Background: This retrospective study evaluates efficacy and tolerability of high-dose hypofractionated radiotherapy (RT) in patients with head and neck cancer.
Methods: All patients with head and neck cancer treated between September 2003 and September 2013 with 12 × 4 Gy RT were included. Two and 3D-RT or intensity-modulated radiotherapy (IMRT) were used. Overall survival (OS), tumor response, and palliative effect were evaluated.
Results: Palliative effect occurred in 63% of 81 included patients, lasted a median of 4.6 months, and was correlated with tumor response (p = .006). Median OS was 7.2 months. Confluent mucositis occurred more often in patients treated with 2D/3D-RT than IMRT (26% vs 44%; p = .04) and lasted for a median of 2 weeks.
Conclusion: High-dose hypofractionated RT resulted in meaningful palliation in 63%, lasting for almost 5 months. IMRT should be the technique of choice, as it results in less high-grade toxicity. The 12 × 4 schedule should be opted for patients with reasonable functional capacities and a life expectancy of >6 months. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1264-E1270, 2016.
