Long-term disease control in a metastatic squamous cell carcinoma of the oral cavity treated with maintenance metronomic capecitabine

摘要

Recurrent or metastatic disease occurs in two-thirds of head and neck squamous cell carcinomas and it is associated with poor prognosis. Systemic treatment with platinum-based chemotherapy in combination with the epidermal growth factor receptor-targeting monoclonal antibody cetuximab represents a preferred option for these patients. Upon the achievement of tumor response by combined treatment, maintenance with single-agent cetuximab is usually administered with the aim of prolonging disease control at the price of reasonable toxicity. Although rarely, however, cetuximab needs to be discontinued in the absence of disease progression because of intolerable side effects. Here we describe the case of a 66-year-old man with a metastatic cancer of oral cavity, who had to discontinue maintenance cetuximab and who achieved prolonged disease control with metronomic capecitabine. We suggest that capecitabine could be an effective and safe maintenance option in case of cetuximab intolerance.
