研究目的:

探究短程放疗序贯化免对比长程放化疗序贯化疗用于pMMR/MSS高危局部晚期直肠癌全程新辅助治疗的3年无事件生存率(3yEFS%)差异,以及完全缓解(CR)率、3年器官保留率(3yOP%)、3年总生存率(3yOS%)、3年无病生存期(3yDFS%)、3年无远处转移发生率(3yDMFS%)、3年无局部复发生存率(3yLRFS%)、3度及以上毒性反应率、手术并发症率、生活质量和肛门功能评分等的差异。  

Objectives of Study:

To investigate the differences in 3-year event-free survival rate (3yEFS%) between short-course radiotherapy followed by sequential chemoimmunotherapy and long-course chemoradiotherapy followed by sequential chemotherapy for total neoadjuvant therapy in high-risk pMMR/MSS locally advanced rectal cancer, as well as differences in complete response (CR) rate, 3-year organ preservation rate (3yOP%), 3-year overall survival rate (3yOS%), 3-year disease-free survival rate (3yDFS%), 3-year distant metastasis-free survival rate (3yDMFS%), 3-year local recurrence-free survival rate (3yLRFS%), grade 3 or higher toxicity rate, surgical complication rate, quality of life, and anal function score.
