Resumen:
Objective. Progression-free survival (PFS) is an important early efficacy endpoint in ovarian cancer (OC) and its relevance to patients should be assessed. PRIMA, a phase III trial, assessed niraparib in patients with OC; this post hoc analysis examined the relationship between disease progression in OC and health-related quality of life (HRQoL).Methods. The PRIMA trial randomized patients with advanced OC responsive to first-line platinum-based chemotherapy to once daily maintenance oral niraparib or placebo. This post hoc analysis evaluated the impact of dis-ease progression on HRQoL by comparing HRQoL at the last visit pre-progression to end of treatment (EoT), and after 4, 8, 12, and 24 weeks. Assessments included the Functional Assessment of Cancer Therapy-Ovarian Symptom Index (FOSI), the European Quality of Life Five Dimension Five Level questionnaire (EQ-5D-5L) and EQ Visual Analogue Scale (EQ-VAS), the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Question-naire (EORTC-QLQ-C30), and the EORTC Quality of Life Questionnaire Ovarian Cancer module (EORTC-QLQ-OV28).Results. This post hoc analysis included 733 patients. Mean FOSI, EQ-5D-5L, and EQ-VAS scores deteriorated from last visit pre-progression to EoT and remained low up to 24-week follow-up. Least squares mean changes from last visit pre-progression to EoT were -2.1 (95% confidence interval -2.4, -1.7) for FOSI, -4.6 (-5.6, -3.5) for the EQ-5D-5L index, and -7.9 (-9.6, -6.3) for EQ-VAS.Conclusions. Disease progression negatively impacted HRQoL in patients with OC. PFS is clinically relevant, and prolonging PFS may preserve HRQoL.
