Partin Coefficient Tables:
Prediction of Seminal Vesicle Involvement

Last Revised May 14, 1997

[NOTE: The tables were updated in June, 2001, and are at the site of Dr. Oppenheimer's pathology lab. He is the author of "Partin Table Predictions: What Do They Really Mean?" here at InfoLink.]

Introduction | Example
PSA = 0.0-4.0 ng/ml | PSA = 4.1-10.0 ng/ml | PSA = 10.1-20.0 ng/ml | PSA = 20.1 ng/ml or more

Introduction

The following four tables give data which allow you or you doctor to predict the probability that prostate cancer has spread out of your prostate into the seminal vesicles on the basis of your Gleason score, your PSA value, and your clinical stage. Be careful to use the table which is based on your PSA value.

Example

Gary is a 70-year-old man with a PSA of 3.2 ng/ml and a Gleason score of 2 + 2 = 4. His doctor has categorized his clinical stage as T1a since he found a very small amount of cancer in tissue removed during a transurethral resection of the prostate (a TURP), which had been carried out to relieve Gary's problem with frequent and incomplete urination.

Using the table for PSA values between 0.0 and 4.0 ng/ml, we find that Gary has a 0% likelihood of prostate cancer involving his seminal vesicles. In other words, it is all but certain that Gary's cancer is does not extend into the seminal vesicles.
