Difficult Causality Relationship between Colorectal Cancer and Schistosomiasis
The purpose of the study was to determine the nature of the association between colorectal cancer and schistosomiasis infection. This was a retrospective and descriptive study of colorectal cancers and to identify cases associated with schistosomiasis. A total of 814 cases of rectal colorectal cancer were collected and 3 cases were associated with schistosomiasis. These are 2 cases of Liberkunian adenocarcinoma and one case of malt lymphoma. The patients were all farmers and from rural areas. A co-infection with HIV was found in his 3 patients.
