Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
FFPE sample blocks and clinical information pertaining to the patients who satisfied with selection criteria will be collected from two institutions. The primary end point of this study is disease-free survival (DFS) that is defined as the time from surgery to death or gastric cancer recurrence whichever occurred first; and overall survival (OS) that is defined as time from surgery to death by any causes. Clinical information such as age, sex, histology, Lauren classification, depth of invasion, number of retrieved and metastatic lymph nodes, sizes of tumor, location of tumor, gross type, lympho-vascular invasion, received chemotherapy or not will be centralized.
One or 2 of 3mm core of tumor will be punched from FFPE and it will be delivered through Eppendorf tube to laboratory (Novomics Co. Ltd., Seoul, Korea). RNA will be extracted from the tissue and the pattern of RNA expression will be evaluated and each sample will be categorized into three risk group (high, intermediate, low risk group) and two predictive group (CTX-benefit and no-benefit group) by GMP-grade nProfiler 1TM Stomach Cancer Assay Kit (Novomics Co. Ltd., Seoul, Korea). Both clinical information and classification will be delivered to independent statisticians who are responsible to conduct statistical analyses.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CTX-benefit group
CTX-benefit group: based on the result of nProfiler Stomach cancer assay kit which was decided by expression level of mRNA, this group will be beneficial from adjuvant chemotherapy
No interventions assigned to this group
no-benefit group
no-benefit group: based on the result of nProfiler Stomach cancer assay kit which was decided by expression level of mRNA, this group will not be beneficial from adjuvant chemotherapy
No interventions assigned to this group
high-risk group
high-risk group: based on the result of nProfiler Stomach cancer assay kit which was decided by expression level of mRNA, the prognosis of this group will be worse compared to others regardless of the response to adjuvant chemotherapy
No interventions assigned to this group
