Collaborative Stage Data Set - Revised 09/02/2010 FINAL
|Code||Description||Staging Basis 7||Staging Basis 6|
|0||Does not meet criteria for AJCC pathologic staging:|
Evaluation based on physical examination, imaging examination, or other non-invasive clinical evidence. No surgical resection done.
|1||Does not meet criteria for AJCC pathologic staging:|
Evaluation based on endoscopic examination, diagnostic biopsy, including fine needle aspiration biopsy, or other invasive techniques, including surgical observation without biopsy. No surgical resection done.
|2||Meets criteria for AJCC pathologic staging:|
Evidence derived from autopsy (tumor was suspected or diagnosed prior to autopsy). No surgical resection done.
|3||Either meets criteria for AJCC pathologic staging:|
A. 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.
B. No surgical resection done. Evaluation based on positive biopsy of highest T classification.
|5||Does 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).
|6||Meets 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.
|8||Meets criteria for autopsy (a) staging:|
Evidence from autopsy only (tumor was unsuspected or undiagnosed prior to autopsy)
|9||Unknown if surgical resection done|
Not assessed; cannot be assessed
Unknown if assessed
Not documented in patient record
