Feature Article

Adverse Events Appear Common Following Prostate Biopsy for Elevated PSA Level   

 

A large body of research suggests that prostate specific antigen (PSA) testing to screen for prostate cancer may not reduce all-cause or prostate-cancer specific mortality (BMJ 2010 Sep 14;341:c4543, Cochrane Database Syst Rev 2010 Nov 10;(11):CD004720). The American Cancer Society recommends that asymptomatic men should have the opportunity to make informed decisions before having a PSA screen (CA Cancer J Clin 2010 Mar-Apr;60(2):70). If a screening test shows high PSA levels, a prostate biopsy is indicated to determine if cancer is present. A recent cohort study investigated the rates of adverse events associated with prostate biopsy.

 

A total of 1,147 men (mean age 62 years, mean PSA level 5.4 ng/mL) had a 10 core transrectal ultrasound-guided biopsy performed with antibiotic prophylaxis. The men completed a questionnaire about pain, infection, and bleeding at time of biopsy and at 7 and 35 days after the biopsy. Pain was reported by 44% within 35 days of the procedure, with 7% reporting it as a moderate to serious problem. Bleeding was also common (urinary bleeding in 66%, rectal bleeding in 37%, blood in semen in 93%). Fever occurred in 18% and shivers in 19%. At 7 days after the biopsy, 19.6% reported that repeat biopsy would be a moderate to major problem. Factors associated with negative attitudes toward repeat biopsy included pain immediately following biopsy (odds ratio [OR] 12.1), pain at 7 days after biopsy (OR 8.2), symptoms related to infection (OR 7.9), and bleeding (OR 4.2) (level 2 [mid-level] evidence) (BMJ 2012 Jan 9;344:d7894). These findings may be of use to patients and their care providers when considering the risks and benefits of prostate cancer screening.
