Colorectal cancer is a major health problem worldwide. The aims of our study are to provide an overview of the epidemiological and clinical characteristics of colorectal cancer in the anticancer center of Blida Algeria.


Through a retrospective study during 3 years; we determined the epidemiological and clinical characteristics of colorectal cancer collected in our unit.


374 patients were included, 201 men and 173 women. The mean age was 54.1 years (rang from 15 to 86). A history of familial polyposis adenoma was found in 7.9% of cases and notion of cancer in the family of the patients was 8.3%. The most frequent clinical presentation was abdominal pain (39.3%); rectal bleeding (29.7%); constipation and/ or diarrhea (26.7%) with a median of consultation period 6.5 months. The location of the tumor was a sigmoid colon 41% followed by 25.4% right colon and rectum in 21% of cases. Lieberkunien adenocarcinoma was the most common reported histological type of cancer (99%). Stage at diagnosis was in order stage IV, III and II with respectively, 41.1%, 30.6% and 28.3%. 154 patients presented with metastatic extension with 60.4% liver metastasis, 17.8% lung metastasis and 8.9% peritoneal carcinomatosis.


The comparison between our results and those western series shows that colorectal cancer occurs most frequently in young people; a longer time needed diagnosis and a high incidence of advanced disease.
