Male breast cancer is an uncommon disease accounting for only 1% of all breast cancers. We present the evaluation, treatment and outcome of male patients seen with breast cancer in our institution. Male patients that had histological diagnosis of breast cancer from 2001 to 2010 were retrospectively evaluated. After evaluation patients were treated with modified radical mastectomy. Combination chemotherapy was given to patients with positive axillary lymph nodes. Radiotherapy and hormonal therapy were also employed. There were 57 male patients with breast cancer which accounted for 9% of all breast cancers seen during the study period. Their mean age was 59 ± 2.3 years. The mean tumor diameter was 13 ± 2.5 cm. Fifty three (93%) patients presented with advanced disease including 15 with distant metastasis. Four patients with stage II disease were treated with modified radical mastectomy, chemotherapy and tamoxifen. Of the 30 patients with sage III disease that had modified radical mastectomy, complete axillary clearance and tumor free margins were achieved in 25. Overall 21 (36.8%) patients were tumor free at one year. Overall 5-year survival was 22.8%. In conclusion, male patients with breast cancer present with advanced disease which is associated with poor outcome of treatment.

Male breast cancer is a rare but important condition accounting for only 1% of breast cancer worldwide and less than 1% of all male malignancies. Occult male breast cancer is an extremely rare type of male breast cancer that manifests as axillary metastases without an identifiable breast lesion. We report a case of triple-negative occult male breast cancer who underwent modified radical mastectomy.

Introduction: Male breast cancer is an uncommon entity. Due to the scarce numbers, treatment protocolshave largely been extrapolated from available evidence for female breast cancers.Methods: We analysed the clinicopathological features and survival outcomes for male breast cancer patients treated at our institute between January 2010 and June 2016.Results: Of the 5534 women treated at our institute, we screened 40 male breast cancers of whom 33 had available follow up data and were included in the present analysis. Male breast cancer constituted 0.7% of all breast cancers. The median age was 60 years and the median tumor size was 3cm with 66% of patients having nodal disease at presentation. Invasive ductal carcinoma was the most common histology and 97% were hormone receptor positive. Most of the patients (87.8%) underwent an upfront modified radical mastectomy. With a median follow up of 36 months, 10 patients experienced recurrences all of which were distant metastasis (3 to the bone, 1 to the brain, and 6 had visceral metastasis). Of these, 7 patients succumbed to the disease. The 3-year overall survival was 78.7 %.Conclusion: Male breast cancer is a rare clinical entity and current treatment guidelines follow those for women. Due to the lack of awareness, men often present to clinics at an advanced stage. Social support targeted at improving awareness and access to treatment could improve outcomes in this cohort.

Male breast cancer is a rare clinical entity accounting for approximately 1 per cent of all breast cancers. The present study investigated changes in patient characteristics, disease patterns, treatment, and outcomes over a 30-year period. A retrospective chart review was performed on male breast cancer patients treated between 1975 and 2005 at Eastern Virginia Medical School, Norfolk, VA. Demographic, pathologic, treatment, and survival information was collected. To facilitate comparison of trends, the patients were divided into two groups: Cohort A (1972–1991, previously reported) and Cohort B (1992–2005). Both cohorts included 28 male patients. Comparing the cohorts, no statistical differences were noted in median age, ethnicity, presenting symptoms, or progesterone receptor status. In Cohort A, 70 per cent of patients were estrogen receptor positive, compared with 100 per cent of Cohort B ( P = 0.02). Her2/neu was positive in three of five patients in Cohort B. There was a trend toward more conservative surgery, with no radical mastectomy or orchiectomy performed in Cohort B. Only two patients had sentinel lymph node mapping, both from Cohort B. Infiltrating ductal carcinoma was more prevalent in Cohort B ( P = 0.04). For Cohort A and B, 5-year survival was 43 per cent and 51 per cent, respectively, which was not statistically significant. For male breast cancer, radical mastectomy is no longer a common treatment modality. Male breast cancer of today is more hormonally responsive which may have important implications for therapy. Survival has not significantly improved over the previous 30 years. Compilation of multi-institutional data of male breast cancer is needed to advance the treatment of this uncommon disease.

Background: Male breast cancer (MBC) is an uncommon malignancy accounting for <1% of all cancers in men and <1 % of overall breast cancer cases. Although there are many similarities between MBC and female breast cancer (FBC), they are not identical in clinical behaviour. There is need to understand the exact biological behavior of MBC.Methods: A retrospective observational study was done at State Cancer Institute, IGIMS, Patna which included all MBC patients registered during a 5-year study period (January 2016 to April 2021). 16 consecutive cases of MBC were identified and their detailed clinicopathological profile was analyzed.Results: MBC accounted for 1.10% of the total breast cancer cases. The median age of presentation was 58 years. Most common presentation was lump. Invasive ductal carcinoma (IDC) was most common histology. Majority of the patient presented to us in advanced stage. Estrogen receptor (ER)/progesterone receptor (PR) status was found to be positive in 12 patients. HER-2/neu receptor was positive in 4 patients. 2 patients had triple negative disease (TNBC) status. Surgery in the form of modified radical mastectomy (MRM) was done in 10 patients. All patients received adjuvant therapy as per NCCN guidelines.Conclusions: MBC is rare disease presenting at a relatively early age in Indian male patients. Most of them have positive ER/PR status. As outcomes have not improved comparatively, there is a need to evolve separate guidelines for MBC.

AbstractMale breast cancer (BCa) is a rare disease accounting for less than 1% of all breast cancers and 1% of all cancers in males. The clinical management is largely extrapolated from female BCa. Several multigene assays are increasingly used to guide clinical treatment decisions in female BCa, however, there are limited data on the utility of these tests in male BCa. Here we present the gene expression results of 381 M0, ER+ve, HER2-ve male BCa patients enrolled in the Part 1 (retrospective analysis) of the International Male Breast Cancer Program. Using a custom NanoString™ panel comprised of the genes from the commercial risk tests Prosigna®, OncotypeDX®, and MammaPrint®, risk scores and intrinsic subtyping data were generated to recapitulate the commercial tests as described by us previously. We also examined the prognostic value of other risk scores such as the Genomic Grade Index (GGI), IHC4-mRNA and our prognostic 95-gene signature. In this sample set of male BCa, we demonstrated prognostic utility on univariate analysis. Across all signatures, patients whose samples were identified as low-risk experienced better outcomes than intermediate-risk, with those classed as high risk experiencing the poorest outcomes. As seen with female BCa, the concordance between tests was poor, with C-index values ranging from 40.3% to 78.2% and Kappa values ranging from 0.17 to 0.58. To our knowledge, this is the largest study of male breast cancers assayed to generate risk scores of the current commercial and academic risk tests demonstrating comparable clinical utility to female BCa.

Abstract Context.—The rate of male breast cancer is a small fraction of that observed in females, thus severely limiting our understanding of the pathogenesis of this condition. It remains unclear whether the biological behavior and tumor progression associated with male breast cancer parallel that of the female form. Objectives.—To evaluate the immunohistochemical profile of male breast carcinomas and to compare this profile with that of stage-matched female breast cancers. Design.—Seventy-five cases of primary male breast cancer were identified using the records of the Saskatchewan Cancer Foundation over a period of 26 years (1970–1996). Fifty-nine of these cases had formalin-fixed, paraffin-embedded tissue blocks available for the purposes of this study. All cases were reviewed and a standardized modified Bloom-Richardson grading criterion was applied. Estrogen receptor status, progesterone receptor status, c-Erb-B2 expression, p53 expression, and Bcl-2 expression were evaluated by immunohistochemistry. Results from 240 consecutive cases of stage-matched female breast cancers analyzed in the same laboratory were used as a standard set for comparison. Results.—Male breast cancers tended to be high grade (85% grade 3) in comparison with the female breast cancers (50% grade 3). In descriptive analysis across all stages of disease, male carcinomas were more frequently estrogen receptor positive (81% vs 69%) than their female counterparts. Despite their high grade, they were less likely to overexpress p53 (9% vs 28%) and Erb-B2 (5% vs 17%) than the female counterparts. There was no significant difference in either progesterone receptor (63% vs 56%) or Bcl-2 (79% vs 76%) overexpression. Stratified analysis by stage-matched controls showed no statistically significant differences among the men and women with stage I disease. However, in stage II–matched samples, statistically significant differences were observed between the 2 groups. The male cancers were more likely to overexpress estrogen receptor (81.6% vs 64.4%, P = .04), progesterone receptor (71.1% vs 47.5%, P = .01), and Bcl-2 (78.9% vs 69.4%, P = .20). They also showed statistically significant lower expression of p53 (7.9% vs 36.3%, P = .001) and Erb-B2 (5.3% vs 23.8% P = .01). Conclusion.—Male breast cancers display distinct immunophenotypic differences from those occurring in women, implying a different pathogenesis in the evolution and progression of this disease. Such differences may play key roles in therapeutic management, warranting different treatment strategies in comparison to female breast cancers.
