NAACCR XML: Tumor.her2IshDualProbeRatio




Description
HER2 in situ hybridization (ISH) Dual Probe Ratio is the summary score for HER2 testing using a dual probe. The test will report results for both HER2 and CEP17, the latter used as a control. The HER2/CEP17 ratio is reported.
Rationale
HER2 ISH Dual Probe Ratio is a Registry Data Collection Variable in AJCC. It is a new data item for cases diagnosed 1/1/2018+.
Codes

    
        
            0.0-99.9
            Ratio of 0.0 to 99.9
        
        
            XX.2
            Less than 2.0
        
        
            XX.3
            Greater than or equal to 2.0
        
        
            XX.7
            Test ordered, results not in chart
        
        
            XX.8
            Not applicable: Information not collected for this case

                (If this item is required by your standard setter, use of code XX.8 will result in an edit error.)
            
        
        
            XX.9
            Not documented in medical record

                Results cannot be determined (indeterminate)
