Abstract

Background and Objective: In previous studies there were conversely in survival rate of the sides of colorectal cancer (CRC). Differences in the survival rate for CRC have been observed among the left-sided and right-sided tumors, with further regional variation. There was inconsistency in survival rate varies by regions. The objective of this study was to compare the survival rate between left and right-sided tumors after diagnosis of CRC patients at Maharat Nakhon Ratchasima hospital, Nakhon Ratchasima province.


Methods: Data (2,096 cases) were collected from the Maharat Nakhon Ratchasima hospital-based cancer registry (2014-2018) in Nakhon Ratchasima province. The survival rate was estimated using the Kaplan-Meier method. Between group compassions were made using the Log rank test. We reported the median survival time and 95% confidence interval.


Result: Of 2,096 CRC patients, 1,209 died during the study period, corresponding to a case-fatality rate of 31.4 per 100 person-years (95%CI: 29.6-33.1). The median survival time was 1.95 years. (95%CI: 1.77-2.12). The overall survival rates at 1, 3, and 5 years were 66.6% (95%CI: 64.5-68.5), 39.3% (95%CI; 37.0-41.5), and 30.3% (95%CI; 27.7-32.8), respectively.  The survival rate between the left and right-sided tumors was not significantly different (Log rank test = 0.59, p=0.444).


Conclusion: The survival rate between right- and left-sided CRC lesions was not significantly different. The 5-year survival rate is poor; consequently, primary prevention is crucial and screening for early detection is necessary to improve survival rate. Further research should focus on the factors affecting survival of CRC.
