Grade Post Therapy Clin (yc) (Parathyroid)
Organization | Field Name | ID# | ID Name | Required |
---|---|---|---|---|
KCR | Grade Post Therapy Clin (yc) | 30141 | GradePostTherapyClin | yes |
SEER | Grade Post Therapy Clin (yc) | gradePostTherapyClin | yes |
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 Codes L and H take priority over A-D.
Note 5 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
Code | Description |
---|---|
L | LG: Low grade: round monomorphic nuclei with only mild to moderate nuclear size variation, indistinct nucleoli, and chromatin characteristics resembling those of normal parathyroid or of adenoma |
H | HG: High grade: more pleomorphism, with a nuclear size variation greater than 4:1; prominent nuclear membrane irregularities; chromatin alterations, including hyperchromasia or margination of chromatin; and prominent nucleoli. High-grade tumors show several discrete confluent areas with nuclear changes |
A | Well differentiated |
B | Moderately differentiated |
C | Poorly differentiated |
D | Undifferentiated, anaplastic |
9 | Grade cannot be assessed (GX); Unknown |
