title: Novel approaches with ifosfamide in small cell lung cancer.
abstract: During the past 5 years, ifosfamide has been used increasingly in combination chemotherapy for small cell lung cancer (SCLC). The high activity and favorable toxicity spectrum (with the uroprotector mesna) will encourage further use. A policy of no dosage reduction is feasible in patients receiving combination chemotherapy with ifosfamide given as a 24-hour intravenous (IV) infusion, which is much more convenient than the more commonly used 4- to 5-day fractionated regimen. This policy has resulted in actual 2-year survivals of 22% to 33% among SCLC patients not intensively staged. The stability of ifosfamide and its high bioavailability have allowed its use in chronic, 7-day ambulatory IV infusions, with decreased toxicity and hospitalization. Recently, oral and subcutaneous administration also have been tried, again allowing outpatient treatment. The first studies with hemopoietic growth factor support, eg, granulocyte colony-stimulating factor, conducted with combination chemotherapy with ifosfamide-containing regimens in SCLC, demonstrated significant reduction in neutropenia, infections, and antibiotic use. It is clear that the dosage of ifosfamide can be intensified in the future. The broad versatility of the drug will allow interesting new studies, including those to be conducted with outpatients.
