Abstract
Introduction & Objective: Colorectal carcinoma is one of the most prevalent cancers. Early diagnosis and diagnosis in primary stages are important in patient’s prognosis. In this study we evaluated factors such as age, sex, stage and tumor location in colorectal patients in five year peroid. Materials & Methods: From the cancer database of a single referral institution, Shariati Hospital 109 patients who had resection of colorectal cancer from 1999 to 2002 were identified. Cases with recurrent colon cancer or previous history of neoadjuvant chemotherapy were excluded. Survival curves were constructed using the kaplan-meier method. The factors that were used included: age, sex, TNM stage, T-status, nodal status, distant metastasis, grade, lymphatic and vascular invasion, tumor location, preoperative CEA level and liver function tests. Multivariate analysis of factors was conducted using cox-regression analysis. Results: The mean survival time for all patients was 42.8±2.8) months. The overall 1, 3, 5 year survival rates were 72%, 54%, 47% respectively. The single variable analysis, patients age (P
