A
new cancer blood test worked better for some types than others, and caught only 43 % of stage 1 cancers.
Their new test, which examines cancer - related DNA and proteins in the blood, yielded a positive result about 70 % of the time across eight common cancer types in more than 1000 patients whose tumors had not yet spread — among the best performances yet for a
universal cancer blood test.
The quest
for cancer blood tests — known as liquid biopsies — is one of the hottest areas in oncology, notes Otis Brawley, chief medical and scientific officer at the American Cancer Society, but there's a long way to go: «The tests reported so far have really terrible specificity.»
This cancer blood test is promoted by CEO Jay Flatley as the «turning point» in the war on cancer.
Researchers at New York City's Weill Cornell Medical College and Cornell University College of Engineering in Ithaca are also developing
a cancer blood test, although theirs uses a «geometrically enhanced differential immunocapture» (GEDI) silicon chip that can identify and collect cancer cells from a patient's blood sample.
Its early days for me yet am just coming up to 1 year past chemo but my last 2
cancer blood tests were down which is where I want them to be, heres hoping for more down results as then I will know this is working for me.
