During the last decades, the introduction of new cytotoxics and targeted therapies resulted in a prolongation of survival and a minimization of toxicity in the treatment of metastatic breast cancer. However, to date, there was no standard of care following second-line therapy in this setting. In Phase III EMBRACE study, eribulin obtained a statistically significant improvement in the overall survival of pretreated metastatic breast cancer patients. This case report describes a heavily chemo-pretreated woman with important bone, nodal, hepatic and choroidal involvement from breast cancer who had a remarkable, unexpected and lasting disease response after treatment with eribulin. This case underlines how this well-tolerated monochemotherapy may be able to obtain a prolonged disease control and a good clinical outcome.
