Coefficient Tables:
Prediction of Lymph Node Involvement
Last Revised September 25, 1997
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 lymph nodes 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
Mike is a 62-year-old man with a PSA of 8.4 ng/ml and a Gleason score
of 4 + 2 = 6. His doctor has categorized his clinical stage as T2b since
he was able to feel a significant induration in one lobe of Mike's
prostate on DRE and the biopsy and ultrasound indicated that the cancer
had invaded more than half of that lobe but there was no sign of cancer
in the other lobe.
Using the table for PSA values between 4.1 and
10.0 ng/ml, we find that Mike has an 4% likelihood of prostate
cancer which has invaded his lymph nodes. In other words, there are
about 19 chances in 20 that Mike's cancer has not invaded the
lymph nodes.
