Dynamic expression of CEACAM7 in precursor lesions of gastric carcinoma and its prognostic value in combination with CEA

open access: yesWorld Journal of Surgical Oncology, 2011
Background The significance of carcinoembryonic antigen-related cell adhesion molecule 7 (CEACAM7) expression in gastric carcinoma and precancerous lesions and its correlation with CEA expression has rarely been previously investigated.

Helicobacter pylori in Iran: a systematic review on the association of genotypes and gastroduodenal diseases [PDF]

open access: yes, 2012
Background: Helicobacter pylori (H. pylori) infection is known as a major etiologic factor for a variety of gastroduodenal diseases. In Iran, with a high rate of H. pylori infection close to 90%, numerous studies have revealed many aspects of interaction

Acute WNT signalling activation perturbs differentiation within the adult stomach and rapidly leads to tumour formation [PDF]

open access: yes, 2013
A role for WNT signalling in gastric carcinogenesis has been suggested due to two major observations. First, patients with germline mutations in adenomatous polyposis coli (APC) are susceptible to stomach polyps and second, in gastric cancer, WNT ...

Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

p53 alteration in gastric precancerous lesions.

open access: yesThe American journal of pathology, 1994
It has been postulated that chronic atrophic gastritis, intestinal metaplasia, and dysplasia are precancerous stages of stomach tumorigenesis. We investigated the timing of p53 alterations in these events of gastric tumorigenesis. Each of 12 cases of archived tissue containing precancerous and cancerous lesions were selected for the detection of p53 ...

Bacterial Involvement in Oral Squamous Cell Carcinoma and Potentially Malignant Oral Disorders

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective To clarify the relationship between oral squamous cell carcinoma (OSCC), potentially malignant oral disease (OPMD), and bacterial flora using metagenomic analysis. Methods This cross‐sectional observational study included 50 patients in the control group and 77 patients with OPMDs, 41 with early OSCCs, and 20 with advanced OSCCs ...

Helicobacter pylori infection and gastric cancer [PDF]

open access: yes, 1999
Gastric cancer is the second most common fatal malignant neoplasm in the world. In mainland China, gastric cancer is now the second most common malignant neoplasm while in Hong Kong, the mortality rate ranked fourth of all cancers in 1995.

Molecular mechanisms of helicobacter pylori pathogenesis [PDF]

open access: yes, 2015
Helicobacter pylori infects 50% of mankind. The vast majority of H. pylori infection occurs in the developing countries where up to 80% of the middle-aged adults may be infected. Bacterial infection causes an inflammatory response that proceeds through a

Immune, molecular and genetic profiles of gastric signet ring cell carcinoma: Recent progress and future challenges

open access: yesInternational Journal of Cancer, Volume 159, Issue 1, Page 11-29, 1 July 2026.
Abstract Gastric signet ring cell carcinoma (GSRCC) is a special type of gastric cancer common in young women. Diffuse gastric cancer (DGC) begins with intramucosal lesions comprising differentiated GSRCC cells. Genetically, GSRCC and DGC are clonally identical, with their morphology influenced by extracellular Wnt signaling.
