One-Hour Paclitaxel Plus Carboplatin for Advanced Non-Small-Cell Lung Cancer

January 2nd 1998

We report here the preliminary results of a large phase II multicenter study done in the community setting, using paclitaxel (Taxol) (given by 1-hour infusion) plus carboplatin (Paraplatin) to treat patients with advanced non-small-cell lung cancer (NSCLC). In this study, 155 chemotherapy-naive patients with stage IIIB, stage IV, or recurrent metastatic non-small-cell lung cancer received the two drugs in 21-day cycles. Paclitaxel 225 mg/m² was given by 1-hour intravenous infusion followed immediately by carboplatin at a targeted area under the concentration-time curve of 6.0 (calculated according to the Calvert formula). Colony-stimulating factors were not used routinely. Objective responses occurred in 53 of 155 patients (34%) (53 of 144 [36%] evaluable patients) including three complete responses and 50 partial responses. Fifty-two other patients had stable disease at initial reevaluation. The median survival among all 155 patients was 8 months; the 1-year survival rate was 42%, and the 2-year survival rate was 20%. Leukopenia and cumulative peripheral neuropathy occurred consistently but rarely were severe or affected the course of therapy. One patient died due to sepsis. Other grade 3 and grade 4 toxicities were uncommon. This paclitaxel-carboplatin combination chemotherapy appears to be a relatively convenient, safe, and active regimen in advanced non-small-cell lung cancer.[ONCOLOGY 12(Suppl 2):71-73, 1998]
