Objective: To compare the differences in clinical and pathological features and survival time between patients with left-sided colon cancer and rectal cancer. Methods: A total of 323 patients with colorectal cancer(CRC) underwent surgical resection at Changhai Hospital of the Second Military Medical University between January 2011 and January 2012 were enrolled in this study. The clinical data of patients were collected and the follow-up was started from the day of surgery or pathological confirmation with the death of patients as endpoints. The follow-up lasted until August 1,2017. Results: There were significant differences in initial symptoms, pathologic type, tumor stage, anemia before surgery, p53 positive rate, and BRAF mutation(χ~2=59.088,4.188,24.305,11.956,4.221,4.001,all P0.05) between patients with left-sided colon cancer and rectal cancer. For all the patients, the median survival time was not observed. The five-year survival rates of patients with left-sided colon cancer and rectal cancer were 79.2% and 74.3%, respectively. The Kaplan-Meier survival curves of patients at StageⅠ-Ⅱshowed that there was no statistical difference between patients with left-sided colon cancer and rectal cancer(P=0.840)and the survival of Stage Ⅲ patients between the two groups also showed no statistical difference(P=0.106). Cox regression analysis showed that both the pathologic types [HR=1.759, P=0.047] and tumor stage [HR=2.104, P0.001] were independent predictive factors for OS of CRC patients. Conclusion: There were no differences in survival time between patients with left-sided colon cancer and rectal cancer. The pathologic types and tumor stage were factors influencing the OS of CRC patients.
