    Abstract

    There is a need for additional morphologic criteria to improve the value of histologic classification for the prediction of the biologic behavior of cervical intraepithelial neoplasia (CIN). Representative slides from 72 cone specimens containing CIN were examined to study the correlation between the presence of three group metaphases (TGMs), a morphologically well defined and light microscopically readily recognizable atypical mitotic figure, and the incidence of aneuploid cells with a nuclear DNA content >5C. The numbers of cells >5C (minus the polyploid cells 8C+/-1C) were counted, using LEYTAS image cytometry on Cytospin preparations from the 72 blocks corresponding to the slides searched for TGMs and used for histologic classification of the lesions in classes CIN 1-3. It appeared that large numbers of aneuploid cells >5C were more closely related to the presence of TGM than to a higher CIN class per se, particularly in women older than 35. Since aneuploid CIN has a higher progression rate than euploid CIN, the presence of TGMs will indicate a biologically unfavorable lesion. Thus, TGM deserves further investigation as an additional morphologic parameter for predicting the biologic behavior of CIN.
