COMPARISON OF THE EFFECTIVENESS OF PROTON AND PHOTON THERAPY IN PATIENTS WITH BRAIN TUMORS

Сибирский онкологический журнал, 2021
Owing to the development of molecular genetics, the role of radiation therapy and chemotherapy in treatment of patients with glioma (WHO Grade I–IV) has become more understandable. The overall survival among glioma patients has increased.

Carbon Radiotheraphy For Head and Neck Cancer: Dosimetric Comparison with Photon Plans

Cumhuriyet Science Journal, 2022
Radiation therapy is one of the most widely used treatment methods for tumors. The therapeutic use of carbon ions is more advantageous than other radiotherapy techniquies especially photon-based irradiation due to its physical properties and ...

In vivo wireless photonic photodynamic therapy [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance The low penetration of light through tissue currently limits the therapeutic depth of photodynamic therapy (PDT) to less than a centimeter, even at near-infrared wavelengths. We report a wireless photonic approach to PDT in which miniaturized implantable devices deliver controlled doses of light by wireless powering ...

A Longitudinal Metagenomic Comparative Analysis of Oral Microbiome Shifts in Patients Receiving Proton Radiation Versus Photon Radiation for Head and Neck Cancer

Journal of Cancer and Allied Specialties, 2023
Introduction: Due to the radiation-sparing effects on salivary gland acini, changes in the composition of the oral microbiome may be a driver for improved outcomes in patients receiving proton radiation with potentially worse outcomes in patients ...

Proton versus photon radiation therapy: A clinical review

Frontiers in Oncology, 2023
While proton radiation therapy offers substantially better dose distribution characteristics than photon radiation therapy in certain clinical applications, data demonstrating a quantifiable clinical advantage is still needed for many treatment sites ...

Photon activation therapy and brachytherapy

Brachytherapy, 2009
In photon activation therapy (PAT), energy deposition at critical sites within a tumor can be increased by complexing the DNA with higher Z atoms, and provoking the emission of Auger electrons after inducing a photoelectric effect. This in vivo study evaluates the hypothesis using X-rays from palladium-103 seeds to excite the L-edge of platinum (Pt ...

Feasibility of Dose Escalation in Patients With Intracranial Pediatric Ependymoma

Frontiers in Oncology, 2019
Background and purpose: Pediatric ependymoma carries a dismal prognosis, mainly owing to local relapse within RT fields. The current prospective European approach is to increase the radiation dose with a sequential hypofractionated stereotactic boost. In
