Our pre-radical prostatectomy nomogram is for patients diagnosed with prostate cancer who have not yet begun treatment. This nomogram predicts the extent of the cancer and long-term results following radical prostatectomy (surgery to remove the prostate gland and surrounding lymph nodes). Using a dynamic statistical formula, this nomogram draws on data from more than 10,000 prostate cancer patients treated at MSK. more…
You can use this nomogram for applicable results if you have received no hormone or radiation therapy for prostate cancer. If you are receiving either form of therapy for your prostate cancer, the results of this nomogram will not be accurate.
Results produced by this tool are based on data from patients treated at MSK — a large research institution 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.
To gather the information required to use this nomogram, use our worksheet.
Please note: This dynamic nomogram summarizes the benefits of treatment in men with life expectancy greater than ten years. The calculations are based on data from men who survived ten to 15 years following treatment. (You can calculate your life expectancy here, as well as your risk of dying from prostate cancer if it is left untreated.)
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.

Note: If you have received hormones, radiation, or any other therapy for your cancer, the PSA level following these treatments will not be applicable.
The global standard in prostate cancer staging is the TNM Staging System, which uses tumor, lymph node, metastasis (TNM) classifications to describe the extent of cancer in a patient's body. T describes the size of the tumor and whether it has invaded nearby tissue; N describes whether regional lymph nodes are involved and, if so, how extensively; and M describes whether distant metastasis (spread of cancer from one body part to another) is present.
The system is maintained by the Union for International Cancer Control (UICC) and the American Joint Committee on Cancer (AJCC) and is updated periodically, most recently in 2009/10 (Version 7).
The following are clinical tumor stages for prostate cancer from the 2010 edition.These stages are listed on the pathology report.
If you are a patient, print the Pre-Radical Prostatectomy Worksheet and bring it with you to your next appointment. The worksheet contains a list of what you need to use this prediction tool.
