Criteria for the cytologic assessment of hyperplasias in endometrial samples obtained by the Endopap Endometrial Sampler.
The Endopap Endometrial Sampler was used in 1,465 women, either just before endometrial biopsy or curettage (in 760 symptomatic patients) or as an office procedure (in 705 women). The samples were inadequate for interpretation in only 8.7% of the cases. Although all malignant lesions were identified by this screening technique, about one-fourth were initially classified cytologically as hyperplasia. Endometrial hyperplasias presented the greatest difficulties in interpretation, with only slightly over half of the proven cases correctly assessed on the endometrial sample. In an attempt to improve the accuracy of the cytologic diagnosis of hyperplasias, ten morphologic features were examined retrospectively in 207 cases. Five of the criteria were shown to provide an increased probability of correctly diagnosing endometrial hyperplasias on the cytologic sample: (1) the overlapping of cells in the glandular clusters or sheets, (2) the presence of nucleoli, (3) anisokaryosis, (4) granularity of chromatin and (5) the presence of sheets of stromal cells. The more of these criteria observed in a given case, the better was the chance of cytologically identifying a hyperplasia in the Endopap sample.
