Short Course Radiation Therapy and Combination Chemotherapy for the Treatment of Stage II-III Rectal Cancer
This phase I trial investigates how well short-course radiation therapy followed by combination chemotherapy works in treating patients with stage II-III rectal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as leucovorin, fluorouracil, oxaliplatin, and capecitabine, work in different ways to …
Iparomlimab/Tuvonralimab Integrating With Total Neoadjuvant Therapy for pMMR/MSS Locally Advanced Rectal Cancer (IT-TNT)
In colorectal cancer (CRC), ICIs show strong therapeutic associations with microsatellite instability-high (MSI-H) status, while patients with proficient mismatch repair/microsatellite stable (pMMR/MSS) tumors exhibit poor responses. Dual immunotherapy may represent a promising strategy for MSS populations. The Dutch NICHE trial reported a 27% pathological response rate (4/15) in MSS CRC …
Short-course Radiotherapy Followed by AK112 and CAPOX as Neoadjuvant Therapy for Locally Advanced Rectal Cancer
This study aims to evaluate the efficacy and safety of short-course radiotherapy followed by AK112 in combination with CAPOX as neoadjuvant therapy in patients with locally advanced rectal cancer
Papaverine in Combination With Radiation Therapy for the Treatment of Locally Advanced Rectal Cancer, DINOMITE Trial
This phase I trial studies the side effects and best dose of papaverine (PPV) when given together with radiation therapy (RT) and tests how well it works in treating patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced). PPV is an enzyme inhibitor, and …
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 …
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 …
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 …
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: …
