Alterations in the tumor suppressor genes (TSGs) RB1, PTEN, and TP53 are associated with treatment resistance, worse survival, and aggressive variants of prostate cancer (AVPC). We previously developed and validated a signature reflecting low TSG expression (TSGlow) that was associated with poor outcomes in patients with metastatic hormone-sensitive prostate cancer (mHSPC) treated with androgen deprivation therapy (ADT) ± docetaxel.
