Induction chemotherapy with ifosfamide, etoposide, and anthracycline for small cell lung cancer: experience of the European Lung Cancer Working Party.

Prospective trials comparing drug analogues in the treatment of small cell lung cancer are rare. The European Lung Cancer Working Party has conducted a randomized trial with a primary end point of determining the effect on survival of maintenance chemotherapy and a secondary end point of comparing doxorubicin (45 mg/m2) with a bioequivalent epirubicin dose (60 mg/m2) in one set of patients, and a standard with a high epirubicin dose (60 v 90 mg/m2) in a second set of patients. Anthracycline was given on day 1 of induction chemotherapy in combination with ifosfamide (1.5 g/m2 intravenously days 1 through 3) and etoposide (80 mg/m2 intravenously days 1 through 3). Six courses were given at 3-week intervals. In all, 235 eligible previously untreated patients with pathologically proven small cell lung cancer were randomized: 106 to the comparison of doxorubicin and epirubicin and 129 to the comparison of standard-dose versus high-dose epirubicin. There was no difference between the regimens in terms of objective response rate or survival, and the regimen containing the lower (60 mg/m2) epirubicin dose was better tolerated, with fewer toxic deaths and less need for dose and schedule adjustments.
