Induction Chemotherapy for Head and Neck Cancer: Recent Data

Abstract

Abstract The addition of chemotherapy to radiotherapy in the treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN) patients improves survival. Meta-analyses of randomized trials have indicated that the benefit of this approach is associated with the timing of chemotherapy administration. It has been demonstrated that the greatest survival benefit over locoregional treatment alone is seen with the concurrent administration of chemotherapy and radiotherapy. However, sequential chemotherapy administration, in the form of induction chemotherapy followed by radiotherapy or concurrent chemoradiotherapy, has been successful as a strategy for organ function preservation in patients with potentially resectable SCCHN. In addition, a meta-analysis of trials using platinum and 5-fluorouracil (PF)-containing induction regimens demonstrated a significant survival benefit for this approach over locoregional treatment alone in locally advanced disease. In recent years, the introduction of the taxanes into induction chemotherapy has provided physicians with more active regimens. The triplet combination induction regimen of docetaxel, cisplatin, and 5-fluorouracil has been shown to be more effective in prolonging survival than the doublet PF. Current trials are testing whether the addition of induction chemotherapy to standard concomitant chemoradiotherapy is superior to concomitant chemoradiotherapy alone.
