Background
Male breast cancer (MBC) management is extrapolated from female BC. Mastectomy remains the most frequently used surgical procedure for male breast cancer (MBC). We performed a literature review to assess the use of breast-conservation (BCS) in MBC as well as outcomes following BCS.
Methods
A systematic literature was performed, and articles screened to identify studies that measured overall survival (OS), disease-free survival (DFS), or local recurrence (LR) in patients undergoing BCS. Weighted averages based on study size were performed for LR, DFS, and 5-year OS.
Results
Eight studies met the inclusion criteria with male breast surgery cases, and 859 (14.7%) underwent BCS. The mean follow-up time was 53 months, and mean age was 62.6 years, with stage II as the most common presentation. Two studies reported that 50–71.4% of patients underwent sentinel lymph node biopsy, and four studies reported axillary lymph node dissection in 14.3–100%. Five studies reported on adjuvant radiation therapy in 12.0–100% of total patients undergoing BCS. Four studies reported use of hormonal therapy in 73.8–100% of patients. Four studies reported use of chemotherapy in 25–66.7% of patients. Seven studies reported LR among 116 patients, with a weighted average of 9.9%. Three studies reported on DFS in 14 patients, with a weighted average 85.6%. Two studies report OS in 143 patients with a weighted average of 84.4%.
Conclusions
Breast conservation may be considered a safe alternative in the surgical treatment of MBC. Future research should focus on better standardization of local therapy for MBC and improved reporting of outcomes.
