Filter by:The goal of this interventional clinical trial is to evaluate the dose of radiation of Technetium-99m macroaggregated-albumin (99mTc-MAA) after an intra-arterial injection to the whole body and non-liver critical organs in patients who are undergoing evaluation for SIR-Spheres treatment for hepatocellular carcinoma.
This study aims to analyse retrospectively the feasibility, the safety, and the efficiency, of biliary or digestive protection with room air interposition for thermal ablation of central liver tumors with high iatrogenic risk. Thermal ablation is a mini-invasive and curative treatement of liver tumors. However, it requires to be carefull about surrunding organs, such as digestive structures or central biliary tree, which can be injured if not insulated. The technique of gas interposition to protect adjacent gut is already known and validated with carbonic gas. Nevertheless, resorption of this gas is very fast, making its use tricky to keep a correct insulation during the whole thermal ablation process. Room air interposition is easy to use and can offer a slow resorption speed. Furthermore no datas are available concerning the use of room air whatever the organ protected, and the protection of central biliary tree whatever the gas used.
The standard treatment of advanced hepatocellular carcinoma (HCC) is sorafenib. Though the agent showed clear survival benefit in two randomized phase III trials, the benefit was modest and response rate was just a few percent. Therefore, other loco-regional modalities, like trans-arterial chemo-embolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and radiotherapy (RT) were continuously tried, especially in locally advanced HCC including portal vein tumor thrombosis (PVTT). With the advancement of conformal RT techniques, RT was actively applied in HCC, especially in PVTT combined HCC. Many researchers reported that there is a relationship between RT dose and tumor response rate. RT dose, however, is frequently limited because the complications (like radiation induced liver disease (RILD), radiation induced gastro-duodenal toxicity, etc.) are also closely related with higher exposed RT dose. Proton beam has characteristic depth-dose distribution contrast to photon, the "Bragg peak". The advantage of this dose distribution could be more highlighted in HCC management, because of the weakness and maintenance importance of liver function itself in HCC patients. In fact, the superior results of proton beam therapy in HCC were constantly reported in several groups as prospectively as well as retrospectively. In those background, the investigators planned the present study to evaluate the efficacy and safety of proton beam therapy in HCC patients combined with PVTT.
To study if the administration of corticoid hinder or enhance the mobilization of Mesenchymal Stem Cells (MSCs) in the peripheral blood during liver transplantation and whether this affects the outcome with respect to graft versus host response.
Background: - Treatment for liver cancer can include surgery, transplant, and chemotherapy. It can also include other minimally invasive tumor treatments such as transarterial chemoembolization (TACE). TACE treatment for liver cancer helps control the cancer but is not considered a cure. Researchers want to learn more about the effects of TACE on liver tumors and surrounding tissue. To do this, they will use a positive emission test (PET) and a radioactive tracer called [18F] FMISO. Objectives: - To see if [18F] FMISO is useful for evaluating what happens to liver tumors and surrounding tissue after TACE. Eligibility: - People age 18 and older with liver cancer who have been approved to have TACE. Design: - Participants will meet with a study researcher to see if they can take part in the study. - Participants will have TACE under a separate NCI protocol or at a hospital other than the NIH Clinical Center. - Before and after TACE, participants will have a CT and MRI of the abdomen. For these scans, they will lie in a machine that takes pictures of their body. They will also have blood tests and a physical exam. - The [18F] FMISO imaging study will be performed at NIH only. - Participants will have an intravenous catheter placed in their arm (if they do not have one). The [18F] FMISO tracer will be injected. - Participants will have PET-CT scans. Each scan will take about 30 minutes. - Some participants will also have [18F] FMISO and PET-CT scans before TACE. - As part of standard care for TACE, participants will have CT and MRI scans at regular intervals. This will evaluate tumor response.
Estimation of functional liver reserve in patients with hepatocellular carcinoma (HCC) in cirrhosis is of paramount importance to properly select candidates for surgical resection. Together with the value of bilirubin, the presence/absence of ascites and esophageal varices, and the rate of residual liver volume, which are our current parameters to measure functional liver reserve, the investigators sought to investigate the value of preoperative cholinesterases (CHE) in predict postoperative adverse outcome after hepatic resection for HCC.
Patients with unresectable metastatic colorectal cancer confined to the liver will undergo a 1 hour hyperthermic isolated hepatic perfusion (IHP) with escalating dose melphalan. Postoperatively, patients will be treated with hepatic arterial infusion of floxuridine (FUDR), 0.2 mg/kg/day and leucovorin (LV), 15 mg/M2/day as a 2-week continuous infusion regimen. Hepatic and systemic toxicity, response to treatment, duration of response, and survival will be followed.
