Post-Radical Prostatectomy

Our post-radical prostatectomy nomogram can be used by patients after their surgical treatment for prostate cancer. Using a dynamic statistical formula, this nomogram predicts the probability of remaining cancer recurrence-free at two, five, seven, and ten years following surgery. This nomogram also predicts 15-year cancer-specific survival, meaning the likelihood that you will NOT die of prostate cancer within 15 years following surgery.

The results of this nomogram will apply to you if radical prostatectomy was the only treatment you received for your prostate cancer AND if your serum PSA level has been undetectable (less than 0.05 ng/mL) since surgery. If you received radiation therapy or hormone therapy (Lupron, Taxotere, Casodex, Eulexin, Zoladex, etc.) prior to surgery, the calculations of this nomogram will not be accurate.

Prostate cancer recurrence is present after radical prostatectomy when the PSA measurement has reached 0.2 ng/mL and continues to rise, and has been confirmed as such on a repeat measurement.

Results produced by this tool are based on studies conducted at large research institutions with surgeons who perform a high volume of prostate cancer procedures. All results must be understood in the context of each patient’s specific treatment plan. Patients and caregivers using this tool should discuss the result with the patient’s physician.

Disqualifying Treatments

If you have received either hormone or radiation therapy for prostate cancer — if you answer “yes” to either of the following two questions — the results of this nomogram will not apply to you.

General Information

What is a dynamic nomogram?

Most medical prediction models come from published studies based on fixed groups of patients. The statistical formulas for these models therefore do not change as new information becomes available. In contrast, the "dynamic" model used here — with the exception of the calculation for survival probability — draws on data from more than 10,000 prostate cancer patients treated at MSK. The model is updated several times a year as the MSK database accumulates new data, with more recent patients given more weight in the statistical analysis than patients treated many years ago. As a result, the statistical formula for the model changes slightly over time.

What is your Gleason score?

How are Gleason patterns/scores determined?
Physicians characterize the aggressiveness of prostate cancer using the Gleason scoring system, which provides an estimate of the cancer’s potential to grow and spread to other parts of the body. The pathologist determines the Gleason pattern based on how closely the cells of the gland resemble those of a normal prostate. All the cores of tissue taken during a biopsy are examined by a pathologist, who assigns a pattern number to the largest area of cancer in each core (known as the primary Gleason pattern), and a second pattern number to the next most common area (known as the secondary Gleason pattern). The two pattern numbers added together are the Gleason score. If more than one biopsy core contains cancer cells, the patient’s overall Gleason score is determined by the core with the highest Gleason score.
The score will be automatically calculated from the sum of the primary and secondary Gleason pattern numbers, or it can be entered here as a single number if the primary and secondary Gleason pattern numbers are unknown.
If you enter this score manually
If you don’t know your primary and secondary Gleason pattern, but only the total score, you can enter it directly. The result will be slightly less accurate, but still close to the true value.

Prostatectomy Pathology Report Details

What are positive surgical margins?
Surgical margins are positive if cancer cells are present at the edges of the removed prostate.
What is extracapsular extension?
Extracapsular extension is cancer that extends into or outside the prostate “capsule” or organ, as determined from the radical prostatectomy pathology report.
What are seminal vesicles?
The seminal vesicles are glands that help to produce semen.
What are pelvic lymph nodes?
The pelvic lymph nodes are small glands that filter fluid made in the prostate; they can be an early site of prostate cancer spread.
