Which organization is the administrative sponsor of the AJCC?

• A. International Union Against Cancer
• B. Commission on Cancer
• C. National Cancer Database
• D. American College of Surgeons

Answer: (D)

Administrative leadership for the AJCC is provided by the American College of Surgeons. The AJCC operates under the umbrella of this professional surgical society, which handles its governance, resources, and coordination for developing and updating the cancer staging manuals used worldwide. The Commission on Cancer is a program within the American College of Surgeons that focuses on accrediting cancer programs, and the National Cancer Database is a registry created by ACS’s Commission on Cancer—both part of ACS but not the sponsor of the AJCC. The International Union Against Cancer is a separate international organization that collaborates on broader cancer-control efforts but does not administer the AJCC.
