A total of 63 articles (on anthracyclines, ifosfamide, trabectedin and 27 investigational agents) were included (data from 1979 to 2008).Trabectedin is the most extensively studied agent in patients with STS after failure of anthracyclines and ifosfamide (457 patients), followed by ifosfamide (412), cisplatin (144), temozolomide (137), docetaxel (114), gemcitabine (112), etoposide (95) and doxorubicin (59). Dacarbazine and the remaining investigational agents have usually been tested in 50 or fewer patients, with vastly negative results not warranting further investigation.
