In a retrospective study 184 biopsy reports of primary malignant bladder tumours in males which had been received from the Department of Pathology, University of Natal, during 1971-1982 were analysed. The age and race of the patients, the histological type of the tumours and the presence or absence of concomitant schistosomal infection were noted. There were 103 squamous and 62 transitional cell carcinomas, and 19 adenocarcinomas or undifferentiated types of malignant tumour. Of the patients 153 were Blacks and 31 Indians, 61,4% of the Blacks had squamous cell carcinoma, as against 29% of the Indians (P less than 0,01). Bladder carcinoma among Blacks occurred at a younger age (5th decade) than that among Indians (6th decade). The prevalence of schistosomiasis in the whole group was 40,8%. The prevalence was highest in the Blacks (44,4%); in the Indians it was 22,6%. Schistosomal infection was most commonly associated with squamous cell carcinoma (61%) (P less than 0,0001).
在一项回顾性研究中，对1971年至1982年期间从纳塔尔大学病理学系收到的184份男性原发性恶性膀胱肿瘤活检报告进行了分析。记录了患者的年龄和种族、肿瘤的组织学类型以及是否存在血吸虫感染。其中有103例鳞状细胞癌、62例移行细胞癌以及19例腺癌或未分化型恶性肿瘤。患者中153人为黑人，31人为印度人，61.4%的黑人患有鳞状细胞癌，而印度人这一比例为29%（P<0.01）。黑人膀胱癌的发病年龄（第五个十年）比印度人（第六个十年）要小。整个研究组中血吸虫病的患病率为40.8%。黑人中的患病率最高（44.4%）；印度人中为22.6%。血吸虫感染最常与鳞状细胞癌相关（61%）（P<0.0001）。
