Original Source: Management of Rising Prostate-specific Antigen After a Negative Biopsy.

Prostate biopsy remains one of the most commonly performed urologic office procedures. A significant percentage of men with a negative result may have unrecognized disease. Inadequate biopsy strategies or findings of high-grade prostatic intraepithelial neoplasia or atypia increase this likelihood. The term "negative biopsy" may be misleading. Traditional sextant biopsy is inaccurate and extended- or saturation-biopsy protocols miss small cancers. A rising prostate-specific antigen (PSA) after a negative pr...
