Prostate Cancer Nomograms: Pre-Treatment

This nomogram can be used to predict what will happen after receiving a primary treatment (e.g. radical prostatectomy or brachytherapy). To learn more, visit our frequently asked questions.

To gather the information required below, download our PDF worksheet.

To calculate results for a specific primary treatment outcome, select an option from the list below. (Each primary treatment outcome must be selected one at a time, followed by re-clicking the "Calculate" button.) Learn more about the below primary treatment outcomes.

PSA value from the laboratory report before receiving primary therapy.
(0.1 to 100 ng/ml)
(1 to 100 yrs)

Gleason Grade

If there is more than one biopsy core that tests positive for cancer, Gleason grade should be taken from the single biopsy core with the highest Gleason primary and secondary grade.
Primary Gleason grade from the biopsy pathology report.
Secondary Gleason grade from the biopsy pathology report.
Gleason sum will be automatically calculated from the primary and secondary Gleason grade or can be entered here as a single number if the primary and secondary Gleason grade are not known.

Clinical Tumor Stages

Clinical tumor stage is determined by digital rectal examination and does not include stages determined by imaging studies.
1992 UICC clinical staging system.
1997 UICC clinical staging system

Biopsy Cores

The number of positive, or cancerous, samples taken during biopsy.
(1 to 20)
The number of negative, or noncancerous, samples taken during biopsy.
(0 to 20)

Planned or Non-Primary Treatment Information

Prescribed dose of external beam radiation therapy in Gy from consultation with radiation oncologist. (1,000 rads = 10 Gys.)
(64.8 to 86.4 Gy)
Treated with hormone therapy prior to primary treatment with radiation therapy?
Treated with external beam radiation in combination with brachytherapy?

Extent of Disease Probability

Indolent Cancer

Indolent cancer is a type of cancer that grows slowly. This tool predicts the probability that your cancer is indolent and treatment may be unnecessary.

Supporting Publication

Counseling men with prostate cancer: a nomogram for predicting the presence of small, moderately differentiated, confined tumors. J Urol. 2003 Nov;170(5):1792-7.

Organ Confined Disease

Organ confined disease is a cancer that has not spread outside of the prostate. Men diagnosed with this clinically localized prostate cancer have a number of treatment options available. To better counsel men diagnosed with prostate cancer, this tool predicts the probability that the cancer will be found confined to the prostate if the prostate is removed.

Supporting Publication

Prediction of organ-confined prostate cancer: incremental value of MR imaging and MR spectroscopic imaging to staging nomograms. Wang L, Hricak H, Kattan MW, Chen HN, Scardino PT, Kuroiwa K. Radiology. 2006 Feb;238(2):597-603. Epub 2005 Dec 12.

Extracapsular Extension

Extracapsular extension is cancer that extends through the capsule of the prostate into the surrounding tissue, as determined from the radical prostatectomy pathology report. This tool predicts the overall likelihood that there is extracapsular extension and can further assess the probability of extracapsular extension on the left or right side of the prostate if the optional, enhanced clinical features are entered in the nomogram.

Prediction of Organ Confined Prostate Cancer: Incremental Value of MR Imaging and MR Spectroscopic Imaging to Staging Nomograms, Radiology, 2006, volume 238, pages 597- 603.

Seminal Vesicle Invasion

Seminal vesicle invasion means the prostate cancer has spread into the seminal vesicles, a gland attached to the prostate that helps produce the semen. This tool predicts the probability that the prostate cancer has spread to one or both seminal vesicles. A more accurate prediction can be made when the optional, enhanced data is entered.

Supporting Publication

A nomogram to predict seminal vesicle invasion by the extent and location of cancer in systematic biopsy results. J Urol. 2003 Oct;170(4 Pt 1):1203-8.

Lymph Node Involvement

This tool predicts the probability that prostate cancer has spread to the pelvic lymph nodes.

Primary Treatment Outcomes

Progression Free Probability after Radical Prostatectomy

This tool predicts the five and 10 year probability that the PSA will remain undetectable and that prostate cancer will not progress or recur after radical prostatectomy.

Supporting Publication

Preoperative nomogram predicting the 10-year probability of prostate cancer recurrence after radical prostatectomy. J Natl Cancer Inst. 2006 May 17;98(10):715-7.

Probability of Cancer-Specific Survival

This tool predicts the probability that a patient with these specific characteristics will NOT have died of prostate cancer within 10 or 15 years after radical prostatectomy. This prediction does not exclude the possibility that the patient will die of other causes within that time.

Supporting Publication

Prostate cancer-specific mortality after radical prostatectomy for patients treated in the prostate-specific antigen era. J Clin Oncol 2009; 27:4300-5.

Progression Free Probability with Brachytherapy

Brachytherapy is a procedure in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor. This tool predicts the probability that cancer will not recur at five years for patients treated with brachytherapy for localized prostate cancer.
