Male Breast Cancer: The Three Decades' Experience of a Tertiary Care Hospital in a Lower-Middle Income Country.

Abstract

IntroductionMale breast cancer is uncommon and managed on the guidelines of female breast cancer due to tumor rarity. We sought to identify the incidence, clinicopathological features, and survival of all male breast cancer patients managed in our hospital.MethodsA retrospective cross-sectional study was conducted at Aga Khan University Hospital (AKUH), Karachi, Pakistan, from January 1986 to December 2018. Demographic data, treatment records, and follow-up data of all male breast cancer patients who were treated at AKUH was reviewed.ResultsThirty-eight out of 42 patients who presented over a period of 32 years were included. The mean age was 63 years. The most common tumor type and subtype were invasive ductal carcinoma (89.5%) and luminal A (73.7%), respectively. The majority (36.8%) of the patients presented at stage III. Among 30 (78.9%) patients who underwent surgery, mastectomy was performed in 30 (78.9%), upfront axillary clearance in 24 (63.2%), axillary sampling in five (15.1%) cases, and sentinel lymph node biopsy in one (2.6%) case. Neoadjuvant chemotherapy was given to 10 (26.3%) patients, and adjuvant chemotherapy to eight (21.1%) patients. Adjuvant hormonal treatment was administered to 22 (57.9%) patients, and 13 (34%) patients received adjuvant radiation to the chest wall. The five-year overall survival was 38.2% and the median survival was 36 months. The five-year disease-free survival (DFS) was found to be 33.7%.ConclusionBreast cancer in males presents at an advanced stage with poor survival. Multicenter studies are required to accurately identify incidence, prognostic factors, and outcomes in order to have a better understanding of its management.
