Clinicopathological differences between right- and left-sided colonic tumors and impact upon survival

Abstract

This study is to analyze the clinicopathological differences between right- and left-sided colonic tumors and to evaluate the impact upon the patient’s survival. In a period of 5 years (2004–2009), 453 patients were diagnosed with colorectal cancer. From a total of 453 patients diagnosed with colon cancer, 56.5% of them were men, while 43.5% of them were women. Right-sided colonic tumors were diagnosed in 54.53% of the patients compared to the 45.47% of patients with left-sided colonic tumors. The size of colonic tumors is statistically significant greater in right-sided colonic tumors compared to left ones (P < 0.001). Left-sided colon cancer patients identified to have a statistically significant better overall 5-year survival rate compared to right-sided ones (P < 0.001). Based upon our results, there is a different biological profile between right- and left-sided colonic tumors.
