Background: The FAST is a 2 × 2 factorial trial addressing two questions: (1) the role of replacing cisplatin (P) with a non-platinum agent, vinorelbine (N), and (2) the role of adding a third agent, ifosfamide (I), in a doublet based on gemcitabine (G)., Methods: A total of 433 stage IIIB-IV non-small cell lung cancer (NSCLC) patients were randomised to one of four arms: gemcitabine-cisplatin (GP), gemcitabine-vinorelbine, gemcitabine-ifosfamide-cisplatin or gemcitabine-ifosfamide-vinorelbine. Two comparisons were performed: N- vs P-containing regimens and I-triplets vs non-I doublets., Results: For N- vs P-containing regimens, adjusted overall survival was 9.7 vs 11.3 months (P=0.044), progression-free survival was 4.9 vs 6.4 months (P=0.020) and response rate was 24% vs 31% (P=0.124), respectively. No statistically significant difference was observed between doublets and triplets. Grade 3-4 haematological toxicity was significantly more frequent in P-containing therapy; grade 3-4 leucopenia was significantly more common in triplets. Concerning non-haematological toxicity, grade 3-4 nausea-vomiting was significantly increased in P-containing regimens., Conclusions: This trial provides evidence of a slight survival superiority of GP-containing regimens over platinum-free N-containing chemotherapy. This trial also confirms that the addition of a third chemotherapy agent (I) to a standard G-based doublet does not improve treatment outcome.

Thirty-four patients with previously untreated advanced non-small-cell lung cancer were treated with a combination of polychemotherapy and recombinant interferon. Chemotherapy consisted of cyclophosphamide, 400 mg/m2, epidoxorubicin, 50 mg/m2, and cisplatin, 40 mg/m2 (CAP) i.v. on day 4; recombinant alpha 2b interferon (r alpha 2b IFN) was given i.m. daily at the dose of 3-5 MU from days 1 to 7. The treatment was repeated every 4 weeks. In the 32 eligible patients the overall response rate was 19.3% (95% C.L. 7.4-37.4%). Non-hematologic toxicity consisted formerly in flulike symptoms and fatigue complained of by 37.5% and 31.2% of patients, respectively, and vomiting reported in 68.7% of patients; grade III-IV myelotoxicity was observed in 12.5% of cases. In no case was the toxicity life threatening. The median overall actuarial survival and progression-free survival were 37 and 20 weeks, respectively. This study indicates that the combination of CAP chemotherapy and r alpha IFN is feasible and active in the treatment of advanced non-small-cell lung cancer.
