Background The primary purpose of this study was to review the efficacy of unilateral treatment of lateralized tonsil primaries, in particular whether laterality of the primary is a more powerful determinant of contralateral neck failure than advanced ipsilateral nodal classification. Methods A retrospective study of all patients with tonsillar cancer treated with curative intent between January 1990 and December 2002 was performed. Results There were 167 patients, 76% men, median age 58 years, 86% current or ex‐smokers. The majority of patients (58%) had stage IV disease. Five‐year local, nodal, locoregional, and distant failure rates were 14%, 4%, 18%, and 8%, respectively. Of the 58 patients treated unilaterally, 33% had N2a, N2b, or N3 nodal disease. There were no contralateral nodal failures in the unilaterally treated group. Conclusion These results support the potential use of unilateral radiation therapy (RT) for lateralized tonsil primaries even with advanced ipsilateral nodal disease. © 2013 Wiley Periodicals, Inc.
