Rectal cancer is a frequent presentation, with an estimated 35% of cases found situated in the rectum. The aim of this study is to survey on patients with rectal cancer and report of 2 and 3 overall survival rates of them. Between of 2011 and 2016 years, 102 patients with rectal cancer referred to Department of Radiation Oncology in Imam Reza hospital, Kermanshah city, Iran. We analyzed sex, age, type of pathology, grade tumor, overall survival, lymph node, margin and vascular invasionin patients. Curve of the OS was plotted by Kaplan-Meier plot in Graph Pad prism 5 Software in 2 and 3-year period. The mean age of patients at diagnosis was 52.83±14.58 years (range: 17-79 years) that fifty-four patients (52.9%) were male. Kind of pathology in 90 patients (90%) was invasive adenocarcinoma and 10 patients (10%) was mucinous adenocarcinoma. Tumor grade of seventy-seven, twenty-two and one patients was well, moderately and poorly differentiated, respectively. Thirty-seven, twenty-two and twenty-four percent of patients had lymph node, margin and vascular invasion, respectively. The two and three years overall survival rate in our study were 78% and 70%, respectively. Our results are similar to other studies. We should have some studies on therapeutic methods, the role of biomarkers, genetic and environmental factors about rectal cancer in future.
