A Clinical Trial Comparing Long-Course Versus Short-Course Radiotherapy Followed by Immunotherapy Combined With Total Neoadjuvant Therapy (TNT) to Long-Course Radiotherapy Followed by TNT in High-Risk Locally Advanced Rectal Cancer

This study is a national multicenter, prospective randomized controlled Phase III clinical trial designed to investigate the potential therapeutic benefit of immunotherapy combined with total neoadjuvant therapy (TNT) and to compare the efficacy of different radiotherapy modalities followed by immunotherapy.

Evaluating the Impact of GLP-1 Receptor Agonists With Total Neoadjuvant Therapy in Rectal Cancer

The goal of this clinical trial is to see if adding a weight loss medication (GLP-1 receptor drug) to patients with an increased BMI receiving treatment for rectal cancer prior to surgery (total neoadjuvant chemoradiotherapy) improves cancer outcomes. The main questions it aims to answer is 1. Does the drug increase weight loss in rectal cancer patients with a high BMI 2. Does the drug improve response rates to chemotherapy and radiotherapy 3. Does the drug improve survival outcomes and if cancer returns Researchers will compare this drug in one group against a group of patients receiving preoperative total neoadjuvant chemoradiotherapy without the drug Patients will be required to 1\) take the GLP-1 receptor agonist drug during TNT or just having TNT alone as per standard hospital protocols Body weight will be measured at three predefined time points: 1. Baseline: Prior to initiation of semaglutide or TNT 2. Pre-TNT: Start of TNT (for the intervention arm, this is 4 weeks after semaglutide initiation) 3. Post-TNT: Within 7 days following completion of TNT and prior to definitive surgery Patients will complete their treatment and go on to have surgery as per standard methods for treating rectal cancer

SCRT Followed by CAPOX + Bev ± PD-1 Inhibitor for TNT in LARC

This study aims to evaluate the efficacy and safety of short-course radiotherapy combined with CAPOX plus bevacizumab with or without a PD-1 inhibitor in patients with locally advanced rectal cancer (LARC). The hypothesis is that the addition of immunotherapy (PD-1 inhibitor) can significantly improve the complete response (CR) rate and enhance local control while reducing the incidence of distant metastasis. This study will compare the effects of sequential chemoradiotherapy and targeted therapy with or without immunotherapy following short-course radiotherapy, aiming to explore the optimal regimen for total neoadjuvant therapy.

Personalized Long-course Radiotherapy Plus Chemotherapy With or Without Immunotherapy for LARC: PALACE Study

The study is a multicenter, randomized controlled, phase III clinical study, and the purpose of the study is to explore the complete response rate (CR, Defined as pathological complete response (pCR) + Clinical complete response (cCR) sustained for over one year) of patients with locally advanced rectal cancer(LARC) treated with personalized long-course radiotherapy plus chemotherapy with or without Serplulimab. A total of 184 patients were included in this study.
