With a median follow‐up of 28 months (range, 6–85 months), the 3‐year actuarial rates of overall survival, locoregional control, and distant metastasis‐free survival were 83%, 90%, and 88%, respectively.</p> </sec> <sec id="hed23209-sec-0004" sec-type="section"> <title>Conclusion</title> <p>These findings attest to the exquisite radiosensitivity of HPV‐positive head and neck cancer. The clinical outcomes observed from this selected series compare favorably with historical controls treated by more intensive chemoradiotherapy strategies. © 2013 Wiley Periodicals, Inc. <italic>Head Neck</italic>, <bold>35</bold>: 1652–1656, 2013</p> </sec> </abstract>
