RESUMEN
OBJECTIVES: To assess the effect on progression-free and overall survival from the addition of cetuximab to paclitaxel-based chemoradiation for patients with squamous cell head and neck cancer from Brown University Oncology Group studies. METHODS: BrUOG HN-204 patients with stage III or IV locally advanced squamous cell cancer of the head and neck without distant organ metastases received 4 weeks of induction cetuximab followed by weekly cetuximab, paclitaxel, carboplatin, and concurrent radiation. Recurrence and survival data were compared with previous Brown University studies utilizing the same paclitaxel-based chemoradiation with and without induction chemotherapy. RESULTS: The progression-free survival and overall survival at 3 years for all 37 patients initiating chemoradiation was 54% and 57%, respectively. All surviving patients were followed for at least 3 years and the median follow-up is 4.4 years. Of 14 patients who recurred within 3 years, 7 patients recurred locally only, 5 had a systemic recurrence, and 2 recurred both locally and systemically. CONCLUSIONS: The addition of cetuximab to paclitaxel, carboplatin, and radiation achieves overall survival that is virtually identical to prior Brown University Oncology Group studies of paclitaxel-based chemoradiation without cetuximab. Improvements in locoregional control are needed despite the use of 3 agents to enhance the effects of radiation.

OBJECTIVE: To determine the feasibility and toxicity of the addition of cetuximab to paclitaxel, carboplatin, and concurrent radiation for patients with head and neck cancer. MATERIALS AND METHODS: Patients with stage III or IV locally advanced squamous cell cancer of the head and neck, without distant organ metastases, were eligible. Patients received 4 weeks of induction cetuximab followed by weekly cetuximab, paclitaxel, carboplatin, and concurrent radiation. RESULTS: Thirty-two patients were assessable for chemoradiation toxicities. Grade 3 and grade 4 mucositis occurred in 53% and 16% of patients, respectively. Grade 3 and grade 4 radiation dermatitis occurred in 44% and 9% of patients, respectively. Grade 3/4 radiation dermatitis was associated with the use of intensity modulated radiation therapy (64% vs.14%, respectively, P < 0.0001). Grade 3 and grade 4 cetuximab associated acneiform rash developed in 6% and 3% of patients. Overall 21 patients (66%) had any grade 3 toxicity and 10 patients (31%) had any grade 4 toxicity. The percentages of the intended total dose delivered of carboplatin, cetuximab, paclitaxel, and radiation were 86%, 89%, 89%, and 96%, respectively. CONCLUSION: Cetuximab, when combined with paclitaxel, carboplatin and intensity modulated radiation therapy, increases dermatologic toxicity but does not increase mucosal toxicity as compared with previous Brown University Oncology Group studies of paclitaxel, carboplatin, and conventional radiation for patients with head and neck cancer.
