Abstract
The aim of this randomized multicenter phase III trial was to compare chemotherapy and interferon in patients with metastatic carcinoid tumors. Patients with documented progressive, unresectable, metastatic carcinoid tumors were randomized between 5FU plus streptozotocin (day1 to day5) and recombinant interferon alpha 2a (3MU x 3 per week). Primary endpoint was progression-free survival (PFS). From February 1998 to June 2004, 64 patients were included. The two arms were well matched for median age, sex ratio, PS 0-1, previous chemotherapy, surgery or radiotherapy. The median PFS for chemotherapy was 5.5 months versus 14.1 for interferon (HR = 0.75 [0.41-1.36]). Overall survival (OS), tolerance and effects on carcinoid symptoms were not significantly different. Despite a trend in favor of IFN there was no difference in PFS and OS in advanced metastatic carcinoid tumors and therapeutic effect of both treatments was mild.
