Active clinical trials for "Carcinoma, Hepatocellular"

The aim of the multi-centre study is to evaluate correctly the impact of three dimensional visualization on operation strategy and complications for complex hepatic carcinoma.

Microvascular invasion (MVI) has been well demonstrated as an unfavorable prognostic factor for hepatocellular carcinoma (HCC), and patients with MVI have a high risk of tumor recurrence after curative hepatectomy. Currently, the diagnosis of MVI is determined on the postoperative histologic examination, which greatly limits its influence on preoperative decision making. Therefore, we constructed this prospective study to develop a machine learning-based model for preoperative prediction of MVI by extracting high-dimensional magnetic resonance (MR) image features.

The aim of this work is to study the role of circulating miRNAs in diagnosis of HCV related hepatocellular carcinoma.

In this project proposal, the investigators will investigate the genetic alterations of Hepatitis B Virus (HBV) strains circulating in Belgian patients who developed end stage liver disease. Additionally, the investigators will compare and link these data sets with three genetic factors involved in immune system response.

Circulating free cell DNA (cfDNA) is extracellular fragmentation of nucleic acids that occurs both in plasma and serum. This kind of DNA which derived from the apoptotic/necrotic cells or the lysis of circulating tumor cells (CTCs) can be detectedin the patients with a variety of diseases. Emerging evidence suggests that cfDNA from patients exhibits characteristicchanges of tumors, suchas mutations, insertions/deletions, methylations,microsatellite aberrations, and copy number variations, etc. All of these reveal a visible difference between the benign conditions, and thus may be useful in the diagnosis of cancer, identification of targeted therapy, monitor responses to treatments, and early detection of relapse. The purpose for this study is to explore these characteristic changes in the patients withhepatocellular carcinoma (HCC) and expect to guide targeted therapy and identify non-invasive biomarkers of cancer diagnosis and prognosis which can be easily isolated from the circulation.

The aims of this study were divided into three parts: To evaluate the sensitivity and specificity of GP73 for the diagnosis of hepatitis B related HCC. Established the standard of GP73 in normal people. To definitude the connections between the GP73 level and various diseases. To find the relations of HCC metastasis and recurrence. Study design: Collectivity type: Prospective，randomized, controlled, multi-central clinical study. Patients: The subjects were from different hospitals including: Peking Union Medical College Hospital (PUMCH), The Cancer Hospital of Peking Union Medical College (PUMC), QiDong Cancer Institute, and Department of Surgery University of Chicago from November of 2007 till the end of this study. Study arrangement: This study was consisted of three parts: Established the standard of normal people and test the sensitivity and specificity of HCC patients. The samples were acquired from Health Screen Center and Department of liver surgery of PUMCH, The Cancer Hospital of PUMC and QiDong Cancer Institute. Extend the study bound, including the hepatitis B virus (HBV) and hepatitis C virus (HCV) carriers. The HBV (+) samples were come from Chinese hospitals and institutions. The HCV (+) samples were provide by the Department of Surgery University of Chicago. Research the relations of serum GP73 level and the other diseases, such as other malignant liver tumors, liver metastatic tumors, liver benign tumor, HCC recurrence following surgery etc.

This study prospectively evaluates the accuracy of the noninvasive diagnostic criteria for hepatocellular carcinoma.

More recent studies have shown that the HBV-infected population has a greater risk of development of hepatocellular carcinoma. Nevertheless, there are still a significant number of people chronically infected by HBV who do not develop the complication. Hence, there exist biological markers that could be indicator for the disease-inducing and carcinogenic potential of the virus.

To assess the prognostic role of pretreatment LMR in hepatocellular carcinoma(HCC).

This cohort study compares immune response induced in two groups of small HCC patients treated by ablation (group1 RFA, group 2 MWA). Patients will benefit for tumoral and non tumoral biopsies prior to treatment and stepped peripheral blood samples juste before ablation and during the first month after.
