SEMINAL VESICLE INVOLVEMENT BY PROSTATE CANCER.
The authors divide seminal vesicle invasion into 3 types:
1. Direct spread along the ejaculatory duct into the seminal vesicle.
2. Extracapsular prostate spread onto and through the seminal vesicle
capsule.
3. Isolated deposits of cancer in the seminal vesicle,
with no contiguous primary cancer in the prostate.
The authors suggest that type 3 invasion has a more favorable prognosis
than the other 2 types.
