Comparison With Other Treatment Options
The issue of when, whether, and how best to apply this technology is controversial. As of 2012 there have been no controlled trials to demonstrate that proton therapy yields improved survival, or other clinical outcomes (including impotence in prostate cancer) compared to other types of radiation therapy, although a 5-year study of prostate cancer is underway at Massachusetts General Hospital. Proton therapy is far more expensive than conventional therapy. Using current technology, proton therapy requires a very large capital investment (from $100M to more than $180M).
Preliminary results from a three-year 2009 study, including high dose treatments, show very few side effects.

Famous quotes containing the words comparison with, comparison and/or treatment:
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
“Most parents aren’t even aware of how often they compare their children. . . . Comparisons carry the suggestion that specific conditions exist for parental love and acceptance. Thus, even when one child comes out on top in a comparison she is left feeling uneasy about the tenuousness of her position and the possibility of faring less well in the next comparison.”
—Marianne E. Neifert (20th century)
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the child’s duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
