Objective To report on the uptake of breast cancer screening strategies in epithelial ovarian cancer patients with BRCA1 or BRCA2 mutation.

Methods A retrospective review of the clinico-pathologic data and implementation of breast cancer surveillance was performed on patients who were diagnosed with epithelial ovarian cancer at a single center between 2009 and 2019. If annual mammography or breast MRI was performed, it was considered that breast cancer screening was done following the guidelines.

Results A total of 309 women were diagnosed as epithelial ovarian cancer during the study period. Of these, 66 patients (21.4%) carried out BRCA testing. Thirteen patients (19.7%) had BRCA1/2 pathogenic/likely pathogenic variants, 10 of whom with BRCA1 mutation and 3 with BRCA2 mutation. Among the 13 patients with BRCA1/2 mutation, 10 patients received annual mammography with or without breast ultrasonography. Only 1 patient performed breast MRI. During the follow-up period, 1 patient developed breast cancer and another patient was diagnosed with pancreatic cancer.

Discussion The uptake of BRCA1/2 testing and breast cancer surveillance among epithelial ovarian cancer patients with BRCA1/2 mutation is still not optimal, and strategies to increase uptake are needed.
