In Kaplan-Meier analysis, OS of these GC patients (n=364) without CDKN2A SCND was significantly longer than those (n=187) with CDKN2A SCND (Cox univariate regression analysis: hazard ratio=0.767, 95% confidence interval=0.592-0.994; Figure 2A). The gene discussed is CDKN2A; the disease is gastric cancer.
