title: [Comparative assessment of the informative value of parallel cytological and histological studies of gastric biopsy specimens in the diagnosis of various diseases of the stomach].
abstract: To analyze the diagnostic efficiency of parallel cytological and histological studies of gastric biopsy specimens, the author examined a group of 512 patients with various diseases of the stomach. The diagnosis of nonneoplastic disease was endoscopically established in 7 (10.5%) patients with the morphologically verified diagnosis of gastric cancer, i.e. its misdiagnosis was made. A cytological study proved to be more effective in diagnosing gastric cancer than a histological one (98.5% versus 97%). The way of enhancing the efficiency of cytology is to qualitatively prepare impression smears from the whole biopsy material.
