Sequential TAS-OX Alternating With TAS-IRI Plus Bevacizumab for Late-Line Metastatic Colorectal Cancer
This study is to evaluate the disease control rate and time to progression of the sequential combination of oxaliplatin with an alternative anti-metabolite Trifluridine/tipiracil hydrochloride mixture, TAS-102,(TAS-OX) as well as irinotecan in combination with TAS-102 oxaliplatin(TAS-OX) + Bevacizumab in late-line metastatic colorectal cancer (mCRC)
Multi-points and Full-thickness Biopsy in the Diagnosis of cCR After Neoadjuvant Therapy for Rectal Cancer
Background There is currently no reliable means to restage rectal cancers after neoadjuvant chemoradiation. There are still no reliable methods to identify patients with pCR before radical surgery. As a result, clinical complete response (cCR), defined as no clinical detectable tumor by physical examination, endoscopic evaluation, and imaging, is designed …
Nodes-sparing Short-course Radiation Combined With CAPOX and Tislelizumab for MSS Middle and Low Rectal Cancer
This is an open-label, prospective, multicenter phase II clinical trial to evaluate modified short-course radiation (Radiation targeting the tumor bed without irradiating surrounding tumor-draining lymph nodes) combined with CAPOX and PD-1 Inhibitor (Tislelizumab) for patients with MSS middle and low rectal cancer. A total of 32 patients will be enrolled …
Organ Preservation in Rectal Cancer: Contact X-ray Brachytherapy vs Extending the Waiting Interval and Local Excision
The goal of this prospective phase II feasibility study is to evaluate two additional local treatment options in rectal cancer patients with a good clinical response after neoadjuvant (chemo)radiation: contact x-ray brachytherapy versus extension of the waiting interval with or without local excision, and to investigate which rate of organ …
Phase II RCT of LCRT vs SCRT + CAPOX/PD-1i/COX-2i in MSS Locally Advanced Rectal Cancer
This randomized phase II trial evaluates the efficacy of long-course chemoradiotherapy (50Gy/25Fx + capecitabine) versus short-course radiotherapy (25Gy/5Fx) combined with CAPOX（Capecitabine and Oxaliplatin）, PD-1 inhibitor (serplulimab), and COX-2 inhibitor (celecoxib) in MSS（MicroSatellite Stable） locally advanced rectal cancer, with primary endpoint of complete response rate (pCR+cCR)（Complete Remission） and secondary endpoints including …
Drug Sensitivity Detection of Micro Tumor (PTC) to Guide Postoperative Adjuvant Treatment Strategy of Colorectal Cancer
The research objectives is to compare vitro 3D drug sensitivity test results of micro tumor (PTC) with the clinical outcomes of patients, evaluate the consistency between the test results of the technology platform and the clinical prognosis, and explore the decision-making value and guiding significance of this technology in assisting …
Node-Sparing Short-Course Radiotherapy Sequential Chemotherapy and PD-1 Inhibitor for Mid/Low pMMR/MSS Rectal Cancer (MODIFI-RC-II)
Most rectal cancers are microsatellite stable (MSS) or mismatch repair-proficient (pMMR) and respond poorly to PD-1 inhibitors. Radiotherapy can enhance tumor antigen release and improve responsiveness to PD-1 blockade in MSS/pMMR rectal cancer. Tumor-draining lymph nodes (TDLNs) are critical sites for anti-tumor immune activation, but radiation-induced damage and fibrosis may …
Modified Long-Course Radiotherapy Followed by Chemotherapy and PD-1 Inhibitor for MSS/pMMR High-risk Mid/Low LARC (MODIFI-RC-I)
The goal of this clinical trial is to evaluate whether a total neoadjuvant therapy (TNT) regimen combining long-course chemoradiotherapy, sequential chemotherapy, and PD-1 inhibitor can improve response rates, enhance tolerability, and improve prognosis in patients with locally advanced, microsatellite-stable (MSS) rectal cancer. The main questions it aims to answer are: …
An Investigational Scan (64Cu-Labeled M5A Antibody) in Combination With SOC Chemotherapy and Radiotherapy in Locally Advanced Rectal Cancer
This early phase I trial investigates how well 64Cu-labeled M5A antibody scan works in assessing tumor activity before and after patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced) who are undergoing chemotherapy and radiotherapy. Using 64Cu-labeled M5A positron emission tomography imaging may play …
A Bowel Management Program (Retrograde Rectal Enema) for the Treatment of Low Anterior Resection Syndrome in Rectal Cancer Patients
This clinical trial studies if a bowel management program with a retrograde rectal enema (RRE) for the treatment of low anterior resection syndrome (LARS) in rectal cancer patients is better than medical management alone. Rectal cancer treatment can include a procedure where part of the rectum with cancer is removed …
