Abstract
10753 Background: A single-institution retrospective review of the clinical presentation, treatment and outcome of male breast infiltrating ductal carcinoma (IDC). Methods: Case records of 25 male patients with a histological diagnosis of infiltrating ductal carcinoma (IDC) of breast who were treated in a single institution between 1997 to 2004 were retrospectively reviewed. Results: Patients presented at a mean age of 56 years (range, 34 to 80 years). The presenting complaint was a painless lump in the breast in all the cases. The right breast was involved in 13 cases (52%). There were no cases of bilateral breast cancer. The distribution of patients by stage at presentation are: stage IIA (24%), IIB (20%), IIIA (8%), IIIB (40%), and IV (8%). None of the patients presented with stage I disease. One patient had lung metastases at presentation. Rest of the 24 patients (96%) underwent surgery (modified radical mastectomy, 22 patients; simple mastectomy, 2 patients). Fifteen patients (60%) received adjuvant local radiotherapy. All patients received adjuvant chemotherapy: As per departmental protocol, those presenting before 2000 were treated using a regimen of Cyclophosphamide, Adriamycin and 5-Fluorouracil. After 2000, Ebirubicin was substituted for Adriamycin. Three patients were further administered Docetaxel, the indication being disease progression after first line adjuvant chemotherapy. Estrogen & Progesterone receptor positivity was 64% and 60% respectively. Hormonal therapy (Tamoxifen 14 patients, Anastrozole 2 patients) was administered in these patients. The length of follow-up from time of presentation ranged from 4 to 100 months (mean, 28 months; median, 13 months). At the time of analysis, of the 25 patients, 18 patients (72%) remain disease free, whereas 7 patients (28%) developed progressive disease. Median survival was not reached at the present time. Conclusions: Breast cancer, specifically IDC tends to present at a later stage in males, due to a lack of screening for the disease. In the present series, as a result of the advanced stage of initial presentation, all patients received adjuvant chemotherapy. There is a need to improve awareness among males, of the possibility of a painless breast lump being the first symptom of an underlying malignancy. No significant financial relationships to disclose.
