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.
