Marker for predicting gastric cancer prognosis and method for predicting gastric cancer prognosis using the same

A method for predicting gastric cancer prognosis, comprising:

• a) measuring an expression level of mRNA or protein of a marker for predicting gastric cancer prognosis in a sample collected from a gastric cancer patient to obtain a quantified expression value;
• b) applying the expression value obtained in step a) to a prognosis prediction model to obtain a gastric cancer prognostic score, wherein the prognosis prediction model is expressed as:
• [S=β1x1+ . . . +βnxn]
• wherein, xn is the quantified expression value of the n-th gene,
• βn is the Cox Regression estimate of n-th gene, and
• S represents the gastric cancer prognostic score;
• and
• c) comparing the gastric cancer prognostic score obtained in step b) with a reference value to determine prognosis of the patient,
• wherein the marker for predicting gastric cancer prognosis is a combination of C20orf103 (chromosome 20 open reading frame 103), MATN3 (matrilin 3), CLIP4 (CAP-GLY domain containing linker protein family, member 4), NOX4 (NADPH oxidase 4), ADRA2C (adrenergic, alpha-2C-, receptor), CSK (c-src tyrosine kinase), FZD9 (frizzled family receptor 9), GALR1 (galanin receptor 1), GRM6 (glutamate receptor, metabotropic 6), INSR (insulin receptor), LPHN1 (latrophilin 1), LYN (v-yes-1 Yamaguchi sarcoma viral related oncogene homolog) and MRGPRX3 (MAS-related GPR, member X3) genes.
