title: [Cytological classifications of precancerous conditions and cancer of the lung, breast, esophagus and stomach].
abstract: Cytological classifications of cancer and precancerous lesions of the lung, breast, esophagus and stomach are suggested. They are based on the analysis of the results of research and practical experience gained at the Institute in the treatment of more than 2,000 cases. The cytological classifications are in conformity with those of WHO and provide for identification of malignancy, histological pattern, degree of tumor differentiation as well as the degree of dysplasia in precancerous lesions.
