Active clinical trials for "Liver Neoplasms"

For patients with unresectable colorectal cancer liver metastases, preclinical studies have shown that after the resistance of cetuximab, the treatment sensitivity can be restored by stopping cetuximab for a period of time. This is called the cetuximab re-challenge. And the circulating tumor DNA (ctDNA) test is reported a biomarker for the efficacy of cetuximab rechallenge. However, there is still no randomized controlled trial for verification. This study aims at patients after the first-line treatment of cetuximab has progressed. After the second-line non-cetuximab treatment has progressed, the effects of re-application of combined with cetuximab and chemotherapy alone are compared to verify the re-challenge effect.

In the structure of malignant liver lesions, two main groups are distinguished - primary liver cancer and metastatic liver damage. The five-year survival rate of patients with malignant liver tumors does not exceed 6%. The main and radical method of treatment today is liver resection. However, surgical treatment is possible only in 10-25% of patients. At the same time, recurrence of malignant tumors is observed in 60-80% of cases within five years after surgery, and the number of candidates for repeated liver resection does not exceed 10%. The high toxicity of systemic chemotherapy limits its use in this group of patients. In this connection, minimally invasive and at the same time effective methods of local treatment of malignant liver tumors have been introduced into clinical practice. These methods include: hepatic artery chemoinfusion, chemoembolization and oil chemoembolization. Currently, a large world experience has already been accumulated in the application of the above methods of treatment. However, any, even minimally invasive, surgical manipulation can be associated with the development of complications of varying severity. If complications arise, there is a risk of interruption of palliative care, which entails a significant reduction in life expectancy. According to domestic and foreign literature, the occurrence of complications after intra-arterial chemoembolization occurs in 0.4-10% of patients, and after intra-arterial chemoinfusion - in 5-30% of patients. In the overwhelming majority of scientific works, the description of the complications that have arisen is reduced to listing the latter. Currently, in the Russian and foreign scientific literature there is no systematization of complications, there is no single clinical classification, algorithms for the prevention and treatment of complications arising after local intravascular methods of treatment of patients with malignant liver tumors. The study and systematization of complications arising after intra-arterial chemoembolization and chemoinfusion of the hepatic artery in patients with malignant liver tumors will make it possible to create prevention and treatment algorithms. Thus, it will help prevent interruption of palliative care and increase the life expectancy of this cohort of patients.

Multicentric prospective and observational study to assess the 5-year overall survival in a cohort of patients with unresectable liver-only colorectal metastases, well controlled by chemotherapy prior to liver transplantation.

The main objective of this trial is to determine feasibility and tolerance of the human body to RFA associated with local immunomodulation carried out using a thermoreversible hydrogel combined with 2 immunomodulators, GMCSF and Mifamurtide. The main endpoint of the study is the feasibility, the frequency and the nature of per and post-operative adverse events of the in situ injection of an immunomodulatory hydrogel after radiofrequency of unresectable colorectal liver metastases. The secondary objective is one-year progression free survival rate.

The Multi-OutcoMe EvaluatioN of radiation Therapy Using the Unity MR-Linac Study (MOMENTUM) is a multi-institutional, international registry facilitating evidenced based implementation of the Unity MR-Linac technology and further technical development of the MR-Linac system with the ultimate purpose to improve patients' survival, local, and regional tumor control and quality of life.

This study is to collect and validate regulatory-grade real-world data (RWD) in oncology using the novel, Master Observational Trial construct. This data can be then used in real-world evidence (RWE) generation. It will also create reusable infrastructure to allow creation or affiliation with many additional RWD/RWE efforts both prospective and retrospective in nature.

Colon cancer and primary liver cancer are common malignant tumors with low survival rate worldwide, and unresectable primary liver cancer and colon cancer liver metastases have worse prognosis. End-stage liver disease is equated with advanced liver disease, liver failure and decompensated cirrhosis because they are generally irreversible. Liver transplantation is a treatment option for the above-mentioned patients and is expected to improve the prognosis of the patients, but the biggest problem faced by such patients is the shortage of donor livers. Recently, a new surgical modality, resection and partial liver segment 2-3 transplantation with delayed total hepatectomy (RAPID), can greatly alleviate these problems.Based on clinical surgical experience, our center proposes and designs a clinical study of adjuvant liver transplantation combined with two-stage hepatectomy in the treatment of patients with unresectable primary liver cancer, colorectal cancer liver metastases, or end-stage liver disease. By improvement of RAPID operation, the safety and efficacy of this treatment method in patients with those disease were evaluated.

This is an open, one-arm study to evaluate the safety and efficacy of mRNA personalized tumor vaccine (tumor vaccine) encoding neonatal antigen in combination with Sintilimab injection for adjuvant prevention of postoperative recurrence of hepatocellular carcinoma.

The aim of this study is to explore the therapeutic effect of Quintuple method in the treatment of patients with multiple and refractory liver metastases from colorectal cancer. A randomized single-arm clinical trial was conducted.The intervention group was treated with single SOX chemotherapy, SOX chemotherapy combined with cetuximab targeted therapy, SOX chemotherapy combined with low-dose cetuximab targeted therapy combined with three-drug regimen（Quintuple method）, and the RECIST 1.1 solid tumor evaluation criteria were used to assess the disease.

This study is a prospective, multicenter, randomized controlled clinical trial to evaluate the safety and efficacy of polyvinyl alcohol sodium acrylate embolization microspheres and HepaSphere Microspheres loaded with irinotecan for the treatment of colorectal cancer with hepatic metastases through arterial chemoembolization.
