Abstract

Objective: We aimed to determine the demographic characteristics of colorectal cases and changes in cancer localization according to years in our region.

Materials and Methods: In the present study, 752 patients diagnosed with colorectal cancer between January 1992 and December 2010 were included.

Results: Of all the patients, 427 (56.8%) were males and 325 (43.2%) were females, with a male/female ratio of 1.3/1. The mean age was 56.2±14.9 years. The most commonly encountered complaint at the first application was rectal bleeding (38.4%). The most commonly encountered tumor localizations were in the rectum (55%) and sigmoid colon (18%). In general, tumors were observed to be localized in the right colon at 16.1% and in the left colon at 83.9%. When tumor localizations were compared in the first 10 years of the study with the second 10 years in the present study, it was observed that tumor numbers in the right colon were increased. Cases in our study were diagnosed as Stage IV according to the tumor, node, metastasis (TNM) classification, and liver metastasis was encountered most commonly.

Conclusion: Although colorectal cancer cases have been most commonly encountered in the rectum, it has been recently determined that right colon tumor percentages were increased. It was defined that they were generally diagnosed at later stages. Therefore, colorectal cancer incidence may be decreased by the widespread use of endoscopic techniques in the determination of precancerous lesions.
