Abstract

The aim of the study was to ascertain presence of Helicobacter pylori in gastric carcinoma as a responsible promoter of inflammatory-regenerative changes, which lead to pathological differentiation and transformation of normal epithelial cells into intestinal type and, in progression, cause epithelial dysplasia that develops into early gastric carcinoma. The paper presents prospective study that includes clinical, pathohistological and microbiological aspects of carcinogenesis initiation in gastric mucosa. The subjects are patients treated at Gastroenterohepatology Clinic divided into two groups. One group included 50 patients with gastric carcinoma while the control group included 50 patients with chronic atrophic H. pylori positive gastritis. All the patients were subjected to endoscopy as well as biopsy targeted at antrum, lesser curvature and corpus and at the region 1-2 cm removed from tumor lesion. We used HUT test to verify H. pylori presence in biopsy samples. We analyzed the samples for presence, frequency and severity of inflammatory-regenerative, metaplastic and dysplastic changes in gastric mucosa and evaluated their meaning for the prognosis. Our study confirmed Helicobaster pylori responsibility for inflammatory events in gastric mucosa in patients with gastric carcinoma. Slight and mild epithelial dysplasia with chronic atrophic gastritis grade I and II coupled with intestinal metaplasia may be considered an indicator for early detection of carcinoma. Such patients represent risk group for gastric carcinoma development.
