INITIAL RESULTS OF A PHASE I DOSE-ESCALATION TRIAL OF CONCURRENT AND MAINTENANCE ERLOTINIB AND REIRRADIATION FOR RECURRENT AND NEW PRIMARY HEAD-AND-NECK CANCER
International Journal of Radiation Oncology Biology Physics (2010) 78:1020-1025.
Abstract
Purpose: To present the first report of a Phase I trial evaluating concurrent and maintenance erlotinib and reirradiation in patients with recurrent or secondary primary head-and-neck cancer (HNC). Methods and Materials: Patients with recurrent or new primary HNC with an interval of at least 6 months since prior radiation were eligible. Patients were treated in 3 sequential cohorts: Cohort I, 100 mg of erlotinib daily with reirradiation at 61.6 Gy in 28 fractions; Cohort II, 150 mg of erlotinib with 61.6 Gy in 28 fractions; and Cohort III, 150 mg of erlotinib with 66 Gy in 30 fractions. Maintenance erlotinib started immediately after reirradiation at 150 mg daily and was continued for 2 years or until disease progression or dose-limiting toxicity. Dose-limiting toxicities were defined as any Grade 4 or 5 toxicity or a toxicity-related delay in radiation therapy of greater than 7 days. Results: Fourteen patients were accrued, 3 to Cohort I, 4 to Cohort II, and 7 to Cohort III. Thirteen patients were evaluable for toxicity. Median follow-up was 8.4 months overall and 15.1 months for surviving patients. One patient had a dose-limiting toxicity in Cohort III. This patient declined initial percutaneous endoscopic gastrostomy tube placement, was hospitalized with Grade 3 dysphagia and aspiration, and required a delay in radiation therapy of greater than 7 days. No Grade 4 acute toxicity was observed. Acute Grade 3 toxicity occurred in 9 of 13 patients. No erlotinib-related toxicity of Grade 3 or greater was observed during maintenance therapy. One patient had Grade 5 carotid hemorrhage 6 months after reirradiation, and another patient had Grade 3 osteoradionecrosis. Conclusions: Reirradiation (66 Gy in 2.2 Gy fractions) with concurrent and maintenance erlotinib (150 mg daily) for recurrent or new primary HNC is feasible. (C) 2010 Elsevier Inc.
