Filter by:The purpose of this process is to clarify the characteristics of gut microbiota changes in patients with locally advanced rectal cancer undergoing preoperative neoadjuvant treatment, and to identify key bacterial species closely related to sensitivity to radiotherapy. This aims to elucidate the mechanism linking gut microbiome dysbiosis with radiotherapy sensitivity, thereby providing new combined treatment strategies to enhance the efficacy of radiotherapy.
This is a multicenter, prospective, randomized controlled study to evaluate the effectiveness and safety of neoadjuvant chemoradiotherapy combined with PD-1 inhibitor and PCSK9 inhibitor in the treatment of patients with pMMR/MSS locally advanced middle and low rectal cancer.
TORCH-iTNT is a prospective, multicentre, randomized phase II trial. 198 LARC (T3-4/N+M0, distance from anal verge ≤12cm) patients will be treated with total neoadjuvant therapy (TNT) and assigned to Group A and Group B (1:1). Group A receives 6 cycles of Toripalimab combined with CAPOX (ToriCAPOX). Group B receives SCRT (25Gy/5Fx) followed by 6 cycles of ToriCAPOX. TME surgery is scheduled after TNT while a watch and wait (W&W) option can be applied to patients achieving clinical complete response (cCR). The primary endpoint is complete response (CR, pathological complete response [pCR] plus cCR) rate. The secondary endpoints include the grade 3-4 acute adverse effects (AE) rate, anal preservation rate, 3-year DFS rate, etc.
phase II clinical trial to evaluate node-sparing short-course radiation combined with total neoadjuvant CAPOX and Sintilimab for MSS locally advanced rectal cancers.
This is an open, prospective, multi-center, single-arm phase II clinical study assessing the efficacy and safety of neoadjuvant chemoradiotherapy combined with PD-1 inhibitor and thymalfasin in patients with pMMR/MSS locally advanced middle and low rectal cancer.
Previously, preliminary results, from a subgroup analysis of STARS-RC03 (NCT04906044) conducted by our research team, showed that the 6-cycles consolidation chemotherapy combining with anti-PD-1 therapy had a better tumor regression advantage with a restricted safety profile contrasted with 3-cycle counterparts. Herein, we designed this study to further evaluate the short-term efficacy (such as pCR rate, R0 resection rate, etc.) and long-term survival (including DFS, OS, etc.) of 6-cycles consolidation therapy.
This study is a single-arm, open-label, multicenter clinical study to evaluate the efficacy and safety of preoperative short-course radiotherapy combined with AK104 and chemotherapy + TME surgery in patients with advanced rectal cancer.
This is an open-label, prospective phase II clinical trial to evaluate the therapeutic and prognostic implications of tumor immune microenvironment in the neoadjuvant immunotherapy combined with chemoradiotherapy for patients with rectal cancer. A total of 100 patients will be enrolled in this trial. The primary end point is the rate of pathological complete response (pCR). The long-term prognosis and adverse effects will also be evaluated and analyzed.
To investigate dynamic change of gut microbiomes and metabolites, and their effects on immune modulation. To evaluate the efficacy and safety of TNT with GEN-001 (Lactococcus lactis) and identify predictive biomarkers for pathologic response in patients with locally advanced rectal cancer (LARC).
The treatment of locally advanced and recurrent rectal cancers is highly individualized to each patient and their pattern of disease, and this decision is often made at the Multidisciplinary Team (MDT) meeting . The PelvEx collaborative was designed with the intent to provide greater international consensus on appropriate treatment decisions for this cohort. However, we propose that international variation exists in how certain patients will be evaluated, assessed and ultimately treated despite having the same disease. We plan to measure this variation in order to provide a greater understanding of the differences that exist.
