AJCC Staging 8th Edition Highlights

AJCC Staging 8th Edition Highlights

Several primary sites that have under gone significant changes with the implementation of the 8th Edition of AJCC Staging manual. I have included only a few key changes to remind you that it is very important to use the AJCC manual (rather than software pull-down menus, slides from presentations, or other short cuts) to identify and record any elements required for staging. The best way to learn is directly from the source!

  • Breast:
    • Prognostic staging will require T,N,M; grade, HER2; and estrogen and progesterone status.
    • Genomic profiles will also factor into the stage.
  • Prostate:
    • Pathologic disease is now considered T2 and is no longer sub classified by extent of disease or laterality.
    • Tumor Grade includes both the Gleason Score and the grade group
    • The prognostic stage group III includes organ-confined disease based on PSA and Gleason/grade group
    • Head and Neck:
    • New staging model for Human Papilloma Virus (HPV) associated oropharynx cancer
    • Tumor staging for oral cavity, nasopharynx and cutaneous Squamous and basal cell carcinoma
    • Change in classification of unknown primary for head and neck cancer
    • Expanded staging for nodal disease
    • Restaging for nasopharynx will include (+/-) Epstein-barr virus (EBV)
    • Restaging for orpharynx will include (+) HPV
    • Restaging for oropharynx and hypopharynx (-) HPV
