Download SAS and Gauss Code for the Colorectal Cancer Risk
Calculation Engine
The CCRAT may be updated periodically as new data or research becomes available.
The algorithm was last updated in October 2014. The current software version is 1.1. Estimates for "I don't know" categories were added.
What You’ll Download
Colon Cancer Risk Assessment Tool SAS Macro
The CCRAT SAS macro allows the user to project absolute colon cancer risk according
to NCI’s Colon Cancer Risk Assessment Tool (CCRAT) algorithm in batch mode. Risk
factor data and projection interval ages can be entered for a group of men or women,
and corresponding absolute risk projections will be returned. This program may be
useful for research purposes when one needs risk projections for an entire study
population.
You can download ZIP files containing the macro code and
documentation for the colorectal cancer risk calculation engine. Separate
downloads are available for male and female macros.

Colon Cancer Risk Assessment Tool Gauss Program
The CCRAT Gauss Program is an executable that allows the user to project absolute
colon cancer risk according to NCI’s Colon Cancer Risk Assessment Tool (CCRAT) algorithm
in the batch mode. It also computes 95% confidence intervals for the risk projections.
Risk factor data and projection interval ages can be entered for a group of men
or women, and corresponding absolute risk projections will be returned. This program
may be useful for research purposes when one needs risk projections for an entire
study population. The program requires either a 32-bit or a 64-bit system.
You can download ZIP files containing the program code for the colorectal cancer
risk calculation engine. Separate downloads are available for male and female programs.
Documentation for the
male and
female programs is also available.
