SCHISTOSOMIASIS AND MALIGNANCY

It is generally accepted that schistosomiasis, if not causative, is at least associated with malignancy. In this review, the epidemiology of schistosomiasis and bladder carcinoma, as well as the role of chronic bladder infection, are discussed together with known carcinogenic fac tors, possible abnormal vitamin metabolism and/or deficiencies and fac tors that influence conjugated carcinogens. Experimental evidence is b riefly examined and recent work from the Far East on schistosomiasis a nd colon carcinoma reviewed.
