Proton Beam Radiotherapy for Medulloblastoma and Pineoblastoma

There are two types of external radiation treatments (proton beam and photon beam). As part of the participant's treatment, they will receive radiation to the entire central nervous syste...

Hypofractionated Proton Beam Radiation Therapy, Paclitaxel, and Carboplatin in Treating Patients With Stage II-III Non-Small Cell Lung Cancer

This phase I trial studies the side effects and best dose of hypofractionated proton beam radiation therapy when given together with paclitaxel and carboplatin in treating patients with st...

Proton Beam Radiation Therapy in Treating Patients With Low Grade Gliomas

RATIONALE: Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damag...

Proton Beam Radiation Therapy for Early Stage Adenocarcinoma of the Prostate

The primary purpose of this study is to determine if high doses of radiation using proton beam can be given safely with low and acceptable side effects. This study will also gather data t...

Proton Beam Irradiation for the Treatment of Unresectable Hepatocellular Cancer or Hepatic Metastases

The main purpose of this study is to determine if high doses of radiation using proton beam can be given safely with low and acceptable side effects. We will also gather information to de...

Proton beam irradiation inhibits the migration of melanoma cells.

In recent years experimental data have indicated that low-energy proton beam radiation might induce a difference in cellular migration in comparison to photons. We therefore set out to compare the eff...

RADIATION PROTECTION MEASUREMENTS WITH THE VARIANCE-COVARIANCE METHOD IN THE STRAY RADIATION FIELDS FROM PHOTON AND PROTON THERAPY FACILITIES.

The microdosimetric variance-covariance method was used to study the stray radiation fields from the photon therapy facility at the Technical University of Denmark and the scanned proton therapy beam ...

CHARACTERIZATION OF 27 MEV PROTON BEAM GENERATED BY TOP-IMPLART LINEAR ACCELERATOR.

The first proton linear accelerator for tumor therapy based on an actively scanned beam up to the energy of 150 MeV, is under development and construction by ENEA-Frascati, ISS and IFO, under the Ital...

Feasibility of Pencil Beam Scanned Intensity Modulated Proton Therapy in Breath-hold for Locally Advanced Non-Small Cell Lung Cancer.

We evaluated the feasibility of treating patients with locally advanced non-small cell lung cancer (NSCLC) with pencil beam scanned intensity modulated proton therapy (IMPT) in breath-hold.

DOSIMETRIC CHARACTERIZATION OF COLLIMATORS FOR SPATIALLY FRACTIONATED PROTON THERAPY OF THE EYE.

The aim of these studies was to investigate depth dose distribution of a 60 MeV proton beam formed by a set of dedicated mesh-formed collimators. The set of mini-beams formed by the mesh is scattered ...

Medical and Biotech [MESH] Definitions

An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1189)

An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

The use of an external beam of PROTONS as radiotherapy.

Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.

The use of pre-treatment imaging modalities to position the patient, delineate the target, and align the beam of radiation to achieve optimal accuracy and reduce radiation damage to surrounding non-target tissues.
