Fludarabine phosphate. Phase II evaluation in advanced soft-tissue sarcomas

Fludarabine phosphate (NSC-312878) was administered to 23 patients with advanced soft-tissue sarcomas. Patients entered on the study had a median performance status of 80 and had prior chemotherapy restricted to one previous regimen. Dose schedule was 100 mg/m2 in poor-risk patients (creatinine clearance less than 70 cc/min) and 125 mg/m2 in good-risk patients every 3 weeks. No complete or partial responses were noted in the 20 evaluable patients. Median survival was 12 weeks. Leukopenia was the most common toxicity. Fludarabine phosphate in the above schedule failed to demonstrate therapeutic efficacy in this patient population.
