Immunological subtypes of gastric cancer and associations with survival. (a, b) The association between immunological subtypes and overall survival (OS) and progression‐free survival (PFS) was analysed by the Kaplan–Meier method, and the log‐rank test was used to determine the statistical significance of the differences. (c) A decision tree for the immunological subtypes of gastric cancer was applied to 29 gastric cancer patients. The sum of IGS1 to IGS6 of < 18.21 was taken as the cut‐off value to identify the Cold subtype. Similarly, IGS7 < 3.78 was determined as the cut‐off value for Intermediate and IGS9 < 2.11 was used to discriminate Hot1 from Hot2 tumors. (d) A decision tree for the immunological subtypes of gastric cancer was applied to 323 gastric cancer patients in the TCGA cohort. (e) The frequency of molecular subtypes of TCGA in each immunological subtype. (f) The frequency of immunological subtypes in each molecular subtype of TCGA. (g) Kaplan–Meier analysis and log‐rank test for OS of 311 gastric cancer patients for the four immunological subtypes.
