Note 1 Leave Grade Post Therapy Clin (yc) blank when
- No neoadjuvant therapy
- Clinical or pathological case only
- Neoadjuvant therapy completed, no microscopic exam is done prior to surgery/resection of primary tumor
- There is only one grade available and it cannot be determined if it is clinical, pathological, post therapy clinical or post therapy pathological
Note 2 Assign the highest grade from the microscopically sampled specimen of the primary site following neoadjuvant therapy or primary systemic/radiation therapy.
Note 3 If there are multiple tumors with different grades abstracted as one primary, code the highest grade.
Note 4 The grading system for this chapter is based on histology
- Immature teratomas and serous carcinomas Use codes L, H, or 9. This include the following ICD-O-3 codes 8441/2, 8441/3, 8460/3, 8461/3, 8474/3, 9080/3
- All other histologies Code 1-3 if a nuclear grade is documented, otherwise code 9
- If your registry collects ovarian borderline tumors (/1), code “B” for grade
Note 5 G3 includes anaplastic.
Note 6 Code 9 (unknown) when
- Microscopic exam is done after neoadjuvant therapy and grade from the primary site is not documented
- Microscopic exam is done after neoadjuvant therapy and there is no residual cancer
- Grade checked “not applicable” on CAP Protocol (if available) and no other grade information is available
