About Endometrial Cytology With Tissue Correlations

As compared with cytology’s use in other organ systems, direct cytological examination of the endometrium is not a widely practiced diagnostic procedure. This is an anomaly, because the endometrium is exceedingly available for cytological sampling, cytological sampling is comparably simple to perform, and, from the patient’s perspective, it is a gentle procedure as compared to other methods of specimen attainment. Over the years, as we personally gained more and more experience with specimen acquisition, processing and interpretation, we have come to look upon endometrial cytology as an effective method for ensuring endometrial normalcy and discovering and diagnosing malignant and premalignant states. In comparing endometrial cytology to endometrial biopsy, we have found that, in samples obtained by individuals experienced in specimen collection, cytology outperforms outpatient biopsy with regard to the patient’s tolerance of the procedure, adequacy of sampling among postmenopausal women, and detection of occult neoplasms. By devising a highly effective technical strategy to ensure the simultaneous creation of cell blocks and cytological samples from a single collection (that is detailed in the technical appendix of this work), we have moved endometrial brush collection into an arena of significance equaling—indeed exceeding—other methods of specimen collection and interpretation. Cytology, even in the absence of cell blocks, performs equally as well as biopsy in detecting outspoken hyperplasia or carcinoma. If nothing else, by reliably identifying benign, normal endometrial states, it serves to exclude more than 70% of women from unnecessary follow up testing with a high degree of confidence. Because brush sampling of the endometrium is limited to a depth of 1.5 to 2 mm, the method is not definitive for the detection of endometrial polyps, fibroids, stromal tumors, or tumors of the uterine wall musculature. However, endometrial cytology is useful for detecting beni
