Epirubicin in previously untreated patients with small cell lung cancer: a phase II study by the EORTC Lung Cancer Cooperative Group.

Overview

Epirubicin 110 mg/m2 was administered intravenously every 3 weeks to 41 elderly and/or unfit, previously untreated patients with small cell lung cancer (SCLC). There were three complete responses, 16 partial responses and 14 treatment failures, with a response rate of 57% in 33 evaluable patients. The main toxicity was haematological, characterised by leukopenia and, less frequently, thrombocytopenia and anaemia. There were three toxic deaths due to infection occurring during leukopenia. Non-haematological side effects were alopecia, nausea, stomatitis and diarrhoea. WHO grade 2 cardiac toxicity was seen in 3 patients after a cumulative dose of more than 740 mg/m2. In conclusion epirubicin is an active agent in untreated SCLC.
