Introduction, FAQ, and Contact Information


There are multiple validated tools to estimate prognosis in patients with advanced cancer. However, there are several barriers towards their regular use in clinical practice:

  1. It is difficult to choose which tool to use.
  2. The calculation can be cumbersome, especially with multiple models.
  3. The interpretation can be challenging.

In an attempt to try and overcome these challenges, we have created this website to provide survival estimates based on multiple prognostic models based entirely on published results that are referenced.

Currently, the models we have included are:

As well as predictions based solely on the following Performance Status Scales:

Q: Why don't you include prognostic model X, Y or Z?

A: There are a lot of prognostic models out there and more are being developed all the time. If you have any suggestions about other prognostic models please email us! However, we have initially started with

Q: The website is blocked at the hospital/clinic I work, but I can use it at home, why?

A: Many hospitals use extra security software programs that check websites against their own "whitelist" of known, safe website domains to prevent hackers from stealing protected health information. Since our website is new (the domain was registered in early March 2017) it may be several weeks to months before each individual software company tests and approves it. If you find the website blocked, I would appreciate an email (JP Maxwell) with the name of the software program blocking it so I can contact the company and get the website whitelisted sooner.

Q: Where was the background picture taken?

A: This was taken on a hike in the foothills surrounding the Yakima Valley in the fall after some rain.


We are continually refining the website based on our own use and feedback from other providers so if you have any suggestions, notice an error or have a criticism please don't hesitate to email us:
