Phase II trial of 6-thioguanine administered as 120 hour continuous infusion for refractory or recurrent small cell lung cancer. A Southwest Oncology Group study.
Nineteen eligible patients with recurrent small cell lung cancer were treated with a 120 hour continuous infusion of 6-thioguanine at a starting dose of 35 mg/m2/day. There were no responses in these 19 patients. Toxicity was acceptable with the primary toxicity being hematologic. Based on this trial, 6-thioguanine is not felt to have significant antitumor activity in this patient population.
