Preoperative Short-course Radiation Followed by Envafolimab Plus CAPEOX for MSS Locally Advanced Rectal Adenocarcinoma
Short-course radiotherapy combined with immunotherapy may bring revolutionary changes to the preoperative neoadjuvant treatment mode for locally advanced rectal cancer.In view of the shortcomings of the current preoperative neoadjuvant treatment model for locally advanced rectal cancer, we will explore the feasibility of a new model of short-course radiotherapy combined with …
Liver Magnetic Resonance Imaging Before Treatment for Rectal Cancer. A Randomised Controlled Trial.
This multicentre randomized controlled trial aims to investigate whether an abbreviated MRI is comparable to a combined single venous phase CT with an additional 3 min equilibrium phase of the liver, in the pretreatment radiological workup in patients with rectal cancer.
Neoadjuvant CIETAI With Concurrent Chemoradiotherapy in Local Advanced Rectal Cancer
To increase the efficacy of neoadjuvant PD-1/PD-1 checkpoint inhibitor in local advanced rectal cancer (LARC), we propose preoperative arterial infusion of Tirellizumab and oxaliplatin followed by tumor artery embolization with concurrent chemoradiotherapy as neoadjuvant regimen for LARC.
Organ Preservation in Rectal Cancer by Dose Escalated MR Guided Adaptive Radiotherapy
This study is testing whether radiation delivered with MRI guidance using a so-called MR-linac in distal rectal cancer can result in a high rate of organ preservation. Patients will receive radiotherapy together with standard chemotherapy.
A Study on the Accurate Evaluation of Pseudoprogression of Rectal Cancer Immunotherapy Based on Multitemporal and Multiparameter MRI
This project aims to use multi-temporal, multi-parameter MRI features, blood biomarkers, and clinical indicators to accurately assess pseudoprogression following immunotherapy in rectal cancer.
Low Rectal Cancer Treated With Total Neoadjuvant Therapy Plus Concurrent Tislelizumab Immunotherapy
This is an open-label, multi-center, single-arm clinical study. All patients received 4-6 cycles total neoadjuvant therapy plus concurrent tislelizumab immunotherapy, then underwent clinical response assessment. Patients who achieved CR (cCR+ pCR confirmed by local resection of ncCR) continue tislelizumab combined with CAPOX for another 4 cycles and tislelizumab for 9 …
Neoadjuvant Radiotherapy for Rectal Adenocarcinoma With Capecitabine Versus TAS-102 (Neo-REACT): A Multi-center, Randomized, Phase III Trial
Neoadjuvant fluoropyrimidine-based chemoradiotherapy followed by total mesorectal excision (TME) is the standard of care for locally advanced rectal cancer (LARC); however, pathologic complete response (pCR) rates are low. Trifluridine/tipiracil (TAS-102) is a new oral anti-tumor oral formulation of nucleoside analogue, trifluridine (FTD), and a thymidine phosphorylase inhibitor, tipiracil (TPI). Previous …
Response-adapted Total Neoadjuvant Therapy Guided by Induction Chemotherapy in Early- and Intermediate-risk Low Rectal Cancer for Implementation of a Watch-and-wait Strategy
This study investigates the feasibility of an organ-preserving "watch-and-wait" strategy in patients with mid-to-low rectal cancer who achieve a good response after total neoadjuvant therapy (TNT). By retrospectively and prospectively analyzing patients who complete TNT following effective induction chemotherapy, the study aims to assess organ preservation rates and evaluate whether …
Leucine Plus Radiochemotherapy for Neoadjuvant Treatment of Locally Advanced Rectal Cancer
Colorectal cancer (CRC), a prevalent gastrointestinal malignancy, is experiencing a rising incidence in China. Rectal cancer constitutes nearly half of all new CRC cases, with over half of these patients diagnosed at a locally advanced stage. While neoadjuvant chemoradiotherapy is the standard of care for these patients, it yields a …
Watchful Waiting for Complete Responders to Therapy in Rectal Cancer
The purpose of this project is to determine if in a selected group of patients, at higher risk of wound dehiscence and other complications, treatment by local excision and management by a "watchful waiting" or an initial "non-operative management" approach, with an offer of radical resection only to those patients …
