AJCC API Version 9 Effective January 2021

The American Joint Committee on Cancer (AJCC) is making an important content update to the AJCC API to be implemented beginning January 1, 2021.

The content update will be made available July 31, 2020 to all licensed users of the AJCC API. The update includes the new version 9 (v09.00.00) Cancer Staging System for Cervix Uteri. The version 9 content shall replace the current 8th Edition Cervix Uteri content effective January 1, 2021. The AJCC will be contacting licensees of the API directly with additional details on accessing the updated Cervix Uteri content.

Additional disease sites will be updated to version 9 of the Cancer Staging System in the coming years on an annual release schedule, with changes going into effect January 1 of the following year. As each disease is updated, the associated TNM definition and staging information will be available through AJCC API for licensees.

The complete version 9 Cervix Uteri content, including tables, notes, and illustrations will be available for end users later this year. Physicians and other users of the AJCC content will be able to purchase an electronic version of the new Cervix content to supplement the information provided in their software. Details on purchasing this content will be made available later this summer.
