In Regard to Ward et al

To the Editor: We read the study by Ward et al (1) with great interest and would like to congratulate the authors for their multi-institutional effort on this critically important subject in the era of intensity-modulated radiation therapy. The investigators of the Multi-Institution Reirradiation collaborative analyzed 412 patients with recurrent or second primary (RSP) head and neck cancers who had received at least 40 Gy during the initial radiation therapy and were treated with further ≥40 Gy reirradiation by utilizing the intensity-modulated radiation therapy technique.
