Abstract

Background/Aim: This study aimed to determine the effect of different BRCA1 exonal mutations on the clinical course of epithelial ovarian cancer (EOC). Patients and Methods: Clinicopathological variables and survival outcomes were compared among 53 primary EOC patients with pathogenic BRCA1 mutations in exons 1-11 (5’ mutations) and in exons 12-24 (3’ mutations). Results: BRCA1 5’ exonal mutations were found in 35 (66.0%) patients. The median follow-up period was 40 months. Clinicopathological variables remained unchanged between the two groups. Patients with 5’mutations had a significantly longer progression-free survival than those with C-terminal mutations (p=0.034), better predicting progression-free survival [2.923 (1.402-6.093), p=0.004], but not overall survival in cases of multiple relapses (p=0.497). Conclusion: N-terminal BRCA1 mutations in EOC patients are associated with favourable primary progression-free survival, a trend observed only in primary progression-free survival, not in overall survival.
