An innovative "biochip" filter washes the blood of cancer sufferers

A new technique washes the blood of cancer patients and reduces the cost of treatment.

An innovative

Researchers at the University of New South Wales have developed a new system that could dramatically reduce the cost of cancer treatment by washing the blood clean of cancer cells. 

This new system takes the form of a “biochip”, which filters the blood of cancer sufferers to identify and remove cancer cells from the bloodstream in what is being termed as “dialysis for cancer”.

The system was initially designed as a less expensive and less painful way to diagnose cancer. Currently, identifying a tumour involves expensive scans and painful biopsies.

About 99 per cent of human cancers are solid, but these masses can shed circulating tumour cells into the bloodstream, which is how cancer can spread throughout the body.

Dr Majid Warkiani and the team at NSW University created the biochip in order to separate these cancerous cells from healthy cells.

"We are simply getting the blood from the patient, it's a mixture of normal blood cells and cancer cells," said Dr Warkiani. "We put it inside one of our biochips and the cells go under migration, and they get affected by hydrodynamic forces.

"Under those forces that we are applying to the cells inside the chip, the bigger cells go up to the cancer cell outlet, and the smaller cells get pushed down and essentially they get fractionated, they get separated."

It is hoped that the chip will not only be used to diagnose the cancer, but also to significantly reduce the cost of treatment. 

Currently the cost of a tumour scan is around $700 per scan. But with the use of the biochip, these costs could be reduced to between $50–$100.

But scientists are now looking for other ways in which the biochip could be useful for more than just diagnosis.  It is believed that the chip could be upsized to wash a patient's own blood of cancer cells, then returned to the body, similar to the process for kidney dialysis. This, in turn, could extend the lives of people suffering from cancer, as well as having the potential to save those who have gotten over the insidious disease from relapsing.

According to Dr Warkiani, all that is needed is proper funding and support, for the biochip technology to be in service around Australian hospitals within two or three years.

So far the team has applied for government funding and been knocked back six times in less than two years. Although Dr Warkiani is hopeful that recently flagged funds intended for innovation will give them the money they need to get this project off the ground.

"We should find a new way, and I believe that this is a new way to do cancer management," he said.


What do you think of this innovative system to diagnose and treat cancer?

    Doesn't seem like a particularly exciting advance - because if a cancer tumour has started and it's growing, it will continue to grow, regardless of how much blood "washing" is done.
    Obviously, the area of interest to the medical fraternity is that this washing process will help prevent the spread of tumours to other organs - as is common in many cancer sufferers.
    However, the bottom line is that many people have inherited damaged DNA cells, which makes them very prone to catching various forms of invasive cancers - and I see little hope of a cure for cancer, until researchers can find the way to stop cancers initially getting a foothold in those mutated cells.
    However, I guess any advance, no matter how small, has to be another part of the huge cancer jigsaw put into place.

    Good opinion Aaron. "washing the blood clean of cancer cells" is a remedy not a cure.
    "Researchers at the University of New South Wales have developed a new system that could dramatically reduce the cost of cancer treatment " I wonder about the cost.

    There was such a blood cleansing machine some years ago it also cleansed not just cancer but rheumatoid. Was here one minute then gone the next. I guess it came up against the might of BIGpharma who bought it out and lost it.

    I am praying for PM + Ms. Ley to hasten our plea for legalised medicinal cannabis on medical card as many auto immune diseases, inflammation & cancers have had remission whilst on it overseas.

    Some medications I believe also causation of cancers. I am on Prednisolone and it's notorious for BBCancers. Some of the cancer drugs also responsible for cancer/s.

    Sounds like a cheaper way of deciding if further more expensive and invasive diagnostic tests are necessary.

    I have read about a bio-laser light reflector apparatus which if placed directly in front of a politician would make her or his artificial grin shatter. However, unfortunately the gizmo to replace the grin with a genuine, sincere smile has yet to be invented. And probably never will.

    This "gizmo", as you call it, is not something which is inVENTED. It is inSTILLED and inGRAINED and it is called "honesty" - a trait which is devoid in most politicians.
