Brain Metastases from Gynecologic Malignancies

Background and Objectives: To present a series of brain metastases from gynecologic primaries and provide a summary of the relevant literature. Materials and Methods: We retrospectively review 18 patients with histologically confirmed brain metastases from gynecologic primaries and summarize the largest series of relative reports. Results: Six brain metastases were of endometrial primary and 12 of ovarian primary. In 3 cases (16.7%), diagnosis of brain metastases was made at presentation of the gynecologic primary; in the others, median time to development of brain metastasis was 34 (range, 6-115) months. Median survival after brain metastasis diagnosis was 5 (range, 1-89) months. Favorable prognostic factors were better performance status (p = 0.04) and, marginally, smaller metastasis size (p = 0.06). No differences in brain metastases between endometrial and ovarian primaries were found, except for the time interval from primary to brain metastases diagnosis, which was shorter for endometrial tumors (p = 0.05). A comprehensive summary of previous studies is provided. Conclusions: Performance status and smaller brain metastases size are good prognostic factors. Endometrial cancer brain metastases develop earlier than ovarian cancer brain metastases.

Automated summary

This study retrospectively reviewed 18 cases of brain metastases from gynecologic primaries and summarized the relevant literature. The results showed that better performance status and smaller metastasis size were favorable prognostic factors. Brain metastases from endometrial cancer develop earlier than those from ovarian cancer.
