Simple blood test can detect early cancer

The detection of many types of cancer may soon be as easy as a simple blood test, according to a new study. The blood test was developed by researchers at Stanford University School of Medicine, which also can be used to "keep an eye on the amount of cancer in the patient's body," said the researchers, in addition to measuring their response to a variety of treatments.

The test, called CAPP-Seq or Cancer Personalized Profiling by deep Sequencing, is a refinement of the approaches already exist to measure the levels of tumor DNA in the blood stream of patients, according to the study.

The new method is able to "accurately identify approximately 50 percent of the people who studied with lung cancer stage-1 and all patients with more advanced cancer," according to the researchers.

Other parties who are not involved in this study hopes. "I think this is important progress in this area," said Dr. Abhijit Patel of the Yale Cancer Center and Smilow Cancer Hospital, where he was doing similar research. "The goal is to detect very small tumors in early stage."

Patel said one of the major breakthroughs in this test is the ability to keep an eye on changes in DNA mutations in patients with cancer who are already receiving treatment and may develop resistance to a particular drug.

He also said the test was most likely will not give false positive results due to "cancer DNA mutations most likely not be found in healthy people." And the results of this study published in the April 6, 2014 issue of Nature Medicine. *** [EKA | FROM VARIOUS SOURCES | VOA NEWS]
