Is There a New Role for Induction Chemotherapy in the Treatment of Head and Neck Cancer?
11/16/2004 Arlene A. Forastiere Journal of the National Cancer Institute, Vol. 96, No. 22, 1647-1649, November 17, 2004 Editorial The majority of deaths from locally advanced head and neck cancer are due to complications of uncontrolled locoregional disease, and this pattern of failure must be altered to improve patient survival. Over the past 25 years, thousands of patients with head and neck cancer have been enrolled in clinical trials to test whether the addition of platinum-based chemotherapy to local treatment modalities of surgery and radiotherapy improves overall survival. These studies have taken two approaches. In the first approach, several cycles of neoadjuvant or induction chemotherapy (most commonly cisplatin and infusional 5-fluorouracil) precede definitive locoregional therapy (i.e., surgery). The second approach is chemoradiotherapy, the concurrent administration of radiotherapy and chemotherapy. Of the two approaches, only chemoradiotherapy has succeeded in changing outcomes. Numerous phase III trials that have compared radiotherapy alone to chemoradiotherapy have shown that the latter statistically significantly improved locoregional control and that the magnitude of improvement is sufficient to have an impact on overall survival (1–5). As a consequence of these findings, over the last decade, chemoradiotherapy has become the standard of care for the management of unresectable head and neck cancers and nasopharyngeal cancers (i.e., stage T3, stage T4, or lymph node–positive cancers) and for the nonoperative management of locally advanced oropharyngeal cancers. By contrast, only two (6,7) of more than 30 randomized trials have demonstrated that induction chemotherapy confers a survival advantage. In addition, induction chemotherapy has [...]
