METASTATIC BREAST CANCER

About Breast Cancer
Breast cancer happens when cells in the breast tissue divide and grow in an uncontrolled manner, becoming a cancerous ("malignant") tumor. About 20% of breast cancers start in the glands that produce milk, also called "lobules." About 80% start in the milk passages that connect the lobules and the nipple, called "ducts." Cancerous tumors in the breast usually grow very slowly. By the time one is large enough to be felt as a lump, it may have been growing for as long as ten years.¹

In 2007, about 178,000 women in the United States had invasive breast cancer.²

Fortunately, breast cancer death rates are going down, probably thanks to earlier diagnosis and improved treatment. But breast cancer is the most common cancer among women in the United States, other than skin cancer — and is the second leading cause of cancer death in women, after lung cancer. There is a 1 in 8 chance of a woman having invasive breast cancer some time during her life, while the chance of dying from breast cancer is about 1 in 35.²

Right now there are about 2.5 million breast cancer survivors in the United States.²

Two Types of Breast Cancer
There are two kinds of breast cancer, "invasive" breast cancer and "non-invasive" cancer.³ GEMZAR in combination with the chemotherapy drug paclitaxel is used to treat the metastatic, invasive form.

Your Metastatic Breast Cancer Journey
Facing a diagnosis of metastatic breast cancer is not easy. Like any person living with cancer, you are probably facing situations you never had to deal with before. And it is understandable if you are concerned about the new journey that lies ahead. But by working together with your healthcare team — asking questions and exploring your treatment options — you can take back some control.

GEMZAR in combination with paclitaxel is approved by the Food and Drug Administration for the first-line treatment of patients with metastatic breast cancer after they have received another type of chemotherapy called an anthracycline, unless their medical condition did not allow them to receive an anthracycline.

This section explores the two types of breast cancer. Learn how GEMZAR can help treat first-line metastatic breast cancer when used in combination with paclitaxel, another chemotherapy drug. You can also find information about side effects, and answers to frequently asked questions.

About GEMZAR

GEMZAR is indicated in combination with cisplatin (another type of chemotherapy) for the first-line treatment of patients with locally advanced (stage IIIA or stage IIIB) or metastatic (stage IV or cancer that has spread) non-small cell lung cancer for whom surgery is not possible.

GEMZAR is indicated in combination with carboplatin (another type of chemotherapy) for the woman with ovarian cancer that has returned at least 6 months after the patient had finished platinum-based therapy.

GEMZAR in combination with paclitaxel is approved by the FDA for the first-line treatment of patients with metastatic breast cancer after they have received another type of chemotherapy called an anthracycline, unless their medical condition did not allow them to receive an anthracycline.

GEMZAR is indicated as a single agent (given alone) as the first-line treatment for patients with locally advanced (stage II or stage III when surgery is not an option) or metastatic (stage IV) adenocarcinoma of the pancreas. GEMZAR is also indicated for patients previously treated with 5-FU (another type of chemotherapy).
