title: [Application of automated quantitative cytometry in diagnosis of lung cancer].
abstract: The paper deals with evaluation of the literature data and our experience with automated quantitative cytometric examination of sputum for diagnosis of lung cancer and, in particular, early one. This novel procedure uses measurement of quantitative indices which characterise tumors-induced alterations. The LungSign computerized system was employed to scan cellular nuclei. The results were evaluated by linear discriminative analysis with the aid of ROC-curves and underlying areas. The procedures were run in 248 cases and its sensitivity was significantly higher that of a standard cytological one (36.6% and 13.3%, respectively; p = 0.033), albeit a slight decrease in specificity (93.7% and 100%, respectively; p = 0.003). Automated quantitative cytometric indices varied significantly in cohorts of patients with confirmed (-0.275871) and false (-1.24990) diagnosis of lung cancer (p = 0.0001).
