Some urologic measurements look simple but can be misleading without their formula. Metastatic Prostate Cancer Prognosis Calculator turns the fields shown in this tool into the specific result it was built to calculate.

What this calculator does

Metastatic Prostate Cancer Prognosis Calculator uses Age, Height, Weight, Gleason score, Distant metastases, Health level, and Are you a smoker to calculate estimated 5-year overall survival. Where supported, it also shows Estimated 10-year survival and BMI so the primary result is easier to check. It follows the exact field flow and engine behavior in this plugin rather than describing a different calculator with the same name. Kidney and urologic calculations often summarize one narrow measurement or historical model. Results should be read with symptoms, laboratory trends, imaging, pathology, and the clinical question that prompted the test.

How to use it

Enter or select Age, Height, Weight, Gleason score, Distant metastases, Health level, and the remaining fields shown. Use the units offered by the calculator and keep paired laboratory or treatment values from the same clinical episode whenever the formula assumes that. If an entry is unknown, do not substitute a guess simply to obtain a number.

How the calculation works

The implemented model first calculates BMI from weight and height, then builds a composite risk value from age above 50, the selected Gleason-score band, distant-metastasis status, general health level, smoking, and BMI above 25. It converts that composite through a logistic equation to an estimated 5-year overall-survival percentage; the 10-year value is set to 72% of the 5-year estimate.

Example

Using the sample values prefilled in this calculator, the primary result is 62.29% (Estimated 5-year overall survival), Estimated 10-year survival is 44.8%, and BMI is 26.1. This example demonstrates the plugin’s own calculation path; replace the sample inputs with verified values before interpreting a real result.

How to interpret the result

Read the percentage only as the plugin’s approximate population-level estimate from its limited inputs. It is not a personal life-expectancy forecast and should not be used to compare treatments.

Limitations and notes

The plugin explicitly documents this as a population-level composite with proprietary/source-model calibration not exactly reproduced. It should not be used as an individualized cancer-survival prediction. Modern prognosis depends on disease volume/site, tumor biology, treatment, performance status, laboratory values, and response to therapy.
