Management
chemotherapy (androgen-independent metastatic disease)
- docetaxel 36 mg/m2 IV weekly for 4 weeks, with or without calcitriol 45 mg PO 1 day prior to docetaxel[1]
- docetaxel + prednisone every 3 weeks[2]
- inhibition of CYP17 with abiraterone acetate +/-dexamethasone[3][4] is standard-of-care[8]
- addition of the PARP inhibitor olaparib (Lynparza) to abiraterone (Zytiga) as initial treatment extends median progression-free survival[8]
- addition of the PARP inhibitor talazoparib (Talzenna) to enzalutamide (Xtandi) significantly improved radiographic progression-free survival[9]
- cabozantinib shows promise in clinical trial
- no benefit of chemotherapy in addition to androgen deprivation prior to androgen-independence[5][6]
- lutetium-177 PSMA-617 extends overall survival 15.3 vs 11.3 months vs standard therapy[7]
