WASHINGTON (Reuters) – Elevated levels of three proteins show ovarian cancer is starting to grow years before women are diagnosed, but they do not increase soon enough to be an early indicator of the disease, U.S. researchers said on Wednesday.

The researchers analyzed blood samples from a large clinical trial and identified 34 women with ovarian cancer along with a control group of 70 women who did not have cancer. Their blood samples were used to evaluate six proteins identified as potential indicators of ovarian cancers.

The researchers say the synthetic platelets, made from polymers already approved by the U.S. Food and Drug Administration, bind with natural platelets that become activated at a wound and help blood clots form more rapidly, the researchers reported in Science Translational Medicine.
