Use of Age and Medical Comorbidity to Assess Long-term Other-cause Mortality Risk in a Cohort of Men Undergoing Prostate Biopsy at an Academic Medical Center
To assess life expectancy and biopsy outcomes in men undergoing prostate biopsy at an academic medical center.We analyzed men who underwent prostate biopsy at our medical center between July 2012 and June 2014. Long-term other-cause mortality risk was determined using survival tables. Indications for biopsy and biopsy outcomes were assessed, and compared among men with varying mortality risks.A total of 417 men underwent prostate biopsy, in whom 14-year other-cause mortality risk ranged from 9% to 74%. One hundred ninety-three men (46.3%) were considered low-mortality risk (40% risk of 14-year mortality), 131 (31.4%) intermediate risk (41%-55% 14-year mortality), and 93 (22.3%) high risk (55% 14-year mortality). Of the 417 patients who underwent biopsy, 149 (35.7%) were found to have prostate cancer. There was no significant difference in the rate of positive biopsies (P = .72), distribution of Gleason scores (P = .60), or percentage of positive biopsy cores (P = .74) between mortality risk groups. However, by UCSF Cancer of the Prostate Risk Assessment score, there was significant trend toward higher-risk prostate cancer in men with intermediate and high-mortality risk (P = .04).In this analysis, a large number of men with limited life expectancies underwent prostate biopsy. The majority of these men had negative biopsies or low-risk cancers, suggesting that they were unlikely to benefit from biopsy. To avoid potentially unnecessary prostate biopsies, the practitioner must give serious consideration to a patient's age and medical comorbidities before making a recommendation as to whether biopsy should be performed.
