Phase II Study of Low-Dose Paclitaxel and Cisplatin in Combination With Split-Course Concomitant Twice-Daily Reirradiation in Recurrent Squamous Cell Carcinoma of the Head and Neck: Results of Radiation Therapy Oncology Group Protocol 9911

Abstract
Purpose Recurrent squamous cell carcinoma of the head and neck (SCCHN) or new second primary tumor (SPT) in a previous radiation field, if not curable by surgery or radiation, is almost always fatal. Chemotherapy alone yields a median survival time (MST) of no more than 10 months and 1-year overall survival (OS) of 35% at best. Concurrent reirradiation and chemotherapy is an alternative strategy. Patients and Methods Eligibility for Radiation Therapy Oncology Group (RTOG) protocol 9911 stipulated recurrent SCCHN or SPT in a previous radiation field. Patients received twice-daily radiation (1.5 Gy per fraction bid × 5 days every 2 weeks ×4), plus cisplatin 15 mg/m2 intravenously (IV) daily × 5 and paclitaxel 20 mg/m2 IV daily × 5 every 2 weeks ×4. Granulocyte colony-stimulated factor was administered days 6 through 13 of each 2-week cycle. Results One hundred five patients were enrolled from March 2000 through June 2003; 23% had SPT. Oropharynx (40%) and oral cavity (27%) were the predominant primary sites...
