OBJECTIVE: To determine the effects of 6\u00a0MV and 10\u00a0MV volumetric-modulated arc therapy (VMAT) photon beams on the target volume (TV) planning and critical organs in cases of cervical cancer. METHODS: Fifty patients with carcinoma of the cervix who underwent radiotherapy were selected. The transverse diameter (T) of the cross section of the upper edge of the sacroiliac joint on computerized tomography (CT) images of the patients was measured, and the mean value was calculated as 34\u00a0cm. All patients were divided into two groups: Group A (T &lt; 34\u00a0cm) and Group B (T &gt; 34\u00a0cm). The VMAT plans were generated using 6\u00a0MV and 10\u00a0MV plans separately. The prescription dose was 47.5\u00a0Gy, and the daily dose was 1.9\u00a0Gy. RESULTS: In Group A, the planning target volume (PTV) dose assessment parameters of 6\u00a0MV and 10\u00a0MV plans and their homogeneity and conformity indices were not statistically significantly different. A significant difference was observed between the 6\u00a0MV and 10\u00a0MV plans for the PTV dose assessment parameters and the homogeneity index of the plans for Group B. The monitor units (MUs) of the 10\u00a0MV plans were lower than in the 6\u00a0MV plans in both Groups A and B, and the difference was statistically significant. The assessment parameter V40 Gy of both the rectum and bladder in the 6\u00a0MV plans was smaller than the corresponding parameter in the 10\u00a0MV plans in Group A; in Group B, the assessment parameter V50 Gy of the rectum in the 10\u00a0MV plans was smaller than in the 6\u00a0MV plans. CONCLUSION: When T &lt; 34\u00a0cm, 6\u00a0MV energy is more suitable for the external irradiation of cervical cancer. When T &gt; 34\u00a0cm, 10\u00a0MV energy is more suitable for cervical cancer radiotherapy. Therefore, 10\u00a0MV should be considered for patients with a large abdominal size.<\/jats:p>","DOI":"10.3233\/thc-213617","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T12:26:14Z","timestamp":1653999974000},"page":"1515-1523","source":"Crossref","is-referenced-by-count":4,"title":["Evaluating the influence of 6MV and 10MV photon beams on cervical cancer volumetric-modulated arc therapy plans"],"prefix":"10.1177","volume":"30","author":[{"given":"Dong-Cheng","family":"He","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi-Jian","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-Ye","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Hong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ting-Ting","family":"Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-Hua","family":"Han","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"2","key":"10.3233\/THC-213617_ref1","doi-asserted-by":"publisher","first-page":"87","DOI":"10.3322\/caac.21262","article-title":"Global cancer statistics","volume":"65","author":"Torre","year":"2015","journal-title":"2012.
