PurposeTo determine the risk of contralateral nodal failure following ipsilateral radiotherapy in a series of patients with node-positive tonsillar squamous cell carcinoma.MethodsRetrospective review was used to identify 34 patients with well-lateralized node-positive tonsillar squamous cell carcinoma treated with definitive or adjuvant radiation to the primary site and ipsilateral neck between 2005 and 2015. Contralateral nodal failure, locoregional recurrence, distant metastasis, and overall survival were calculated using actuarial and/or cumulative incidence statistics.ResultsAt last follow-up, contralateral nodal failure was only observed in 1 patient (3%) with N1 disease. At median follow-up of 34 months for surviving patients, the 3-year overall survival probability was 87%, and the 3 year cumulative incidences of locoregional failure and distant metastasis were 6.5% and 7.2%, respectively. No disease-free patient was permanently gastrostomy-dependent.ConclusionIpsilateral radiation treatment with IMRT is effective in node-positive patients with well-lateralized tonsillar cancer, resulting in a low risk of contralateral regional recurrence, even in patients with N2b disease.
