Seminal vesicle invasion by prostate cancer: prognostic significance and therapeutic implications

Seminal vesicle invasion by prostate cancer: prognostic significance and therapeutic implications

S R Potter et al. Rev Urol. 2000 Summer.

Abstract

When the pathologist's report following radical prostatectomy describes seminal vesicle invasion (SVI), generally the outlook for the patient is poor. But are we all on the same page of the same book when we talk about SVI? Does it mean muscular wall invasion? Does it include the ejaculatory duct? Getting a clear definition can have far-reaching clinical implications for patient prognosis and treatment.
