Left ventricular systolic function in HER2/neu negative breast cancer patients treated with anthracycline chemotherapy: a comparative analysis of left ventricular ejection fraction and myocardial strain imaging over 12 months. HER2 Mutation Status in Japanese Patients with HER2-negative Breast Cancer. We analyzed 286 HER2-negative breast cancers including 13 invasive lobular carcinomas. Among the 286 patients, two patients (0.7%) were found to have HER2 mutations, I767M and D769Y (Figs 1 and 2, respectively). Reverse sequencing also confirmed these results.

If the score is 2+, it's considered borderline. A score of 3+ is considered HER2-positive. If the IHC test results are borderline, it’s likely that a FISH test will be done on a sample of the cancer tissue to determine if the cancer is HER2-positive. If the IHC result is 0 or 1+, the cancer is considered HER2-negative. These cancers do not respond to treatment with drugs that target HER2. If the IHC result is 3+, the cancer is HER2-positive. These cancers are usually treated with drugs that target HER2.

Grad 0-1 definieras som HER2 negativ, vid grad 2+ krävs komplettering med in situ hybridiseringsteknik (ISH) för att säkerställa att genamplifiering av HER2 föreligger (FISH, CISH eller SISH test).
