Active clinical trials for "Carcinoma, Hepatocellular"

This is a pilot, monocentric, prospective, randomized control trial looking at the use of rapid tests as a part of normal care. The investigators will be testing for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). Testing will be proposed to all persons seeking care at the Centre d'Accueil, de Soins et d'Orientation from the organization Médecin du Monde (CASO, MDM). Infection status of participants will be determined by either the standard test (ELISA) or rapid test. The choice between tests will be determined randomly. The overall goal is to determine the general acceptability and feasibility of rapid tests and to see if they can help individuals increase their awareness of infection status when compared to longer, routine methods of testing. In addition, results from these tests will allow the medical doctor to guide participants to appropriate care. All positive tests will be confirmed at a specialized hospital (Hôptial Saint-Antoine, Paris, France) and health-specific information will be obtained four months after testing.

This study aims to compare the role of peginterferon α-2b (50 μg/week) vs. control (no treatment) in the prevention of hepatocellular carcinoma, in adult patients with cirrhosis and initial signs of portal hypertension who did not respond to previous combined therapy with interferon alfa + ribavirin or peginterferon alfa + ribavirin or to interferon alfa monotherapy and with a high proliferation rate before entering the study. The duration of treatment will be 3 years, and the follow-up period will be 2 years.

This clinical trial studies positron emission tomography (PET)/computed tomography (CT) in diagnosing patients with liver cancer undergoing surgical resection. Diagnostic procedures, such as fluorine-18 fluoromethylcholine PET/CT, may help find and diagnose liver cancer.

Hepatocellular carcinoma (HCC) is a common malignancy with poor prognosis worldwide. The asymptomatic of early-stage HCC may lead most patients diagnosed at advanced stages. This highlights the importance of HCC screening among high-risk populations to detect HCC at early stages and achieve better survival. Hepatitis B virus (HBV) infection is a major cause of HCC in China, but the utilization of HCC screening is suboptimal among patients with HBV infection. Currently, there are no-theory based intervention, to our knowledge, has been reported to improve HCC screening decision-making and uptake among patients with HBV infection . Therefore, based on our previous systematic review, the current study has proposed a nurse-led decision counseling program to improve decision-making and uptake of HCC screening among patients with HBV infection in mainland China. Participants in intervention group will receive nurse-led decision counseling. The intervention components include 40-minute education and tailored information regarding HCC screening. At the second week, decision support will be provided through 30-minute telephone call. At the third week, another telephone call (20 minutes) will be provided to help participants identify and address barriers to HCC screening. Participants in control group will receive usual care. After the intervention and at 3-month follow-up, the study will collect data related to HCC screening uptake rates. Findings are paramount to promote informed choice in HCC screening and early HCC detection to improve survival outcomes among patients with HBV infection.

HCC is a serious threat to the health of people. Accurate diagnosis of early HCC by imaging allows patients to obtain proper treatment. However, for lesions with diameters ≤2 cm, the tumor blood supply is not fully established, and there may be no typical manifestation on the image. In addition, atypical enhanced patterns caused by liver cirrhosis may also hinder imaging diagnosis of HCC. Therefore, early diagnosis of HCC in the context of cirrhosis remains a major clinical problem. Contrast-enhanced Ultrasound (CEUS) and MRI Contrast-enhanced Magnetic Resonance Imaging (CEMRI) are common diagnostic imaging methods. Till now, there is still lack of a detailed investigation comparing the diagnostic efficacies of CEUS and EOB-MRI for micro HCC in the context of cirrhosis. Therefore, this study aims to analyze the imaging patterns in CEUS and EOB-MRI for liver lesions with diameters ≤ 2 cm among patients with high risk of HCC, and to compare the diagnostic efficacies of EOB-MRI and CEUS for early-stage HCCs.

Non-anatomical liver resection with appropriate resection margin was regarded as a potential curative treatment for selected major hepatic carcinoma due to preserving maximal normal liver, especially in cirrhotic patients. But occurrence of cutting surface related complications become a main challenge.

The incidence of hepatocellular carcinoma (HCC) has recently increased in the United States. Although imaging plays a major role in HCC screening and staging, the possibility of predicting HCC tumor grade, aggressiveness, angiogenesis and hypoxia with imaging are unmet needs. In addition, new antiangiogenic drugs now available to treat advanced HCC necessitate the use of new imaging criteria beyond size. The investigators would like to develop and validate non-invasive magnetic resonance imaging (MRI) methods based on advanced diffusion-weighted imaging (DWI), MR Elastography, BOLD (blood oxygen level dependent) MRI and perfusion-weighted imaging (PWI, using gadolinium contrast) to be used as non-invasive markers of major histopathologic features of HCC, and to predict and assess early response of HCC to systemic therapy. The investigators also would like to develop quality control tools to improve the quality and decrease variability of quantitative MRI metrics. These techniques combined could represent non-invasive correlates of histologic findings in HCC, could enable individualized therapy, and provide prognosis in patients with HCC.

The purpose of this study is to prospectively determine the diagnostic value of Xenetix-CT perfusion for the discrimination between well-differentiated hepatocellular carcinomas (HCC) and poorly/moderately differentiated HCC, in histo-pathologically proven HCC, and with the aim to cover the entire liver.

Ultrasound guided percutaneous ethanol injection (PEI) is an established method in the treatment of hepatocellular carcinoma (HCC) and considered a safe procedure with severe complications occurring rarely. Previous studies revealed, that the occurrence of bradycardia and sinuatrial blockage is quite frequent during ethanol instillation sometimes accompanied by clinical complications such as unconsciousness, respiratory arrest or seizure like symptoms. Study purpose is to evaluate whether the use of i.v. Atropine before starting ethanol instillation can prevent dysrhythmias during instillation. Study design: randomized, placebo controlled, double blinded study. Atropine or saline solution will be administered intravenously to 40 patients immediately before starting percutaneous ethanol instillation. A 6 line ECG with limb leads will be recorded at rest and during ethanol instillation to reveal possibly occurring dysrhythmias.

The purpose of this study is to prospectively analyze the value of 3D ultrasound perfusion imaging for treatment planning, the prediction of therapy success, and to monitor the treatment response in patients with a primary or metastatic liver tumor undergoing radiation treatment.
