Clinical Trial
Thoracic radiotherapy and daily vinorelbine as radiosensitizer in locally advanced non small cell lung cancer: a phase I study.
Experimental studies have shown that vinorelbine is a powerful radiosensitizer in vitro. To date, no reports on clinical activity of the single agent vinorelbine as radiosensitizer have been published. The aim of the present phase I study was to determine the maximum tolerated dose (MTD) of vinorelbine administered daily concurrently with thoracic radiotherapy, with or without amifostine support, in the treatment of locally advanced non small cell lung cancer. ⋯ In conclusion, our data show that the MTD of daily vinorelbine is 4 mg/m(2). Therefore, this is the recommended dose of daily vinorelbine to be administered with concurrent thoracic radiotherapy in a phase II trial. Finally, amifostine administered subcutaneously failed to increase the MTD of daily vinorelbine.
