Radiotherapy Followed by Tiselizumab Combined With RCHOP in Previously Untreated Bulky Follicular Lymphoma

Phase 2

Recruiting

• Conditions: Follicular Lymphoma
• Interventions: Radiation: radiation therapy; Drug: Tiselizumab; Drug: Rituximab; Drug: Cyclophosphamide; Drug: Doxorubicin; Drug: Vincristine; Drug: Prednisone

• Registration Number: NCT06704555
• Lead Sponsor: Tianjin Medical University Cancer Institute and Hospital

Brief Summary

This was a single center, single arm, phase II study. Patients with previously untreated follicular lymphoma were enrolled from the department of lymphoma, Tianjin Medical University Cancer Institute and Hospital. The bulky disease was received radiation (dose:18～24Gy) before RCHOP. Patients began chemoimmunotherapy 1～2 weeks later than radiation. Treatment ...
