Aspects épidémiologiques, nutritionnels et anatomopathologiques des cancers colorectaux dans la région du grand Casablanca

INTRODUCTION: colorectal cancer is a major public health problem. This study aims to analyze the epidemiological, nutritional, clinical and anatomopathological features of patients with colorectal cancer at the University Hospital in Casablanca. METHODS: our case-control study focused on patients assigned to treatment for colorectal cancer in 2015 compared with a control group that didn’t have cancer. RESULTS: the average age of our patients was 56.65 years, with a standard deviation of 14.64. The most common histological type of cancer in study patients was Lieberkhünien adenocarcinoma with a proportion of 82%. The analysis of the body mass index showed that 50% of study patients were obese vs 20% of patients in the control group and that 19% of study patients had diabetes vs 8% patients in the control group (p< 0.019). Moreover, the analysis of dietary habits in study patients compared to those of patients in the control group showed that the average frequency of weekly consumption of red meat was higher in study patients than in the control group (4.24 vs 3.26; p = 0.009) and , conversely, for the consumption of fish (0.97 vs 1.76; p = 0.0001). On the other hand, the average consumption of vegetables and fruits was lower in study patients than in the control group (5.00 vs 9.50; p = 0.0001). Concerning the toxic habits of our patients, 32% of study patients were smokers vs. 13% of patients in the control group. CONCLUSION: our results show that awareness about our dietary habits and changes in our living habits could reduce the incidence of colorectal cancer and therefore mortality and morbidity.
