Cervical cancer is a common malignant tumor in women; most cervical cancer patients are premenopausal. Ovarian resection or preservation remains controversial. The purpose of this study was to discover the risk factors for ovarian metastasis in women with stage I‐II cervical cancer. Material and methods A total of 3292 women with cervical carcinoma who had undergone radical hysterectomy, with pelvic lymphadenectomy and bilateral oophorectomy or wedge resection of ovaries, were included in this multicenter retrospective study. We analyzed patients’ demographics, International Federation of Obstetrics and Gynecology stage, and histopathologic records to determine clinicopathologic risk factors of ovarian metastasis. Results Of the patients, 115 (3.49%) were confirmed to have ovarian metastasis. The ovarian metastasis rate was 2% (56/2794) for squamous cell carcinoma and 11.8% (59/498) for nonsquamous cell carcinoma. The risk factors independently associated with ovarian metastasis were histologic type (odds ratio [OR] 8.76, 95% CI 2.09‐19.24), lymph node metastasis (OR 2.57, 95% CI 1.76‐4.89), lymphovascular space invasion (OR 2.82, 95% CI 1.98‐4.24), and corpus invasion (OR 6.34, 95% CI 2.37‐11.42). Conclusions The histologic type, lymph node metastasis, lymphovascular space invasion, and corpus invasion were independently associated with ovarian metastasis. Histologic type and corpus invasion were the most important risk factors. Therefore, we suggest that corpus invasion might be a strong contraindication for preservation of the ovaries.
