Endometrial carcinoma diagnosed by the Gynoscann method.

A simple method for screening of the endometrium is a desirable complement to the gynecological examination. Between February and June, 1984, 94 patients underwent cytological sampling by the Gynoscann method immediately before dilatation and curettage at the Department of Gynecological Oncology, Radiumhemmet, and at the Department of Obstetrics and Gynecology, Karolinska Hospital, Stockholm. Ninety-six per cent of the cytological samples were adequate for cytological diagnosis and the same proportion of the curettage specimens for histology. The correlation between cytology and histology was correct in 84% of the cases. Among the 26 cases of endometrial carcinoma, 21 (80%) were correctly diagnosed by cytology. There were no false-positive diagnoses for carcinoma. Atypical hyperplastic endometrium was found in 2 cases by curettage and was correctly correlated with cytology in one case. The sensitivity for endometrial carcinoma was 81% and the specificity 100%. Our conclusion is that the Gynoscann method is safe, easy to use and has proved reliable for the diagnosis of endometrial carcinoma. Further evaluation with larger series giving the cytopathologists increased experience is needed before optimal sensitivity can be achieved.
