The Type dimension of the Gastrointestinal Stromal Tumors (GSTs) Treatment market is divided into four principal categories: tyrosine kinase inhibitors (TKIs), monoclonic antibodies, immunotherapy agents, and surgical interventions. TKIs—such as imatinib, sunitinib, and regorafenib—represent the dominant share, accounting for roughly 55 % of total revenue, driven by their first‑line positioning and extensive clinical data. Monoclonic antibodies, primarily targeting KIT and PDGFRA pathways, contribute about 10 % and are gaining traction in combination regimens. Immunotherapy agents, including checkpoint inhibitors under investigation, hold a modest 5 % share but reflect high growth potential as emerging biomarkers refine patient selection. Surgical interventions, encompassing laparoscopic and open resections, occupy the remaining 30 % of the market, reflecting the continued need for curative resection in localized disease. Each type adds a distinct cost structure and volume profile, collectively shaping the overall market size and informing investment decisions across the GSTs treatment landscape.
