Detailed Description
31 patients with stage I, II, and III resectable soft tissue sarcoma were enrolled in this study at the Bone and soft Tissue Ward 1 of Henan Cancer Hospital. The main objective of this study was to evaluate the safety and efficacy of paamprimab combined with radiotherapy for neoadjuvant treatment of soft tissue sarcoma. The primary endpoint of this study was pathological complete response rate (CPR).
