Immunocytochemical method for diagnosis of metastases of signet ring cell carcinoma of the stomach

Abstract

Associated factors were analyzed by the chi-square and multiple logistic regression with SPSS 20.0 and dispersion analysis (ANOVA). Results: The overall prevalence of H. pylori infection in patients with dyspepsia was 87.6% (2189 patients) and 81% (81 patients) in control patient group with no symptoms. In a group of 126 patients (median age 64,569.8; 78 (61.9%) males and 49 (38.9%) females with newly diagnosed adenocarcinoma, in 58 (46%) the tumor was located in antrum, in 33 (26.2%) at the lesser curvature, in 13 (10.3%) at the greater curvature, in 17 (13.5%) at the cardial part and in 5 (4%) patients in the fundus. H. pylori test was positive in 52 (89.6%) of 58 patients with antral malignancy, in 29 (87.9%) of 33 patients with lesser curvature cancer, in 7 (53.8%) of 13 patients with greater curvature cancer, in 5 (29.4) of 17 patients with cardial malignancy and in 2 (40%) of 5 patients with fundus and body malignancy. Conclusion: The prevalence of H.Pylori in patients with dyspeptic symptoms is 87.6% comparing to 81% of general population. Besides age and gender predisposion, H.Pylori infection is strongly associated with the development of antral and lesser curvature adenocarcinoma comparing to cardia, fundus and greater curvature malignancy locations.
