Colorectal cancer (CRC) is the fourth most common cancer in men and the third most common in women. In this study, we compared the characteristics such as age, sex, tumor grad, tumor location and overall survival rate in patients with colon and rectal cancer. We analyzed two groups of twenty-five patients with colorectal cancer (colon and rectal) that were referred to Department of Radiation and Oncology of Imam Reza hospital in between 2012 to 2015. We checked age, sex, tumor location, tumor grade, and survival. The data were analyzed using Microsoft Office Excel 2007 and Graph Pad Prism 5.The mean age for colon and rectal cancer was 57.60 ± 12.5 years (range, 27-75 years) and 54.48 ± 12.55 years (range, 30-75 years), respectively. Morecolon cancer patients are located in the age range of 60 to 69 years and about patients with rectal cancer are located under 50 years old. The results of the test for sex, age younger than 50 years, Age older than 50 years, mucin production and lymph node, margin and vascular involvement variables showed that for patients with colon cancer were equal, less, more, more and less, respectively in compared with rectal cancer. The 2-year survival rate for colon cancer (71%) is less than rectal cancer (76%).We found survival rate that in rectal cancer is better than colon cancer. It probably kind of pathology (mucinous adenocarcinoma type in colon cancer is more) and age of patients (more patients with rectal cancer are lower age) are two reasons for it.
