[Cancer of schistosomiasis-infected bladders. Apropos of 6 cases].

It is a well known fact that patients with urinary schistosomiasis are at risk for carcinoma of the bladder. Although relatively few cases are seen in France. Among 130 patients with urinary schistosomiasis hospitalized in our department from April 1980 to December 1984, 6 cases of carcinoma of the bladder were diagnosed. Our series has a number of specific characteristics: patients are Black Africans, and the anatomoclinical characteristics of these tumors differ from those found in vesical tumors in Europeans free of schistosomiasis, with, apparently, a greater sensitivity to chemotherapy.
