Phase I trials have established the standard regimen as 1500 µg/m² 24-hour continuous infusion repeated every 3 weeks. Several phase II trials have shown response in 5%–10% of unselected patients with soft tissue sarcoma failing prior chemotherapy and disease stabilisation in 30%–40%. Furthermore, prolonged disease control has been described in 15%–20% of patients. Toxicities are mainly haematological and hepatic with grade 3–4 neutropenia and thrombocytopenia observed in approximately 50% and 20% of patients respectively, and grade 3–4 elevation of liver enzymes observed in 35%–50% of patients treated with trabectedin. Current research focuses on the identification of predictive factors for patients with soft tissue sarcoma treated with trabectedin.Keywords: chemotherapy, sarcoma, drug development, DNA repai
