ABSTRACT

The management of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) is highly complex. Data from recent clinical trials have altered the treatment landscape by refining the use of existing therapies, such as radiation therapy and chemotherapy, and providing new treatment options, such as cetuximab. Selecting the most appropriate treatment for an individual patient requires a multidisciplinary approach and careful assessment of the relative advantages and disadvantages of each treatment approach. Surgery is highly effective but can have debilitating long-term consequences. Chemoradiation and altered fractionation radiation therapy are more effective than conventional radiation therapy, but also more toxic; as a consequence of toxicity, suboptimal delivery of radiation may diminish, in practice, the efficacy observed in clinical trials of these strategies. Cetuximab plus radiation therapy is more effective than radiation alone and does not substantially increase radiation-related toxicity, or affect the delivery of planned radiotherapy. However, whether cetuximab plus radiation therapy is similar in efficacy to chemoradiation is unknown at this time. Ideally, multidisciplinary teams weigh all these factors when making individual treatment decisions. Data from current trials will help further optimize multimodality treatment for LA-SCCHN.
