Retinal metastasis regression with eribulin in a heavily pretreated breast cancer patient

The authors present the case of a heavily pretreated young woman with retinal and brain metastases from breast cancer who was successfully treated with eribulin. Eribulin was given at 1.1 mg/m2 on day 1 and 8, every 3 weeks for a total of 12 courses. A significant reduction in the size of brain and retinal lesions was achieved after three cycles. The treatment was continued for 12 cycles, with a good profile of tolerability. In this clinical case, eribulin demonstrated to be active on brain and retinal metastases from breast cancer, although preclinical data showed limited ability to cross the blood–brain barrier.
