Proton Beams in Radiation Therapy
JNCI Journal of the National Cancer Institute, 1992The rationale for study of proton radiation therapy is that, for some anatomic sites and tumors, the treatment volume is smaller; i.e., there is less irradiation of nontarget tissue while the target is included in three dimensions at each treatment session. As a result, the dose to the target can be raised.

Alanine dosimetry of proton therapy beams
Medical Physics, 1997An analysis of some of the properties of the ESR-alanine dosimetry in therapeutic proton beams is reported. Thin alanine-based detectors (1 and 2 mm thick pellets and 0.25 mm thick films) were tested in a clinical 62 MeV proton beam. The response of the alanine detectors in unmodulated and modulated proton beams was studied in tissue equivalent ...

Proton Beam Therapy in Liver Malignancies
Current Oncology Reports, 2020Proton beam therapy (PBT) allows for improved sparing of surrounding normal tissues compared with X-ray-based radiation therapy. This is especially important in the setting of liver malignancies, where an increase in integral dose leads to a higher risk of radiation-induced liver disease (RILD) as well as close proximity to vital gastrointestinal (GI ...

An introduction to proton beam therapy
British Journal of Hospital Medicine, 2019Radiotherapy is a highly effective anti-cancer treatment commonly used alongside systemic therapies and surgery to achieve long-term cancer-free survival. Conventional radiotherapy uses photon beams to deliver a high dose of radiation to the tumour volume to eradicate cancer cells.

Proton beam therapy for hepatocellular carcinoma
Expert Review of Anticancer Therapy, 2017Radiation 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 ...

Proton beam therapy (PBT) has made it possible to deliver a higher concentration of radiation to the tumor by its Bragg-peak, and is easy to utilize due to the fact that its biological characteristics are identical with X-rays. PBT has a half-century history, and more than 40,000 patients have been reported as having had treatments with proton beams ...

Proton-Beam Therapy for Prostate Cancer
The Cancer Journal, 2010The 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 ...

Gan to kagaku ryoho. Cancer & chemotherapy, 1986
Proton beam therapy has been developed for about the last ten years as one of the most reasonable treatment techniques in cancer therapy, based upon the beneficial features of proton beams. Because of the favorable clinical results obtained further progress in this form of treatment is expected.

Proton Beam Therapy in Pediatric Oncology
The Cancer Journal, 2009Pediatric 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 ...
