PURPOSE OF REVIEW: To summarize the role of chemotherapy and offer some guidance regarding the selection of chemotherapy in mPC. RECENT FINDINGS: Patients with mHSPC have varied prognoses with testosterone suppression alone (androgen deprivation therapy, ADT) and differential responses to docetaxel with ADT. Patients with de novo and metachronous high-volume disease have a robust survival benefit with the addition of docetaxel to hormonal therapies. Patients with synchronous low-volume disease have a more modest survival benefit from docetaxel and there is no evidence of survival benefit with docetaxel in patients with metachronous low-volume disease. Integration of biomarkers may refine treatment selection regardless of volume of disease. Docetaxel and cabazitaxel also impart an OS benefit in patients with metastatic castration-resistant prostate cancer (mCRPC). The choice of chemotherapy in mCRPC depends on treatment received in mHSPC setting. Docetaxel remains the first line chemotherapy in castration-resistant patients who have not received it in mHSPC followed by cabazitaxel, otherwise cabazitaxel can be deployed without docetaxel retreatment. SUMMARY: Chemotherapy is a key class of therapy for selected patients with mHSPC and mCRPC.
