New test for oral cancer detection

Researchers are on the verge of developing a new test for oral cancer that could be done by using a brush to collect cells from a patient's mouth. Scientists from the University of Sheffield would develop the new method that could provide an accurate diagnosis in less than 20 minutes for lesions where there is a suspicion of oral cancer.

The new test would involve removing cells with a brush, placing them on a chip, and inserting the chip into the analyzer, leading to a result in 8-10 minutes. This will have a number of benefits including cutting waiting times and the number of visits, and also cost savings for the NHS.


The team led by Professor Martin Thornhill has begun carrying out clinical trials on patients at Charles Clifford Dental Hospital for two years to perfect the technology and make it as sensitive as possible.

If oral cancer is detected early, the prognosis for patients is excellent, with a five-year survival rate of more than 90 percent.

The nano-bio-chips are disposable and slotted like a credit card into a battery-powered analyzer. A brush-biopsy sample is placed on the card and micro fluidic circuits wash cells from the sample into the reaction chamber.
