Advances in the management of recurrent or metastatic squamous cell carcinoma of the head and neck

Abstract

Most patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) undergo definitive therapy, yet locoregional recurrence and metastasis are common. Most patients ultimately require systemic treatment. Platinum/5-fluorouracil (5-FU) has been the standard of care for patients with good performance status (median survival, 6-8 months). Cetuximab, a monoclonal antibody against epidermal growth factor receptor (EGFR), significantly improved median survival in combination with platinum/5-FU compared with chemotherapy alone, establishing it as a new standard for patients with recurrent or metastatic disease. Cetuximab is also active in platinum-refractory disease. Ongoing trials are exploring other EGFR inhibitors as well as the use of biologic agents in combination (eg, cetuximab + bevacizumab). Predictive biomarkers may help personalize therapy for SCCHN, and it is unclear whether the favorable prognostic effect of p16 or human papillomavirus in locally advanced oropharyngeal cancer is relevant for advanced disease.
