• To characterise the costs and outcomes associated with radical prostatectomy (open, laparoscopic, or robot-assisted) and radiation therapy (RT: dose-escalated three-dimensional conformal RT, intensity-modulated RT, brachytherapy, or combination), using a comprehensive, lifetime decision analytical model.


• A Markov model was constructed to follow hypothetical men with low-, intermediate-, and high-risk prostate cancer over their lifetimes after primary treatment; probabilities of outcomes were based on an exhaustive literature search yielding 232 unique publications.

• In each Markov cycle, patients could have remission, recurrence, salvage treatment, metastasis, death from prostate cancer, and death from other causes.

• Utilities for each health state were determined, and disutilities were applied for complications and toxicities of treatment.

• Costs were determined from the USA payer perspective, with incorporation of patient costs in a sensitivity analysis.


• Differences across treatments in quality-adjusted life years across methods were modest, ranging from 10.3 to 11.3 for low-risk patients, 9.6–10.5 for intermediate-risk patients and 7.8–9.3 for high-risk patients.

• There were no statistically significant differences among surgical methods, which tended to be more effective than RT methods, with the exception of combined external beam + brachytherapy for high-risk disease.

• RT methods were consistently more expensive than surgical methods; costs ranged from $19 901 (robot-assisted prostatectomy for low-risk disease) to $50 276 (combined RT for high-risk disease).

• These findings were robust to an extensive set of sensitivity analyses.


• Our analysis found small differences in outcomes and substantial differences in payer and patient costs across treatment alternatives.

• These findings may inform future policy discussions about strategies to improve efficiency of treatment selection for localised prostate cancer.
