When the AJCC embarked on updating the AJCC Cancer Staging Manual, we knew that we would have to think
beyond the book, with an eye toward continuously improving content throughout
the life of the edition.
The delay
of implementation to January 1, 2018 has given AJCC an opportunity to work
with the surveillance community, the pathology community, and clinical decision
support software developers in ways we never have before. In the era of
electronic decision making, the level of scrutiny is higher; we are learning
more about how the content is applied in different use cases beyond the human
reader. Collaborating with these groups in real time has allowed us to take an
extra critical look at our content and make improvements and clarifications
that will help all audiences.
This highly analytical effort has resulted in a greater
number of updates and errata than in past editions, and we are committed to
communicating them transparently.
This site contains important updates and errata identified in the first printing of the AJCC Cancer Staging Manual, 8th Edition, and are effective for hard copy manuals purchased from September 2016 to February 2018. This list does not include typographical errors. If you have identified any issues not listed here, please email ajcc@facs.org.
To make this list more useful, we have divided the updates
and errata into four levels of significance:
- Critical Changes. Change is critical for accurate staging. Includes changes to TNM categories,
criteria, or prognostic stage groups.
- Histology/Topography. Corrections and
additions made to histology or topography codes.
- Clarification. Clarification of concepts in text or definitions
that does not affect staging.
- Omission. Error of omission that does not affect staging.
