Registrar Education

AJCC is dedicated to supporting cancer registrars in the transition to directly assigning AJCC TNM stage. ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​


 Staging Moments

​The Staging Moments® series offers succinct, contemporary case-based presentations following the cancer conference (tumor board) format of: symptom presentation; imaging work-up; and pathology diagnosis.  Clinical stage is assigned and used in discussing treatment options based on national guidelines. The series provides surgical and pathology findings to assign pathological or posttherapy /postneoadjuvant therapy stage.

New Eight Edition Staging Moments can be found here. ​

 Timing is Everything


Stage Classifications c p yc yp.jpg 

Timing is the key to AJCC clinical and pathologic staging.  AJCC stage classification timeframes match the points in time in a patient’s care based on their treatment.  All patients undergoing diagnostic work-up for cancer are assigned clinical staging.  If the patient has surgical treatment, the managing physician assigns pathologic staging.  If the patient receives systemic or radiation therapy, the managing physician assigns posttherapy staging.

The graphic represents the patient care continuum with treatment choices and the resulting stage classifications.  The arrows indicate the starting and ending points for information included in that stage.​
