The transrectal ultrasound-guided (TRUS) prostate needle biopsies were shown to not fully catch anterior-predominant prostate cancers.
"Although a small study, this is a unique cohort who underwent extensive sampling at re-biopsy that confirmed the presence of an anterior-predominant tumor" stated Dr. Morgan. "These results indicate that an epigenetic assay may be valuable even in patients with negative posteriorly-directed TRUS biopsies to detected anterior-predominant PCa."
