cost effective, but this is difficult to assess given the many

patient-, physician-, and system-level factors that affect

outcomes after prostate cancer treatment.

Conclusions

In conclusion, treatment with new technologies is costlier

than treatment with traditional technologies. However,

given the overall low quality of evidence and the incon-

sistencies across studies, precise differences in costs remain

unclear. Moreover, attempts to estimate whether this

increased cost is worth it are hampered by the uncertainty

surrounding improvements in outcomes, such as cancer

control and side effects of treatment. However, understand-

ing the value of treatment with new technologies will

become increasingly important as society and policy makers

are moving toward accountable care organizations, bundled

payments, and value-based reimbursement

[59] .

Since value

is definedas outcomes relative to cost

[60] ,

wewill needmore

accurate ways of capturing cost and outcomes of treatment

using approaches such as time-driven activity-based costing

[61]

and prospective population-based prostate cancer

registries

[62]

. We encourage clinicians and patients to

participate in such registries whenever possible.
