Capecitabine

This is a randomized, controlled clinical trial based on prior exploratory findings, designed to evaluate the efficacy and safety of neoadjuvant chemoradiotherapy combined with tafolecimab(an anti-PCSK9 inhibitor) and sintilimab (an anti-PD-1 inhibitor) versus neoadjuvant chemoradiotherapy combined with sintilimab alone in patients with pMMR/MSS locally advanced rectal cancer. The primary endpoint is the complete response (CR) rate, including the pathological complete response (pCR) rate in patients who undergo surgery after neoadjuvant therapy, and the clinical complete response (cCR) rate in patients managed with a watch-and-wait strategy. Secondary endpoints include major pathological response (MPR) rate, objective response rate (ORR), downstaging rate, R0 resection rate, tumor regression grade, sphincter preservation rate, disease-free survival (DFS), overall survival (OS), and safety.

Safety and Efficacy of Organ Preservation Treatment for Stage I Rectal Cancer: Optimization of Consolidation Chemotherapy Before Local Excision After Neoadjuvant Chemoradiotherapy (OPTION); A Multi-center, Prospective, Randomized Trial The goal of this clinical trial is to find out if adding consolidation chemotherapy with capecitabine after total neoadjuvant chemoradiotherapy (TNT) works to improve oncologic outcomes in patients with stage I rectal cancer. It will also comparethe safety of adding consolidation chemotherapy before local excision. The main questions it aims to answer are: * Does adding consolidation chemotherapy increase the rate of pathologic complete response? * What medical problems or side effects do participants have during and after treatment? Researchers will compare TNT followed by local excision to TNT followed by consolidation chemotherapy with capecitabine and then local excision to see if adding consolidation chemotherapy improves tumor response and treatment outcomes. Participants will: * Receive TNT for stage I rectal cancer * Be randomly assigned to one of two treatment groups * Undergo local excision after preoperative treatment * Visit the clinic for checkups and tests to evaluate tumor response, side effects, recurrence, survival, quality of life, bowel function, urinary function, sexual function, circulating tumor DNA, and treatment-related costs

This study is a single-arm, multicenter, open-labeled clinical study of UTD1 combined with Capecitabine in metastatic HER2-negative breast cancaner patients with brain metastases. This study aims to evaluate the efficacy and safety of UDT1 combined with capecitabine in metastatic HER2-negative breast cancer patients with brain metastases.

This study is a single-center, Phase II Study to assess the efficacy and safety of the regimen of Nanoliposomal Irinotecan and XELOX (NALIRI-XELOX) in combination with Cadonilimab in subjects with advanced pancreatic ductal adenocarcinoma who have not previously received systemic treatment.

This study hypothesizes that electroacupuncture combined with self-administered acupressure plus doctor-prescribed treatment is effective in preventing Hand-Foot Syndrome (HFS) caused by capecitabine. It aims to explore the effectiveness of this combined approach in preventing HFS in patients with malignant tumors undergoing oral capecitabine treatment. Further exploration of prevention and treatment methods may enhance the quality of life for patients during the treatment process.

This multicenter, randomized, controlled, phase III study is conducted to evaluate the efficacy and safety of first line mCapOX plus Cetuximab versus mFOLFOX6 plus Cetuximab for RAS/BRAF wild-type, MSS, Unresectable Left-Sided mCRC.

The goal of this clinical trial is to compare XELOX +Bev +Tislelizumab with standard chemotherapy，in MSS/pMMR-type RAS-mutated metastatic colorectal adenocarcinoma. The main questions it aims to answer are efficacy and safety of the regimen of XELOX +Bev +Tislelizumab. The investigators want to transform ras-mutated colorectal cancer into a "hot tumor" through the combination of anti-vascular therapy and chemotherapy, and then achieve better therapeutic effect through the combination with immunotherapy. Participants will receive the regimen of XELOX +Bev +Tislelizumab.

This study is a multi-center, single-arm, open-label phase II clinical trial, aiming to observe and evaluate the perioperative treatment of tislelizumab combined with chemotherapy (CAPOX) in stage II or III colorectal cancer with MSI-H/dMMR Patient efficacy and safety.

This is a single-arm, multicenter, prospective, open-label phase II clinical trial of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy treating oligometastatic nasopharyngeal carcinoma, the main purpose of which is to evaluate the efficacy of multi-target radiotherapy combined with PD-1 monoclonal antibody and capecitabine maintenance therapy regimen in treating oligometastatic nasopharyngeal carcinoma.
