To characterise male breast carcinoma among black South Africans and to compare the findings with those for white males in the same area.
Data were prospectively collected for all patients presenting to the Johannesburg Hospital breast clinics over a 14-year period. The breast clinics see all patients from Johannesburg and the surrounding area, both from government hospitals and private clinics. Sixty-nine black, 20 white and 2 Asian males were found to have breast carcinoma during this period.
Although black males presented with a longer history of symptoms than white males (median 12 v. 2 months), and at a later stage of their disease (> 80% v. 40% stage III or IV), there did not appear to be any fundamental differences in the disease between the two groups. Median age at presentation (59 v. 62 years) was not significantly different, the spectrum of histopathological types was similar, and 5-year survival stage for stage was the same: 88% for stage I, 50% for stage II, 27% for stage III, and 5% for stage IV. The incidence of carcinoma among black males appeared to be the same as for white males, but there did seem to be a decreased incidence of breast carcinoma in the black female population.
There are no true differences between breast carcinoma occurring in black and white South African males. Previous African reports have suggested an increased incidence of breast carcinoma in black males because the figures have only been compared with those for black females.
对南非黑人男性乳腺癌的特征进行描述，并将研究结果与同一地区的白人男性进行比较。
前瞻性收集了约翰内斯堡医院乳腺门诊14年间所有患者的数据。该乳腺门诊接待来自约翰内斯堡及周边地区政府医院和私立诊所的所有患者。在此期间，发现69名黑人男性、20名白人男性和2名亚洲男性患有乳腺癌。
尽管黑人男性出现症状的时间比白人男性长（中位时间分别为12个月和2个月），且疾病分期较晚（Ⅲ期或Ⅳ期分别为>80%和40%），但两组疾病似乎没有本质区别。就诊时的中位年龄（分别为59岁和62岁）无显著差异，组织病理学类型谱相似，各分期的5年生存率相同：Ⅰ期为88%，Ⅱ期为50%，Ⅲ期为27%，Ⅳ期为5%。黑人男性的乳腺癌发病率似乎与白人男性相同，但黑人女性人群的乳腺癌发病率似乎有所下降。
南非黑人和白人男性患乳腺癌不存在真正差异。以前非洲的报告表明黑人男性乳腺癌发病率增加，是因为只将这些数据与黑人女性的数据进行了比较。
