title: ThinPrep Pap tests in patients with endometrial cancer: a histo-cytological correlation.
abstract: The aim of this retrospective study was to correlate cytological diagnoses of endometrial cancers in ThinPrep Pap tests with the histological diagnoses. ThinPrep specimens from 67 patients within 12 mo of the histological diagnosis of endometrial cancer were studied. Of this study sample, 89.6% had abnormal Pap tests. Abnormal Pap tests occurred in 96.8, 68.4, and 100% of patients with grades 1, 2, or 3 endometrial cancers, respectively. Of patients with endocervical involvement, 88.9% had positive or suspicious Pap tests, compared with 41.1% without endocervical involvement (LR = 7.85, P < 0.01). Of patients with > or =50% myometrial invasion, 78.9% had positive or suspicious Pap tests, compared with 34.8% with less than 50% invasion (LR = 10.97, P < 0.01). Positive or suspicious Pap tests were found in 59.5 and 32.1% of those with tumors > or =3 cm or <3cm, respectively (LR = 4.85, P < 0.05).
