An
engineered virus, injected into the blood, can selectively target cancer
cells throughout the body in what researchers have labelled a medical
first. The virus attacked only tumours, leaving the healthy tissue
alone, in a small trial on 23 patients, according to the journal Nature.
Researchers said the findings could one day "truly transform"
therapies. Cancer specialists said using viruses showed "real promise".
Using viruses to attack cancers is not a new concept, but they have
needed to be injected directly into tumours in order to evade the immune
system. The virus, named JX-594 ... was injected at different doses
into the blood of 23 patients with cancers which had spread to multiple
organs in the body. Prof John Bell, lead researcher and from the
University of Ottawa, said: "We are very excited because this is
the first time in medical history that a viral therapy has been shown
to consistently and selectively replicate in cancer tissue after
intravenous infusion in humans. Intravenous delivery is crucial for
cancer treatment because it allows us to target tumours throughout the body as opposed to just those that we can directly inject."
