This study is a pilot study and the result will be used as a reference for the upcoming prospective randomized controlled trial for same issue including estimating sample size. Two high-volume hospitals (Yonsei University Severance Hospital and Samsung Hospital) will participant this pilot study.\n\nFFPE 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.\n\nOne 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.
