GC patients with Gp2 tumors had a significantly longer median OS (158 months) compared to the other molecular groups (median OS was 28.5 months in Gp1, 13.5 months in Gp3, 19 months in Gp4, and 13 months in Gp5) (p < 0.05) (Fig. 6c and Supplementary Table 16). Here, GP2 is linked to gastric cancer.
