The Efficacy and Safety of Short-course Radiation Combined With Adebrelimab and CAPEOX Neo-adjuvant Therapy for Organ-retention in Patients With MSS/pMMR Ultra Low Rectal Adenocarcinoma

Rectal Adenocarcinoma Clinical Trial

Official title:
The Efficacy and Safety of Short-course Radiation Combined With Adebrelimab and CAPEOX Neo-adjuvant Therapy for Organ-retention in Patients With MSS/pMMR Ultra Low Rectal Adenocarcinoma: A Prospective, Single-arm Study

Clinical Trial Summary

To evaluate the efficacy, safety and organ retention rate of short-course radiation combined with Adebrelimab and CAPEOX neoadjuvant therapy in patients with MSS/pMMR ultra low rectal adenocarcinoma.

Clinical Trial Description

At present, neoadjuvant chemoradiotherapy (nCRT) combined with total mesorectal excision (TME) is the main standard treatment, and the choice of treatment modalities is limited. The emergence of immunotherapy has provided a new direction for the exploration of neoadjuvant therapy for rectal adenocarcinoma. At the same time, a number of studies have also shown that appropriate radiotherapy intensity can promote immune response. Therefore, the investigators intend to conduct the clinical trail to explore the effect of short-course radiotherapy combined with PD-L1 combined and chemotherapy as TNT (total neoadjuvant therapy) on organ retention rate in patients with With MSS/pMMR Ultra Low Rectal Adenocarcinoma. ;
