Abstract
Background: Limited studies have evaluated palbociclib-based therapy use in patients with advanced/metastatic breast cancer in the real world. This retrospective study used medical records from US community oncology practices to address the gap. Materials & methods: Eligible patients receiving palbociclib-based therapy per label indication from 3 February 2015 to 31 December 2017 were included. Descriptive analyses were conducted for patient characteristics, treatment patterns and clinical outcomes. Results: The study included 233 patients who received palbociclib + aromatase inhibitor (P+AI) and 48 who received palbociclib + fulvestrant (P+F). Real-world progression-free rate for P+AI was 69.8% (46.8%) at 12 (24) months (P+F: 43.5% [39.9%]) months. Real-world survival rate was 89.8% (71.4%) at 12 (24) months (P+F: 76.3% [65.0%]). Conclusion: The study findings are consistent with previous studies of palbociclib-based therapy.
