Delayed use of eribulin in a heavily pretreated liposarcoma patient, previously misdiagnosed as leiomyosarcoma.

Due to its low incidence, liposarcoma displays a limited number of therapeutic options. However, eribulin recently received approval for the treatment of advanced liposarcoma patients, progressing to at least two chemotherapy lines. We report herein the case of a man initially diagnosed with a leyomiosarcoma, subsequently reclassified as a dedifferentiated liposarcoma, who received eribulin after he failed several therapy lines. Eribulin provided our patient an 8-month disease control and a substantial clinical benefit with no relevant adverse effects, showing a good efficacy and safety profile despite its delayed employ. Additionally, this case strengthens the pivotal importance of molecular profiling in the management of soft tissue sarcomas.
