Comments
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.

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
- the percentage of nuclei staining positive and the predominant staining intensity (low, medium, high) and
- a conclusion as to whether the assay is positive or negative.
