Liquid biopsy- Detects 8 types of Cancer

A single blood test can be used to detect different types of cancer on one day, as a result of preliminary trail .

In past, experimental test called liquid biopesis, that could detect and track tumor from simple blood draw. Some of these test are designed to detect single kind of cancer by spotting tumor associated mutations in DNA sequences found in the blood that floats freely.

This latest study, is incredible that it tests only for these DNA mutations, but for certain levels of certain proteins , in an effort to detect eight different cancers. The test could detect disease in about 70% more than 1000 people who have been diagnosed with cancer already.

These researchers belief that their work could lead to test which is simpler and cheaper than intensive sequencing involved in some other liquid biopesis. They came to a conclusion that , it would be more cost effective approach said by Nitzan Rosenfeld.

Needle in a haystack

Academic and industry people have focused  on using liquid biopesis  to detect cancer evolution and that could guide physicians for treatment plan.

But oncologist Nickolas Papadopoulos and his team want to develop a test that could detect cancer at earliest, So that it is easy to treat.

These tests are challenging: small  tumors don’t  release  much DNA into blood stream usually compared to larger tumors. An incorrect result can cause people stress  and harmful to treatments.

The researchers are looking to make liquid biopsy more sensitive without the risk of false positive result. They  tested this technique who have already diagnosed with 1 of 8  cancers: liver, stomach, pancreatic, esophegal, colorectal,  lung. They removed individual  in whom the cancer is spread already.
