Comparison of immune markers in POLE, MSI, and MSS endometrial cancers in the TCGA data set.(A) The relative numbers of nonsynonymous mutations found in POLE-mutant, MSI, and MSS endometrial cancers. (B) Heat map showing relative expression of differentially expressed immune-related genes in POLE-mutant, MSI, and MSS endometrial cancers. Number of samples: 27 POLE, 64 MSI, 104 MSS. Box plots (shown in A) use the following default convention: the horizontal line represents the median value, the box covers the interquartile range (IQR), the whiskers cover values within 1.5 IQR beyond the box, and values beyond 1.5 IQR are represented as dots.
