Grade Post Therapy Path (yp)

Notes

**Note 1:** Leave Grade Post Therapy Path (yp) blank when * No neoadjuvant therapy * Clinical or pathological case only * There is only one grade available and it cannot be determined if it is clinical, pathological, post therapy clin or post therapy path **Note 2:** Grade is applicable for the follicular lymphomas only (9690/3, 9691/3, 9695/3, 9698/3). For all other lymphoma histologies, code 9. **Note 3:** Assign the highest grade from the resected primary tumor assessed after the completion of neoadjuvant therapy. **Note 4:** If there are multiple tumors with different grades abstracted as one primary, code the highest grade. **Note 5:** Follicular lymphoma grade is based on the absolute number of centroblasts per high-power (40 x objective, 0.159 square mm) microscopic field (HPF). **Note 6:** Code 9 (unknown) when * Surgical resection is done after neoadjuvant therapy and grade from the primary site is not documented * Surgical resection 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
