Immune landscape of sarcoma. A Immune landscape of sarcoma. Each point represents a patient, and the immune subtypes are color-coded. The horizontal axis represents the first principal component (PC1), and the vertical axis represents the second principal component (PC2). B Heatmap for the estimated enrichment scores of 28 immune cell signatures in two principal components. The lower part of each cell represents the R value of the correlation, the upper part represents the P value of the correlation, and significant cells have a significant mark (asterisk). Positive and negative correlations are located to the left and right of the 0 axis, respectively. For the P value, the median value of the division is 1.3 (i.e., − log10(0.05)). If the P value < 0.05, the corresponding color gradient is purple, and the green gradient represents a P value > 0.05. C Immune landscape of the subsets of each sarcoma immune subtype. D The estimated enrichment scores of 28 immune cell signatures in the above subsets. E Immune landscape of samples from three extreme locations and their prognostic status. F Kaplan–Meier curves showing the PFS of sarcoma immune subtypes in the SARC cohort from TCGA
