Abstract
In Senegal colorectal cancer cases account for 2.5% of all cancers. This prevalence is underestimated as due to the inaccessibility to care. The aim of our study was to describe anatomopathological and epidemiological characteristics in patients with colorectal cancer in Senegal. This is a prospective, descriptive and analytical study from 2012 to 2015 on patients having undergone surgery for colorectal cancer. 41 cases were selected on a more important number of filed cases. Data based on factors such as age, sex, tumor location, and diagnosis of stage (TNM) were studied using the Excel software. The average age of our patients was around 50 and the majority was above 60. The sex ratio was 0.76 for women. Our study population was dominated by the Wolof ethnic group, which accounted for over half of the targeted population (51%). Other ethnic groups were poorly represented. Adenocarcinoma histology was dominant, with preferential localization at the left colon. The stage of diagnosis according to the TNM classification was pT3. Our study shows that the majority of patients come to consultation at a somewhat advanced stage. Alongside this analytical study, a genetic study of DNA will be performed at the Laboratory of Biochemistry and Molecular Biology at the University Cheikh Anta Diop of Dakar.
