Definitions of Platinum-Refractory, Platinum-Resistant, Potentially Platinum-Sensitive, and Fully Platinum-Sensitive Ovarian Cancer. Patients with ovarian cancer are classified broadly in two main categories: “platinum-resistant” if the platinum-free interval (PFI) is less than 6 months, and “platinum-sensitive” if the PFI is at least 6 months. A more specific classification defines patients with ovarian cancer as “platinum-refractory” if disease progression occurs during chemotherapy or within 4 weeks after the last dose, “platinum-resistant” if the PFI is greater than 1 month and less than 6 months since last line of platinum-based therapy, “potentially platinum-sensitive” if the PFI is between 6 and 12 months, and “platinum-sensitive” if the PFI is more than 12 months
