Metastatic Liposarcoma: A Case of Partial Remission with Eribulin in Late Treatment Lines

Abstract

Viktor Grunwald and Philipp Ivanyi

Liposarcoma, a type of soft tissue sarcoma, represents a therapeutic challenge, in particular in the metastatic setting. This case describes a patient with retroperitoneal liposarcoma that was first treated by surgery and, upon manifestation of metastatic disease, with a series of chemotherapy regimens comprising doxorubicin (line 1), doxorubicin plus ifosfamide (line 2), trabectedin (lines 3 and 4) and dacarbazine (line 5). While transient partial remission was achieved in the first three lines, rapid disease progression was observed in subsequent therapies. After failure of the previous chemotherapy regimens, eribulin was administered (line 6), and partial remission was achieved within five months. However, the occurrence of grade 3 polyneuropathy led to temporary discontinuation of therapy. Overall, metastatic liposarcoma was controlled for twelve months with eribulin treatment in a heavily pre-treated patient. This case underscores the efficacy of eribulin in treatment-refractory advanced/metastatic liposarcoma.
