8th Edition Implementation Project


January 1, 2018 is the new implementation date of the AJCC 8th Edition for cancer data collection.

The American Joint Committee on Cancer (AJCC) has been working closely with all of its member organizations throughout the development of the recently published 8th Edition Cancer Staging Manual.  The coordination of the implementation for a new staging system is critically important to ensure that all partners in patient care and cancer data collection are working in synchrony. 

In order to ensure that the cancer care community has the necessary infrastructure in place for documenting  8th Edition stage, the AJCC Executive Committee, in dialogue with the National Cancer Institute (NCI-SEER), Centers for Disease Control and Prevention (CDC-NPCR), the College of American Pathologists (CAP), the National Comprehensive Cancer Network (NCCN), the National Cancer Data Base (NCDB), and the Commission on Cancer (CoC), made the decision to delay the implementation of the 8th Edition Cancer Staging System to January 1, 2018.

Clinicians will continue to use the latest information for patient care, including scientific content of the 8th Edition Manual.   All newly diagnosed cases through December 31st, 2017 should be staged with the 7th edition.  The time extension will allow all partners to develop and update protocols and guidelines and for software vendors to develop, test, and deploy their products in time for the data collection and implementation of the 8th edition in 2018.

The AJCC is working together with all of its members as well as software vendors to make this transition as smooth as possible for the oncology community.  More communication will follow from the AJCC and the member organizations over the coming weeks.  Please visit this page for regular updates on the project, and share this link with your constituents: bit.ly/AJCCimplementation​.​
