Is It Possible to Prevent Nontherapeutic Laparotomies in Breast Cancer Patients With Isolated Adnexal Masses?

The risk of ovarian malignancy is increasing in patients with a history of breast cancer. Thus, well-defined predictors of ovarian malignancy should be identified to determine surgical or conservative management of adnexal masses in women with breast cancer. This study aimed to clarify the predictors of malignant ovarian tumors in patients with breast cancer with an isolated adnexal mass. Breast cancer patients diagnosed with an adnexal mass who underwent surgery between 2010 and 2021 at a tertiary cancer center were included in the study. Patients with suspected extra ovarian metastases were excluded. A total of 40 breast cancer patients who underwent surgery for ovarian masses were identified. 23 (57.5%) women had benign ovarian tumors and 17 (42.5%) had malignant ovarian tumors. Among the malignant ovarian tumors, there were three (17.6%) metastatic breast cancers in the ovary and 14 (82.4%) primary ovarian cancers. In univariate analyses, the risk of malignant ovarian tumors increased in women with age >52 years ( = .012), postmenopausal status ( = .023), CA 125 ≥ 35 IU/ml ( = .001), CA 15-3 ≥ 32 IU/ml ( = .002), and complex ovarian masses ( < .001). Ovarian malignancies were observed in 82.4% of patients who had complex ovarian masses. Ovarian malignancies were diagnosed in 82.4% of the breast cancers who had complex ovarian mass on USG examination. Therefore, surgery is recommended in women with complex ovarian masses. Postmenopausal status, age >52 years, CA 125 ≥ 35 IU/ml, and CA 15-3 ≥ 32 were other risk factors for ovarian malignancy.
