Ifosfamide in non-small cell lung cancer.

In recent years the role of chemotherapy in advanced non-small cell lung cancer (NSCLC) has been well established. Ifosfamide is an old drug still considered an effective cytostatic agent in the treatment of NSCLC. As a single agent, it has showed a response rate of 20-25%. These results are improved when it is used in combination with cisplatin and mitomycin C. Moreover, in recent years, several new drugs like gemcitabine, taxanes and vinorelbine have been identified, and combinations of two or three drugs have been tested in patients with advanced NSCLC. This paper reviews the main studies recently conducted for the treatment of NSCLC, considering the results obtained by ifosfamide alone and in combination. Three-drug regimens including first-generation cytostatic agents achieve a response rate of about 40% and median survival of 10 months. In combinations with new drugs, ifosfamide shows an improvement in response rate (50%) with a median survival of more than 1 year. Open questions in the treatment of NSCLC are whether three-drug are better than two-drug combinations, and whether cisplatin is still required. Copyright 2003 S. Karger AG, Basel
