders 40-64 years of age.ConclusionsWhen BC is diagnosed following a prior cancer of any organ site, BCSS is worse than when compared with patients for whom BC is the primary diagnosis, suggesting that we may need to tailor our treatments for women with secondary BC

Survival After Contralateral Secondary Breast Cancer by Age Group in California
PurposeBreast cancer (BC) is the most common secondary cancer and has poorer survival than primary BC (pBC) after any prior malignancy. For BC survivors, developing a contralateral secondary BC (CSBC) is the most frequent second-cancer event and is currently treated similarly to pBC. Identifying survival differences between pBC and CSBC could influence future counseling and treatments for patients with CSBC.MethodsWomen (≥15 years) diagnosed with pBC from 1991 to 2015 in the California Cancer Registry (n = 377,176) were compared with those with CSBC (n = 15,586) by age group (15-39 years, n = 406; 40-64 years, n = 6814; ≥ 65 years, n = 8366). Multivariable logistic regression models assessed factors associated with CSBC. Multivariable Cox proportional hazards regression models assessed BC-specific survival (BCSS), while accounting for the competing risk of death.ResultsAcross all ages, CSBC patients were more likely to have smaller tumors (T2 vs. T1a; 15-39 yeras: OR 0.25, CI 0.16-0.38; 40-64 years: OR 0.41, CI 0.37-0.45; ≥ 65 years: OR 0.46, CI 0.42-0.51) and lymph node-negative disease (positive vs. negative; 15-39 years: OR 0.86, CI 0.69-1.08; 40-64 years: OR 0.88, CI 0.83-0.93; ≥ 65 years: OR 0.89, CI 0.84-0.94). Additionally, CSBC was associated with worse survival compared with pBC across all ages (15-39 years: HR 2.73, CI 2.30-3.25; 40-64 years: HR 2.13, CI 2.01-2.26; ≥ 65 years: HR 1.52, CI 1.43-1.61).ConclusionBCSS is worse among all women diagnosed with CSBC compared with pBC, with the strongest impact seen in adolescent and young adult women. Worse survival after CSBC, despite associations with smaller tumors and lymph node negativity, suggests that CSBC may need eventual treatment reconsideration
