The Types segment classifies the market by therapeutic modality, including Hormone therapy, Chemotherapy, Targeted therapy, Immunotherapy, and Radiopharmaceuticals. Hormone therapy remains the backbone of treatment, employing luteinizing‑hormone‑releasing hormone (LHRH) agonists/antagonists and anti‑androgens; its broad indication across all application categories yields the highest cumulative sales despite modest unit prices. Chemotherapy, principally docetaxel and cabazitaxel, is confined to metastatic and CRPC settings, contributing a mid‑range share due to higher drug costs but limited patient eligibility. Targeted therapy—including PARP inhibitors and PI3K pathway agents—captures a growing niche, driven by biomarker‑guided prescribing that elevates average revenue per patient. Immunotherapy (e.g., checkpoint inhibitors) currently occupies a marginal share, reflecting ongoing clinical validation. Radiopharmaceuticals such as lutetium‑177‑PSMA deliver high‑value, disease‑specific treatment for advanced stages, rapidly expanding its market proportion. Collectively, these types delineate the market taxonomy that underpins revenue allocation across the Prostate Cancer Treatment Drugs market.
