The last update of the manual version, the eighth edition\n                    <jats:italic>AJCC Cancer Staging Manual<\/jats:italic>\n                    , went into use on January 1, 2018. The AJCC has since restructured and updated its processes for curating, analyzing, and publishing updates to the TNM staging system. All AJCC staging\u2010related data are now housed on its new application programming interface. Consequently, the subsequent AJCC TNM staging updates are now published electronically as protocols and are released by disease sites. The protocol for carcinoma of the vulva, AJCC version 9, is now published. The new TNM vulvar cancer staging was validated using the American College of Surgeons\u2019 National Cancer Data Base. This article highlights the changes to the new AJCC TNM staging protocol for carcinoma of the vulva; these changes align with the 2021 International Federation for Gynecology and Obstetrics staging. The most important of the changes are: (1) a new method for depth of invasion measurement, (2) the addition of a new T subcategory\u2014T4, (3) redefined N subcategories, and (4) an increased number of M subcategories with the addition of\n                    <jats:italic>clinical<\/jats:italic>\n                    to all M subcategories.\n
