ABSTRACT
OBJECTIVE:
To understand the relationship between primary platinum-free interval (PFI), BRCA mutation status, and overall survival (OS) in patients with recurrent ovarian cancer receiving multiple lines of therapy in a multicenter, community-based, retrospective observational cohort study of adult patients with stage III-IV high-grade ovarian cancer.METHODS:
Data were retrospectively obtained from the electronic health record (EHR) of a US community oncology network, including patient characteristics, subsequent treatments, primary PFI, and BRCA status. OS was analyzed by the Kaplan-Meier method, stratified by primary PFI and BRCA status.RESULTS:
750 patient charts were reviewed. BRCA testing status was known in 267 patients (16% BRCA mutation). Among patients with identified recurrent disease, 41% had a primary PFI <6months and 59% had a primary PFI ≥6months. Of second-line patients, 59% received third-line therapy, and 60% of third-line patients received fourth-line therapy within the period of observation. Median OS from the start of primary treatment for the entire population was 41.4months (95% CI, 39.0-48.3months). Median OS was significantly increased in patients with primary PFI ≥6months at second-line and third-line (P<0.0001 and P=0.002, respectively). Survival was observed to be increased among patients with BRCA mutations across multiple treatment lines, although this was not statistically significant.CONCLUSIONS:
Patients with a primary PFI ≥6months demonstrated improved outcomes over multiple lines of therapy. BRCA status was known in 36% of patients, and those patients with a BRCA mutation demonstrated a trend toward delayed primary recurrence and improved clinical outcomes.Mots clés
