Kris great paper on the Pros of PBRT.
The issues that carriers have are just before the conclusion:
A Randomized Study Comparing Photons and Protons?There has already been a great deal of discussion in the literature regarding the feasibility of a randomized study comparing PT and IMRT for prostate cancer, which is an issue beyond the scope of this review.It is unclear how much dose escalation and dose intensification the improved dose distri-bution from PT will permit.
Thus, at this point in time, the degree of benefit achievable with PT is unknown, so it seems premature to commit significant resources to a randomized trial testing a mature technology against an immature technology. Funds and research resources would be better spent at this point in developing PT and in determining how best to maximize its benefits.I italicized the problem carriers are having. This statement does not help the pro-PBRT groups at all. If after 20+ years of charging 100k to treat PCa and not fund trials to prove it's efficacy statements then why fund the procedure at all is what we are seeing today by denial of service for PBRT.
It really does not follow logic to acknowledge the lack of trials comparing technologies by saying it's too costly when you are charging the highest dollars to perform such treatment.
