Abstract

Palbociclib, an oral small-molecule inhibitor of cyclin-dependent kinases 4 and 6, was recently approved by the U.S. Food and Drug Administration in combination with letrozole for postmenopausal women with advanced hormone receptor–positive, her2-negative breast cancer. Patients with loss of CDKN2A (p16), an inherent negative regulator of cyclin-dependent kinases 4 and 6, were not separately studied because of the significant response of the patients selected based only on receptor status. Here, we report a patient with metastatic estrogen receptor–positive, her2-negative breast cancer with CDKN2A loss who experienced a clinical response to palbociclib.
