title: A 50-year experience of male breast cancer: is outcome changing?
abstract: During the period 1933-1983, 124 men (median age 62.5 years, range 33-86 years) were treated for breast carcinoma. Median length of follow-up was 6.7 years and was complete for 93% of patients. Presenting complaints were most frequently a mass (95%) or pain (31%) while physical examination revealed the tumour to be central in 95% of patients with nipple or skin retraction in 36% and associated gynaecomastia in 12%. Twenty-seven per cent of the patients had a positive family history of breast cancer, 6% noted previous breast trauma and 7% had prior chest wall irradiation. Mean tumour size was 2.5 cm, and the pathological stage was 0 in 3%, I in 17%, II in 22%, III in 35%, IV in 11%, and unknown in 12%. Ninety-four per cent were ductal carcinoma. Histological grading of tumours was 2% grade 1, 10% grade 2, 33% grade 3 and 48% grade 4. Ninety-two per cent of patients underwent mastectomy (41% radical, 39% modified radical and 12% simple), while adjuvant irradiation was used in 44% and chemotherapy in 9%. Median disease-free patient survival was 5 years (36% of patients developed tumour recurrence). Median overall patient survival was 6.3 years (57% at 5 years and 31% at 10 years). Tumour size (P < 0.05), pathological stage (P < 0.04), and tumour grade (P = 0.007) were adverse factors for recurrence, while pathological stage (P < 0.02), tumour size (P < 0.03), pain (P < 0.05) and age (P < 0.02) were associated with a decreased survival.(ABSTRACT TRUNCATED AT 250 WORDS)
