Partin Coefficient Tables:
Prediction of Probability of Established Capsular Penetration
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
These four tables give data which allow you or you doctor to predict the probability that you have
established capsular penetration on the basis of your Gleason score, your PSA value, and your clinical stage.
In other words, these tables allow you to tell whether the prostate cancer has penetrated into and perhaps through
the "walls" or capsule of the prostate. Be careful to use the table which is based on your PSA value.
Note that the data given in these four tables are roughly the reverse of the data in the
tables predicting the probability of a patient having organ-confined disease.
Example
Harry is a 67-year-old man with a PSA of 9.8 ng/ml and a Gleason score of
2 + 3 = 5. His doctor has categorized his clinical stage as T1c since
his cancer was found solely as a result of an elevated PSA value.
Using the table for PSA values between 4.1 and
10.0 ng/ml, we find that Harry has a 27%
likelihood of established capsular penetration. In other words, there are
about 27 chances in 100 that the prostate cancer
has penetrated into Harry's prostate capsule.
Prediction of Established Capsular
Penetration
PSA = 0.0-4.0 ng/ml
| Gleason score | Stage T1a | Stage T1b | Stage T1c | Stage T2a | Stage T2b | Stage T2c | Stage T3a |
| 2-4 | 9 | 19 | 10 | 18 | 25 | 21 | ... |
| 5 | 17 | 32 | 18 | 30 | 40 | 34 | 51 |
| 6 | 19 | 35 | 21 | 34 | 43 | 37 | 53 |
| 7 | ... | 44 | 31 | 45 | 51 | 45 | 52 |
| 8-10 | ... | 43 | 34 | 47 | 48 | 42 | ... |
All numbers represent percent predictive probabilities (95% confidence interval); ellipses indicate
lack of sufficient data to calculate probability.
