Retrograde intra-arterial chemotherapy and daily concurrent proton beam therapy for recurrent oral cavity squamous cell carcinoma: Analysis of therapeutic results in 46 cases

Abstract

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, 2016
