Intensity-modulated radiation therapy plans delivering 54 Gy necessarily exposed the right kidney to a V18 of 98% and the liver to a V30 of 55%. Proton therapy plans significantly reduced the right kidney V18 to 32% and the liver V30 to 28%. In light of this, the proton plan was ...
Note: A and B represent the target area and field distribution for intensity-modulated radiation therapy (IMRT) with X-rays, respectively; C and D represent the target area and field distribution for fixed-angle proton therapy, respectively Full size image Table 2 Radiation Therapy Doses and ...
The book is divided into two parts: Part I deals with the relevant physics and planning algorithms of protons (H Breuer) and Part II with the radiobiology, radiopathology and clinical outcomes of proton therapy and a comparison of proton therapy versus photon therapy (BJ Smit). Protons can be...
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....
To assess and compare secondary cancer risk resulting from intensity-modulated radiotherapy (IMRT) and proton therapy in patients with prostate and head-and-neck cancer. Intensity-modulated radiotherapy and proton therapy in the scattering mode were planned for 5 prostate caner patients and 5 head-and...
[4]compared the proton therapy versus photon therapy in the form of volumetric modulated radiation therapy (VMAT) for high-risk prostate cancer, and the study showed comparable target doses, but proton therapy was better at sparing the rectum and bladder, especially in the low- and medium-dose...
of protons is still a work-in-progress. “We need to systematically evaluate the clinical potential and define it through rigorous science – quantifying the benefits versus investment,” argued Metz. “After all, substantial resource and infrastructure are needed to support a proton ther...
