title: Challenging the platinum combinations in the chemotherapy of NSCLC.
abstract: In previously untreated patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) the combination of docetaxel and gemcitabine is active and well tolerated. In the phase II setting using a 3-week schedule, response rates (RR) ranged from 25 to 50%, and median survival from 11 to 13 months. Preliminary data with weekly and bi-weekly schedules indicate maintained efficacy while reducing the risk of neutropenia. A randomized phase III trial has shown that the combination of docetaxel and gemcitabine is as active as docetaxel plus cisplatin, achieving a 1-year survival rate of 39%, with significantly less neutropenia and gastro-intestinal toxicity. The combination of docetaxel with vinorelbine is equally active and the associated toxicities are manageable. In phase II studies the average response rate is 40%, and in one study using a 2-week schedule the 1-year survival rate was 60%. With this combination neutropenia is the commonest adverse event while clinically significant neuropathy is infrequent. In a randomized phase II trial, docetaxel plus cisplatin was compared to docetaxel plus irinotecan. The non-platinum doublet achieved comparable levels of activity, though with a different toxicity profile (more diarrhea but less nausea and vomiting). The combination of docetaxel with irinotecan and carboplatin has achieved 1-year survival of 55%. All three docetaxel combinations (gemcitabine, vinorelbine, and irinotecan) could provide a valuable alternative to platinum-based chemotherapy and should be further evaluated in phase III setting.
