8th Edition Updates


 Invitation to Informational Webinar on the AJCC API for the 8th Edition


The American Joint Committee on Cancer (AJCC) is in the process of developing an Application Programming Interface to deliver the 8th Edition Cancer Staging System in electronic format.  The AJCC is excited to partner with easyDITA and Scriptorium on this project.

For the first time, the AJCC will be making the Cancer Staging System available in an electronic format for software vendors.

  • Focus on usability of software rather than accuracy of the AJCC content

  • Integrate once and maintain connection for all future versions of the AJCC Staging System

  • Take advantage of upcoming enhancements to content API in real-time

  • Benefit from the most accurate and up-to-date AJCC Staging System in your software

Conceptual Representation of the how the API will work for users.



As the AJCC moves to provide staging system content in this new format, we are seeking the input of all software vendors and developers. The AJCC hopes that vendors will welcome the opportunity to provide input early in the development of the API.

The AJCC hosted an informational webinar March 31, 2016 from 1:00-2:00pm Central Time.

The AJCC welcomes any advanced questions which can be addressed on the webinar. Please direct those questions to ajcc@facs.org with the subject line “AJCC API Webinar.”

At time mark 36:35, the 8th Edition Editor-In-Chief Dr. Mahul B. Amin took the podium and spoke on the 8th Edition progress and updates, “The Bridge from a Population Based to a More Personalized Approach.” Dr. Amin started his presentation with an overview of the vision, structure and implementation for 8th Edition along with a brief historical perspective of the AJCC and more importantly the Staging manual. The first edition was published in 1977 and Dr. Amin went through the subsequent staging manuals that followed. Amin spoke to the persistent challenges to TNM Staging: TNM does not meet needs of clinicians and patients, TNM largely limited to anatomic information and TNM must maintain anatomic base.

He then went into an overview of what has changed since the 7th edition including advances in molecular underpinnings of cancer, increased availability of high throughput testing, advances in informatics & computational biology, increased coordination in cancer care, maturing data, oncology therapies becoming more sophisticated and the globalization of cancer.


The vision for the 8th Edition will provide the definitive, comprehensive, proactive, evidence-based, contemporary, clinically relevant taxonomy of human neoplasia.


Through the past months, summer 2014, the editorial board has developed: Standardized chapter outline – will serve as a template for most chapters (except for non-TNM sites - CNS, lymphoma & leukemia) along with General staging rules to be used consistently in all chapters - proposed by Content Harmonization Core will be finalized by editorial board by Jan 1, 2015.


Dr. Amin closed with stating that the 8th Edition strategic and operational plans are ambitious but set in accordance with “high expectations” of the next upgrade of the AJCC system which has become synonymous with cancer prognostication, management, research and reporting


The work performed in past 18 months is nothing short of monumental and exemplifies team work at its best – thanks to the Executive Committee, the 8th Edition Editorial Board members & AJCC leadership and staff at the Chicago office.

 8th Edition Expert Panel Orientation


April 23rd, 2014

On Thursday, April 3rd, the Editorial Board, Expert Panel Chairs and Vice Chairs for the AJCC Cancer Staging System met in Chicago to discuss plans for the 8th Edition. Editor-in-Chief Mahul B. Amin, MD, FCAP presented his vision for the project to the group, which focuses on integration of molecular biomarkers for more accurate disease stratification and inclusion of all cancer specialties in the authoring process.






Chief among the orientation presentations was the Cancer Staging Content Transformation Project (CSCoT) - a content harmonization initiative by the AJCC to further enhance usability of the staging system by providing clearer staging rules and references for the 8th Edition and all future editions. The afternoon session focused on the Editorial Board Cores that will provide support for content harmonization, levels of evidence, integration of precision medicine, and data collection. The group capped off the day with a breakout session focusing on how AJCC can integrate personalized medicine into the TNM staging system.

 Introducing the AJCC 8th Edition Editorial Board and Expert Panel Leaders


February 20th, 2014
The AJCC is pleased to introduce the thought leaders of the AJCC Cancer Staging System, 8th Edition.

Led by Mahul B. Amin, MD, FCAP, the 15 member Editorial Board features representatives from each cancer specialty, and leaders of internal development “cores” – a new concept introduced by Dr. Amin.  These cores are tasked with harmonizing specific areas of staging system development, including:
  • Precision Medicine Core – focused on integrating non-anatomic prognostic factors into the staging system
  • Evidence Based Medicine and Statistics Core – focused on developing levels of evidence for changes and updates to the staging system
  • Content Harmonization Core – focused on harmonizing terms and concepts used in the staging system
  • Data Collection Core – focused on collaboration with the surveillance community to assure medical record access to and quality of 8th edition data elements
  • Professional Organization and Corporate Relationship Core – manages grants and contributions for development of the AJCC Cancer Staging System
  • Administrative Core – oversees the development process of the staging system
The 8th Edition will be authored by a team of 18 Expert Panels, each steered by a Chair and Vice Chair selected by the Editorial Board.  The composition of each expert panel strives to collaboratively harness the collective intelligence of the thought leaders for each disease site.  The membership represents diversity of thought and specialty; each panel's Chair and Vice Chair come from different organizations and represent different specialties.   
The full roster of Editorial Board members and Expert Panel leaders can be found here.
Formation of the full expert panels is underway and is expected to be completed by year-end.  
The 8th edition will be effective for all cancer cases recorded on or after January 1, 2017.  Visit our website for all 8th Edition Updates.  We look forward to a collaborative development process!
