AbstractYoung breast cancer (BC) patients carrying a germline BRCA pathogenic variant (mBRCA) have similar outcomes as non-carriers. However, the impact of the type of gene (BRCA1 vs. BRCA2) and hormone receptor status (positive [HR+] vs. negative [HR−]) on clinical behavior and outcomes of mBRCA BC remains largely unknown. This is an international, multicenter, hospital-based, retrospective cohort study that included mBRCA patients diagnosed, between January 2000 and December 2012, with stage I–III invasive early BC at age ≤40 years. From 30 centers worldwide, 1236 young mBRCA BC patients were included. Among 808 and 428 patients with mBRCA1 or mBRCA2, 191 (23.6%) and 356 (83.2%) had HR+tumors, respectively (P < 0.001). Median follow-up was 7.9 years. Second primary BC (P = 0.009) and non-BC malignancies (P = 0.02) were more frequent among mBRCA1 patients while distant recurrences were less frequent (P = 0.02). Irrespective of hormone receptor status, mBRCA1 patients had worse disease-free survival (DFS; adjusted HR = 0.76, 95% CI = 0.60–0.96), with no difference in distant recurrence-free interval (DRFI) and overall survival (OS). Patients with HR+ disease had more frequent distant recurrences (P < 0.001) and less frequent second primary malignancies (BC: P = 0.005; non-BC: P = 0.18). No differences in DFS and OS were observed according to hormone receptor status, with a tendency for worse DRFI (adjusted HR = 1.39, 95% CI = 0.94–2.05) in patients with HR+ BC. Type of mBRCA gene and hormone receptor status strongly impact BC clinical behavior and outcomes in mBRCA young patients. These results provide important information for patients’ counseling on treatment, prevention, and surveillance strategies.

Abstract Background The Oncotype DX 21-gene Recurrence Score is predictive of adjuvant chemotherapy benefit for women with early-stage, estrogen receptor (ER)-positive, HER2-negative breast cancer. In premenopausal women, fluctuations in estrogen and progesterone during the menstrual cycle impact gene expression in hormone-responsive cancers. However, the extent to which menstrual cycling affects the Oncotype DX 21-gene signature remains unclear. Here, we investigate the impact of ovarian cycle stage on the 21-gene signature using a naturally cycling mouse model of breast cancer. Methods ER-positive mammary tumours were dissected from naturally cycling Mmtv-Pymt mice at either the estrus or diestrus phase of the ovarian cycle. The Oncotype DX 21-gene signature was assessed through quantitative real time-PCR, and a 21-gene experimental recurrence score analogous to the Oncotype DX Recurrence Score was calculated. Results Tumours collected at diestrus exhibited significant differences in expression of 6 Oncotype DX signature genes (Ki67, Ccnb1, Esr1, Erbb2, Grb7, Bag1; p ≤ 0.05) and a significant increase in 21-gene recurrence score (21.8 ± 2.4; mean ± SEM) compared to tumours dissected at estrus (15.5 ± 1.9; p = 0.03). Clustering analysis revealed a subgroup of tumours collected at diestrus characterised by increased expression of proliferation- (p < 0.001) and invasion-group (p = 0.01) genes, and increased 21-gene recurrence score (p = 0.01). No correlation between ER, PR, HER2, and KI67 protein abundance measured by Western blot and abundance of mRNA for the corresponding gene was observed, suggesting that gene expression is more susceptible to hormone-induced fluctuation compared to protein expression. Conclusions Ovarian cycle stage at the time of tissue collection critically affects the 21-gene signature in Mmtv-Pymt murine mammary tumours. Further studies are required to determine whether Oncotype DX Recurrence Scores in women are similarly affected by menstrual cycle stage.

