Created the first working vaccine against breast cancer
Researchers at the University of Pennsylvania
Were able to get a unique vaccine from cells of the patient to cope with breast cancer, reports The Telegraph. Tests have shown that 85% of women with ductal carcinoma were protected from the disease, even after four years after vaccination.
Vaccine was tested in 27 patients. They researchers took special white blood cells. Specially treated cells in the laboratory, then the immune system can recognize cancer cells as a pathogen and attack them.
Each patient made four-week injection personally prepared vaccine. Two weeks later had surgery to remove residual tumor. Then the researchers compared tissue samples taken before and after vaccination. The verdict was that 20% of patients had no signs of cancer, that is, the immune system cope with the cancer itself.
The remaining vaccine will get rid of the body of damaging protein HER2/neu or reduce the concentration of 20%. According to the researchers, in the near future to begin the second part of the test. However, we can already say that vaccination is likely to be more effective against early, localized stage cancer.
Influencing HER2/neu, agent necessary for the survival of cancer, get rid of the disease for several years. The scientists also stress the lack of serious side effects. True, patients recorded a general malaise, pain at the injection site, chills, fever and headaches.
