Docetaxel and radiation as combined-modality therapy.
Combined-modality approaches for the treatment of non-small-cell lung cancer (NSCLC), head and neck cancer, and esophageal cancer offer survival benefits by improving locoregional control and treating micrometastatic disease. The taxanes are active, tolerable drugs in these solid tumors and have radiation-sensitizing activity. Docetaxel (Taxotere) has been studied in combination with radiation with favorable results. In phase II trials, docetaxel combined with radiation therapy resulted in response rates of up to 80%, with the most commonly used schedule being docetaxel at 20 to 30 mg/m2 per week with concomitant radiation administered at fractions of 1.8 to 2.0 Gy, 5 days a week over 5 to 6 weeks. Studies of docetaxel and platinum combinations have been conducted predominantly in patients with NSCLC. Early results show good activity and acceptable toxicity, with esophagitis or mucositis being dose-limiting. Doses of docetaxel at 20 mg/m2 per week combined with cisplatin at 25 mg/m2 or carboplatin (Paraplatin) at an area under the concentration-time curve (AUC) of 2 with concomitant radiation appear to be well tolerated and active. Future investigations, including phase III trials in patients with locally advanced NSCLC, are encouraged. Current trials are studying various design schedules, including induction chemotherapy with radiation followed by consolidation chemotherapy.
