TOMO and s-IMRT were established for 10 patients with maxillary sinus cancer. The prescription (66 Gy, 30 fractions) was used to cover the planning target volume (PTV) with a 95% isodose line. Each plan was independently optimized using the CORVUS planning system and Tomotherapy Hi-Art system. The treatment plans were compared using dose volume histogram (DVH), a dose homogeneity index (DHI) of the PTV, and equivalent uniform dose (EUD) and DVH of organs at risk (OARs). The TOMO plans demonstrated better dose homogeneity compared to the s-IMRT plans. The average V95% of the TOMO plans was similar to that of the s-IMRT (92.92% vs. 95.07%, respectively), but the average V107% was 0% for TOMO compared with 18.74% for s-IMRT. The average maximum dose reduction was 7 Gy, and DHI increased by 8% for PTV1 in TOMO compared with s-IMRT (79 Gy vs. 71 Gy and, 89% vs. 97%, respectively). The average EUD reduction for the optic nerve was 17%. In summary, planning with TOMO was superior to s-IMRT planning with respect to dose homogeneity within the PTV and sparing of the optic nerve.<\/jats:p>","DOI":"10.1177\/153303460900800402","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:55:00Z","timestamp":1412348100000},"page":"257-263","source":"Crossref","is-referenced-by-count":8,"title":["A Comparison of Treatment Plans using Linac-Based Intensity-Modulated Radiation Therapy and Helical Tomotherapy for Maxillary Sinus Carcinoma"],"prefix":"10.1177","volume":"8","author":[{"given":"Songyih","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ik Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong Bae","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woong Sub","family":"Koom","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Byeong Chul","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang Geol","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gwi Eon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ki Chang","family":"Keum","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Yonsei University Health System, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,8,1]]},"reference":[{"key":"bibr1-153303460900800402","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0709(99)90078-9"},{"key":"bibr2-153303460900800402","doi-asserted-by":"publisher","DOI":"10.1016\/0167-8140(91)90037-H"},{"key":"bibr3-153303460900800402","first-page":"118","volume":"25","author":"Kim J.
