Current thoughts on the role of chemotherapy and radiation in advanced head and neck cancer

PURPOSE OF REVIEW: The management of advanced malignancies of the head and neck continues to be a challenging clinical problem. During the last three decades, the traditional treatments of surgery and/or radiation have not yielded significant improvements in survival in this patient population. In addition, surgery for advanced disease can create significant functional and cosmetic defects that adversely impact a patient's quality of life. Newer "organ preservation" approaches using chemotherapy and radiation are currently being studied in an attempt to improve survival while maintaining the functional integrity of the disease site. RECENT FINDINGS: Recent studies have demonstrated that for advanced head and neck squamous cell cancers, concurrent chemoradiation is superior to radiation alone for local tumor control and perhaps overall survival. With the exception of laryngeal cancer, phase III data comparing chemoradiation with surgery is lacking for most head and neck subsites. However, comparisons with historical controls suggest that chemoradiation strategies may offer improved outcomes when compared with more traditional treatment regimens. SUMMARY: This review emphasizes recent phase III trials that support the use of chemoradiation strategies in the treatment of advanced head and neck squamous cell cancers.
