One-hour paclitaxel plus carboplatin in the treatment of advanced non-small cell lung cancer: Results of a multicentre, phase II trial

The aim of this phase II study was to determine the activity and toxicity of paclitaxel (administered by l-h infusion) and carboplatin in advanced non-small cell lung cancer when used in a multicentre, community-based treatment setting. 100 chemotherapy-naive patients with stage IIIB or IV non-small cell lung cancer were treated between March 1995 and February 1996. All patients had Karnofsky performance status 70-100, measurable disease and adequate bone marrow, kidney and Liver function. All patients received intravenous (i.v.) paclitaxel 225 mg/m(2) by l-h infusion followed immediately by carboplatin at a targeted area under the concentration time curve (AUC) of 6.0 using the Calvert formula. Courses were repeated every 21 days. Colony stimulating factors were not used routinely. 38 of 94 evaluable patients (40%) had objective responses to treatment (3 complete responses, 35 partial responses). An additional 32 patients had stable disease at initial re-evaluation. Weight gain during treatment was experienced by 47% of patients with objective response or stable disease. The median survival in this group of 100 patients was 8 months, with an actuarial 1-year survival of 42%. Leucopenia was common, but hospitalisation for treatment of neutropenia and fever occurred in only 3% of courses. Cumulative peripheral neuropathy was common, but usually appeared after the third or fourth course and was severe (grade 3) in only 15% of patients. Other grade 3 and 4 toxicity was uncommon. There was one treatment-related death due to sepsis. This large multicentre community-based phase II trial demonstrated the efficacy of paclitaxel and carboplatin combination chemotherapy in advanced non-small cell lung cancer. When paclitaxel is given by l-h infusion, this regimen is easily administered in the outpatient setting. (C) 1998 Elsevier Science Ltd. All rights reserved.
