Purpose: To determine the maximum-tolerated dose (MTD) and dose-limiting toxicities of paclitaxel administered weekly on an outpatient basis with concurrent thoracic radiation to patients with advanced non-small-cell lung cancer (NSCLC). Patients and Methods: In this phase I clinical trial, paclitaxel was administered as a 3-hour intravenous (IV) infusion, repeated every week for 6 weeks. The starting dose of paclitaxel was 10 mg/m2. Doses were escalated at 10-mg/m2 increments in successive cohorts of three new patients if tolerated. Unacceptable toxicity was defined as grade 3 nonhematologic toxicity, excluding nausea and vomiting, and grade 4 hematologic toxicity according to Cancer and Leukemia Group B expanded common toxicity criteria. Radiation was administered to the primary tumor and regional lymph nodes (40 Gy) followed by a boost to the tumor (20 Gy). Results: Twenty-seven patients were entered onto this study through seven dose escalations (from 10 mg/m2/wk to 70 mg/m2/wk for 6 weeks). Severe esophagitis occurred at 70 mg/m2 (two patients with grade 4 disease and one patient with grade 2). One of six patients at 60 mg/m2 developed grade 3 esophagitis and three of seven patients had grade 2 esophagitis. One of 27 patients developed a hypersensitivity reaction. One of 27 patients developed grade 3 neutropenia. Conclusion: Esophagitis is the principle dose-limiting toxicity of weekly paclitaxel and thoracic radiation in the outpatient setting. A phase II trial using concurrent radiation and paclitaxel at the MTD of 60 mg/m2/wk is underway.
