US researchers announce the development of a "personal vaccines" against cancer

US researchers said, they were able to develop vaccines specially prepared to combat the unique genetic mutations in patients with skin cancer, which opens the way for the production of vaccines "personal" for a number of cancers such as lung, bladder, colon and rectal cancer.

The researchers conducted at the Faculty of Medicine, University of Washington clinical trials on three patients with skin cancer, has been producing vaccines for them specifically, and show that these vaccines have succeeded in stimulating the immune system to fight cancer, indicating that the preliminary results of the research represents an important step in the way of producing vaccines "personal" (each person separately) to the fight against cancer, and published their findings in the journal "Science" scientific.

The idea of ​​personal vaccines, according to the research team, the genetic mutation analysis, to predict new signals carried by cancer cells in patients, then a computer program that scans those signals to determine the best goals of the injected vaccine.

The researchers said that he can remove the tumors, skin cancer if detected early enough, and produced vaccines for the three patients with tumors in advanced stages of 2013, and after receiving the vaccine, samples were taken from the blood of three patients once a week for 4 months, the researchers found that the vaccine successfully Thiv in T cells, which play a key role in the immune system to fight tumors.

According to research team leader Professor "Gerald Lynette" at the University of Washington: "Our team has a great deal of encouragement, because of the immune-oriented system response against melanoma cells of the three patients," he said: "Our results are still preliminary, has proven its safety and effectiveness in the long short, and there is a need for further testing to monitor its effectiveness in the long term, and we believe that vaccines have therapeutic potential. "

He pointed out that cancer vaccines to stimulate the immune system approach can be directed to treat mutations lung cancers, bladder, colon and rectum, which is characterized by high rates of mutations, similar to genetic mutations of skin cancer.

According to the World Health Organization, the cancer, is one more cause of death around the world, the cause of this disease in the death of 7.6 million people, equivalent to about 13% of all deaths in the world's population, in 2008 alone, highlighting the lung, stomach and liver cancers. , colon, breast and cervical behind most of the deaths that occur every year due to cancer.
