  UroToday - Prognostic Nomograms
Aside from being accurate, the ideal nomogram should not be culturally biased, pathologist or surgeon dependent, and should apply to the patient in the community and not the well selected patient commonly seen in tertiary care institutions.
Although some have criticized this nomogram for using a definition of > 0.4 ng/ml for PSA recurrence, this nomogram has been validated with a cohort of over 6700 patients from different institutions and its results were consistently accurate independent of the definition of failure used by the institution.

Patients with seminal vesicle involvement by tumor are considered by most urological surgeons to be inoperable because of a high chance of metastatic spread and so are better treated by other means.
A nomogram that incorporated this variable produced probabilities of SVI that differed from the standard model by <10% in 68% of the cases.
Clinical scenario 2: Using Nomogram 2, let us now enter data for a patient presenting with a PSA = 6 ng/ml (85 points, which is derived by vertically drawing a line from the PSA line at the 6 value up to the Points line (the point of intersection is the value of 85).

 The number needed to treat
This nomogram could be used alongside the one proposed by Sackett et al (7) in their book for applying Bayes' formula when assessing the informative value of diagnostic tests, either for interpreting the results of a therapeutic trial, or for making therapeutic decisions in the individual patient.
Using the nomogram, the number needed to treat can be directly obtained without any calculation by drawing a straight line from the point corresponding to the proportion of events in the control group on the left-hand scale to the point corresponding to the relative risk reduction measured in the trial on the central scale.
The nomogram makes it very easy to calculate that, if the same 39% reduction of the 5-year risk of mortality does exist in each subgroup (see discussion of this point below), 40, 18 and 10 patients needed to be operated on to avoid one death in the lowest, middle and highest tertiles of risk respectively.

Study investigators then prospectively applied the nomogram to 373 patients whose breast cancer was detected through biopsy in the sentinel lymph nodes and found that the prognostic model accurately predicted the likelihood of axillary lymph node metastasis to within a few percentage points.
The nomogram takes several pathological factors into account, including tumor size; tumor type (ductal or lobular); estrogen-receptor status of the primary tumor; the method of detection of sentinel lymph node metastases (frozen section analysis, routine analysis, or enhanced pathologic analysis); and the number of positive and negative sentinel lymph nodes.

A nomogram is a sheet of paper with graduated scales (for example for temperature, pressure, and potential temperature).
Making a basic nomogram is easy; making a nomogram with the right ranges which has readable scales and which incorporates two calculations at the same time is rather less easy.
Postscript printers are essentially big programmable RPN calculators and are ideally suited to produce graphics such as these: the locations of the scales and their graduations are calculated by the printer itself before they are plotted.

 Pre-Surgery Nomogram - 5 yrs
Here is a nomogram that predicts the possibility of recurrence at 5 years, standardized Internationally.
Nomogram predictions for each risk quadrant were similar to actual freedom from recurrence rates: predicted probabilities of 87% (low-risk group), 64% (intermediate-low—risk group), 39% (intermediate-high—risk group), and 14% (high-risk group) corresponded to actual rates of 86%, 64%, 42%, and 17%, respectively.
The use of neoadjuvant therapy, variation in the prostate-specific antigen recurrence definitions between institutions, and minor differences in the way the Gleason grade was reported did not substantially affect the predictive accuracy of the nomogram.

 New Markers Predicting Prostate Cancer Outcome
Physicians often use a tool called a nomogram that uses features of a patient's tumor to predict the risk of progression of their prostate cancer.
We have found the nomogram to be a very accurate predictor of prostate cancer progression in patients who are going to have a radical prostatectomy.
In addition, we are developing and validating nomograms incorporating these markers for our patients who have already undergone a prostatectomy, who are undergoing or contemplating radiation therapy for treatment of prostate cancer, or who have developed recurrence after one of these therapies.

 Hospital News 2005 - Northwestern Memorial Hospital - Chicago
08/03/2005 - A cardiologist with the Bluhm Cardiovascular Institute of Northwestern Memorial Hospital led the development of a nomogram (alignment chart) specifically for women that can be used to predict their expected exercise capacity at any given age, as well as demonstrated that the resulting measure is a predictor of the risk of death.
To utilize the nomogram to establish the percentage of predicted exercise capacity for age requires only the woman's age and exercise capacity achieved in MET on the exercise stress test.
The nomogram was then used to determine the percentage of predicted exercise capacity for both cohorts.
