Abstract
The Isaacs cell sampler was tested in 150 women (102 of them postmenopausal) referred for curettage. The results of cytological testing of material obtained with the sampler were compared with histological findings from curettage performed immediately afterwards. Satisfactory aspirates for cytological diagnoses were obtained in 141 patients and satisfactory material for histological diagnosis in 124. In the 102 postmenopausal patients the cytological method yielded 94 satisfactory specimens, while curettage yielded only 76. All the 17 carcinomas were diagnosed cytologically. Of the 12 cases of premalignant change, nine were diagnosed cytologically; two cytologically diagnosed premalignant cases did not, however, yield satisfactory material by curettage. The Isaacs cell sampler is a simple and reliable way of diagnosing malignancies. Further investigation is needed to define the cytological criteria for diagnosing premalignant cases, but as the material is well preserved accuracy should improve with increasing experience. The method should be valuable in screening women having oestrogen substitution therapy.