Purpose The majority of women with breast cancer from low-income countries, including Ethiopia, present with advanced clinical stage disease, which results in limited and difficult therapeutic options and high mortality rates. In Ethiopia, breast cancer is the most common cancer. We found that 70% of breast cancer cases in Ethiopia are hormone receptor positive. Endocrine therapy is one of the treatment options recommended for breast cancer but that is highly underutilized in the country. Recommendations on interventions to improve uptake and adherence to therapy exist, but studies that have assessed the feasibility of implementing these are limited. Our study (n = 107) in rural Ethiopia revealed an estimated 53% 2-year survival rate in patients who underwent surgery only. In our pilot study, of 51 eligible patients 26 initiated therapy and one half of those adhered after 1 year. Our study aims to evaluate the effectiveness of using a trained breast nurse navigator to improve patient adherence to tamoxifen therapy among patients with breast cancer in rural Ethiopia. Methods A cluster randomized intervention trial is being carried out in rural hospitals in southwestern Ethiopia from February 2018 to June 2019. We use hospitals in clusters as the units of randomization. The sample size includes four per intervention arm and control arm, with each cluster comprised of approximately 15 patients. Before intervention, all patients in the hospitals will receive tamoxifen therapy free of charge. Hormone receptor status of the breast cancer specimen will be determined before the initiation of therapy or throughout the course of therapy. The primary outcome of this trial is adherence to endocrine therapy on the basis of objective and subjective measures. Data will be collected with a prospective repeated measures approach. Analysis will be based on an intention-to-treat principle. Results The trial aims to provide evidence on the effectiveness of the breast nurse intervention to improve adherence to long-term endocrine therapy and answer the following research question: does the nursing intervention improve long-term treatment adherence by patients to endocrine therapy compared with those who receive usual care services? Conclusion These data are essential to maximize the impact of trained nurse-based interventions on adherence to endocrine (tamoxifen) therapy among patients with breast cancer on follow-up.

Abstract Introduction Oestrogen receptor beta (ER-β) is abundantly expressed in breast cancer (BC), but its impact on neoadjuvant chemotherapy outcome is unknown. Patients and Methods Patients treated in the neoadjuvant GeparTrio trial with available tissue for immunohistochemical analyses were included. Nuclear ER-β expression was correlated with clinico-pathologic characteristics. The impact of its expression on pathological complete response (pCR [ypT0/ypN0]) and survival was determined. Results Samples of 570 patients were available. Low nuclear ER-β expression (IRS < 9) was observed in 48.4% of hormone receptor positive and 58.6% of hormone receptor negative tumours. Low nuclear ER-β expression was associated with higher pCR rates compared to high nuclear ER-β expression (16.1% vs. 4.7%, p = 0.026). Low ER-β expression was no independent predictor of pCR in multivariate analyses. Disease-free and overall survival were not statistically different between patients with high and low nuclear ER-β expression. Triple-negative BCs showed low nuclear ER-β expression in 57.7%, and pCR rates were 27.1% and 0% (p = 0.23) in low and high ER-β expressing tumours, respectively. Conclusion Low ER-β expression is associated with improved pCR rates in univariate analyses. However multivariate analyses and survival analyses do not indicate an impact of ER-β on survival in patients undergoing neoadjuvant chemotherapy. Further examination of ER-β as predictor for endocrine therapy might be of value.

OBJECTIVES: to compare the impact of mastectomy and conservative surgery on the quality of life of patients with breast cancer. METHODS: an assessment was made of the quality of life of patients undergoing mastectomy or segmentary mastectomy, at the Pouso Alegre Clinical Hospital, in the Brazilian State of Minas Gerais, using SF-36. The patients were grouped by age (<50 years and >50 years) and years of schooling (<8 years and >8 years). The Mann-Whitney test was used to compare the groups with regard to the age and schooling domains of SF-36. RESULTS: a significant difference between the two groups was found in the domains of "physical functioning" (p=0.04) and "pain" (p=0.01): with the patients undergoing a mastectomy registering the worst scores. Young patients who had undergone a mastectomy displayed the worst quality of life in terms of "physical functioning" (p=0.03), "pain" (p=0.01) and "social functioning" (p=0.01); those undergoing conservative surgery aged over 50 years scored worst on "role emotional" (p=0.05). Patients undergoing a mastectomy with lower levels of schooling scored lower in "physical functioning" (p=0.01), "role physical" (p=0.05) and "pain" (p=0.05). Among those who had attended school for more than eight years, those having undergone a mastectomy scored less in the "pain" domain (p=0.04). CONCLUSIONS: patients who had undergone a mastectomy had worse results in the physical component of the evaluation of quality of life and this negative impact was more strongly felt among younger patients and those with lower levels of schooling.
