Randomized phase II trial of cisplatin and radiotherapy with or without erlotinib in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN).
2012
5503 Background: The combination of cisplatin and radiotherapy is a standard treatment for patients with locally advanced SCCHN. Cetuximab-radiotherapy is superior to radiotherapy alone in this population, validating EGFR as a target. Erlotinib, a small molecule inhibitor of EGFR, has activity in recurrent/metastatic disease. Adding EGFR inhibition to standard cisplatin-radiotherapy may improve efficacy. Methods: Patients with locally advanced SCCHN were randomized to receive cisplatin 100mg/m2 on days 1,22 and 43 combined with 70Gy of radiotherapy (arm A) or the same chemoradiotherapy combined with erlotinib 150mg/day, starting one week prior to radiotherapy and continued to its completion (arm B). Randomizing 204 patients had 80% power to compare a 60% complete response rate (CRR) to a 40% null rate. Available tumors were tested for p16, ERCC1 and EGFR FISH. Results: Between June 2006 and October 2011, 204 patients were randomized. Results presented are based on intention to treat. There were more femal...
