A new study shows "extremely high efficacy" in 5-year outcomes for patients in all risk categories treated with proton-beam therapy. The 5-year rates of freedom from biochemical and/or clinical progression were 99% in low-risk patients, 99% in inte rmediate-risk patients, and 76% in high-risk patients.
The 5-year overall survival rates were 93%, 88%, and 90%, respectively, for the 3 risk categories.
The study was published in the March 1 issue of the International Journal of Radiation * Oncology * Biology * Physics. http://www.redjournal.org/article/S0360-3016%2813%2903310-5/abstract#.VJRIwtbDHXY.facebook
