The evolution of three-dimensional conformal radiation therapy and intensity-modulated radiation therapy (IMRT) have allowed physicians to spare surrounding normal organs and reduce adverse effects. The introduction of proton beam technology and its physical advantage of depositing its energy in tissue at...
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....

Photon and proton therapy planning comparison for malignant glioma based on CT, FDG-PET, DTI-MRI and fiber tracking Purpose. The purpose of this study was to compare treatment plans generated using fixed beam Intensity Modulated photon Radiation Therapy (IMRT), inversely... Per,Munck,af,... -...
Effect of photon vs. proton radiation on tumor cell viability In the UPS cell culture group, no significant differences in cell viability were visible between photon and proton irradiation after four days (supplementary Fig. 5A). Eight days after irradiation, there was a slightly higher cell-killi...
Radiobiological risk estimates of adverse events and secondary cancer for proton and photon radiation therapy of pediatric medulloblastoma. Introduction. The aim of this model study was to estimate and compare the risk of radiation-induced adverse late effects in pediatric patients with medullo... Bro...
For instance, the first comparison of IMRT versus IMPT among oropharyngeal cancer patients treated with chemo-radiation in the MD-Anderson Cancer centre [46] showed a significant decrease of required tube feeding during the course of radiation when IMPT was used. In this regard, direct measurement...
radiationsthat basically use the same mechanisms to kill tumor cells, i.e., through a transfer of energy (from the photon or proton to the cell) that results in damage to the cellular DNA and subsequent cell death. In general, the radiation tolerance of normal tissues and organs is ...
