Gemcitabine administered as a short infusion versus a fixed dose rate in combination with cisplatin for the treatment of patients with advanced non-small cell lung cancer

SummaryPrevious studies have indicated that, in combination with cisplatin, fixed dose rate gemcitabine may be more efficacious than standard infusion gemcitabine. This open-label, randomised phase II study was aimed to compare the efficacy and safety of these regimens as treatment for advanced non-small cell lung cancer (NSCLC) in Latin American patients.Sixty-four patients were randomised to receive up to six cycles of treatment with cisplatin 75 mg/m2 on Day 1 plus either gemcitabine 1000 mg/m2 over 30 min on Days 1 and 8 of a 21-day cycle (standard arm, N = 33) or gemcitabine 1000 mg/m2 at a fixed dose rate of 10 mg/m2/min on Days 1 and 8 of a 21-day cycle (FDR arm, N = 31). In the standard arm, 9 of 33 (27%) patients responded compared with 6 of 30 (20%) patients in the FDR arm (odds ratio: 0.67, 95% CI, 0.21–2.2; p = 0.56). Median overall survival was 7.5 months in the standard arm and 9.9 months in the FDR arm. One-year survival rates were 35% and 37% in the standard arm and the FDR arm, respectively. Patients in the FDR arm experienced more grade 3/4 haematological toxicity than those in the standard arm (48% versus 21%). The results of this trial do not support FDR administration of gemcitabine in preference to the standard administration in Latin American patients with NSCLC.
