The role of chemotherapy in locally advanced head and neck squamous cell carcinoma.
The role of chemotherapy in multimodality treatment for locally advanced head and neck squamous cell carcinoma, although firmly established, presents several unresolved issues. Concomitant platinum-based chemoradiation (CRT) is a standard treatment for unresectable, resectable but nonsurgically treated, and postoperative high-risk patients with locally advanced head and neck squamous cell carcinoma. However, no clear conclusion can be drawn regarding the optimal platinum compound or combinations to use, the type of schedule, and number of cycles (ie, platinum total dose) to be delivered. Cetuximab administered concomitantly with radiotherapy has not been directly compared with CRT but offers a potential different approach using a noncytotoxic systemic agent. In the organ preservation setting, CRT, although yielding a superior 5-year larynx preservation rate, showed similar outcomes to induction chemotherapy (IC) followed by radiation in terms of 5-year laryngectomy-free survival and overall survival, with a higher incidence of grade 3-4 mucositis. The role of IC in nonorgan preservation programs has not yet been established. Phase III trials comparing concomitant CRT versus IC followed by CRT are ongoing with results anticipated in the near future.
