HER Story Patient Ambassadors

Every person who has HER2+ breast cancer is unique, and no cancer treatment works for every person. Your experience may be different from those of the women who participated in the clinical trials. Further, because of the aggressive nature of HER2+ breast cancer, the status of these women may change over time.

Understanding breast cancer can be challenging. Learning about the different stages of breast cancer and the complicated elements of your pathology report are only part of it. You also have to understand your treatment options, the right questions to ask your healthcare providers, and what you can do to understand your condition.

We want you to know that you are not alone in this journey. Created and provided by Genentech BioOncology, the Herceptin HER Story Patient Ambassador Program connects you with other women who are fighting breast cancer each and every day. When you connect with other women fighting breast cancer, you share the journey and may find support.

The program features women from across the country who have or are receiving Herceptin for their HER2+ breast cancer. Each woman is reaching out and sharing her story to help you learn from the experiences she had along the way.

As part of this informational program, a Genentech oncology nurse specialist shares important information about breast cancer, treatment options with a focus on Herceptin, and current resources. The specialist will also be able to answer general questions you may have about breast cancer and typical treatment options.

Who is Herceptin for?

Herceptin is approved for the adjuvant treatment of HER2-overexpressing, node-positive or node-negative (ER/PR-negative or with one high-risk feature)† breast cancer. Herceptin can be used several different ways:

  • As part of a treatment regimen including doxorubicin, cyclophosphamide, and either paclitaxel or docetaxel
  • With docetaxel and carboplatin
  • As a single agent following multi-modality anthracycline-based therapy

Herceptin in combination with paclitaxel is approved for the first-line treatment of HER2-overexpressing metastatic breast cancer. Herceptin as a single agent is approved for treatment of HER2-overexpressing breast cancer in patients who have received one or more chemotherapy regimens for metastatic disease.

† High-risk is defined as ER/PR positive with one of the following features: tumor size >2 cm, age <35 years, or tumor grade 2 or 3.

What important safety information should I know about Herceptin?

Herceptin treatment can result in heart problems, including those without symptoms (reduced heart function) and those with symptoms (congestive heart failure). The risk and seriousness of these heart problems were highest in people who received both Herceptin and a certain type of chemotherapy (anthracycline). Your doctor will stop or strongly consider stopping Herceptin if you have a significant drop in your heart function.

You should be monitored for decreased heart function before your first dose of Herceptin, and frequently during the time you are receiving Herceptin and after your last dose of Herceptin. If you must permanently or temporarily stop Herceptin due to heart problems, you should be monitored more frequently. In one study with Herceptin and certain types of chemotherapy, an inadequate blood supply to the heart occurred.

Some patients have had serious infusion reactions and lung problems; fatal infusion reactions have been reported. In most cases, these reactions occurred during or within 24 hours of receiving Herceptin. Your Herceptin infusion should be temporarily stopped if you have shortness of breath or very low blood pressure. Your doctor will monitor you until these symptoms go away. If you have a severe allergic reaction, swelling, lung problems, inflammation of the lung, or severe shortness of breath, your doctor may need to completely stop your Herceptin treatment.

Worsening of low white blood cell counts associated with chemotherapy has also occurred.

Herceptin can cause low amniotic fluid levels and harm to the fetus when taken by a pregnant woman.

The most common side effects associated with Herceptin were fever, nausea, vomiting, infusion reactions, diarrhea, infections, increased cough, headache, fatigue, shortness of breath, rash, low white and red blood cells, and muscle pain.

Because everyone is different, it is not possible to predict what side effects any one person will have. If you have questions or concerns about side effects, talk to your doctor.
