[Results of prospective cytological diagnoses of cervical intraepithelial neoplasia].

The value of prospective cytologic diagnosis in cervical intraepithelial neoplasia (CIN) is analysed by means of ROC (receiver operating characteristic) curves. Examined was a group of 160 women with subsequent cone biopsies. The result of a prospective cytologic diagnosis in moderate dysplasia, severe dysplasia and carcinoma in situ is analysed separately, taking into consideration the particular frequencies in the studied group. The most reliable prospective cytologic diagnosis is in moderate dysplasia, followed by carcinoma in situ a slightly more reliable prospective diagnosis than that in severe dysplasia.
