[Occurrence of Helicobacter pylori in patients with gastroesophageal tumors].

Authors examined the occurrence of H. p. retrospectively in bioptic material for three years. Fifty-one oesophageal and gastric tumorous patients were examined and as a control fourty-seven non tumorous patients with chronic gastritis chosen at random. The demonstration of H. p. was performed by modified Giemsa stain. Different types of chronic gastritis, forms and localisation of the tumours as well as their relation with sex and age were investigated. The occurrence of H. p. was higher in chronic gastritis than in tumorous processes. Seventy-one % H. p. positivity was found in the control group against 17.6% in the tumorous patients.
