Eight Cancers Could Be Diagnosed With A Blood Test

This is great news, when it comes to Cancer diagnosis it can be a long and challenging process. But, a new method may offer a simpler, more effective way of of diagnosing the disease.

According to Medical News today:

In the new study, researchers reveal how the blood test demonstrated high sensitivity and specificity for cancer detection in more than 1,000 people with the disease.

When cancerous tumors form, they release small fragments of mutated DNA and proteins into the bloodstream, and these can act as markers for cancer.

The new blood test works by identifying the markers for 16 gene mutations and eight proteins that are associated with eight different cancer types. These include breast, lung, and colorectal cancer, as well as five cancers — ovarian, liver, stomach, pancreatic, and esophageal — for which there are currently no routine screening tests for people at average risk.

They found that the test was able to identify 70 percent of the cancers, with sensitivity ranging from 33 percent for breast cancer to 98 percent for ovarian cancer. Sensitivity ranged from 69 percent to 98 percent for the five cancers that currently have no routine screening tests, the researchers report.

In terms of specificity, the test yielded an overall result of more than 99 percent. On testing CancerSEEK on 812 healthy adults, it only produced seven false-positive results.

However, the team believes that the results of its current research are encouraging.

“This has the potential to substantially impact patients. Earlier detection provides many ways to improve outcomes for patients,” says study co-author Dr. Anne Marie Lennon, Ph.D., who is an associate professor of medicine, surgery, and radiology at Johns Hopkins.

“This test represents the next step in changing the focus of cancer research from late stage disease to early disease, which I believe will be critical to reducing cancer deaths in the long-term.”
