Accuracy of three sampling technics for the diagnosis of endometrial cancer and hyperplasias.
Intrauterine aspiration (Vakutage), endocervical aspiration cytology and vaginal, ectocervical and endocervical (VCE) smears were used as outpatient procedures for diagnosis of endometrial cancer and hyperplasias in 840 patients. The results of the three technics were correlated with D&C or hysterectomy specimens. Ninety-three percent of the malignant lesions (82 adenocarcinomas, 5 mixed mesodermal tumors, 5 mixed adenosquamous carcinomas and 5 metastatic adenocarcinomas) were diagnosed by the Vakutage sample but only 67% by the VCE smears and 68% by endocervical aspiration cytology. The diagnostic accuracy of Vakutage in 50 cases of cystic hyperplasia was 88% (as compared to 14% for VCE smears and endocervical aspiration cytology) and 89% in 90 cases of adenomatous hyperplasias (as compared to 20% for the other two technics). Endometrial polyps were diagnosed exclusively from the Vakutage tissue sample in 83% of the 42 cases.
