PURPOSE Overtreatment of screen-detected localized prostate cancer (LPC) is an important public health concern, since the survival benefit of aggressive treatment (surgery or radiation) has not been well established. We investigated the survival expectations of patients who had LPC with and without their chosen treatment.
METHODSA population-based sample of 260 men (132 black, 128 white) 75 years old or younger with newly diagnosed LPC completed a self-administered survey. How long the patients expected to live with their chosen treatment, how long they would expect to live with no treatment, and factors associated with the difference in perceived life expectancy were assessed using multivariable analysis.
RESULTSWithout any treatment, 33% of patients expected that they would live less than 5 years, 41% 5 to 10 years, 21% 10 to 20 years, and 5% more than 20 years. With their chosen treatment, 3% of patients expected to live less than 5 years, 9% 5 to 10 years, 33% 10 to 20 years, and 55% more than 20 years. Treatment chosen, age, general health perception, and perceived cancer seriousness predicted the differences in perceived life expectancy, while race and actual tumor risk did not. After adjustment for other covariates, men who choose surgery or radiation expected greater gain in survival than men who chose watchful waiting or active surveillance.CONCLUSIONS Most patients with LPC underestimated their life expectancy without treatment and overestimated the gain in life expectancy with surgery or radiation. These unrealistic expectations may compromise patients' ability to make informed treatment decisions and may contribute to overtreatment of LPC. Primary care physicians, when included in the decision process, should focus on helping patients develop realistic expectations and choices that support their treatment goals.

INTRODUCTION
Due to the growing concerns about overtreatment of localized prostate cancer (LPC), practice guidelines now include observationthat is, watchful waiting or active surveillance (WW/AS)-as an appropriate initial management strategy for low-risk LPC.1,2 Observation, however, is used for only about 10% to 20% of patients.3-6 Moreover, aggressive treatment of LPC, including low-risk LPC, is increasing. 4,7 Although new technology may be a reason men choose aggressive treatment, anxiety and fear of cancer progression is often cited as the reason for the low uptake of observation. [8][9][10][11] Yet the survival benefit of aggressive treatment (ie, surgery or radiation) for LPC has not been demonstrated in a PSA-screened population. In fact, the Prostate Cancer Intervention Versus Observation Trial (PIVOT) showed that surgery did not significantly reduce all-cause or prostate-cancer-specific mortality as compared with observation through a median of 10 years of follow-up.
12To make informed treatment decisions, patients with LPC need a realistic understanding of the likely benefits and harms of each treatment option. Few studi...
