Patients to be given “100% accurate” 10-minute cancer test
“We need less than one drop of saliva and we can turn the test around in 10 minutes. It can be done in a doctor’s office while you wait,” David Wong, professor of oncology at California State University, said at the American Association for the Advancement of Science annual meeting in Washington.
Saliva can be used for the test as it is possible to spot tumor DNA in bodily fluids, he explained.
The team came up with the idea after they found out that saliva contained fragments of the genetic messenger molecule RNA linked to cancer.
“If there is circulating signature of a tumor in a person’s blood or saliva, this test will find it,” Professor Wong said, The Telegraph reported.
It is possible to receive a diagnosis as early as the tumor develops, he stressed, adding that the test is very simple and could be carried out anywhere, even at home.
“The advantage of our technology is that it is non-invasive. If you have a credible early screening risk assessment technology that people can use on their own or at dentists’ office or pharmacists – that’s the key, early detection,” Wong said.
Moreover, the diagnosis is 100 percent accurate, the scientist said.
The same cannot be said about current cancer tests. To detect cancer the traditional way, scientists have to take a biopsy and sequence a tumor. This method only allows doctors to monitor the spread of cancer, but cannot be used for an initial test.
Clinical trials on lung cancer patients are expected to be launched later this year to check the validity of the new test. The test also needs to be approved by the Food and Drug Administration in America.
The scientist hopes the test would be fully implemented in Britain by the end of the decade and would be used for other forms of cancer, such as oral cancer.
A therapy that retrains the body’s immune system to fight cancer has provoked excitement after more than 90% of terminally ill patients reportedly went into remission.
White blood cells were taken from patients with leukaemia, modified in the lab and then put back.
But the data has not been published or reviewed and two patients are said to have died from an extreme immune response.
Experts said the trial was exciting, but still only “a baby step.”
The news bubbled out of the American Association for the Advancement of Science’s annual meeting in Washington DC.
The lead scientist, Prof Stanley Riddell from the Fred Hutchinson Cancer Research Centre in Seattle, said all other treatments had failed in these patients and they had only two-to-five months to live.
He told the conference that: “The early data is unprecedented.”
detection is one thing..prevention and a cure is another..i hope the test works 100% of the time..but nothing is perfect..
