Abstract

Background: Brain metastasis (BM) are uncommon among women with epithelial ovarian cancer (EOC). The frequency, risk factors and clinical repercussions of BM in these patients are not well described. Methods: We retrospectively evaluated EOC patients treated at our center from 2002 to 2020 and assessed their clinical parameters, risk for BM development and association with overall survival (OS). This cohort has a known high frequency of BRCA mutation carriers (BRCAm) due to women of Ashkenazi Jewish descent. Results: Among 1035 EOC patients, 29 (2.8%) were diagnosed with BM. The prevalence of BRCA mutations was more common among women with BM (56.5% vs. 34.3%, p = 0.033). The BM rate in patients with BRCAm was higher than the BM rate in those with wildtype BRCA (BRCAw; 5.1% vs. 2.1%, OR = 2.6; 95% CI: 1.2–5.4, p = 0.013). Median time from diagnosis to BM and from disease recurrence to BM was longer among patients with BRCAm. Median OS was not significantly different among patients with BM versus those without BM (59.4 vs. 73.4 months, p = 0.243). After BM diagnosis, median OS was not statistically significantly different between patients with BRCAm and those with BRCAw (20.6 vs. 12.3 months, p = 0.441). Treatment with poly (ADP-ribose) polymerase inhibitors and bevacizumab had no impact on subsequent development of BM. Conclusions: BM are rare among EOC patients. However, the risk is three-fold higher among patients with BRCAm. BM do not significantly alter OS among EOC patients. The higher rate of BM in patients with BRCAm may be related to longer OS in this subpopulation.
