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.', 'detailedDescription': '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.\n\nThe 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.\n\nEpigenetics 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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '20 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Hepatocellular carcinoma patients', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* HCC treated with DAAs drugs for chronic hepatitis C in Assiut University Hospital.\n\nExclusion Criteria:\n\n* Cases who started treatment for HCC like alcohol ablation or chemoembolization\n* Hepatitis B infection\n* Non-responder patients to DAAs'}, 'identificationModule': {'nctId': 'NCT04220151', 'briefTitle': 'Epigenetic Changes in Hepatocellular Carcinoma Developed After Direct Acting Antiviral Therapy for Chronic Hepatitis C', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'Epigenetic Changes in Hepatocellular Carcinoma Developed After Direct Acting Antiviral Therapy for Chronic Hepatitis C', 'orgStudyIdInfo': {'id': 'Hepatocellular carcinoma'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Hepatocellular carcinoma', 'description': 'Sixty patients with HCC', 'interventionNames': ['Genetic: DNA methylation']}, {'label': 'Hepatic cirrhosis', 'description': 'Thirty patients with hepatic cirrhosis', 'interventionNames': ['Genetic: DNA methylation']}, {'label': 'Healthy controls', 'description': 'Ten healthy controls.', 'interventionNames': ['Genetic: DNA methylation']}], 'interventions': [{'name': 'DNA methylation', 'type': 'GENETIC', 'description': 'DNA methylation will be measured by real time polymerase chain reaction', 'armGroupLabels': ['Healthy controls', 'Hepatic cirrhosis', 'Hepatocellular carcinoma']}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'reham elmahdy', 'role': 'CONTACT', 'email': 'reham.elmahdy@aun.edu.eg', 'phone': '+201002714637'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assiut University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal Investigator', 'investigatorFullName': 'Reham I El-mahdy', 'investigatorAffiliation': 'Assiut University'}}}}
