[Quantitative research methods in the differential diagnosis of dysplastic processes and tumors of various types of...

Complex morphological and morphometrical study of 71 connective tissue, 95 smooth muscle and 90 epithelial tumours is performed; high efficiency of quantitative methods in differential diagnosis of dysplasia and tumours is demonstrated. Quantitative criteria reflect objectively the qualitative changes taking place in the process of malignization in the parenchyma and stroma. Histogenetic verification of a tumour must precede the use of quantitative methods. A wide introduction into practice of a multifactorial quantitative analysis is possible on the basis of the automatized numerical analysis of images.
