Note 1 Physician statement of HER2 Overall Summary can be used to code this data item when no other information is available.
Note 2 The result of the HER2 test performed on the primary breast tissue is to be recorded in this data item.
Note 3 Results from nodal or metastatic tissue may be used ONLY when there is no evidence of in situ or invasive carcinoma in the primary tumor.
Note 4 In cases where there are invasive and in situ components in the primary tumor and HER2 is done on both, ignore the in situ results.
- If HER2 is positive on an in situ component and HER2 is negative on all tested invasive components in the primary tumor, code HER2 as negative (code 0)
- If in situ and invasive components present and HER2 only done on the in situ component in the primary tumor, code unknown (code 9)
Note 5 In cases where there is a single tumor with multiple biopsies and/or surgical resection with different HER2 results.
- Use the highest (positive versus negative)
Note 6 In cases where there are multiple tumors with different HER2 results, code the results from the largest tumor size (determined either clinically or pathologically) when multiple tumors are present.
- Do not use specimen size to determine the largest tumor size
Note 7 If neoadjuvant therapy is given, record the assay from tumor specimens prior to neoadjuvant therapy.
- If neoadjuvant therapy is given and there are no HER2 results from pre-treatment specimens, report the findings from post-treatment specimens
Note 8 If the patient is HER2 positive and node negative, a multigene test such as Oncotype Dx may be performed, in which case another HER2 test will be performed. Do not record the results of that test in this field.
- Record only the results of the test which made the patient eligible to be given the multigene test
Note 9 HER2 is not routinely done on pure in situ tumors (behavior /2); however, if you have an in situ tumor and there are HER2 results, go ahead and record it. Otherwise code 9.
