This multicenter, open-label, uncontrolled phase II trial evaluates safety and efficacy of post-operative chemoradiation in combination with cetuximab in squamous cell carcinoma of the head and neck.

Advanced squamous cell carcinoma of the head and neck still has a poor prognosis and loco-regional recurrence frequently occurs. Efforts have been made to improve response rates and survival and different therapeutic regimens including concurrent chemo-radiotherapy or sequential chemo-radiotherapy have been developed. To further increase the outcome of patients with locally advanced SCCHN effective new treatments with minimal toxicities are needed. Molecular targeted agents, which do not demonstrate overlapping toxicities with commonly used chemotherapy agents, have therefore been investigated. The EGFR is widely expressed at high levels in SSCHN and is associated with poor prognosis. Cetuximab has already been investigated in combination with radiotherapy or chemotherapy in patients with head and neck cancer. The immunoradiotherapy was well tolerated with most of the side effects related to the high dose irradiation. The most common side effects are mucositis and dysphagia. Additionally, skin reactions appear sometimes more frequently in cetuximab administration. Grade 3 to 4 infusion reactions were observed in 3% of the patients treated with cetuximab. Based on the current promising results with RCT in patients with locally advanced head and neck cancer and clinical results with EGFR-antibodies plus RT, the present study was primarily designed to define the acute grade 3/4 toxicity. We expect to show effective results in reducing the risk of distant metastasis, with administration of an additional six month adjuvant cetuximab treatment, in patient with recurrent SCCHN.
