Abstract
There were performed researches on morphometric (the nuclear area, perimeter, the maximum and minimum diameters) and densitometric (optical density, integrated optical density) parameters of nuclei of cells on the cytologic smears received from 28 patients with atypical hyperplasia and an initial breast cancer. Significant reduction of measured nuclei parameters was noted among: moderately - and high-grade ductal carcinoma in situ, atypical ductal hyperplasia, lobular carcinoma in situ, an invasive papillary cancer, intraductal papilloma. The lowest value of the measured parameters was noted at love-grade ductal carcinoma in situ and intraductal papillary cancer. It was established that morphometric and densitometric indicators at atypical hyperplasia of an epithelium and an initial breast cancer in some cases overlap each other that is at the bottom of difficulties of differential cytomorphological diagnostics and quite often forces to formulate the cytologic conclusion in the presumable form.References
