▼ A new blood test shows promise for detecting many types of cancer, even in the early stages of the disease, according to a new study.
In the study, researchers found that the test could detect 10 types of cancer and that it was 80 to 90 percent accurate for some cancer types.
However, much more research is needed before doctors will be able to use the test on their patients, experts say.
"This is a very promising study," said Dr. Kazuaki Takabe, the Alfiero Foundation endowed chair in breast oncology at the Roswell Park Comprehensive Cancer Center in Buffalo, New York, who was not involved with the study. However, Takabe stressed that the work is very preliminary. "Clearly, this is just the beginning," Takabe said. "We need more and more and more samples" to determine the true accuracy of the test.
In addition, the study included patients who had already been diagnosed with cancer, so more studies are needed to investigate whether the test can detect cancer in its earliest stages, before people are typically diagnosed with the disease.
The study, led by researchers at the Cleveland Clinic Taussig Cancer Institute, will be presented June 4 at the annual meeting of the American Society of Clinical Oncology in Chicago.
Blood test for cancer
The test, referred to as a " liquid biopsy," looks for small pieces of DNAthat are released from cancer cells into the blood. (▪ ▪ ▪)
