Background: The purpose of this study was to evaluate the efficacy and toxicities of proton beam therapy combined with intra-arterial infusion chemotherapy via superficial temporal and occipital arteries for recurrent oral cavity squamous cell carcinoma (SCC).
Methods: Between October 2009 and June 2013, 46 patients with recurrent oral cavity SCC were treated by proton beam therapy combined with intra-arterial infusion chemotherapy of cisplatin (CDDP) and docetaxel. Treatment consisted of proton beam therapy (28.6-74.8 GyE in 13-34 fractions) and intra-arterial infusion chemotherapy (CDDP, 30-50 mg/body/week; docetaxel, 5-25 mg/body/week).
Results: One-year and 2-year overall survival (OS) rates were 65% and 46%, respectively. One-year and 2-year local control rates were 81% and 70%, respectively.
Conclusion: These findings suggest that proton beam therapy combined with intra-arterial infusion chemotherapy could be applied effectively and safely for patients with recurrent oral cavity SCC. © 2016 Wiley Periodicals, Inc. Head Neck 38:1145-1151, 2016.
