Background: There is limited prospective data reporting the extent of treatment related toxicities associated with helical Intensity Modulated Radiotherapy (H-IMRT) for head and neck cancer (HNC). The study aim was to investigate severity, peak incidence and recovery patterns of dysphagia and related toxicities in patients undergoing H-IMRT +/- chemotherapy to examine when patients are experiencing symptoms requiring supportive clinical care. Methods: Prospective study of 212 patients undergoing H-IMRT. Dysphagia and associated acute toxicities were monitored weekly during treatment and at weeks 2, 4 and 12 post treatment using the CTCAE v4, Functional Oral Intake Score and National Dysphagia Diet Descriptors. Results: 75% experienced Grade 2-3 dysphagia. Over 70% had grade 2-3 dysguesia, xerostomia, and thick saliva, and >50% experienced grade 2-3 pharyngeal mucositis, oral mucositis, and nausea. 13% patients declined to NBM requiring complete enteral nutrition, 25% required enteral nutrition but maintained some form of oral intake. Symptoms peaked in final week of treatment, consistently improving thereafter, with the majority better than baseline by 12 weeks post-treatment. Concurrent chemotherapy at least doubles the odds of experiencing most symptoms excepting xerostomia, taste and fluid level. Conclusion: Despite advancements in radiation techniques, results confirm a high proportion of HNC patients experience dysphagia and related toxicities requiring supportive care during H-IMRT. Patients receiving H-IMRT alone experience a lower incidence of symptoms compared with those receiving concurrent chemotherapy. The data confirms the ongoing need for active on treatment monitoring with implications for the timing and intensity of patient support services. Crown Copyright (C) 2016 Published by Elsevier Ltd.
