Clinical Trial Summary

This study is a multi-center, prospective, randomized controlled study. The aim of this study is to compare survival rates and to observe quality of life and nutritional status according to follow-up period in patients who underwent radical gastrectomy for stage 2 or 3 gastric cancer.


Clinical Trial Description

The hypothesis of this study is that the survival rates would be different between the 3 months and 6 months follow-up groups. The investigators expected survival differences of 6% and the anticipated 3-year overall survival is 83% in the 6 months follow-up group based on the previous 3 phase clinical trial. On the basis of this hypothesis, the sample size was calculated as 886 patients. Patients who were diagnosed as stage 2 or 3 gastric cancer after gastrectomy will be assigned to 3 months or 6 months follow-up group. The planned examinations including blood test, X-ray , CT, endoscopy, and nutritional markers will be performed according to the protocol and each patients will be followed up for 3 years after enrollment. The primary endpoint is 3 year overall survival and secondary endpoints are other survivals such as 3-year disease-free survival and gastric cancer specific survival, quality of life, and nutritional parameters. ;
