SV biopsies were classified as unknown when the SV cores contained fibroadipose tissue rather than SV tissue.

Moderate or high suspicion led to histologic confirmation of SVI in 20/28 (71%) of cases.
The gray shaded areas signify the important parts of the respective tables (i.e., “SVI+” and “total” sections).
SVI=seminal vesicle invasion; US, ultrasound.
