BACKGROUND/AIM: Mutations of BRCA1/2 improve cancer prognosis due to their better response to platinum-based chemotherapy. This study evaluated overall survival (OS) and progression-free survival (PFS) under similar conditions of first-line adjuvant chemotherapy within seven years in high-grade serous ovarian cancer (HGSOC).
PATIENTS AND METHODS: A total of 160 patients were enrolled. The pathogenic BRCA1/2 variant group included pathogenic variant and likely-pathogenic variant, while the non-pathogenic group included wild-type and variant of uncertain significance. For first-line chemotherapy, delivered dose intensity, relative dose intensity, and delay of duration were calculated in all patients.
RESULTS: Of the tested variants, 108 (67.5%) were non-pathogenic and 52 (32.5%) were pathogenic. No significant difference was found in various clinical factors of cancer stage, surgery, or chemotherapy. There was no significance for OS or PFS within five or seven years.
CONCLUSION: In patients with HGSOC, the OS and PFS for germline BRCA1/2 pathogenic and non-pathogenic variants were not significantly different under similar conditions of first-line adjuvant chemotherapy within seven years.
