CONTEXT There has been rapid adoption of newer radiation treatments such as intensity-modulated radiation therapy (IMRT) and proton therapy despite greater cost and limited demonstrated benefit compared with previous technologies. OBJECTIVE To determine the comparative morbidity and disease control of IMRT, proton therapy, and conformal radiation therapy for primary prostate cancer treatment....

Proton therapy represents the most advanced form of radiotherapy currently available. Hepatocellular carcinoma (HCC) has been extensively treated with proton therapy since 1983 with encouraging results in terms of effectiveness and safety, as reported in recent research articles, systematic reviews and meta-analyses. In this report, we summarized for the first time the results of proton therapy...

Particle beam therapy has been rapidly developed in these several decades. Proton and carbon ion beams are most frequently used in particle beam therapy. Proton and carbon ion beam radiotherapy have physical and biological advantage to the conventional photon radiotherapy. Cancers of the skull base, nasal cavity, and paranasal sinus are rare; however these diseases can receive the benefits of p...

BACKGROUND In this prospective study, the authors evaluated potential treatment toxicity and progression-free survival in patients with low-grade glioma who received treatment with proton radiation therapy. METHODS Twenty patients with World Health Organization grade 2 glioma who were eligible for radiation therapy were enrolled in a prospective, single-arm trial of proton therapy. The patien...

Three patients with hepatocellular carcinoma (HCC) and inferior vena cava tumor thrombus (IVCTT) were treated using proton beam therapy at the University of Tsukuba, Japan. A total dose of 50-70 Gy in 10-35 fractions was given to the primary tumor and IVCTT. All the patients survived for more than 1 year from the beginning of proton beam therapy (13-55 months) and no treatment-related toxicity ...

Desmoid tumors are benign mesenchymal tumors with a strong tendency for local recurrence after surgery. Radiotherapy improves local control following incomplete resection, but nearby organs at risk may limit the dose to the target volume. The patient in this report presented with a recurrent desmoid tumor of the right flank and underwent surgery with microscopically positive margins. Particular...

BACKGROUND Craniospinal irradiation (CSI) is the standard radiation therapy treatment for medulloblastoma. Conventional CSI photon therapy (Photon-CSI) delivers significant dose to surrounding normal tissue (NT). Research into pediatric CSI with proton therapy (Proton-CSI) has increased, with the aim of exploiting the potential to reduce NT dose and associated post-treatment complications. This...

demonstrate the sensitivity and specificity of claims-based algorithms to detect important radiotherapy outcomes and exposures across disease sites. Second, equipment manufacturers should develop unique technology identifiers for radiotherapy devices and image guidance that would facilitate identification in registries or possibly claims data. For example, the proposed National Radiation Oncolo...

In proton therapy, the dose from secondary neutrons to patient can contribute side effects and creation of cancer. A simple fast detection system distinguish between protons both in pretreatment verification as well potentially vivo monitoring is needed minimize neutrons. Two 3 mm long, 1 diameter organic scintillators were tested for candidacy be used a proton–neutron discrimination detector. ...
