简要总结

Direct acting antivirals (DAAs) are a novel and completely oral hepatitis C therapy . DAAs are used in most patients being treated for hepatitis C, including those with decompensated cirrhosis. This type of treatment has now completely replaced interferon-based therapy .Therapy of chronic hepatitis C with direct-acting antivirals (DAAs) is able to induce a sustained virological response (SVR) in over 85% of patients, even if liver cirrhosis is present. Cirrhotic patients should be closely monitored after treatment.HCC is thought to develop over time as the liver is exposed to inflammation and develops fibrosis. Thus, if DAAs can eliminate inflammation mediated by HCV, the risk of HCC should decrease. However, several centers have observed that this actually may not be the case. Tumor genesis occurs through a multistep, multifactorial process. Eliminating HCV-induced inflammation may not be enough to decrease risk of HCC.DAAs have provided an effective, well tolerated treatment for hepatitis C in patents with cirrhosis . However, several studies have shown unexpectedly high rates of recurrence of HCC in the early post DAAs treatment time period.

  1. Evalution of occurrence and risk factors for hepatocellular carcinoma (HCC) in patients with HCV-related liver cirrhosis after direct acting antiviral drugs (DAAs) therapy.
  2. To asses diagnostic value of novel markers in patients who developed hepatocellular carcinoma (HCC) after (DAAs)

详细描述

HCV is a worldwide infection, it is estimated that about at about 3.0% (170-200 million people) of the world's population are infected. HCV is associated with an increased disease burden due to liver cirrhosis and considerable mortality . More than 350,000 people dying each year from hepatitis C-related liver disease. Adding to the problem of HCV infection is the presence of occult HCV infection.

Egypt has the highest prevalence worldwide, it is estimated to be 14.7% among a representative sample of Egyptian population, aged 15-59 year . Egypt is among countries responsible for 80.0% of global infections. Further, prevalence is higher among hospitalized patients and special clinical populations.

Hepatitis C virus (HCV) has great genetic variability, with 6 major genotypes (GTs); GT-1 to 6. In Egypt, HCV is almost exclusive GT-4 distribution. HCV has significant differences in their global distribution and prevalence.

Worldwide, Hepatocellular carcinoma (HCC) is the fifth most common cancer in men and the seventh in women. Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death worldwide and one of the leading causes of death among patients with cirrhosis. In Egypt, HCC is the second most common cancer in men and the sixth most common cancer in women.

Direct acting antivirals (DAAs) are a novel and completely oral hepatitis C therapy . DAAs are used in most patients being treated for hepatitis C, including those with decompensated cirrhosis. This type of treatment has now completely replaced interferon-based therapy .Therapy of chronic hepatitis C with direct-acting antivirals (DAAs) is able to induce a sustained virological response (SVR) in over 85% of patients, even if liver cirrhosis is present. Cirrhotic patients should be closely monitored after treatment.
