Chemotherapy-Forward Management of Advanced Prostate Cancer: Taxane Timing, Sequencing and the Real-World Place of...

Taxane chemotherapy remains a durable backbone in advanced prostate cancer, but its clinical value is increasingly determined by timing, sequencing, and deliverability. We synthesize pivotal randomized trials and contemporary guidance to provide a chemotherapy-forward framework spanning metastatic castration-sensitive prostate cancer (mCSPC) and metastatic castration-resistant prostate cancer (mCRPC). In mCSPC, early docetaxel added to androgen deprivation therapy-often as part of triplet intensification with an androgen receptor pathway inhibitor (ARPI)-offers the greatest absolute benefit in fit patients with high disease burden or aggressive clinical tempo. In mCRPC, docetaxel remains foundational, while cabazitaxel is preferred over ARPI switching after prior docetaxel and one ARPI, supporting mechanism-based sequencing. Practical implementation requires proactive toxicity prevention (especially neutropenia), dose and schedule individualization, and preservation of functional status to maintain eligibility for subsequent life-prolonging therapies. Immunotherapy has a limited but important niche: sipuleucel-T may benefit selected patients with low symptom burden, whereas immune checkpoint inhibitors are best reserved for biomarker-defined subsets such as microsatellite instability-high or mismatch repair-deficient tumors; tumor mutational burden should be interpreted cautiously in prostate cancer. Ongoing trials and emerging antigen-directed platforms will clarify whether chemotherapy can act as an immune-enabling partner in defined settings.
