Type‑based Sarcoma Drugs segmentation classifies agents by their pharmacologic mechanism, revealing how each class underpins market revenue. Tyrosine‑kinase inhibitors (TKIs) such as imatinib, pazopanib and regorafenib constitute the largest share, roughly 45 % of the market, because they address both GIST and a subset of STS with durable response profiles. Cytotoxic chemotherapy, represented by doxorubicin, ifosfamide and gemcitabine, contributes about 30 % and remains the backbone of first‑line therapy despite modest incremental efficacy. Immunotherapy, primarily checkpoint inhibitors (pembrolizumab, nivolumab) and emerging adoptive‑cell products, accounts for roughly 15 % of sales, reflecting early‑stage adoption and ongoing trial activity. Targeted agents outside the TKI family—such as CDK4/6 inhibitors, MDM2 antagonists and epigenetic modulators—capture the remaining 10 % and are projected to accelerate as pipeline candidates receive regulatory clearance. This type taxonomy clarifies the revenue architecture and highlights where R&D investment is likely to reshape the market composition.
