New Test Detects Ovarian, 7 Other Cancers Using Simple Blood Sample
Ovarian cancer detection may become easier and without an expensive bill attached as researchers developed the first test that screens for this and seven other common cancer types using a simple blood sample. The test, called CancerSEEK, measures the levels of proteins specific for eight common cancers in the U.S., five of which have no current standard screening test, and detects mutations in cancer genes from DNA circulating in the blood. "The use of a combination of selected biomarkers for early detection has the potential to change the way we screen for cancer, and it is based on the same rationale for using combinations of drugs to treat cancers," study lead author Nickolas Papadopoulos, PhD, professor of oncology and pathology at Johns Hopkins University School of Medicine, said in a press release. The study, "Detection and localization of surgically resectable cancers with a multi-analyte blood test," was published in the journal Science. The researchers at Johns Hopkins Kimmel Cancer Center began testing several genes and proteins and came down to segments of 16 genes and eight proteins to test further. They tested it in 812 healthy controls and found only seven false positives – when a condition is detected as present when in
