The study reveals that ADT treatment induces immunosuppression in the tumor microenvironment of prostate cancer, suggesting the potential clinical significance of combining ADT with immunotherapy.
RationaleTo invest the role of androgen deprivation therapy (ADT) on the tumor immune microenvironment of prostate cancer. MethodsHere we have profiled the transcriptomes of 19,227 single cells from 4 prostate tumors, including two cases who received ADT. To validated the single-cell analysis we use another group of patients receiving neoadjuvant ADT. ResultsAfter receiving ADT treatment, the killing effect of prostate cancer immune cells on tumors is weakened, the interaction between immune cells and tumor cells is weakened, and the proportion of immunosuppressive cells Myeloid-derived suppressor cell (MDSC) and Regulatory T cells (Treg) cells increases. ConclusionsOur results highlight that ADT induces immunosuppressive in the prostate tumor microenvironment. These data have important implications for combining ADT with immunotherapy.
