Head and neck cancer: guidelines for chemotherapy.
Head and neck cancer is estimated to be one of the most prevalent cancers in the world. This tumour type accounts for 5% of all new cancer cases in the US and Europe each year. Patients with locally recurrent or metastatic squamous cell carcinoma of the head and neck have a poor prognosis, with a median duration of survival between 4 and 6 months. During the past few years, screening for potentially active new compounds, new associations and new modalities of chemotherapy administration have had some degree of success. Clinical investigations have also focused on the addition of chemotherapy to locoregional treatment for patients with locally advanced disease. Induction chemotherapy or concomitant chemo- and radiation therapy can result in high response rates, and reduced incidence of distant metastases. However, there is no clear demonstration of any benefit from the addition of chemotherapy to locoregional therapy on overall survival in patients with resectable disease. In patients with resectable laryngeal or hypopharyngeal cancer, chemotherapy combined with radiotherapy can be considered as a standard treatment option for larynx preservation, keeping total laryngectomy reserved for salvage therapy. In patients with unresectable head and neck cancer, simultaneous chemoradiotherapy has been shown to improve locoregional control and survival, at the cost of greater toxicity. Outside clinical trials, this approach can also be considered as a standard therapy for unresectable disease.
