PURPOSE: To evaluate the efficacy and toxicity of oxaliplatin and paclitaxel as first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: The treatment regimen was given as defined in a phase I investigation in patients with previously treated ovarian cancer. It consisted of paclitaxel 175 mg/m(2) (1-h infusion) and oxaliplatin 130 mg/m(2) (2-h infusion) given every 21 days. Eligible patients had stage IIIB (pleural effusion)/IV NSCLC, measurable disease, no prior chemotherapy, Eastern Cooperative Oncology Group performance status 0-2, and adequate hematological, renal and hepatic function. RESULTS: A total of 38 patients were enrolled with the following characteristics: 29% male (n = 11); 71% female (n = 27); median age 64.5 years (range 37-78); performance status of 0-1 84% (n = 32); stage IIIB 8% (n = 3); stage IV 92% (n = 35). One hundred and eighty-one cycles were administered, with a median of four per patient (range one to 12). The overall objective response rate for all 38 patients was 34.2% [95% confidence interval (CI) 19.6% to 51.4%]. This response rate includes 13 patients who met criteria for a partial response. No complete responses were observed. Median overall survival time was 9.2 months (95% CI 6-12.4) and median progression-free survival time was 4.3 months (95% CI 2.1-6.5). The 1- and 2-year overall survival rates were 37% and 21%, respectively. Hematological toxicity included six patients with grade 4 neutropenia. Non-hematological toxicity consisted mainly of grades 1 and 2 neurosensory toxicity. Laryngodysesthesia was observed in two patients following oxaliplatin infusion. No grade 4 non-hematological toxicities were encountered. CONCLUSION: This regimen is well tolerated, and demonstrates activity in patients with advanced NSCLC.
