Roach formula (Seminal Vesicle) - Evidencio
Roach formula (Seminal Vesicle)
A simple equation for estimating the risk of seminal vesicle invasion was derived from a nomogram published by Partin et al. demonstrating the value of combining the pre-treatment prostate specific antigen and Gleason Score in predicting the risk of seminal vesicle invasion for patients with clinically localized prostate cancer. The risk of positive seminal vesicles (SV+) was calculated using the equation; SV+ = (PSA) + (10 * ((Gleason score) - 6)).

Conditional information

The risk of seminal vesicle invasion supports decision making for urologists and oncologists regarding the extent of primairy treatments such as radical prostatectomy or radical radiation therapy in patients diagnosed with prostate cancer.
