Abstract

PURPOSE
Male breast cancer is a rare type of neoplasm, account for 1 % of all breast tumors. A retrospective review of the clinical and histological characteristics, types of treatment, pathological staging, and adjuvant treatment was completed. The objective of this study was to make an early diagnosis of male breast cancer and reduce the mortality. METHODS: Over a 5-year period, from Oct. 1994 to July 2000, 10 male breast cancer patients were operated on in the breast cancer clinic of the Samsung Medical Center. Their duration of follow up ranged from 6 to 76 months with a mean of 26 months. The clinical and histological characteristics, associations of the risk factors, type of treatment, and results were studied. RESULTS: Their ages ranged from 40 to 67 years with a mean of 51 years, with 5, 3 and 2 cases in their 5th, 6th, and 7th decades, respectively. A palpable breast lump was the most common presenting symptom. A pathological assessment disclosed 8 infiltrating ductal carcinoma, 1 ductal carcinoma in situ, and 1 invasive adenoid cystic carcinoma. The tumor sizes ranged from 0.5 to 3.7 cm (median, 1.9 cm in diameter). Of the 10 patients, there were 3 T1b, 3 T1c, and 4 T2 in the tumor staging. 4 Patients had axillary node involvement (lymph node positivity, 40%), and of these 4, the metastasis involved 2 lymph nodes and more than 3 lymph nodes in 1 and 3 case, respectively. No distant metastasis was observed in any of the patients. Pathological stages of the patients 0, I, IIIA, and IIIB in 1, 5, 1 and 2 cases, respectively. All the patients underwent surgery, 7 with a modified radical mastectomy and 3 with a radical mastectomy, due to gross invasion of the pectoralis major muscle. CONCLUSION: A subareolar palpable breast mass was the most common presenting symptom of the male breast cancer patients. The optimal treatment for male breast cancer patients is a modified radical mastectomy, combined with radiotherapy, chemotherapy, and hormonal therapy, due to the higher hormone receptors positivity.
