[Cytometry and the degree of differentiation of squamous-cell lung cancer]

Cytometric studies of samples from 65 patients (20 with well-differentiated carcinoma, 32 with moderately differentiated and 13 with poorly differentiated tumors), carried out with the Integral-2MT cytoanalyzer, have shown an inverse relationship between the size of the nuclei, nuclear-cytoplasmatic ratio, and the degree of pulmonary carcinoma differentiation. The results of the study will promote a more objective assessment of carcinoma cells and will improve the efficacy of cytologic diagnosis of squamous cell carcinoma of various differentiation degrees.
