  • Background Over the past few decades, immunological checkpoint therapy has been an increasingly prominent strategy in the treatment of tumors, including prostate cancer (PC). There are few systematic studies of the phenotypic of tumor-infiltrating immune cells in PC tissues.

    Methods CIBERSORT is an analytical tool for estimating the abundance of member cell types in mixed cell population by gene expression data. Herein, we analyzed different levels of tumor-infiltrating immunity cells in normal tissue compared with PC using CIBERSORT.

    Results The results showed that proportion of M1 macrophages and resting mast cells presented significant differences in prostate tumor than these normal tissues. A higher proportion of resting mast cells was associated with a worse outcome and M1 macrophages was associated with a favorable outcome. Moreover, the radiotherapy and targeted molecular therapy can affect the immune infiltration of M1 macrophages and resting mast cells.

    Conclusions Resting mast cells and M1 macrophages has an important role in the prognosis of prostate cancer. Our data provides valuable information about the future treatment of PC.
