The NCDB Participant Use Data File (PUF) is a Health Insurance Portability and Accountability Act (HIPAA)-compliant data file containing cases submitted to the Commission on Cancer’s (CoC) National Cancer Data Base (NCDB). The PUF contains de-identified patient level data that do not identify hospitals, health care providers, or patients as agreed to in the Business Associate Agreement that each CoC-accredited program has signed with the American College of Surgeons. The PUFs are designed to provide investigators associated with CoC-accredited cancer programs with a data resource they can use to review and advance the quality of care delivered to cancer patients through analyses of cases reported to the NCDB. NCDB PUFs are only available through an application process to investigators associated with CoC-accredited cancer programs.
The NCDB is extending the opportunity to investigators at CoC-accredited cancer programs to apply for a PUF on a semi-annual basis
- The 2015 initial application period was January 5–February 6, 2015, for any investigator from a CoC-accredited cancer program.

Interested investigators must have the designated role of “NCDB PUF Applicant” in order to access the NCDB PUF Application Manager; if not, they will be blocked without this role assignment.
