[Clinical analysis of ovarian metastasis in patients with Ⅰb stage cervical adenocarcinoma]

To investigate the rate of ovarian metastasis and its related factors in patients with cervical adenocarcinoma, and explore whether the ovary should be reserved or not in cervical adenocarcinoma.

The clinical data of 111 patients with cervical adenocarcinoma who received extensive total hysterectomy plus pelvic lymph node resection in Sun Yat-sen Memorial Hospital and Quanzhou Women's and Children's Hospital from January 2008 to December 2014 were collected and analyzed by single factor χ(2) test and multivariate logistic regression analysis.

The median age of the included 111 cases of cervical adenocarcinoma was 44. Sixty-five of the patients were stage Ⅰb1, while 46 were stage Ⅰb2. The single factor analysis indicated that lymph-vascular space invasion(LSVI), lymph node status, interstitial infiltration depth, parametrial involvement and involvement of cervical body junction were associated with ovarian metastasis. Multivariate analysis indicated that LSVI (HR: 47.01, 95% CI: 2.48-890.03, P=0.010) and lymph node status (HR: 23.58, 95% CI: 1.20-463.21, P=0.038) were independent risk factors for ovarian metastasis.

Ovarian metastasis rate of stage Ⅰb cervical adenocarcinoma is low; patients with age less than or equal to 45 years old, negative LSVI, <1/2 cervical stromal invasion, no lymph node metastasis and no cervical body junction involvement can consider preservation of ovary; but these findings still need to be further confirmed by large randomized controlled trials.
