Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

open access: yesVIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...

Apoptosis and proliferation in Helicobacter pylori-associated gastric intestinal metaplasia

open access: yes, 2001
Background: Imbalance between apoptosis and proliferation may be one of the mechanisms underlying H. pylori associated gastric carcinogenesis. Aim: To examine the cell kinetics of gastric intestinal metaplasia and the effect of H.

Prevalence of upper digestive endoscopy and gastric histopathology findings in morbidly obese patients

open access: yesArquivos de Gastroenterologia, 2012
CONTEXT: The prevalence of obesity has been increasing in modern society. Roux-en-y gastric bypass is a bariatric surgery that involves the exclusion of significant part of the stomach.

Intestinal Metaplasia and Gastric Carcinoma [PDF]

open access: yes, 1990
Previous studies have suggested that gastric carcinogenesis is a multistage process involving first gastritis, then intestinal metaplasia, dysplasia of increasing severity and finally carcinoma. The exact role of intestinal metaplasia in the histogenesis

Prevalence of High-Risk Groups for Gastric Carcinoma – A Biopsy Finding

open access: yesNepalese Medical Journal, 2018
Introduction: Gastric carcinoma is leading cause of death world wide including Nepal. The 5 years survival rate of gastric carcinoma (25%) has drastically decreased compared to early gastric cancers (90-90%) hence implying the need for early detection ...

Association of Helicobacter pylori vacA polymorphisms with the risk of gastric precancerous lesions in a Moroccan population

open access: yesJournal of Infection in Developing Countries, 2021
Introduction: Helicobacter pylori infection is the major risk factor of atrophic gastritis and intestinal metaplasia. The vacA gene is one of the most virulence factors of H.

Gastric Mucosal Molecular Alterations and Multimodal Field‐Based Risk Models for Gastric Cancer Development

open access: yesCancer Science, EarlyView.
DNA methylation in non‐neoplastic background gastric mucosa reflects cumulative inflammatory and exposure‐related field changes before cancer develops. Combining methylation with clinical, endoscopic, histological, and emerging multimodal information may refine calibrated gastric cancer risk prediction and support risk‐adapted personalized endoscopic ...

Unveiling the molecular profile of adenosquamous gallbladder carcinoma: characterization of a Caucasian cohort

open access: yesHistopathology, EarlyView.
GBASCs are MMRp tumours, exhibiting minimal HER2 overexpression and elevated PD‐L1 expression compared to adenocarcinomas. Especially in metastatic and TP53‐wild type tumours, GBASCs can express CLDN18, albeit limited to the glandular component. Their genomic profile resembles that of adenocarcinomas with an enrichment in alterations on PIK3CA, PTEN ...

When to consider an inborn error of immunity: clues for physicians

open access: yesInternal Medicine Journal, EarlyView.
Abstract The term inborn errors of immunity (IEIs) refers to the rapidly expanding group of genetic disorders causing dysregulation of the immune system. With improved genetic testing in recent years, the number of defined IEIs and their range of phenotypic presentations has grown vastly, with more than 550 IEIs now described.
