Volumetric Modulated Arc Therapy in Oropharyngeal Carcinoma

Treatment: Outcome and Toxicity of Volumetric Modulated Arc Therapy in Oropharyngeal Carcinoma:

Background/Aim: Radiotherapy is a common approach for treating squamous cell carcinoma (SCC) of the oropharynx. We aimed to analyze toxicity and outcome of patients affected by oropharyngeal SCC treated with volumetric modulated arc therapy (VMAT). Patients and Methods: Fifty-four patients presenting advanced orophayngeal carcinoma who were treated with radical radiotherapy were analyzed. All patients were treated with VMAT-RapidArc, with simultaneous integrated boost in 33 fractions for a dose of 69.96 Gy to the high-risk, and of 54.45 Gy to the low-risk volume. Results: Median follow-up was 23 months. In eight cases, locoregional relapse was observed (median time to relapse=10.7 months). Four among eight local recurrences appeared in the high-dose target volume. The 1- and 2-year actuarial disease-free survival rates were 88% and 80%, respectively. The 1- and 2-year actuarial overall survival rates were 94% and 87%, respectively. Conclusion: VMAT for oropharyngeal SCC treatment is effective and safe, with interesting rates of control of disease and survival.
