Study on the Optimal Combination Pattern of the Combined Treatment of Radiotherapy and Immunotherapy for the Abscopal Effect in Non-Small Cell Lung Cancer (NSCLC) With Multiple Metastases

Summary

This study aims to conduct a prospective, multicenter, umbrella clinical study to compare the abscopal effects of different radiotherapy fractionation patterns combined with Benmelstobart, and to explore an efficient and low-toxic treatment strategy for non-small cell lung cancer (NSCLC) with multiple metastases. The main objective is to explore and compare the control rates of abscopal lesions in NSCLC patients with multiple metastases when different radiotherapy fractionation patterns are combined with Benmelstobart.
