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.

Airway disorders associated with immune checkpoint inhibitor therapy: Two case reports and a systematic review.

Immune checkpoint inhibitors (ICI) are widely used for the treatment of various malignant neoplasms. Interstitial lung disease is a well-known immune-related adverse event, however, ICI-induced airway disease remains under-recognized. Herein, we report two similar cases of pembrolizumab-induced tracheobronchitis presenting as persistent chronic cough and dyspnea.

Non-inferior clinical outcomes of immune checkpoint inhibitors in non-small cell lung cancer patients with interstitial lung disease.

Objectives: The efficacy of immune checkpoint inhibitors (ICIs) in non-small-cell lung cancer (NSCLC) patients with pre-existing interstitial lung disease (ILD) is unclear.

Materials And Methods: Retrospective medical data from advanced or recurrent NSCLC patients who were treated with nivolumab or pembrolizumab at ten institutions in Japan between January 2016 and September 2018 were analyzed. Eligible patients were divided into two groups according to the presence of pre-existing ILD.

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).
