Figure 6. Immune cells infiltration analysis based on CIBERSORT in PCa bone metastases. (A) The percentage of 22 immune infiltration cells in the training cohort was compared between PCa in situ (n =58) and PCa bone metastases (n=58). (B) The OS analysis of naive B cells, CD4 memory resting T cells, and M1, M2 macrophages in the training cohort. In the training cohort (C) and validation cohort (D), the percentages of 22 immune infiltration cells divided into low- or high-risk groups designated by the OS predicted model were compared.
