Active clinical trials for "Carcinoma, Hepatocellular"

The goal of this single-arm prospective study is to evaluate the application of serum DNA methylation for HCC patients with normal alpha-fetoprotein. The main question it aims to answer is . Is the dynamic change of serum DNA methylation correlated to recurrence or treatment response of HCC

This early phase I trial evaluates the use of hypoxia (lack of oxygen) as a measure in determining the outcome of Y90 selective internal radiation therapy in patients with liver cancer that has spread to a limited number of sites (oligometastatic). Radioembolization with Y90 is a minimally invasive procedure that combines embolization and radiation therapy to treat metastatic liver cancer. Tiny beads filled with radioactive isotope Y-90 are placed inside the blood vessel that provide blood supply to the tumor. This will block the blood flow to the tumor cells while providing a high radiation dose without harming healthy normal tissue.

The purpose of the study is to determine if the type of catheter used in the mapping procedure prior to radioembolization improves the delivery of radioactivity to tumor(s) in participants with liver cancer. The name of the devices involved in this study are: Pressure Enabled Drug Delivery (PEDD)/TriNav Infusion System Standard 2.4F microcatheter, not otherwise specified

This clinical trial studies fluorine F 18 L-glutamate derivative BAY94-9392 (18F-FSPG) positron emission tomography (PET) in imaging patients with liver cancer before undergoing surgery or transplant. Diagnostic procedures, such as 18F-FSPG PET, may help find and diagnose liver cancer and find out how far the disease has spread.

All international guidelines recommend 6-monthly ultrasound surveillance for patients at risk for liver cancer (hepatocellular carcinoma or HCC), such as patients with cirrhosis. The aim of surveillance is to detect HCC at an early stage when it is still potentially curable. Currently only 4 out of 10 HCCs are detected at the early stage. Ultrasound surveillance for HCC has a wide ranging sensitivity, dependent on many factors such as operator experience, patient body habitus and liver parenchymal heterogeneity due to chronic liver disease and cirrhosis. In a select group of patients, surveillance ultrasound can be suboptimal or near non-diagnostic. Currently no guideline offers an alternative surveillance tool for patients who have suboptimal surveillance ultrasounds.

This trial studies how well an investigational scan (magnetic resonance elastography [MRE]) works with standard imaging (magnetic resonance imaging [MRI]) in detecting response to treatment in patients with liver cancer that has spread to other places in the body. Diagnostic procedures, such as MRE with MRI, may make it easier for researchers to see if the treatment for liver cancer is working.

This clinical trial evaluates whether 68Ga-PSMA PET/MRI or PET/CT can improve upon the diagnosis and management of liver cancer. MRI stands for magnetic resonance imaging, a scan that uses magnetic and radio waves to produce detailed structural information of the organs, tissues and structures within the body. PET stands for positron emission tomography, an imaging test that helps to measure the information about functions of tissues and organs within the body. A PET scan uses a radioactive drug (radiotracer) to show this activity. CT scan uses X-rays to create images of the bones and internal organs within the body. In patients that have been diagnosed with liver cancer, a protein called prostate specific membrane antigen (PSMA) appears in large amounts on the surface of the cancerous cells. The radioactive chemical compound (68Ga-PSMA) has been designed to circulate through the body and attach itself to the PSMA protein on liver cancer cells. 68Ga-PSMA PET/MRI or PET/CT may be better in diagnosing and managing liver cancer.

Background: A radiotracer (or tracer) is a radioactive substance. It is used in Positron Emission Tomography (PET) imaging to help see specific sites in the body. Researchers want to learn if a new tracer can help them better identify hepatocellular cancer (HCC) in people. Objective: To learn if a radiotracer called 18F-DCFPyL can identify sites of HCC better than current standard imaging. Eligibility: Adults aged 18 years and older who may have HCC based on previous standard imaging. Design: Participants will be screened with a medical history, physical exam, and blood tests. They will have a computed tomography (CT) and/or magnetic resonance imaging (MRI) scan. Participants will have a whole-body PET/CT scan. The PET and CT scanners use x-rays to make pictures of the inside of the body. The PET uses a tracer to help make the pictures. Participants will get an intravenous (IV) injection of 18F-DCFPyL 1 hour before the scan. Within two weeks, participants will have a 18F-FDG PET/CT scan. 18F-FDG is a commonly used tracer. They will get 18F-FDG via IV 1 hour before the scan. Participants will have a CT/MRI within 2 months of the first 18F-DCFPyL PET/CT. Participants will have standard treatment for their cancer. During treatment, they will have a tumor biopsy. If the biopsy shows they do not have HCC, they will be removed from the study. For participants who have HCC and their cancer was identified in the 18F-DCFPyL PET/CT, they will have a second 18F-DCFPyL PET/CT and 18F-FDG PET/CT. Participants will have follow-up visits every 3 months for 2 years. Then they will have yearly visits for 3 years....

The purpose of this study is to evaluate whether statin could prevent recurrence of hepatocellular carcinoma after curative treatment

Most patients undergoing hepatectomy for hepatocellular carcinoma (HCC) suffer from underlying liver disease and are exposed to the risk of postoperative ascites, with subsequent morbidity, liver and renal failure, the need for specific treatments and prolonged hospital stay. Postoperative ascites is favored by an imbalance between portal venous inflow and the diminished hepatic venous outflow. Finding a reversible, non-invasive method for modulating the portal inflow would be of interest: it could be used temporarily during the early postoperative course to prevent acute portal hypertension. Somatostatin, a well-known drug already used in several indications, may limit the risk of postoperative ascites and liver failure by decreasing portal pressure after hepatectomy for HCC in patients with underlying liver disease.
