Hematology/Oncology Clinics of North America, 2019 Proton therapy is a form of external beam radiotherapy that has several advantages over conventional photon (x-ray) radiotherapy. Protons are useful in 2 scenarios that apply to a large proportion of cancer patients: lack of exit dose allows for delivery of a therapeutic radiation dose to tumors in challenging anatomic locations, and reduction in ...

British Journal of Cancer, 2005 Conventional radiation therapy directs photons (X-rays) and electrons at tumours with the intent of eradicating the neoplastic tissue while preserving adjacent normal tissue. Radiation-induced damage to healthy tissue and second malignancies are always a concern, however, when administering radiation.

Srpski arhiv za celokupno lekarstvo, 2021 Proton beam therapy (PBT) is an advanced type of radiotherapy that shows a dosimetric advantage over photon beam therapy and provides superior dose distribution. PBT may improve patient survival by improving the local disease control while reducing toxicity to normal organs, which may result in fewer treatment-related complications.

Treatment outcomes of passive scattering proton beam therapy for stage I non-small cell lung cancer
Radiation Oncology, 2021 Introduction To investigate the treatment outcomes of passive scattering proton beam therapy using stereotactic ablative radiotherapy (SABR) or hypofractionated radiation therapy (RT) for inoperable patients or those who refused surgery for stage I non ...

Physics in Medicine and Biology, 2015 The physics of proton therapy has advanced considerably since it was proposed in 1946. Today analytical equations and numerical simulation methods are available to predict and characterize many aspects of proton therapy. This article reviews the basic aspects of the physics of proton therapy, including proton interaction mechanisms, proton transport ...
