Papers・Description | AIM:This study aimed to assess the utility and stability of intraoral stent during intensity-modulated radiation therapy (IMRT).BACKGROUND:The benefits of intraoral stents in radiotherapy are unclear.MATERIALS AND METHODS:We analyzed 386 setup errors in 12 patients who received IMRT for head and neck cancers without intraoral stents (intraoral stent [-]) and 183 setup errors in 6 patients who received IMRT with intraoral stents (intraoralstent [+]). All patients were matched according to the immobilization method (masks and boards). Setup errors were measured as the distance from the initial setup based on the marking on the skin and mask to the corrected position based on bone matching on cone beam computed tomography.RESULTS:The mean interfractional setup errors in the right-left, craniocaudal, anterior-posterior (AP), and three-dimensional (3D) directions were -0.33, 0.08, -0.25, and 2.75 mm in the intraoral stent (-) group and -0.37, 0.24, -0.63, and 2.42 mm in the intraoral stent (+) group, respectively (PCONCLUSION:Setup errors can be significantly reduced in the AP and 3D-directions by using intraoral stents. |
