PR (Progesterone Receptor) Summary

This input is used for staging


**Note 1:** Physician statement of PR (Progesterone Receptor) Summary status can be used to code this data item when no other information is available. **Note 2:** The result of the PR 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 PR is done on both, ignore the in situ results. * If PR is positive on an in situ component and PR is negative on all tested invasive components in the primary tumor, code PR as negative (code 0) * If in situ and invasive components present and PR 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 PR results. * Use the highest (positive versus negative) **Note 6:** In cases where there are multiple tumors with different PR 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 PR results from pre-treatment specimens, report the findings from post-treatment specimens. **Note 8:** If the patient is PR positive and node negative, a multigene test such as Oncotype Dx may be performed, in which case another PR 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
