CodeDescriptionStaging Basis
0Does not meet criteria for AJCC pathologic staging:
           

No surgical resection done.  Evaluation based on physical examination, imaging examination, or other non-invasive clinical evidence.  No autopsy evidence used.
c
1Does not meet criteria for AJCC pathologic staging:

No surgical resection done.  Evaluation based on endoscopic examination, diagnostic biopsy, including fine needle aspiration biopsy, or other invasive techniques, including surgical observation without biopsy.  No autopsy evidence used.
c
2Meets criteria for AJCC pathologic staging:

No surgical resection done, but evidence derived from autopsy (tumor was suspected or diagnosed prior to autopsy)
p
3Either criteria meets AJCC pathologic staging:

Surgical resection performed WITHOUT pre-surgical systemic treatment or radiation
OR surgical resection performed, unknown if pre-surgical systemic treatment or radiation performed
AND Evaluation based on evidence acquired before treatment, supplemented or modified by the additional evidence acquired during and from surgery, particularly from pathologic examination of the resected specimen.

No surgical resection done.  Evaluation based on positive biopsy of highest T classification.
p
5Does not meet criteria for AJCC y-pathologic (yp) staging:

Surgical resection performed AFTER neoadjuvant therapy and tumor size/extension based on clinical evidence, unless the pathologic evidence at surgery (AFTER neoadjuvant) is more extensive (see code 6).
c
6Meets criteria for AJCC y-pathologic (yp) staging:

Surgical resection performed AFTER neoadjuvant therapy AND tumor size/extension based on pathologic evidence,  because pathologic evidence at surgery is more extensive than clinical evidence before treatment.
yp
8Meets criteria for autopsy (a) staging:

Evidence from autopsy only (tumor was unsuspected or undiagnosed prior to autopsy)
