PARP Inhibitors Rising as an Epoch-Making Strategy in First-Line Maintenance Therapy of Ovarian Cancer: A Systematic Review and Meta-Analysis

To illustrate the accurate location of Poly-ADP-ribose polymerase inhibitor (PARPi) as the first-line maintenance therapy in advanced ovarian cancer (AOC).
Search for eligible studies and calculate clinical outcomes.
PARPi as a first-line maintenance treatment significantly prolonged the BRCAmut population and the homologous recombination deficiency (HRD) positive population.
PARPi as first-line maintenance therapy significantly improves the progression-free survival in AOC, especially in the BRCAmut and HRD positive populations. PARPi has been becoming the standard first-line maintenance therapy for AOC.
