[Cytologic method for determination of histological structure in precancer and cancer of the cervix uteri].

The authors studied comparatively cytologic and histological findings in 164 patients in whom pretumor lesions (82) and cervical cancer (82) were revealed. The precision of cytologic diagnosis of pretumor lesions was 95.1 +/- 4.8%, of cancer--91.4 +/- 6.2%. Of 95 observations in which epithelial atypia, from proliferation to cancer, was detected the degree of cell atypia was correctly determined cytologically in 82.1 +/- 8.1% of observations, the degree of differentiation--in 85.2 +/- 7.2%, both factors--in 68.4 +/- 9.5%. Of 67 observations, in which cervical cancer was correctly diagnosed cytologically, the precision of prognosticating the presence of preinvasive and invasive cancer was 86.5 +/- 8.4%, while the degree of differentiation was diagnosed correctly in 83.5 +/- 9.0%, the histostructure being determined precisely in 71.6 +/- 11%.
