The American Joint Committee on Cancer (AJCC), in partnership with the CDC, has created software in the form of a dynamic link library (DLL) to help cancer registries collect data on stage of disease for cancers according to the TNM system of the AJCC. Content from AJCC's Cancer Staging System has been licensed for use by NPCR registries. The TNM 9th edition staging library is intended to support the AJCC 9th edition standard and is applicable for diagnosis years 2021 and later.
For access to the licensed versions of this DLL, contact firstname.lastname@example.org.
The Cancer Surveillance DLL has several primary functions:
The DLLs can be incorporated in cancer registry software programs to support standardized collection of TNM and other staging data.
The 9th edition of the Cancer Surveillance DLL has been implemented in both C++ and C# as 32-bit and 64-bit Windows DLLs.
Both DLLs are included in the release package, along with documentation, code files and wrappers, and sample programs.
Underlying contents are incorporated from AJCC's API and from SEER*RSA. Each release of the Cancer Surveillance DLL has an assigned version (one for C++, one for C#), plus the version of AJCC and SEER RSA that was used in the build.
