Active clinical trials for "Carcinoma, Hepatocellular"

All Hepatocellular carcinoma and Renal cell carcinoma patients who receive molecular targeted therapy will be candidates for the study. No additional treatment or intervention will be conducted except for blood sampling that will be limited to one time only. Blood samples (10 cc in volume) will be collected from all study participants once they provided written informed consent form. DNA will be extracted from peripheral blood samples using DNA isolation kit.

Early stage HCC is treated by curative surgical resection or by local ablation (such as radio-frequency) as the current standard of care. The complete removal of clinical visible HCC is then confirmed by imaging by MRI or CT, or by a decline of tumor marker (AFP or PIVKA). However, despite an apparent complete removal of the HCC, those post-curative patients frequently develop tumor recurrence at a rate ranging 10-50% within the first year. The high rate of early HCC recurrence indicated a minimal residual HCC after the curative therapies in a significant proportion of patients. A better and more specific biomarker for detecting the residual HCC will improve the patients' prognosis prediction and therapeutic plan. To detect the minimal residual HCC, a biomarker unique to the tumor is needed. Currently, the cell-free circulating DNA carrying tumor-specific somatic mutations has been advocated as a promising one. It has been applied to investigate the tumor responses or resistances to cancer therapy. However, currently it is restricted to detect or follow only large advanced cancer, because of the difficulty in separating or enriching the cfDNA with tumor-specific mutations from the cfDNA from normal cells. In this project, the investigators proposed that one class of somatic mutation in HBV-related HCC, namely the insertion mutagenesis by integrated HBV DNA, could be adopted to circumvent this difficulty. HBV DNA integration has been found in the chromosomes of about 90% of HBV-related HCC and the integration site is unique to individual HCC. The HBV-host junction DNA fragment from one HCC is therefore a tumor-specific biomarker. Such fragments can be released into the circulation as cell-free circulating DNAs, and the detection of the HBV-host chimera DNAs in the circulation is a reliable evidence for the presence of the tumor in the patient. Therefore the cf circulating HBV-host chimera DNA is proposed to assay any minimal residual HCC after curative therapies.

Over the last 10 years, technological advances in molecular biology enabled a more accurate genomic characterization of tumors. For each tumor location, this led to the identification of subgroups with similar molecular characteristics. This identification allowed the development of targeted therapies and thus to improve the patient prognosis. This molecular characterization has also revealed the tumor heterogeneity. It may be the cause of treatment resistance and therefore of relapses. Additionally, tumor cells are in constant dialogue with their microenvironment composed of different immune or non immune cells. This microenvironment is now targeted in cancer treatment. To date, there are few studies that combine a deep genomic characterization of both tumor and tumor microenvironment of the patient. Combining the two types of studies on the same tumor should help to define new therapeutic targets and should allow a combination of targeted and immunomodulatory therapies. To this end, our project is to conduct an exhaustive integrated exploratory analysis at genomic, transcriptomic and immunological levels of 3 tumor types (in colon, kidney and liver cancer).

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.

All study objectives will be assessed in HCC patients or colorectal cancer patients with secondary metastases in the liver, respectively.

The purpose of this multicenter registry is to gather the safety, efficacy and survival data in intermediate and advanced HCC patients treated drug-eluting microsphere in Taiwan in order to provide clinical evidence in HCC management to physicians in the region, and to support the application of deTACE in treating advanced HCC patients.

The purpose of this study is to establish molecular subtyping of HCC.

It is a a single arm, observational clinical trial to evaluate the efficacy and safety of combination treatment with sintilimab injection plus endostar in untreated locally advanced or metastatic hepatocellular carcinoma.

The incidence of Hepatocellular carcinoma (HCC) is increasing worldwide. However, most of HCC cases were at advanced stage when the diagnosis established.Early diagnosis improves the prognosis.The study is intended to evaluate the diagnostic efficiency of alpha-fetoprotein-L3 (AFP-L3) and Protein Induced by Vitamin K Absence or antagonist-II (PIVKA-II). This study is performed at Hanoi Medical University Hospital. Participants including patients with HCC and hepatic hemangioma. All the serum samples are collected before any treatments and will be tested in single center in order to decrease bias. Serum samples were tested for PIVKA-II, AFP, AFP-L3 and biochemical indexes including alanine aminotransferase(ALT),aspartate aminotransferase (AST), gamma-glutamyl transferase, HbsAg, Anti HCV, etc.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, its survival rate ranks only second to lung cancer and it is a severe threat to human health. In Egypt, HCC constitutes a significant public health problem. Where it is responsible for 33.63% and 13.54% of all cancers in males and females respectively. It has a poor prognosis after discovery, which is usually at a late stage of disease. This had been strongly linked to the hepatitis C virus epidemic that affected around 10-15% of the Egyptian population during the last 3 decades, and was reported as the highest prevalence of HCV in the world. However, the pathophysiological mechanisms involved remain unclear. The occurrence of HCC is a complicated process involving multiple genes and steps. Imbalances in cellular signal transduction pathways, deficiencies in DNA repair regulating genes, activation of protooncogenes, inactivation of tumor suppressor genes and epigenetic modifications all promote the occurrence of liver cancer.
