Research Design And Methods: This is a retrospective data analysis of 523 HCV patients who have a history of successfully ablated HCC and eligible for HCV treatment.

Hepatocellular Carcinoma in Sub-Saharan Africa.

More than 80% of global hepatocellular carcinoma (HCC) patients are estimated to occur in sub-Saharan Africa (SSA) and Eastern Asia. The most common risk factor of HCC in SSA is chronic hepatitis B virus (HBV) infection, with the incidence highest in West Africa. HBV is highly endemic in SSA and is perpetuated by incomplete adherence to birth dose immunization, lack of longitudinal follow-up care, and impaired access to antiviral therapy.

Patients And Methods: This is a prospective study, including 179 HCV-related HCC patients. All patients were treated following the BCLC guidelines.

Genetic variations in DNA-repair genes (XRCC1, 3, and 7) and the susceptibility to hepatocellular carcinoma in a cohort of Egyptians.

Chronic hepatitis C (CHC) is a worldwide etiology of chronic hepatic insult particularly in Egypt. DNA-repair systems are responsible for maintaining genomic integrity by countering threats posed by DNA lesions. Deficiency in the repair capacity due to genetic alterations in DNA-repair genes can lead to genomic instability and increased risk of cancer development.

Genetic variations in death receptor domain 4 gene and the susceptibility to hepatitis C related hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer mortality worldwide, particularly in Egypt. The role of apoptosis in tumorigenesis has been well-documented and resistance to apoptosis is a hallmark of cancer. Several studies discussed the association between death receptor 4 (DR4) genetic variants and HCC risk.

Planning and prioritizing direct-acting antivirals treatment for HCV patients in countries with limited resources: Lessons from the Egyptian experience.

Background And Aims: The introduction of direct-acting antivirals for hepatitis C virus (HCV) in Egypt led to massive treatment uptake, with Egypt's national HCV treatment program becoming the largest in the world. The aim of this paper is to present the Egyptian experience in planning and prioritizing mass treatment for patients with HCV, highlighting the difficulties and limitations of the program, as a guide for other countries of similarly limited resources.

Methods: Baseline data of 337,042 patients, treated between October 2014 to March 2016 in specialized viral hepatitis treatment centers, were grouped into three equal time intervals of six months each.

Transarterial Chemoembolization Combined with Either Radiofrequency or Microwave Ablation in Management of Hepatocellular Carcinoma.

Introduction: Local ablative therapy and trans arterial chemoembolization (TACE) are applied to ablate non resectable hepatocellular carcinoma (HCC). Combination of both techniques has proven to be more effective. We aimed to study combined ablation techniques and assess survival benefit comparing TACE with radiofrequency (RFA) versus TACE with microwave (MWA) techniques.

Interferon-γ and Interleukin-10 Gene Polymorphisms are not Predictors of Chronic Hepatitis C (Genotype-4) Disease Progression.

Immunoregulatory cytokines have an influence on hepatitis C virus (HCV) infection outcome. This study aimed to determine whether single nucleotide polymorphisms (SNP) in IFN- γ and IL-10 genes are associated with susceptibility and/or are markers of prognosis regarding chronic hepatitis C outcomes. IFN γ (+874T/A) and IL-10 (-1082G/A) genotypes were determined in 75 HCV genotype 4 patients with different disease severities (chronic hepatitis, n=25, liver cirrhosis and hepatocellular carcinoma (HCC) on top of liver cirrhosis, n=50) and 25 healthy participants using allele-specific polymerase chain reaction.

Microwave ablation versus transarterial chemoembolization in large hepatocellular carcinoma: prospective analysis.

Objective: Limited therapies are offered for large hepatocellular carcinoma (HCC). It carries dismal prognosis and efforts tried changing its management from a palliative to a curative mode. Transarterial chemoembolization (TACE) is a palliative procedure that may have survival benefit if compared to non-management of large lesions.

Survival and prognostic factors for hepatocellular carcinoma: an Egyptian multidisciplinary clinic experience.

Background: Hepatocellular carcinoma (HCC) is a dismal tumor with a high incidence, prevalence and poor prognosis and survival. Management of HCC necessitates multidisciplinary clinics due to the wide heterogeneity in its presentation, different therapeutic options, variable biologic behavior and background presence of chronic liver disease. We studied the different prognostic factors that affected survival of our patients to improve future HCC management and patient survival.

Dynamic interplay between CXCL levels in chronic hepatitis C patients treated by interferon.

Background: Combined pegylated interferon-α and ribavirin therapy has sustained virological response (SVR) rates of 54% to 61%. Pretreatment predictors of SVR to interferon therapy have not been fully investigated yet. The current study assesses a group of chemokines that may predict treatment response in Egyptian patients with chronic HCV infection.

The Core/E1 domain of hepatitis C virus genotype 4a in Egypt does not contain viral mutations or strains specific for hepatocellular carcinoma.

Background: Hepatitis C virus (HCV) infection is a well-documented etiological factor for hepatocellular carcinoma (HCC). As HCV shows remarkable genetic diversity, an interesting and important issue is whether such a high viral genetic diversity plays a role in the incidence of HCC. Prior data on this subject are conflicting.

Lack of association between genotypes and subtypes of HCV and occurrence of hepatocellular carcinoma in Egypt.

The distribution of hepatitis C virus (HCV) genotypes was evaluated in individuals with hepatocellular carcinoma (HCC) and cirrhosis in Egypt. A total of 206 patients sero-positive for HCV-RNA among 400 surveyed individuals (186 with HCC, 100 with cirrhosis, and 114 healthy volunteers) were analyzed for HCV genotype. Of 206 patients, 129 had HCC, 65 had cirrhosis without HCC, and 12 were healthy volunteers.
