Proton-Beam Therapy for Prostate Cancer

The Cancer Journal, 2010
The treatment options for prostate cancer include prostatectomy, external-beam irradiation, brachytherapy, cryosurgery, focused ultrasound, hormonal therapy, watchful waiting, and various combinations of these modalities. Because the prostate abuts the bladder and rectum, the dose distributions of external-beam irradiations and the accuracy of their ...

Proton beam therapy for hepatocellular carcinoma

Expert Review of Anticancer Therapy, 2017
Radiation therapy is an effective treatment option for hepatocellular carcinoma (HCC) patients. However, radiotherapy for HCC still has limited recognition as a standard treatment option in international consensus guidelines due to a paucity of randomized controlled trials and the risk of hepatotoxicity, which is primarily mediated by baseline liver ...

Alpha Particle and Proton Beams in Therapy

JAMA: The Journal of the American Medical Association, 1963
HEAVY PARTICLES, either charged or uncharged, are called "heavy" because they actually are very heavy when compared with the weight of the electron. The neutron is approximately 1,800 times the weight of the electron and, in the case of other heavy particles, such as alpha particles, carbon nuclei, and other elements higher in the periodic table, they ...

Proton-beam therapy for tumors of the CNS

Expert Review of Neurotherapeutics, 2010
The focus of this review is proton radiotherapy for primary neoplasms of the brain. Although glial cells are among the most radioresistant in the body, the presence of sensitive critical structures and the high doses needed to control CNS tumors present a formidable challenge to the treating radiation oncologist.

Childhood cancer and proton beam therapy

BMJ, 2014
Promising new treatments need a strong evidence base Survival of UK children with cancer is showing sustained improvement, with the proportion of under 15s living five years after diagnosis now at 82%.1 With more young people facing the prospect of long term cure, focus has moved from “cure at all cost” to “the cost of cure.” This is particularly ...

Proton-Beam Therapy for Olfactory Neuroblastoma

International Journal of Radiation Oncology*Biology*Physics, 2007
To analyze the feasibility and efficacy of proton-beam therapy (PBT) for olfactory neuroblastoma (ONB) as a definitive treatment, by reviewing our preliminary experience. Olfactory neuroblastoma is a rare disease, and a standard treatment strategy has not been established.

Proton beam therapy for pediatric ependymoma

Pediatrics International, 2015
AbstractBackgroundThe aim of this study was to evaluate the efficacy of proton beam therapy for pediatric patients with ependymoma.MethodsProton beam therapy was conducted for six patients (three boys and three girls; age, 2–6 years; median, 5 years) with ependymoma. The tumors were WHO grades 2 and 3 in two and four patients, respectively.

Proton Beam Therapy in Pediatric Oncology

The Cancer Journal, 2009
Pediatric caregivers and parents are eager to know the role of proton beam therapy (PBT) in the treatment of children with brain and solid tumors and other diseases for which radiation therapy is indicated. Although the number of children treated with PBT for the most common pediatric tumors is relatively small and outcome data are clearly lacking ...
