[THE MORPHOMETRY IN CYTOLOGICAL ANALYSIS OF EXUDATIVE FLUIDS]

The cytological technique takes a leading position in diagnostic of tumor processes according exudative fluids. However, its results depend on large number of subjective factors. The morphometry is one of techniques by virtue of which objectification of data of cytological analysis is possible. The study was carried out to establish differences of morphometric parameters of benign and malignant cells of pleural effusion. The morphometric analysis of cells of mesothelium, breast cancer, adenocarcinoma of lung and adenocarcinoma of stomach was implemented. The parameters characterizing size (area, perimeter) and form (form factor) of nucleus and cell, nucleus-cytoplasm ratio. The results demonstrated that in pleural effusion between cells of proliferating mesothelium and malignant neoplasms exist significant differences in morphometric parameters (p<0.001). The differences between area of nuclei and cells are especially significant. The comparison of data of morphometry of cells of breast cancer; adenocarcinoma of lung and adenocarcinoma of stomach demonstrated that despite of some morphological similarities, analysis of morphometric parameters can provide important data for proper establishment of cytological diagnosis.
