Letrozole And Palbociclib In Advanced Breast Cancer: Outcome From Cancer Institute, Chennai
INDIAN JOURNAL OF MEDICAL AND PAEDIATRIC ONCOLOGY(2020)
Abstract
Background: Cyclin-dependent kinase 4/6 inhibitor addition to hormonal therapy has shown to improve the survival of hormone receptor (HR)-positive, HER2-negative advanced breast cancer (ABC). Methods: We retrospectively analyzed untreated patients with HR-positive, HER2-negative ABC, who received letrozole and palbociclib at the Cancer Institute, Chennai, from October 2017 to January 2019. Results: A total of 24 patients were included in this study. The median progression-free survival (PFS) was 18 months, and the median overall survival (OS) had not reached. The 1-year PFS and OS were 73.7% and 89.2%, respectively. The common toxicities were neutropenia and fatigue but none of the patients had febrile neutropenia. Conclusion: Letrozole-Palbociclib is effective with manageable toxicity as the first-line treatment for HR-positive, HER2-negative ABC.
