Colorectal Metastasis to Liver Extraction With Auxiliary Transplant and Delayed Resection

Liver transplantation (LT) has become an accepted treatment for selected patients with unresectable liver metastases due to colorectal cancer (CRLM). The goal of this study is to look at and compare the clinical results of all the different approved methods (living vs. Deceased, whole organ vs. Split, one staged vs. Two staged) used to perform a standard liver transplant procedure for recipients with CRLM. Investigators will look at things like different procedure results, recovery in the hospital, and survival rates one year after the transplant. Investigators will also take blood samples from participants to be used in future research. All the transplant methods the investigators are comparing are standard practices approved by the United Network of Organ Sharing (UNOS).

Injection of IP-001 Into Thermally Ablated Hepatic Tumors in Patients With Colorectal Liver Metastases

The goal of this clinical trial is to learn if a new injectable drug (IP-001), administered after standard liver tumor ablation, can help prevent cancer from returning in people (males/females, ≥18 years old) with colorectal cancer that has spread only to the liver. The study will determine if injecting IP-001 into a liver tumor(s) after ablation will reduce the risk of cancer coming back in the liver and from spreading elsewhere in the body, will stimulate the immune system, will have any side effects, and will help improve a patient's response to other cancer therapies. Researchers will compare a standard of care liver ablation alone (microwave ablation \[MWA\], a technique that destroys tumors using heat), with MWA plus a high-dose IP-001 or MWA with a low-dose IP-001. During the treatment procedures, the doctor first performs the standard microwave ablation to destroy the tumor. Then, in the experimental-drug arms, IP-001 is injected in and around the treated tumor area to activate the immune system locally so that the body is more likely to find and eliminate any remaining cancer cells.

FMT+ QL1706+Bevacizumab+ XELOX as First-line Treatment for Advanced MSS-type Colon Cancer With Liver Metastasis

The investigators plan to initiate a prospective, multicenter, phase II study, recruiting 30 patients with advanced colon cancer patients with liver metastasis who have not received prior treatment. This study plans to reconstruct intestinal microecology through fecal microbiota transplantation (FMT), and combine with QL1706+Bevacizumab+XELOX to enhance the anti-tumor immune effect at the same time, thereby improving the prognosis of colon cancer patients with liver metastasis.

SALT for Unresectable Colorectal Liver Metastases

Colon cancer is a common malignancy with a low survival rate worldwide, and unresectable colon cancer liver metastases (ICRLM) have a worse prognosis. The liver is the most common metastatic organ of colorectal cancer, and palliative chemotherapy is the only option for most ICRLM patients. Regrettably, the median survival time of all patients receiving chemotherapy is only 2 years, and the 5-year survival rate is only 10%. Liver transplantation is an ideal choice for patients with ICRLM, which can significantly improve the postoperative survival rate. But the most serious problem facing such patients is the shortage of donor livers. In 2015, Norwegian scholars proposed a new surgical method, that is, resection and partial liver segment (2-3 segment) transplantation combined with delayed total hepatectomy can greatly alleviate the shortage of liver donors in the above-mentioned patients. Based on the experience of clinical operation, our center proposes and designs a clinical study of sequential adult left lateral lobe liver transplantation (SALT) for the treatment of iCRLM. On the basis of RAPID, the safety and efficacy of sequential adult left lateral lobe liver transplantation were evaluated for the above patients.
