AIM: We report our experience with eribulin mesylate in a pancytopenic heavily pretreated patient with multiple bone metastases and bone marrow infiltration from breast cancer. METHODS: Eribulin mesylate was given at 1.4 mg/m(2) on day 1 and 8 every 3 weeks for a total of 11 courses. RESULTS: After seven cycles, evaluation with a bone marrow biopsy showed a large decrease of neoplastic involvement with substitution of osteolitic lesions for the osteoaddensant type. No unexpected acute toxicity was observed. CONCLUSION: To our knowledge, this represents the first report of bone marrow metastases from breast cancer treated with eribulin mesylate that obtained an improvement of hematopoietic values with an acceptable profile of tolerability and good compliance for the subject.
