The colorectal cancers in hospitals in Ouagadougou : epidemiological and diagnostic aspects, endoscopic approach (About 43 cases)

Abstract

Purpose of the study is to describe the epidemiological and diagnostic aspects of colorectal cancer in hospitals
in ouagadougou. This was a retrospective and cross-sectional study over a period of 9 years and 6
months. it concerned patients with colorectal lesions suspected of malignancy at colonoscopy. The variables
studied were sociodemographic, clinical, endoscopic and histological. The study was carried out in 5
health structures and 3 pathology laboratories. 43 suspicious lesions were histologically confirmed. The
annual frequency was 4.53 new cases, the sex ratio of 0.87 and the mean age of 49.56 years. housewives
(30.09%) and lower-level employees (20.37%) were the most affected occupations. Twenty-six colonic cancers
(60.47%) and 17 rectal cancers (39.53%) were found. The budding forms (47.06%) were the most visualized
for rectal cancer and ulcero-budding, ulcero-budding and stenosing (26.92% each) for the colon.
adenocarcinoma was the most recovered (86.42%). histology and endoscopy were concordant in 65.49% of cases. Colorectal cancers seem rare in our country. however, only the establishment of a cancer registry
could make it possible to determine the actual impact.
