[Epidemiological and pathological profile of colorectal cancer: about 36 cases]

Colorectal cancer is classified among the most common cancers in the world (after breast cancer and prostate cancer) and it is the second digestive tract cancer in Morocco after stomach cancer. However, its incidence in our country is lower than that of western countries (2.5 to 3.3 / 100 000 ha) but it coincides with that of Maghreb countries where this cancer affects young subjects in 27% of cases. Colorectal cancer (CRC) is one of the best examples of multistep carcinogenesis. Knowing the anatomopathological characteristics of CRC will certainly affect our therapeutic approaches. We conducted a retrospective epidemiological and anatomopathological study in the Department of Visceral Surgery at the Military Hospital Moulay Ismail, Meknes over a period of 5 years from January 2012 to December 2016. The study involved 36 patients: 14 women and 22 men. The aim of this study was to analyze the epidemiological profile and the anatomopathological features of colorectal cancers. The analysis of our results shows a specific epidemiological profile which is characteristic of a type of colorectal cancer affecting younger subjects, mainly male patients. Sporadic carcers are largely predominant, occurring mainly in the rectosigmoid region. A low degree of differentiation of adenocarcinomas with mucinous features is correlated with advanced TNM and Aster Coller staging and with lymph node status with poor prognosis. This multidisciplinary approach will be a novelty at national level, thus making our structure of clinical practice and research one of the centres for multidisciplinary management of colorectal cancer in Morocco.
