Preoperative cervical cytology in endometrial carcinoma and its clinicopathologic relevance.
OBJECTIVE
The aim of this study was to assess the significance of malignant or suspicious cervical cytology in preoperative identification of poor prognostic factors in endometrial carcinoma and to determine whether preoperative abnormal cervical cytology is an independent prognostic factor for endometrial carcinoma.


METHODS
We evaluated the correlation between preoperative cervical cytology and postoperative clinicopathologic findings, sites of metastasis, and receptor status from 99 surgically staged patients with endometrial carcinoma.


RESULTS
Sixty-eight patients (68.7%) had normal cervical cytology, 1 (1.0%) had atypical cytology suspicious for malignancy, and 30 (30.3%) had malignant cytology on preoperative cervical cytology. Malignant and suspicious cervical smears were statistically correlated with surgical stage (P = 0.001), histopathology (P = 0.010), tumor grade (P = 0.012), depth of myometrial tumor invasion (P = 0.001), cervical involvement (P = 0. 01), lymph node metastases (P = 0.002), adnexal metastases (P = 0. 012), progesterone receptor (P = 0.007), and estrogen receptor (P = 0.031). No association was found between preoperative cervical cytology and patients' age or peritoneal cytology. Univariate analysis showed that cervical cytology was related to survival (P = 0.018). However, multivariate analysis of cervical cytology, stage, grade, and myometrial invasion showed that preoperative cervical cytology was not a significant prognosticator for survival.


CONCLUSIONS
Patients with endometrial carcinoma who have malignant or suspicious cytology detected by preoperative cervical cytology are at increased risk of having known poor prognostic factors. However, positive preoperative cervical cytology itself does not appear to be an independent prognostic factor and probably should not influence treatment decisions in endometrial cancer.
