Protons will replace photons for radical dose therapy |
“Because of the dose distributional advantages of proton beams, my judgment is that protons will replace photons for radical dose therapy within the next 2-3 decades. Radiation oncologists, referring physicians, and society at large will continue to become more knowledgeable
about improved methods. It is certain that they will demand the best treatment. Furthermore, we and the public will be less tolerant of treatment-related morbidity rates, especially in non-target tissues. The substantial number of proton treatment centers being actively planned or under construction shows that we are moving in that direction.”

“The importance of dose sparing to healthy tissue in preventing side effects should not be underappreciated. The superior dose limiting properties of protons vs xray are depicted in the comparative distributions for pediatric meduloblastoma.” 1
"Proton techniques were shown to be superior to all photon approaches for the irradiation of small brain lesions in terms of target dose uniformity and conformity and in terms of sparing organs at risk."2
“In a model study of tonsil cancers, it is shown that a higher tumour dose can be administered with protons than with photons, with presumed superior local control and survival, at the same time as a lower dose is delivered to the spinal cord, mandible and contralateral parotide glands, resulting in improved quality of life and less risk of complications.”3
“Proton beam therapy offers a clear advantage over both conventional external beam radiation therapy and intensity modulated radiation therapy for treatment of children with brain tumors”4
