Radiation therapy (RT) plays a fundamental role in the treatment of malignant and benign brain tumors. Current state-of-the-art photon- and proton-based RT combines more conformal dose distribution of target volumes and accurate dose delivery while limiting the adverse radiation effects. PubMed ...
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....
Lymphatic vessels were detected in the tumor-skin border of the control and P groups; however, they were also present in the core of the X tumors (Figure 4c), finding consistent with the over-expression of Oncogenesis (2017), 1 – 13 Proton versus photon radiation impact in squamous cell...
Such rapid dosing decays reduce radiation to nearby healthy tissues by a factor of 2–3. However, monitoring of treated patients for potential SPTs is a long-term proposition, and available research on SPT incidence by mode of MB treatment (proton vs. photon therapy) is currently lacking. ...
Importance Concurrent chemoradiotherapy is the standard-of-care curative treatment for many cancers but is associated with substantial morbidity. Concurrent chemoradiotherapy administered with proton therapy might reduce toxicity and achieve comparable cancer control outcomes compared with conventional photon radioth...
The second toxicity level should estimate whether the probability of radiation induced normal tissue toxicity for the patient is different between different treatment plans. The third cost-effectiveness level should evaluate if the extra costs for a certain increase in effectiveness does not exceed a ...

Using a proton beam treatment planning system, we compared the distribution of proton dose to x-ray dose in patients with HL treated with x-ray therapy at Mayo Clinic. We found that the integral dose of exposure radiation to the patient was reduced by at least 50% with the use of ...
