Morphological change of foveolar-type gastric adenocarcinoma after proton pump inhibitor discontinuation in a short time period: A case report.

A 37-year-old man with systemic lupus erythematosus underwent esophagogastroduodenoscopy as a screening examination for anemia and bloody stool. A semi-pedunculated edematous lobular polyp of 25 mm in size was detected in the greater curvature of the upper gastric body. At that time, a definitive diagnosis of cancer could not be made based on a biopsy specimen from the lesion.

[Gastric varices treated by balloon-occluded retrograde transvenous obliteration following oxaliplatin-based chemotherapy for gastric cancer].

A 78-year-old female patient with stomach cancer (with hepatic metastasis and peritoneal dissemination) had received eight courses of an S-1 and oxaliplatin regimen as palliative chemotherapy. Computed tomography revealed liver deformities and incidental gastric varices. Esophagogastroduodenoscopy confirmed the findings of gastric varices in the cardia and fornix.

Influence of skeletal muscle volume loss during lenvatinib treatment on prognosis in unresectable hepatocellular carcinoma: a multicenter study in Tohoku, Japan.

Sarcopenia is associated with poor prognosis of patients with hepatocellular carcinoma (HCC). We investigated the association of skeletal muscle volume (SMV) and its change in HCC patients taking lenvatinib. In 130 HCC patients, psoas mass index (PMI) was calculated as the left-right sum of the major × minor axis of psoas muscle at the third lumbar vertebra, divided by height squared.

Safety and efficacy of glecaprevir and pibrentasvir in north Tohoku Japanese patients with genotype 1/2 hepatitis C virus infection.

Background And Aims: To assess the efficacy and safety of treatment with glecaprevir/pibrentasvir in Japanese patients with genotype (GT) 1/2 hepatitis C virus (HCV) infection in a real-world clinical setting.

Methods: A total of 230 patients from 12 centers in northern Tohoku Japan with chronic hepatitis (CH) or compensated liver cirrhosis (LC) and GT1/2 HCV infection were treated with glecaprevir/pibrentasvir and followed up for 12 weeks after treatment completion. Those patients were evaluated by dividing them into the following three groups: CH GT1/2 HCV-infected, direct-acting antiviral agents (DAA)-naive patients received 8 weeks of treatment (8-week initial treatment group), compensated LC GT1/2 HCV-infected, DAA-naive patients received 12 weeks of treatment (12-week initial treatment group), and GT1/2 HCV-infected patients with previous failed DAA treatment were assigned to 12-week treatment (12-week re-treatment group).

The utility of two-dimensional real-time shear wave elastography for assessing liver fibrosis in patients with chronic hepatitis C virus infection.

Objective: Two-dimensional shear wave elastography (2D-SWE) is a new ultrasound-based elastography method to evaluate liver fibrosis in the daily practice. However, the utility of 2D-SWE among the other liver fibrosis markers is unclear.

Methods: We enrolled 141 consecutive patients with hepatitis C virus infection, 66 men and 75 women (median age, 67 years), who underwent liver biopsy and 2D-SWE (LOGIQ E9, GE Healthcare, Wauwatosa, WI, USA).

Characteristics of printing company workers newly diagnosed with occupational cholangiocarcinoma.

Background: Cholangiocarcinoma has been reported in workers exposed to chlorinated organic solvents and has consequently been classified as an occupational disease (occupational cholangiocarcinoma) by the Japanese Ministry of Health, Labour and Welfare. This study aimed to identify the characteristics of nine workers newly diagnosed with occupational cholangiocarcinoma.

Methods: This study was a retrospective study conducted in 13 hospitals and three universities.
