Objectives:
Helicobacter pylori infection induces gastritis, which may evolve to carcinoma or lymphoma. Whether duration of infection and inflammation pattern determine the outcome of the neoplastic process is not known. The aim of this study was to investigate the features of the gastritis associated with neoplasia.
Methods:
Gastritis found in association with carcinoma (100 cases) and lymphoma (45 cases) were graded using the Sydney system.
Results:
In particular in the antrum, gastric carcinomas, in particular of the intestinal type, were associated with a chronic (94%, n = 34/36) atrophic (92%, n = 33/36) gastritis and intestinal metaplasia (81%, n = 29/36). In diffuse type carcinomas inflammation was either absent or mild. An active (64%, n = 16/25), chronic gastritis (100%, n = 25/25) with lymphoid hyperplasia (72%, n = 18/25) was found in marginal zone cell lymphoma.
Conclusions:
Our study shows that the (pre)atrophic phases of inflammation are associated with gastric carcinomas. In contrast the active phase of inflammation, characterized by severe activity as well as severe chronicity, is found next to marginal zone cell lymphoma.

Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
Gastritis II: Pathophysiology
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Peptic Ulcer
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
Peptic ulcers can also be...
