title: [Morphologic diagnosis of the initial stages of stomach cancer (an analysis of 252 cases)].
abstract: Cancer involvement of the stomach diagnosed in 225 patients appeared limited to tela submucosa in 252 cases and mucosa in 64.5% of cases. Early diagnosis of metachromatic postoperative cancer was established in 7.6% of patients. Macroscopic forms of the tumors varied. Adenocarcinoma prevailed histologically, its well-differentiated forms occurring in superficial twice as often as in invasive cancer. In 71.8% of patients tumor growth was accompanied by epithelial dysplasia varying in degree. Severe dysplasia was more common in superficial cancer. Carcinomas of exclusively mucosal localization are usually small-sized, differentiated, more distinctly associated with precancer conditions.
