Researchers Develop Quick, Easy Test To Detect Cancer From Blood



Australian researchers on Wednesday said they had developed a quick and easy test to detect cancer from blood or biopsy tissue, pointing to new approaches to patient diagnoses through simple devices like mobile phones.

One of the researchers, Dr Abu Sina, said: “The University of Queensland team discovered a unique DNA nanostructure that appears to be common to all cancers.

“This unique nano-scaled DNA signature appeared in every type of breast cancer we examined, and in other forms of cancer including prostate, colorectal and lymphoma.

“The levels and patterns of tiny molecules called methyl groups that decorate DNA are altered dramatically by cancer- these methyl groups are key for cells to control which genes are turned on and off.

“The new test involves a tool that is able to help analyse the pattern changes at the whole genome level within minutes.’’

According to a statement by the researchers, the technology has proved to be up to 90 per cent accurate in tests involving 200 human cancer samples and normal DNA.

Their study was published in scientific journal Nature Communications.

The team’s Professor Matt Trau, said “inexpensive and portable detection devices’’ could eventually be tapped as diagnostic tools, “possibly with a mobile phone.

“We certainly don’t know yet whether it’s the Holy Grail for all cancer diagnostics.

“But, it looks really interesting as an incredibly simple universal marker of cancer, and as an accessible and inexpensive technology that doesn’t require complicated lab-based equipment like DNA sequencing,” he said.
