研究目的:

通过对新辅助放化疗联合艾帕洛利托沃瑞利单抗治疗pMMR/MSS局部进展期低位直肠癌的临床研究,可能提升患者的cCR率,达到器官保留功能,提高生活质量的目的。  

Objectives of Study:

Clinical research on neoadjuvant chemoradiotherapy combined with Epalrestat and Tuvonralimab in the treatment of locally advanced low rectal cancer with pMMR/MSS may improve the clinical complete response (cCR) rate of patients, achieve organ preservation, and enhance their quality of life.
