PurposeThe purpose of this study was to compare the survival of patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) undergoing concurrent chemoradiotherapy (CRT) alone with that of patients undergoing induction chemotherapy (IC) using docetaxel, cisplatin, and 5-fluorouracil (TPF) followed by CRT.Materials And MethodsA search of the PubMed, EMBASE, and Cochrane Library databases was performed in April 2015 and abstracts from the American Society of Clinical Oncology meetings (2008-2014) were reviewed. Summaries of the results were pooled using a fixed-effect model, and the risk of bias was evaluated using the Cochrane tool.ResultsA total of six relevant trials comprising 1,280 patients were identified. There was no statistically significant overall survival (OS) advantage for TPF prior to CRT (TPF/CRT) over CRT alone (hazard ratio [HR] 0.92; 95% confidence interval [CI], 0.79 to 1.09; p=0.339). Progression-free survival (PFS) was significantly longer in the TPF/CRT arms (HR, 0.82; 95% CI, 0.70 to 0.95; p=0.009). Patients with non-oropharyngeal LA-HNSCC obtained the greatest OS and PFS benefits from TPF (HR, 0.68; 95% CI, 0.47 to 0.99; p=0.043 and HR, 0.67; 95% CI, 0.48 to 0.94; p=0.022, respectively). The complete response rate was significantly increased (risk ratio [RR], 1.34; 95% CI, 1.14 to 1.56; p < 0.001), and the distant metastasis rate tended to decrease (RR, 0.65; 95% CI, 0.40 to 1.04; p=0.071) in the TPF/CRT arms.ConclusionIC with TPF followed by CRT is not superior to CRT alone for OS. However, PFS and the complete response rate were significantly improved in the TPF/CRT arms. TPF/CRT for patients with nonoropharyngeal LA-HNSCC provided clear survival advantages.
