[A Case of Resection of T2N0 Colon Cancer with Synchronous Solitary Lung Metastasis].

A 73-year-old man was referred to our hospital for anemia. He underwent a colonoscopy; a 15-mm Ip polyp and a 30- mm type 1 lesion were found in the sigmoid colon. Pathological examination results indicated a well-differentiated adenocarcinoma.

Weight-based high- and low-dose ribavirin in combination with peginterferon α-2b therapy for genotype 2 chronic hepatitis C: A randomized trial.

Aim:   The optimal ribavirin dose in the treatment of patients infected with hepatitis C virus (HCV) genotype 2 remains to be elucidated. We aimed to seek the optimal ribavirin dose required for this genotype in a randomized trial.

Methods:   We compared the efficacy and tolerability of the 24-week peginterferon α-2b (1.

Differential impact of adherence to pegylated interferon and ribavirin in the treatment of genotype 1 high viral titer chronic hepatitis C.

To clarify the impact of adherence, we treated 122 genotype 1 high viral titer chronic hepatitis C patients with pegylated interferon (peg-IFN) and ribavirin for 48 weeks at nine referral hospitals, and evaluated the prognostic factors with a focus on the adherence to the treatment. This study included 68 (55.7%) treatment-naïve patients and 54 (44.

Hemophagocytic syndrome in ileum-origin B-cell lymphoma.

A 56 year-old-man was admitted due to upper abdominal tumor and was diagnosed as having stage IVb diffuse B-cell malignant lymphoma that originally developed in the terminal ileum. The first and the second administrations of CHOP (cyclophosphamide, 750 mg/m(2); adriamycin, 50 mg/m(2); vincristine, 1.4 mg/m(2); and prednisolone, 100 mg/day) therapy were effective; however, the third course of therapy was postponed because of an episode of massive hematochezia.

Overexpression of the thrombospondin 2 (TSP2) gene modulated by the matrix metalloproteinase family expression and production in human colon carcinoma cell line.

Thrombospondin 2 (TSP2) is an extracellular matrix glycoprotein involved in tumor progression and angiogenesis. We evaluated whether overexpression of the TSP2 gene show an alteration of various genes by cDNA arrays in the colon carcinoma cell line SW480. The transformants with the human TSP2 gene overexpression showed a down-regulation of matrix metalloproteinase 2 (MMP2) and MMP9 in comparison to those with vector-control.
