研究目的:

PD-1/PD-L1抑制剂为核心的免疫检查点抑制剂联合TNT方案已在多项II期临床研究中展现出显著的肿瘤退缩效应,为直肠癌器官功能保留提供可能,但现有临床研究呈现出治疗策略的高度异质性,特别是在免疫检查点抑制剂介入时机、联合治疗方案配伍等核心环节缺乏高质量循证医学证据。此研究目的为筛选具有临床优势的治疗策略,为后续III期确证性试验提供循证依据。  

Objectives of Study:

Immune checkpoint inhibitors centered on PD-1/PD-L1 inhibitors combined with the TNT regimen have demonstrated significant tumor regression effects in multiple phase II clinical studies, offering potential for organ function preservation in rectal cancer. However, current clinical research reveals substantial heterogeneity in treatment strategies, particularly lacking high-quality evidence-based medical evidence regarding critical aspects such as optimal timing for immune checkpoint inhibitor intervention and rational combination therapy regimens. This study aims to identify clinically advantageous therapeutic strategies and provide an evidence-based foundation for subsequent phase III confirmatory trials.
