Treating Patients With Proton Therapy

Proton therapy is an effective radiation treatment for many types of tumors. Because protons can be more precisely controlled than standard X-ray radiation, they deliver a lower dose of radiation to healthy tissue, which is particularly important when a tumor is close to a critical organ or structure such as the brain or spinal cord.1-3 Patients treated with protons experience fewer short- and long-term side effects, including a decreased risk of secondary malignancies, compared with the standard forms of radiation therapy.4-6 The greater precision of proton therapy also allows higher doses of radiation to be delivered, providing better control without increased adverse effects.1,7

*Biochemical failure defined using the American Society for Therapeutic Radiology and Oncology criteria of 3 successive increases in PSA level with failure backdated to a point halfway between first increase and last non-increasing value.
† Local control defined as post-treatment PSA level >1 ng/mL within 2 years or subsequently increased to that level


The table above shows the results from a randomized controlled trial of 392 patients with prostate cancer. X-rays were used to provide a fixed dose of 50.4 Gy and proton therapy to provide the boost dose to either 70.2 Gy (conventional) or 79.2 Gy (high). The high dose provided significantly better freedom from biochemical failure and local control than the conventional dose and had similarly low rates of grade 3 morbidity.

Clinical Indications

Many patients with cancers and solid tumors can benefit from proton therapy. Tumors commonly treated with protons include prostate, brain, pediatric, base-of-skull, juxtaspinal cord, non-small-cell lung, gastrointestinal, and melanoma of the eye.
