NAACCR XML: Tumor.her2OverallSummary
HER2 Overall Summary is a summary of results from HER2 testing.
This data item is required for prognostic stage grouping in AJCC 8th edition, Chapter 48, Breast. It was previously collected as Breast, CS SSF # 15.Experts recommend that every invasive breast cancer be tested for the presence of HER2 because anti-HER2 treatments are highly effective for these tumors.
HER2 overall summary will be collected for Esophagus and Esophagogastric Junction and Stomach for cases diagnosed 1/1/21+ because NCCN guidelines recommend HER2 testing at time of diagnosis if patients are documented or suspected of having metastatic disease. HER2 monoclonal antibodies may be added to chemotherapy for patients with HER2 positive disease.
