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 ...
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 ...
However, the proton and IMRT normal lung gEUD(a) curves crossed for 8 patients within the tested range of "a", which means there was a possibility that proton plan would be worse than IMRT plan for lung sparing. A concept of deficiency index (DI) was introduced to quantify the ...

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. ...
While for photon radiation hypofractionation has been reported to induce enhanced immunomodulatory effects, little is known about the immunomodulatory potential of carbon ion radiotherapy (CIRT). We thus compared the radio-immunogenic effects of photon a
The ligands were injected intravenously at a dosage of 30 mu mol.kg(-1) and the animals killed 24 h later. The results show that none of the chelators tested was efficient in removing significant amounts of the radionuclide from the body. In order to understand why these chelators were ...
Radiation Physics John H. Hubbell, in Encyclopedia of Physical Science and Technology (Third Edition), 2003 IV.A.2 Photons (e.g., X Rays, g Rays, Bremsstrahlung) Photons are electromagnetic wave-trains, differing from visible light only by having a shorter wavelength and a higher energy, wit...
