Description
Shuou Sudo and co-authors present a 2026 prospective registry study of proton therapy for inoperable trunk soft tissue sarcoma. These rare tumors sit deep in the body, often near vital organs, which makes surgery impossible for some patients. Proton beams can concentrate dose on the tumor while sparing nearby tissue.
All patients in the registry had trunk tumors that could not be removed. The most common subtype was a fat-tissue cancer variant. Local control at three years looked strong in the cohort. No severe treatment-related side effects were recorded. Quality of life measures held steady overall during follow-up. The authors offer proton therapy as a definitive option where surgery is off the table.
