Anti-cancer VirusAnti-cancer Virus, A cancer virus, which targets and injected into the blood, selectively targets cancer cells throughout the body, leaving only healthy tissue, according to the BBC. It has been called a medical first, and researchers say the discovery could “real change” therapy a day.

The small trial in 23 patients appeared in the journal “Nature.”

Although the use of viruses to fight cancer is not a new concept, usually must be injected into tumors. However, the new engineered viruses injected into the blood and only tumors of the attacks.

According to the BBC, scientists modified virus vaccine and called JX-594. Previously, the vaccine virus was known to be used to develop a vaccine against smallpox.

For the study, researchers injected different doses in the blood of 23 patients with cancer that had spread to multiple organs. Of the eight patients who received the highest dose, seven had viral replication in tumors but not in healthy tissue, according to the BBC.

Professor John Bell, lead researcher and University of Ottawa, told the BBC: “We are very happy because this is the first time in medical history that a viral therapy has been shown to be repeated constantly and selectively in the cancerous tissue after intravenous infusion of human beings. Intravenous administration is crucial for the treatment of cancer because it allows us to target tumors throughout the body rather than just those who can directly inject “.

The virus does not cure cancer, but it did prevent the growth of tumor in six patients over a period of time. The study was designed to test the safety of the virus, so that patients received a single dose of the virus.

However, researchers believe the virus can be used in higher concentrations to deliver treatments directly to cancer cells.
