Background: Trabectedin is a marine-derived chemotherapy, which has received U.S. Food and Drug Administration approval for use in anthracycline-resistant advanced soft tissue sarcoma (STS), especially liposarcoma and leiomyosarcoma (L-sarcomas).
Objectives: To describe our 10 year real-life experience with trabectedin regarding safety and efficacy in a cohort of 86 patients.
Methods: In our study cohort, 46.51% were diagnosed with liposarcoma and 43.02% with leiomyosarcoma. A total of 703 cycles of trabectedin were given, with a median of five cycles per patient (range 1-59). Median overall survival was 13.5 months for the whole cohort, 11 months for liposarcoma patients (range 1-63), and 15 months for leiomyosarcoma patients (range 1-35).
Results: There was no statistically significant difference in progression free survival when stratified according to previous treatment lines given. Trabectedin exhibited a favorable safety profile, with only 22% requiring dose reductions. Grade 3 and higher toxicity was noted in 25% of the patients, mostly due to myelosuppression. There were no treatment-related deaths.
Conclusions: Trabectedin is a safe and effective drug for treating advanced STS. Our results reflect real-life data with patients receiving the drug as a third and even fourth line of treatment, or with a suboptimal performance status, yet achieving impressive clinical benefit rates and survival.
