| Guide for use: | Supplementary codes CODE 7 Unknown (test results not available) Use this code when the test has been performed but the results are not yet available for analysis. CODE 8 Not applicable (test not done) This code is used as a validation measure, to show that the reason for the lack of results is due to the test not being performed. | ||||||||

| Guide for use: | Where the pathologist has stated the test result in the conclusion of the pathology report as being positive, negative or equivocal this value should be coded. If the report does not specifically state the test result, this should be interpreted from the reported % nuclei stained positive. If => 1% of nuclei are reported as stained regardless of stain intensity (weak, intermediate or high/strong) the result is positive. If % nuclei stained is <1% the result is negative.

| Collection methods: | For cancer registries: Collection of this data item should only be from notification and pathology reports relating to initial diagnosis and not for recurrent or subsequent metastatic disease. Where there are multiple reports relating to the primary breast tumour (from different specimens), the 'most positive' value is chosen according to the following hierarchy: Positive > Equivocal > Negative> Test done but results not known > Test not done. If oestrogen receptor assay tests are completed for invasive tumours with an in situ component, use the values from the invasive tumour. Do not record oestrogen receptor values for in situ tumours. For multifocal tumours, use the oestrogen receptor value from the largest focus or from a metastatic deposit, e.g. Lymph node metastasis. A smaller focus that is ER positive may in fact be the source of a metastasis and in this setting the patient would derive benefit from the therapy offered as a result of hormone receptor positive status. | ||||||||
| Comments: | Hormone receptor status is an important prognostic indicator for breast cancer. The Australian Cancer Network Working Party established to develop guidelines for the pathology reporting of breast cancer recommends that hormone receptor assays be performed on all cases of invasive breast carcinoma. The report should include
