In the analysis of 10,472 men from 1990 to 2013, use of surveillance for low-risk disease rose sharply in 2010 through 2013, to 40% of cases. Use of surveillance had previously remained low, at between 7% and 14%, from 1990 through 2009.
Dr. Matthew Cooperberg did the study with Dr. Peter Carroll, both of the University of California, San Francisco, to analyze recent trends in community-based patterns of managing localized prostate cancer.
Data from the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) were used. This is a national registry of men with prostate cancer cared for since 1995 across 45 US urology practices.
The study included men with tumors classified as stage cT3aNoMo or lower managed with prostatectomy, radiation, androgen deprivation monotherapy, or active surveillance/watchful waiting between 1990 and 2013.
