Filter by:The aim of this work is to assess the antitumor effect of Pentoxiphylline in patients with metastatic colorectal cancer receiving stomatal chemotherapy ± targeted therapy.
This Phase Ib trial studies the side effects and best dose of LB-100 and azenosertib for the treatment of patients with metastatic colorectal cancer. Azenosertib blocks a protein that is involved in the repair of damaged DNA, this protein is called WEE1. Inhibiting WEE1 drives cancer cells into a state of cell division without repair of the damaged DNA, resulting in cell death. LB-100 has been shown to make anticancer drugs work better at killing cancer. LB-100 blocks a protein called PP2A. Blocking this protein increases the stress signals for the tumor cells that express PP2A. Research has shown that azenosertib and LB-100 may enhance each others effect when treating metastatic colorectal cancer.
For locally advanced rectal cancer, the initial goal of neoadjuvant chemoradiotherapy is to reduce local recurrence, but the pathologic complete response (PCR) rate is low, and distant metastasis becomes the main treatment failure pattern. With the gradual optimization of neoadjuvant chemotherapy regimens, the tumor regression efficacy in patients has improved, leading to increased organ preservation and reduced distant metastasis. Therefore, neoadjuvant treatment for locally advanced rectal cancer has transitioned from an era focused on local control of recurrence to an era focused on improving tumor regression, organ preservation, and long-term survival. Thus, there is a trend towards intensifying the whole course of neoadjuvant treatment for rectal cancer to preserve organ function. The combination of chemotherapy, immunotherapy, and radiotherapy is currently the most powerful approach to maximize tumor regression and achieve organ preservation in low rectal cancer. Currently, several clinical studies on the use of PD-1 inhibitors in combination with preoperative chemoradiotherapy for locally advanced rectal cancer are ongoing internationally, with the majority focusing on PD-1 monotherapy or PD-1 combined with the CapOX regimen in combination with synchronous chemoradiotherapy as neoadjuvant treatment. However, there is no specific research reported on the use of PD-1 combined with FOLFOXIRI regimen in combination with synchronous chemoradiotherapy as a whole course neoadjuvant treatment for pMMR (proficient mismatch repair) locally advanced rectal cancer. Based on the above evidence from evidence-based medicine, we plan to conduct a phase II prospective clinical study to explore the efficacy and treatment safety of PD-1 monoclonal antibody and FOLFOXIRI chemotherapy combined with intensity-modulated radiotherapy as a whole course neoadjuvant treatment in pMMR locally advanced low rectal cancer. The results of this study may open up new treatment approaches for optimizing whole course neoadjuvant chemotherapy in locally advanced rectal cancer and provide a novel treatment strategy for organ preservation in pMMR rectal cancer.
To evaluate the efficacy and safety of TAS-102 combined with bevacizumab as first-line therapy in patients with advanced colorectal cancer who could not tolerate or did not receive combined chemotherapy
This study is a prospective, multicenter, and exploratory study aimed at evaluating the effectiveness of Huaier Granules in preventing postoperative recurrence and metastasis of colorectal cancer.
This study is a phase Ⅱ, randomized, controlled, open-label, multi-center study with safety run-in to evaluate the efficacy and safety of JMT101 combined with Irinotecan and SG001 in Patients with Metastatic Colorectal Cancer (mCRC).
This real-world study tries to collect data reflecting routine use of SIR-Spheres in patients diagnosed with unresectable liver metastases from Metastatic Liver Tumors From Primary Colorectal Cancer (mCRC) refractory to or intolerant to chemotherapy, in order to assess clinical response in a real-world setting and further validate the safe and appropriate use of SIR-Spheres in China.
Robotic right hemicolectomy with intra-corporeal anastomosis may have better short-term recovery outcomes and decreased incidence of incisional hernia when compared to the laparoscopic actual standard of care, for similar safety outcomes.
The goal of this clinical trial is to learn about clinical usefulness endoscopic gastrointestinal anastomoses to restore the gastrointestinal continuity in patients with permanent colostomy after Hartmann procedure. The main questions it aims to answer are: - is the endoscopic restore the gastrointestinal continuity procedure effective? - is this endoscopic procedure safe?
The goal of this pilot clinical trial is to learn about the combination of immune boosting drugs and irreversible electroporation (IRE) in patients with colon cancer that has spread to the liver (metastasis). The main questions it aims to answer are: 1. to document the rate of complications associated with combining IRE with immune boosting drugs. 2. After one liver metastasis is treated with IRE and immune boosting drugs, what is the change in the size of the non-IRE-treated liver metastases? 3. What is the immune response (measured in a blood sample) when IRE is combined with one or two types of immune boosting drugs?
