The Role of Cyclin-Dependent Kinase 4/6 Inhibitors Treatment in Oligometastatic Breast Cancer: A Case Report on a Possible Curative Intent Strategy.

ABSTRACT: A small but important subset of patients with metastatic breast cancer has an oligometastatic disease. Some of these patients are highly responsive to systemic therapy and have the potential to achieve complete remission with treatment. However, it remains to be clarified the best locoregional and systemic treatment strategy for such patients and what features can determine whose patients are the best candidates. We also don't know what will be the role of cyclin-dependent kinase 4/6 inhibitors in those cases. We report the case of a 41-year-old woman with HR-positive/HER2-negative oligometastatic breast cancer who, after an excellent response to systemic treatment with palbociclib, anastrozole, and goserelin, underwent breast surgery and liver metastasectomy. After completing three years of systemic treatment, the CDK inhibitor was discontinued, maintaining the hormone therapy. The patient remained under regular follow-up with no evidence of disease after eight months.
