Added Criteria May Identify Prostate Cancer Surveillance Candidates

Additional predictors, such as PSA density and extent of cancer on biopsy, help guide selection of prostate cancer (PCa) patients for active surveillance programs, according to research published in The Journal of Urology. (2014;191:350-357).

To identify predictors of adverse pathology, Annelies Vellekoop, MD, of New York University, and colleagues analyzed data for 4,500 men who underwent radical prostatectomy for Gleason 6 prostate cancer. The researchers included a subset with extended biopsy data.

Based on the inclusion criteria of six currently published active surveillance protocols, 33%-45% of men with clinically localized Gleason 6 PCa had adverse pathology at radical prostatectomy. Predictors of upgrading and up staging among patients with Gleason 6 PCa included older age, higher levels of PSA, PSA density greater than 0.15 ng/ml/cm³, palpable disease, and extent of cancer greater than 4 mm on biopsy. Larger prostate volume was inversely related to adverse pathology.

"More than a third of men meeting the most stringent active surveillance criteria had adverse pathology at radical prostatectomy in this population-based cohort," the authors wrote. "Active surveillance programs should consider PSA density and extent of cancer on biopsy for patient selection."
