Chemotherapy With Eribulin Following Potentially Curative Surgery in Patients With Localized Liposarcoma.

ABSTRACT

BACKGROUND/AIM: Soft tissue sarcomas are rare and heterogenous malignancies with high recurrence rates following resection and a poor prognosis in advanced stages. Eribulin is used in metastatic soft tissue sarcoma patients, who have failed first line chemotherapy and has been approved for patients with pretreated advanced liposarcoma (LPS) in the United States and Europe following the publication of data of a phase III trial. In addition, no data are available for eribulin as postoperative treatment after potentially curative surgery. We, thus, retrospectively evaluated efficacy and tolerability of adjuvant eribulin in patients with LPS not suitable for intensive chemotherapy in the routine clinical setting. PATIENTS AND METHODS: In this retrospective single center analysis, efficacy and safety of eribulin were retrospectively evaluated in five high risk LPS patients. RESULTS: Eribulin as treatment was administered to five patients with LPS following surgical resection. Median progression-free survival and overall survival were 12.3 months and 44.3 months, respectively. Toxicity was generally manageable, and grade 3+4 events were rare. CONCLUSION: Postoperative eribulin may be feasible in selected high risk LPS patients, who are not candidates for intensive chemotherapy regimens. Further prospective trials, however, are needed.
