Patient preference and the impact of decision-making aids on prostate cancer treatment choices and post-intervention regret

The number of prostate cancer survivors is rapidly growing in the Western world. As a result of better oncologic outcomes, more patients are living longer with the adverse effects of treatment, which can be both functional and psychological. Clinicians, in an era of shared decision-making, must not only cure the cancer, but also ensure that, after treatment, their patients experience the best quality of life and minimal post-treatment decisional regret. To participate in the decision-making process, men and their involved partners and family need to fully understand the relative benefits and harms of prostate cancer treatments. Patient preference studies indicate that men with prostate cancer are not well informed. Decision-making aids are a positive treatment adjunct both to convey information and to allow patients to explore their own beliefs and values during the decision-making process. The evidence suggests that decision-making aids better prepare patients for involvement in treatment decisions, but further studies are required to investigate the relationship between the use of decision-making aids and post-treatment decisional regret in prostate cancer.
