This study aimed to investigate the response of platinum-sensitive advanced ovarian cancer patients to PARP inhibitor treatment. The results showed that receiving pegylated liposomal doxorubicin-oxaliplatin treatment improved progression-free survival and overall survival in platinum-sensitive advanced ovarian cancer patients. In BRCA-mutated patients, pegylated liposomal doxorubicin-oxaliplatin treatment improved progression-free survival.
Background:The use of PARP inhibitor (PARPi) has shown a considerable benefit in progression-free survival (PFS) in relapsed, platinum-sensitive epithelial ovarian cancer (OC). Objective:Our study aimed to investigate the impact of the last platinum-based chemotherapy treatment in response to PARPi. Design:Retrospective cohort study. Patients and methods:The study involved 96 consecutive, pretreated, platinum-sensitive advanced OC patients. Demographics and clinical data were retrieved from clinical records. PFS and overall survival (OS) were calculated from the start of PARPi. Results:Germline BRCA mutation was investigated in all cases. Platinum-based chemotherapy before PARPi maintenance therapy included pegylated liposomal doxorubicin-oxaliplatin (PLD-Ox) in 46 patients (48%) and other platinum-based chemotherapy in 50 patients (52%). During a median follow-up of 22 months from the beginning of PARPi therapy, 57 patients relapsed (median PFS: 12 months) and 64 patients died (median OS: 23 months). During multivariable analysis, receiving PLD-Ox before PARPi was associated with improved PFS [hazard ratio (HR): 0.46, 95% CI: 0.26-0.82] and OS (HR: 0.48, 95% CI: 0.27-0.83). In 36 BRCA-mutated patients, PLD-Ox was associated with improved PFS (2-year PFS: 70.0% versus 25.0%, p = 0.02). Conclusion:Receiving PLD-Ox before PARPi may improve prognosis in platinum-sensitive advanced OC patients and may provide advantages in the BRCA-mutated subgroup.
