Carcinoma of urinary bladder in a region of low schistosomiasis

Abstract

Aim: To study the geographical pathology of carcinoma of the urinary bladder as regards both its association with endemic schistosomiasis and the variable proportions of its histological types. Methods: A 30-year retrospective analysis was carried out with regard to Igbo patients who inhabit a region of low incidence of schistosomiasis with special reference to the occurrence of urinary carcinoma. Results: Carcinomas manifested in bladder biopsies from 24 patients and in cystectomy specimens from 12 patients. One case alone was associated with schistosomiasis. Conclusion: This lone case is a finding which is in consonance with the theory that the intensity of parasitic infestation is a significant factor in carcinogenesis.
