Summary

The goal of this clinical study is to evaluate the efficacy and safety of sintilimab combined with rituximab followed by R-CHOP regimen in treatment-naïve patients with primary mediastinal diffuse large B-cell lymphoma. The main questions it aims to answer are: 1. Objective response rate of sintilimab combined with rituximab 2. Objective response rate after R-CHOP regimen

Detailed description

Participants will first receive sintilimab plus rituximab for 2 cycles, followed by interim PET-CT assessments. If patients achieve CR or CMR, they will continue to receive 2 courses of sintilimab plus rituximab, followed by 4 cycles of R-CHOP. Patients will receive 6 courses of R-CHOP if they do not achieve CR or CMR after 2 cycles of sintilimab plus rituximab. Patients will undergo PET-CT assessment and will receive 6 cycles of maintenance treatment with nintedanib if CR/CMR/PR is achieved and will be withdrawn from the study if SD/PD occurs. Total treatment cycles will not exceed 14 cycles
