Abstract

Background

Gleason Score (GS) upgrading is generally considered a trigger for exit to definitive treatment during active surveillance (AS). Predicting the potential for GS upgrading would be of value in assessing AS eligibility.

Methods

We assessed the performance of biomarkers in presurgical specimens of expressed prostatic secretion (EPS) in this setting.

Results

Although EPS volume, total recovered RNA, and RNA expression biomarkers (TMPRSS2: ERG, PCA3, PSA) have been successful in both biopsy outcome prediction, and in the prediction of upstaging in active surveillance eligible patients, they were unable to predict upgrading in patients eligible for active surveillance under National Comprehensive Cancer Network guidelines.

Conclusions

These biomarkers do not improve the prediction of upgrading over indications from standard clinical parameters.
