Primary liver cancer is one of the most common malignant tumor and leading cause of cancer-related death worldwide. Basically therapeutic strategies were considered and given based on the staging of liver cancer. Thus, the confirmatory diagnosis of numbers and distribution of malignant lesions were extreme important. Enhanced CT or MRI is routinely imaging scans to detect and identify lesions. Unfortunately, some malignant lesions usually presented untypical imaging characteristics, especially among lesions no larger than 1 cm, which misleading to the exact staging of liver cancer and the optimal therapeutic strategies. Basically most of blood supply for malignant liver tumors is from the hepatic artery. Based on this fact, hepatic arterial digital subtraction angiography could potentially elevate the accuracy and sensitivity of detection malignant lesions numbers and distribution. In this study the investigators will compare the numbers and distribution of malignant lesions before and after hepatic arteriography, then to revise the staging of liver cancer and to provide better therapeutic strategies.
Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumor and has a grave prognosis. Obesity is an epidemic in the US.Patients with HCC and obesity are not candidates for liver transplantation, depriving them of the best option for cure from HCC. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss.The purpose of this study is to determine if Left gastric artery embolization (LGAE) in patients with cirrhosis and HCC who are not transplant candidates due to morbid obesity, leads to clinically significant weight loss with eligibility for liver transplantation.
Hepatocellular carcinoma (HCC) is the most frequent primary tumour of the liver and is the third cause of cancer-related mortality worldwide. Depending on the stage of the disease, the treatment options are surgery, liver transplantation, chemotherapy or radiotherapy. Recently, scientific research has focused on small molecules called microRNAs which are produced by human cells and can be released in the blood. They have a role in cell proliferation and are found to be dysregulated in different types of cancer. It has been shown that microRNAs have a role in the development of HCC but it is unknown if these molecules can be used as markers for diagnosis and survival in HCC. In particular, microRNAs miR-221 and miR-222 are dysregulated in the tumoral tissues in about 80% of patients with HCC. This can be assessed on tissues from liver biopsies or surgical specimens, both invasive approaches. Only few studies showed the presence of microRNAs in the blood of patients with HCC but it is unknown if there is a correlation between tumoral tissue expression and circulating levels. The aim of this study is to evaluate if these two microRNAs are expressed not only in the tumoral tissues but also in the blood from cancer patients, and in different amounts compared to circulating levels in healthy individuals. A correlation between tumoral tissue and blood levels will also be evaluated. Should this evaluation show a strong correlation and reliability of circulating microRNAs in the diagnosis and follow up of HCC, future clinical trials targeting these microRNAs and their related pathways might benefit from this being adopted as conventional practice instead of the need of assessing tissue levels from liver biopsies. The results of this pilot study will bring preliminary results as a first step for future analysis on a larger cohort of patients.
Clinical research of Yang Yin Fu Zheng therapy in HBV associated hepatocellular carcinoma basing on immune microenviroment.The purpose of this study is to observe the efficacy of routine medical care combined with Yang Yin Fu Zheng therapy for patients belong to HBV-HCC.
Till now, trans-arterial chemoembolization (TACE) is still one of the common modalities in treating hepatocellular carcinoma patients with unresectable intermediate stage. However, residual viable HCC after TACE is not uncommon, leading to a poor overall survival after TACE alone. Recently, stereotactic ablative radiotherapy (SABR) has been reported to be potentially useful for curatively managing early-stage HCC in retrospective studies. Thus, conducting a randomized clinical trial to test the role of SABR in eradicating post-TACE residual tumors is therefore encouraged. The present phase-III trial intended to compare clinical outcomes between TACE + SABR and TACE + re-TACE for HCC patients with post-prior-TACE residual tumors.
Patients having surgery to remove a liver or biliary tissue mass will have a tissue sample collected and stored for future research. A blood sample may also be collected at the time of enrollment.
The study will be a single-center, randomized Phase II study of conventional TACE in combination with sorafenib, given either continuously or sequentially, in patients with unresectable HCC. The primary variables will be tumor response (by MR Imaging) and plasma VEGF levels, prior to and after cTACE.
The study will examine and evaluate the use of extracellular RNA in blood as markers for the diagnosis of liver disease or cancer, and as markers for prediction of response to treatment or recurrence of cancer after surgery
This study enrolls patients who have a type of cancer that arises from the liver called hepatocellular carcinoma. The cancer has come back, has not gone away after standard treatment or the patient cannot receive standard treatment. This research study uses special immune system cells called GLYCAR T cells, a new experimental treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting blood cells that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. Investigators have found from previous research that they can put a new gene into T cells that will make them recognize cancer cells and kill them. In preclinical studies, the investigators made several genes called a chimeric antigen receptor (CAR), from an antibody called GC33 that recognizes glypican-3, a protein found on almost all hepatocellular carcinoma cells (GPC3-CAR). This study will test T cells genetically engineered with a GPC3-CAR (GLYCAR T cells) in patients with hepatocellular carcinoma. The GLYCAR T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the biggest dose of GLYCAR T cells that is safe, to see how long they last in the body, to learn what the side effects are and to see if the GLYCAR T cells will help people with GPC3-positive hepatocellular carcinoma.
Liver cancer is one of the leading causes of cancer death among Asian men. If diagnosed early the disease is treatable with surgery. Current conventional imaging modalities have limitations to early detection. This study proposes to use 18F-FGal and 18F-FDG PET/CT scans to compare the clinical efficacy of diagnosing hepatocellular carcinoma (a type of liver cancer) using these PET/CT scans.
