Grade Pathological - Standard
Notes
Note 1: Grade Pathological must not be blank.
Note 2: Assign the highest grade from the primary tumor.
Note 3: If there are multiple tumors with different grades abstracted as one primary, code the highest grade.
Note 4: Use the grade from the clinical work up from the primary tumor in different scenarios based on behavior or surgical resection
- Behavior
- Tumor behavior for the clinical and the pathological diagnoses are the same AND the clinical grade is the highest grade
- Tumor behavior for clinical diagnosis is invasive, and the tumor behavior for the pathological diagnosis is in situ
- Surgical Resection
- Surgical resection is done of the primary tumor and there is no grade documented from the surgical resection
- Surgical resection is done of the primary tumor and there is no residual cancer
- No surgical resection
- Surgical resection of the primary tumor has not been done, but there is positive microscopic confirmation of distant metastases during the clinical time frame
Note 5: Code 9 (unknown) when
- Grade from primary site is not documented
- Surgical resection is done after neoadjuvant therapy and grade from the primary site is not documented and there is no grade from the post therapy clinical work up
- Surgical resection is done after neoadjuvant therapy and there is no residual cancer and there is no grade from the post therapy clinical work up
- No resection of the primary site (see exception in Note 4, Surgical resection, last bullet)
- Neo-adjuvant therapy is followed by a resection (see Grade Post Therapy Path (yp))
- Grade checked “not applicable” on CAP Protocol (if available) and no other grade information is available
- Clinical case only (see Grade Clinical)
- There is only one grade available and it cannot be determined if it is clinical, pathological, post therapy clinical or post therapy pathological
