Evaluation of fludarabine phosphate in small cell carcinoma. A Southwest Oncology Group Study.

Fludarabine phosphate was given as a 5 day bolus infusion to eleven evaluable patients with recurrent small cell lung carcinoma. Patients had failed on one prior treatment regimen. There were no responses in the eleven evaluable patients. Severe neurologic toxicity occurred in one patient. Fludarabine phosphate as given in this protocol was not an effective agent in recurrent small cell lung carcinoma.
