Advanced liver fibrosis effects on the response to sofosbuvir-based antiviral therapies for chronic hepatitis C.

Background: Sustained virological response (SVR) rates for the treatment of chronic hepatitis C virus (HCV)-infected patients have drastically improved with the use of direct-acting antiviral (DAA) therapies; however, a small minority of patients still fails to eradicate the virus. We analyzed factors associated with SVR in DAA therapy and the effect of age and liver fibrosis on treatment response.

Methods: Nine hundred and eighteen patients with chronic HCV infection were treated with 24 weeks of daclatasvir plus asunaprevir (DCV + ASV) or 12 weeks of sofosbuvir plus ledipasvir (SOF + LDV), ombitasvir, paritaprevir plus ritonavir (OMB + PTV + r) or sofosbuvir plus ribavirin (SOF + RBV).

Hepatic arterial infusion chemotherapy followed by sorafenib in patients with advanced hepatocellular carcinoma (HICS 55): an open label, non-comparative, phase II trial.

Background: In patients with advanced hepatocellular carcinoma (HCC), evidence is unclear as to whether hepatic arterial infusion chemotherapy (HAIC) or sorafenib is superior. We performed a prospective, open-label, non-comparative phase II study to assess survival with HAIC or HAIC converted to sorafenib.

Methods: Fifty-five patients were prospectively enrolled.

However, the effect of ITPA polymorphism on sofosbuvir plus RBV treatment is unknown.

Methods: Two hundred and forty-four patients with chronic HCV genotype 2 infection without decompensated liver cirrhosis were treated with sofosbuvir plus RBV for 12 weeks.

Comparison of Outcome of Hepatic Arterial Infusion Chemotherapy and Sorafenib in Patients with Hepatocellular Carcinoma Refractory to Transcatheter Arterial Chemoembolization.

Aim: To compare the outcome of 5-fluorouracil (FU)-based hepatic arterial infusion chemotherapy (HAIC) with sorafenib monotherapy in patients with hepatocellular carcinoma (HCC) refractory to transcatheter arterial chemoembolization (TACE).

Patients And Methods: In this retrospective cohort study, 123 patients with HCC refractory to TACE, with Child-Pugh A and free of extrahepatic metastasis, were divided into two groups: 65 received HAIC and 58 received sorafenib. Since the size of main tumor and portal vein invasion were significantly different between the HAIC and sorafenib groups, we selected 48 patients from the 65 patients of the HAIC group and 48 from the 58 patients of the sorafenib group.

A preliminary prospective study to compare the diagnostic performance of assist strain ratio versus manual strain ratio.

Objectives: The objectives of this study were to demonstrate the non-inferiority of assist strain ratio (ASR)-a newly developed application tool-to manual strain ratio (MSR)-a currently available standard diagnostic tool-and to calculate the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MSR and ASR.

Balloon-occluded retrograde transvenous obliteration of gastric varix with multiple drainage veins performed with temporal occlusion of the pericardiacophrenic vein with a micro-balloon.

We encountered a case with a gastric varix that drained into the gastro-renal shunt, left pericardiacophrenic vein, and several other dilated collateral veins. This patient had a circumaortic venous ring. For this case we successfully performed balloon-occluded retrograde transvenous obliteration in which sclerotic agents were infused from the balloon catheter advanced to the left pre-aortic renal vein and the tip was wedged into the end of the gastro-renal shunt.

Comparison of hepatic arterial infusion chemotherapy versus sorafenib monotherapy in patients with advanced hepatocellular carcinoma.

Objectives: Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC) with distant metastasis, unresectable HCC, and those refractory to transcatheter arterial chemoembolization (TACE) or with macroscopic vascular invasion (MVI). The application of sorafenib has been approved by the Japanese Government-sponsored Medicare for unresectable HCC. In this retrospective cohort study we aimed to compare various aspects of HAIC with sorafenib in the treatment of Child-Pugh A patients with advanced HCC who were otherwise free of extrahepatic metastasis.
