Cisplatin and irinotecan (CPT-11) as second-line treatment in patients with advanced non-small cell lung cancer.
Irinotecan (CPT-11) and cisplatin (P) are both active agents against non-small cell lung cancer (NSCLC), and their combination has shown in vitro an additive or synergistic effect. We conducted a phase II study to determine the toxicity and efficacy of their combination as salvage treatment in patients with advanced NSCLC progressing after a docetaxel-based front line regimen. Forty-four patients with histologically confirmed NSCLC were enrolled. The patients' median age was 60.5 years; 39 patients (87%) were male; 38 (86%) had stage IV disease; and 32 (73%) had a performance status (WHO) 0-1. CPT-11 was administered as a 60 min i.v. infusion at a dose of 100 mg/m(2) on day 1 and 110 mg/m(2) on day 8; P was administered at a dose of 80 mg/m(2) on day 8 after CPT-11 administration. Treatment was repeated every 3 weeks. A total of 159 chemotherapy cycles was administered. In an intention-to-treat analysis, nine patients (22; 95% CI: 9.28-34.62%) achieved a partial response (PR), 8 (20%) had stable disease (SD), and 24 (58%) progressive disease (PD). The median duration of response was 4 months, the median time-to-progression (TTP) 8 months, and the median survival for the entire group 8 months. Grade 3-4 neutropenia was observed in 20 (46%) patients and in four cases this was febrile, requiring patient's hospitalisation. Grade 3-4 thrombocytopenia occurred in four (9%) patients. Grade 3-4 diarrhoea was seen in 12 (27%) patients and three of them required hospitalisation. Grade 2-3 neurotoxicity was observed in two (4%) patients and grade 2-3 fatigue in 14 (32%). Other toxicity was mild and no treatment-related death was reported. The combination of CPT-11 and P is a safe, well-tolerated, and active regimen for the treatment of patients with advanced NSCLC previously treated with a docetaxel-based front-line regimen.
