Efficacy and tolerability of trabectedin in heavily pretreated soft tissue sarcomas (STS).
2017
e20513 Background: Advanced STS have a dismal prognosis with a median overall survival of 1 year, reported in most phase III clinical trials. Although newer targeted therapies are currently being evaluated, chemotherapy continues to be the mainstay of treatment. However, due to the limited activity of current treatments, new therapies are needed. Trabectedin, an alkylating agent to the minor groove of DNA, has demonstrated significant activity after failure of anthracyclines and ifosfamide. Methods: This is a retrospective analysis of 22 patients diagnosed with advanced, heavily pretreated STS, treated with trabectedin in a single institution. From 06/ 2000 to 06/ 2011, trabectedin was administered as a 3-hour infusion every 21 days at a dose of 1.1-1.5mg/m2 with steroid premedication. No patients were excluded from this analysis. Results: Median age was 53 years (range 21-82). The most frequent histologic subtypes were: 27% liposarcomas, 18% leiomyosarcomas, 13% malignant fibrous histiocytomas and 9% syn...
