When a cancer is HER2-positive, it means that the cancer cells make too much HER2 protein, which can cause tumors to grow more rapidly than with other forms of breast cancer. Drugs that target the HER2 proteins are the primary treatment for this type of breast cancer, given along with chemotherapy.
What is HER2 positive breast cancer and how is it treated?
HER2 positive breast cancers tend to be more aggressive, and in earlier years had a poorer prognosis. In 1998 the first medication to directly target HER2 was approved. This medication is Herceptin (trastuzumab).
How does ACTH kill cancer cells?
How ACTH Works. Both doxorubicin and cyclophosphamide (AC) damage the DNA inside cancer cells so they can’t divide, which causes them to die. With doxorubicin, the damage stops the cancer cells from dividing and causes them to die. Cyclophosphamide stops cancer cells from reproducing.
What is ACTH Herceptin and carboplatin chemotherapy?
Herceptin plus the chemotherapy medicines Adriamycin, Cytoxan (chemical name: cyclophosphamide), and Taxotere (chemical name: docetaxel); this combination is called ACTH Herceptin plus the chemotherapy medicines carboplatin (brand name: Paraplatin) and Taxotere; this combination is called CTH
When is a dual-targeted HER2 approach typically used in breast cancer?
A dual-targeted HER2 approach is typically used if there are no contraindications. However, what remains to be determined is whether adding a newer HER2-targeted therapy would increase progression-free survival, or whether immunotherapy would help in overcoming the resistance to HER2-targeted therapies.

What is the best treatment for HER2 breast cancer?
Trastuzumab is given intravenously (with an IV) weekly or every 3 weeks. As an adjuvant therapy, one year of treatment of treatment is typical. Multiple studies show that trastuzumab can dramatically improve survival. In fact, trastuzumab-based treatments for HER2+ breast cancer are considered the gold standard.
What is the standard of care for HER2-positive breast cancer?
“For most patients with stage I HER2-positive breast cancer, taxane plus trastuzumab remains the standard of care, with excellent 7-year disease-free survival rates of about 93%. For most stage II to III HER2-positive breast cancers, trastuzumab/pertuzumab-based therapy has become a standard option.
What does trastuzumab do to HER2?
Herceptin works by blocking the effects of HER2 and encouraging the immune system (the body's natural defences) to attack and kill the cancer cells.
What chemo drugs are used for HER2-positive breast cancer?
HER2-positive tumors If a tumor is HER2-positive, the HER2-targeted therapy drug trastuzumab (Herceptin) is included in the chemotherapy regimen. Sometimes other drugs that target HER2 are used. Pertuzumab (Perjeta) can be combined with trastuzumab, and neratinib (Nerlynx) can be given after trastuzumab.

How does Herceptin bind to HER2?
Herceptin binds to the juxtamembrane region of HER2 on the C-terminal portion of subdomain IV. The interaction formed by Herceptin and HER2 is mediated by three regions on HER2 that form three loops: residues 557-561 (loop 1), 570-573 (loop 2), and 593-603 (loop 3).
What is HER2-targeted therapy?
Anti-HER2 therapies (also called HER2 inhibitors or HER2-targeted therapies) are a class of medicines used to treat all stages of HER2-positive breast cancer, from early-stage to metastatic. Metastatic breast cancer is cancer that has spread to other parts of the body away from the breast, such as the bones or liver.
Why is Perjeta given before Herceptin?
Jan 3, 2020. Updated results from the APHINITY trial confirmed that adding Perjeta (chemical name: pertuzumab) to Herceptin (chemical name: trastuzumab) and chemotherapy after surgery for early-stage HER2-positive breast cancer reduces the risk of recurrence (the cancer coming back) and slightly improves survival.
What are the chances of HER2-positive breast cancer returning?
