Interleukin-28B genotypes determine response to pegylated-interferon plus ribavirin therapy in patients with hepatitis C virus infection.

We recently reported that the interleukin (IL)-28B major genotype is a predictor of early suppression of the hepatitis C virus (HCV) at 12 weeks in response to pegylated interferon (PEG-IFN) plus ribavirin (RBV) therapy. The present study investigated the relationship between IL-28 genotypes and the virological response to PEG-IFN/RBV therapy at 24 and 48 weeks. Genotypes of the IL-28B rs8099917 T>G single nucleotide polymorphism were determined in 177 patients with HCV infection.

Interleukin-28B polymorphisms are associated with an early viral response in patients receiving hepatitis C therapy.

Prediction of the efficacy of pegylated interferon (PEG-IFN) plus ribavirin (RBV) therapy against hepatitis C (HCV) infection is valuable for determining its applications. This study investigated the relationship between the early response of HCV to PEG-IFN/RBV therapy and the inter-leukin (IL)-28B genetic polymorphism in patients with HCV infection. The genotypes of IL-28B rs8099917 T>G single nucleotide polymorphism were determined in 144 patients with HCV infection.

Evaluation of transcatheter arterial embolization therapy on hepatocellular carcinomas using contrast-enhanced harmonic power Doppler sonography: comparison with CT, power Doppler sonography, and dynamic MRI.

Purpose: The aim of this study was to assess and compare the sensitivity of power Doppler sonography, contrast-enhanced sonography, plain computed tomography (CT), and dynamic magnetic resonance imaging (MRI) for detecting hepatocellular carcinoma (HCC) nodules incompletely treated with transcatheter arterial embolization (TAE).

Methods: A total of 63 unresectable HCC nodules were examined in this study. The HCCs were treated with TAE.

[A case of advanced gastric cancer attaining histological CR of paraaortic lymph node after TS-1/CDDP neoadjuvant chemotherapy].

A 60-year-old male complaining of anemic symptoms went through examinations and was diagnosed with gastric cancer (cardia, type 3', cT2, cN3, cH0, cP0, cM0, cStage IV). Further inspection showed multiple lymph node metastases, including, No. 1, 3, 7, 11, and 16 (paraaortic LNs).

[A case of stomach cancer in which TS-1 neoadjuvant therapy was effective against multiple hepatic metastasis, allowing a radical cure A surgery].

It is believed that multiple hepatic metastases from stomach cancer are highly refractory, and resistant to clinical treatment. In the present study, TS-1 neoadjuvant therapy administered orally in a single course brought about CR in the hepatic metastatic foci and PR in the primary foci, thus enabling grade A radical extirpation in a case of advanced stomach cancer. The patient continued to be treated on an ambulatory basis.
