Summary
Brief summary (as posted)
Hormone therapy is the primary treatment option for patients with HR+ HER2- breast cancer. Despite its activity, hormone therapy is associated with initial, or more frequently acquired, resistance after exposure to one or more treatment lines. The combination of palbociclib with hormone therapy significantly increases progression free survival (PFS) compared with hormone therapy in first and second treatment line of HR+ HER2- advanced breast cancer. These results lead to palbociclib approval by the Food and Drug Administration (FDA) in February 2015, and European Medicines Agency (EMA) approval in November 2016 for first-line treatment of patients with metastatic HR+/HER2-breast cancer in combination with an aromatase inhibitor, and for patients who had previously received hormone therapy in combination with fulvestrant. In Spain, palbociclib was launched last November 1st, 2017. During this period, approximately 3500 patients have received treatment with Palbociclib, and approximately a half of them in first-line treatment in combination with hormone therapy. The collection of efficacy and toxicity data in the first-line usage in the clinical practice setting is of clinical interest.
