Collaborative Stage for TNM 7 - Revised 11/12/2010 [ Schema ]
CS Site-Specific Factor 15
HER2: Summary Result of Testing
- Note 1: The summary of the results of the Immunohistochemistry (IHC), Fluorescent In Situ Hybridization (FISH), Chromogenic In Situ Hybridization (CISH), or other/unknown Human Epidermal Growth Factor Receptor 2 (HER2) test is recorded here. This variable is based on CS Site-Specific Factors 9, 11, 13, and 14.
- Note 2: If both an IHC and a gene-amplification test (FISH or CISH) are performed, record the result of the gene-amplification test in this field. However, if the gene-amplification test is given first and the result is borderline or equivocal and an IHC test is done to clarify these equivocal results, code the result of the IHC test.
- Note 3: If the results of one test are available, and it is known that a second test is performed but the results are not available, use code 997.
