Proton Therapy for Prostate Cancer
Non-invasive, Minimal Side Effects, Excellent Cure Rates

Proton therapy (or proton treatment) for prostate cancer has many advantages over conventional therapy. Unlike other types of radiation therapy that use x-rays to destroy cancer cells, proton therapy uses a beam of proton particles. By using protons, doctors can direct the radiation to the tumor with pinpoint accuracy. This means less damage to surrounding healthy organs and tissue, and the ability to deliver a higher dose of radiation to the tumor.

Proton Therapy Surveys & Studies

2014 NAPT Proton Patient Survey: The National Association for Proton Therapy (NAPT) commissioned Dobson DaVanzo & Associates, a healthcare consulting firm, to investigate clinical outcomes and patient satisfaction among men treated with proton therapy for prostate cancer. They were asked to compare these results to those from a 2013 survey (see below). In total, about 3,800 former patients from 12 proton centers responded to the survey. Many who responded to this survey were treated 10, 15, and even 20 or more years ago.

Key Findings: As in past surveys, patients continue to be extremely satisfied with their proton therapy treatment:

2013 Proton Patient Survey: A Prostate Cancer Report commissioned by NAPT was released at the National Proton Therapy Conference in Washington, D.C. on February 13, 2013 – Ninety nine percent of proton therapy patients believe they made the best prostate cancer treatment decision for themselves. Approximately 96% were satisfied or extremely satisfied with proton therapy; 92% reported that their quality of life was better or the same today than it was before proton therapy; 92% reported that physical health or emotional problems did not interfere, or interfered very little with their social activities; when looking at patients who received only proton therapy for the treatment of prostate cancer (did not receive hormone or photon therapy), proton therapy patients reported lower HRQOL measures than non-treated individuals in only one HRQOL category.
