Abstract
BACKGROUND: To conduct a comprehensive review whether chemotherapy to radiotherapy after surgical resection could improve the loco regional control and survival compared with postoperative radiotherapy alone. METHODS: A comprehensive search of PubMed for relevant studies comparing patients with advanced squamous cell carcinoma of the head and neck undergoing chemoradiotherapy or radiotherapy alone after resection was conducted. RESULTS: The meta-analysis demonstrated significant benefits from adding chemotherapy to radiotherapy in local-regional control, disease-free survival and overall survival (p < 0.00001). The adverse effects include hematological and non-hematological toxicities. Although the acute and late toxicities occurred more frequently and severely in chemoradiation combined treatment, there was no significant difference compared with radiotherapy alone, but the estimated pooled RR of mucositis or dysphagia was 1.69 (p < 0.00001) in favor of radiotherapy regimens. CONCLUSIONS: Postoperative chemotherapy adding to radiotherapy is superior to radiotherapy alone. Patients with chemoradiotherapy after surgical resection can achieve the higher LRC, longer DFS and OS.
