Resumen | Background: In the FLIPPER trial, palbociclib/fulvestrant significantly improved progression free survival (PFS) compared with placebo/fulvestrant in postmenopausal women with HR+/
HER2− advanced breast cancer (ABC).
Objective: ... Background: In the FLIPPER trial, palbociclib/fulvestrant significantly improved progression free survival (PFS) compared with placebo/fulvestrant in postmenopausal women with HR+/ HER2− advanced breast cancer (ABC). Objective: We assessed health-related quality of life (QoL) using patient-reported outcomes (PROs). Design and methods: In this phase II double-blinded study, PROs were assessed at baseline after every three cycles and at the end of the treatment using the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23. Time to deterioration (TTD) in global health status (GHS)/QoL was defined as a decrease of ⩾10points. Changes from baseline (CFB) and TTD were analysed using linear mixed-effect and Cox regression models, respectively. Results: Of the 189 randomised (1:1) patients, 178 (94%) completed ⩾1 post-baseline assessment; 50% received ⩾22 cycles of study treatment, with a questionnaire compliance >90%. Mean baseline scores were comparable between arms. GHS/QoL scores were maintained throughout the palbociclib/fulvestrant treatment. CFB showed significant differences for GHS/QoL, appetite loss, constipation and systemic therapy side effect scores favouring placebo/fulvestrant. TTD in GHS/QoL was delayed in placebo/fulvestrant versus palbociclib/fulvestrant [30.3 versus 11.1months; adjusted hazard ratio (aHR): 1.57, 95% CI: 1.03–2.39, p=0.036]; this difference was not significant in patients with progressive disease (aHR: 1.2, 95% CI: 0.6–2.2, p=0.658). No statistically significant differences in TTD were found for the other QLQ-C30 and QLQ-BR23 scales. Conclusions: Although TTD in GHS/QoL was prolonged with placebo/fulvestrant, no differences were observed on other functional or symptom scales. This finding and the improvement in PFS support the combination of palbociclib/fulvestrant as a beneficial therapeutic option for HR+/HER2− ABC. |
