A phase II study of paclitaxel combined with infusional 5-fluorouracil and low-dose leucovorin for advanced gastric cancer

Purpose: The aim of this study was to investigate the efficacy and safety of the combination chemotherapy of paclitaxel, infusional 5-fluorouracil (5-FU) and leucovorin (FLT regimen) in advanced gastric cancer. The primary end point was the time to progression (TTP). Methods: Patients with evaluable disease with or without measurable lesions received 175 mg/m² paclitaxel on day 1 followed by 20 mg/m² leucovorin and 24-h infusion of 5-FU 1,000 mg/m² (day 1-3) repeated every 3 weeks. Results: Sixty patients were enrolled. The median TTP and overall survival duration were 13 and 60 weeks, respectively. One-year survival rate was 53.3%. Of the 50 patients with measurable lesion, the overall response rate was 31.7%. The most common grade 3-4 adverse event was neutropenia (61.7%). Conclusion: The FLT regimen showed an efficacy comparable to other regimens of cisplatin or anthracycline combinations with the advantage of remarkably low non-hematological toxicity. These data about the efficacy of this regimen need confirmation in a phase III trial.
