Study Shows Breast Cancer Vaccine To Be Safe

Topics: Breast Cancer

Researchers report that a vaccine designed to treat breast cancer appears to be safe in women with advanced disease and has shown signs of actually slowing down tumors. The new vaccine, called Neuvenge, targets her2/neu-positive breast cancer, which affects between 20 percent and 30 percent of breast cancer patients. Neuvenge is made using immune cells from the cancer patient, and makes use of immune system cells called CD4 helper T-cells.

... there is more than one target and more than one cancer that potentially will benefit from this form of therapy," he said. Other companies are also working on cancer vaccines.

The her2/neu protein is over-expressed, meaning it is over-active, in several tumors including breast, colorectal and ovarian cancer.

The vaccine is a therapeutic vaccine, meaning it stimulates an immune response to existing disease. The patient's T-cells are removed, "trained" to recognize the her2/neu protein, and then re-infused into the patient.
