Challenging the platinum combinations: docetaxel (Taxotere) combined with gemcitabine or vinorelbine in non-small cell lung cancer.
The limited single-agent activity of cisplatin, its toxicity profile, and the inconvenience involved in hydrating patients has compelled researchers to investigate other treatments as possible alternative therapies in non-small cell lung cancer. More recently, interest has focused on the potential of nonplatinum combinations. Phase II studies show that the combination of docetaxel (Taxotere; Aventis, Antony, France) and gemcitabine is active in stage IIIB/IV non-small cell lung cancer not previously treated by chemotherapy. Response rates of up to 54% and a median survival time of 13 months have been reported. These data are comparable with the achievements of cisplatin-based combinations. A randomized phase II trial of docetaxel plus gemcitabine versus docetaxel plus cisplatin found that the two regimens were equally active in terms of response rate, median, and 1-year survival. However, the combination of docetaxel with gemcitabine produced significantly less neutropenia and nonhematologic toxicities. In combination, from 80% to 100% of the full single-agent gemcitabine and docetaxel doses can safely be administered once every 3 weeks. The combination of docetaxel plus vinorelbine is also active in non-small cell lung cancer and preliminary data suggest that this schedule with prophylactic filgrastim may optimize tolerability and dose intensity. In a phase II study using this approach, a confirmed response rate of 51% was obtained in 35 patients. At 12 months, the predicted median survival is 14 months and the predicted 1-year survival rate is 60%. Excessive lacrimation, fatigue, and onycholysis were cumulative toxicities. However, the incidence of mucositis and neuropathy was low with the combination of docetaxel and vinorelbine. Docetaxel combined with other new agents, particularly gemcitabine, may offer another useful alternative to cisplatin-based chemotherapy in patients with good performance status.
