BACKGROUND: The aim of this study was to evaluate the prognostic factors and treatment outcomes of advanced maxillary gingival squamous cell carcinoma (SCC) treated with intra-arterial infusion chemotherapy concurrent with radiotherapy. METHODS: A total of 46 patients were reviewed retrospectively in this study. The treatment schedule comprised intra-arterial chemotherapy (total, 60 mg/m2 docetaxel and 150 mg/m2 cisplatin) and three-dimensional computed tomography based, daily conventional radiotherapy (total, 60 Gy/30 fr) for 6 weeks. RESULTS: The median follow-up period was 40 months (range, 3-110 months). The 3-year overall survival and locoregional control rates for all patients were 64.3% and 84.3%, respectively. The OS rate of the patients with N0-1 was significantly higher than that of the patients with N ≥ 2 (P < .05). No grade 5 toxicities were observed. CONCLUSIONS: Intra-arterial infusion chemotherapy concurrent with radiotherapy was effective for advanced maxillary gingival SCC.
