WCM Featured for Liquid Biopsies that are Transforming Cancer Care

Fox 5's "Big Idea" segment recently profiled Weill Cornell Medicine for its use of liquid biopsies, a relatively noninvasive diagnostic test that can help doctors learn more about a patient's tumor so they can fight it more effectively.

In the past, doctors could only gather tumor cells by physically extracting a sample of tissue or through surgery. But with a liquid biopsy, a simple blood test gives physicians access to those cells.

Liquid biopsies take advantage of cells that break off the tumor and travel through the blood, explained Dr. Scott Tagawa, a Weill Cornell Medicine oncologist and researcher.

"As those cells travel around in the blood we can capture them in a test tube. We could then take those individual cells from the test tube and analyze them," Dr. Tagawa told Fox 5.

Fox 5 also profiled Alex Sarmiento, a Weill Cornell Medicine patient diagnosed with prostate cancer, and showed how the test dramatically improved the 77-year-old's health. At first, treatment kept his health stable, but after a trip to the Philippines, his condition took a turn for the worse. Doctors drew blood to collect a liquid biopsy, which allowed them to analyze Sarmiento's tumor cells and spot a mutation quickly.

"The liquid biopsy helped me quickly make a treatment decision [and] get him a drug that was very effective without a whole lot of toxicity," said Sarmiento's physician, Dr. David Nanus, who is also the chief of hematology and oncology at Weill Cornell Medicine.
