About this study

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.

Read the detailed description

HCC is the fourth leading cause of cancer mortality in 2018. The alarming incidence of HCC is explained by genetic and epigenetic alterations, as well as by the presence of risk factors: hepatitis C virus (HCV), hepatitis B virus (HBV) infection, alcohol consumption, smoking, diabetes, dietary exposure to aflatoxins, and obesity.

The development of direct-acting antivirals (DAAs) with cure rates of higher than 90% has been a major breakthrough in the management of patients with chronic HCV infection. However, although viral cure decreases the overall HCC risk in HCV-infected patients, it does not eliminate virus-induced HCC risk, especially in patients with advanced fibrosis. Furthermore, convenient biomarkers to robustly predict HCC risk after viral cure and strategies for HCC prevention are absent. These unexpected findings pose new challenges for patient management. Meanwhile, recent studies in patients treated with interferone-free therapy have also identified several risk factors for developing HCC after achieving sustained virological response (SVR), namely advanced hepatic fibrosis and higher levels of alpha feto protein and agglutinin-positive Mac-2 binding protein.

Epigenetics refers to inherited altered gene expression without an alteration of the DNA sequence itself. Epigenetic alterations, such as DNA hypomethylation or hypermethylation and aberrant expression of micro-RNAs have been studied and associated with HCC. Epigenetic changes may represent diagnostic and prognostic biomarkers of HCC.

An observational study of Hepatocellular Carcinoma, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact reham elmahdy (+201002714637, reham.elmahdy@aun.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentages of methylation of DNA in patients with HCC (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04220151, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2020.
