Popis: Purpose Studies investigating the appropriate post-surgery follow-up method for elderly patients with colorectal cancer are limited. Thus, the purpose of this study was to compare survival rates between two follow-up methods in patients aged 80 years or older who underwent surgery for colorectal cancer. Methods Between January 1, 2002 and December 31, 2010, 165 patients aged 80 years or older underwent curative resection for non-metastatic colorectal cancer at the Department of Surgery, Seoul National University Hospital. Sixty-six of these patients were excluded due to the lack of follow-up, while the remaining 99 were included in our study. These 99 patients were divided into the following two groups depending on their post-surgery follow-up method. Patients who underwent follow-up on a regular basis, which was defined as once every six months to one year, with carcinoembryonic antigen (CEA) and computed tomography (CT) comprised the Regular group, and those who received follow-up with CEA alone or underwent CT procedures once every two years or more comprised the Minimal group. Overall survival was analyzed with the log-rank test and Cox regression analysis. Results Of the 99 patients, 62 were in Regular group and 37 were in Minimal group. There was no difference in overall survival rate between the two post-surgery follow-up methods (regular group vs. minimal group: 51.6% vs. 50.9% [5-year overall survival rate], P=0.819). Additionally, no significant differences was detected between the groups following multivariate analysis (harzard ratio=0.907; 95% confidence interval=0.460–1.788, P=0.777). Conclusion A significant survival gain was not observed between Regular and Minimal group. To draw a more definite conclusion, a multi-center randomized research study should be conducted.
