Proton radiation therapy can be more cost effective or even cost saving, compared with photon radiation, with respect to the risk of growth hormone deficiency (GHD) in children with central nervous system (CNS) tumours undergoing hypothalamic radiation. This is the main finding of a US study ...
However, the main disadvantage of X radiotherapy is represented by the deposition of radiation also at the level of surrounding healthy tissues, leading to side effects. Although the ionizing radiation by proton beams (P) is currently more expensive and more difficult to produce, it has the ...
摘要: Compared with photon radiation (XRT), proton beam radiation therapy (PBRT) reduces dose to normal tissues, which may lead to better neurocognitive outcomes. We compared change in intelligence quotient (IQ) over time in pediatric patients with brain tumors treated with PBRT versus XRT....
Concurrent chemoradiotherapy administered with proton therapy might reduce toxicity and achieve comparable cancer control outcomes compared with conventional photon radiotherapy by reducing the radiation dose to normal tissues. Objective To assess whether proton therapy in the setting of concurrent ...
Intensity modulated radiation therapyPhotonsAuditory system modelsTissuesPurpose:The increased sparing of normal tissues in intensity modulated proton therapy (IMPT) in pediatric brain tumor treatments should translate into improved neurocognitive outcomes. Models were used to estimate the intelligence quotient ...
proton therapyThe goal of this study was to exam the efficacy of current DVH based clinical guidelines draw from photon experience for lung cancer radiation therapy on proton therapy. Comparison proton plans and IMRT plans were generated for 10 lung patients treated in our proton facility. A gE...

Additional models can easily be added including more OARs such as oral cavity, brainstem, or area postrema to predict acute and late radiation-induced toxicities, which may likely be reduced by proton therapy as well and could mean that the cost-effectiveness of protons will be underestimated. ...
However, little is known about the immunomodulatory efficacy of particle radiation, such as carbon ion radiotherapy (CIRT). With respect to carbon ion and proton irradiation, reports stating increased18,19 or comparable20 immune stimulating properties have been published. While the question whether the...
Comparison of supine or prone crawl photon or proton breast and regional lymph node radiation therapy including the internal mammary chainWe report on a dosimetrical study comparing supine (S) and prone-crawl (P) position for radiotherapy of whole breast (WB) and loco-regional lymph node regions...
