A Multidisciplinary Approach to Implement Image-Guided Craniospinal Irradiation
We report our experience in developing and refining CSI planning and treatment parameters, using a 3-isocenter image-guided intensity-modulated radiation therapy (IG-IMRT) technique.
Radiation therapy plays a critical role in the treatment of esophageal cancer (EC), especially for locally advanced EC . Historically, three-dimensional conformal radiotherapy (3DCRT) has been the most widely used radiation technique for EC. Based on inverse planning algorithm and complex modulated beams, IMRT can provide improved target coverage and better sparing of organs at risk (OARs) . Therefore, as an advanced conformal radiation modality, intensity-modulated radiotherapy (IMRT) has been increasingly adopted worldwide over the past decade [3,4].

ConclusionAfter great improvements in rectal cancer treatment, late gastrointestinal toxicity after radiotherapy is experienced less frequent and less severe; however, it remains a great concern associated with worse quality of life.
The use of a specific treatment technique in radiation therapy is mainly motivated by the achievable dose conformity to the target and the overall integral dose. Proton therapy offers a highly conformal and comprehensive treatment option with a lower integral dose (reduced low-dose bath) to organs at risk (OARs). Consequently, given the proximity of cardiopulmonary structures, proton therapy has been discussed as a treatment alternative for breast cancer patients [1 –3]. Treatment planning studies, comparing 3DCRT, IMRT, and proton therapy when irradiating the breast and regional nodes showed advantages of using prot...

Abstract PURPOSE: Using a 200 Head and Neck cancer (HNC) patient cohort, we employ patient similarity based on tumor location, volume, and proximity to organs at risk to predict radiation-associated dysphagia (RAD) in a new patient receiving intensity modulated radiation therapy (IMRT). MATERIAL AND METHODS: All patients were treated using curative-intent IMRT. Anatomical features were extracted from contrast-enhanced tomography scans acquired pre-treatment. Patient similarity was computed using a topological similarity measure, which allowed for the prediction of normal tissues' mean doses. We performed feat...
