Grade Pathological - Standard
**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
- 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
* 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
