Lung Cancer Diagnosis may be Simplified by New Blood Test
This false-positive rate has important clinical implications in cost and side effects. A recent report in the Annals of Internal Medicine showed that CT scans, often used as a follow-up to X-rays, were linked to cancer because of their high doses of radiation.
Steven Dubinett, M.D., professor of medicine and pathology, and director of the Lung Cancer Research Program at the Jonsson Comprehensive Cancer Center at the David Geffen School of Medicine, University of California, Los Angeles, said that while findings regarding the detrimental effects of imaging studies like CT scanning are still somewhat controversial, the need for more accurate testing is not.
In a study presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer, Dubinett and colleagues assembled a 40-marker panel of potential lung cancer biomarkers based on previous investigations from 90 patients with lung cancer as well as 56 control patients thought to be at high risk due to their smoking histories.
"The diagnosis of an indeterminate pulmonary lesion can be difficult, and current methods for confirming an abnormal imaging study include invasive procedures for biopsies," said Dubinett. "We anticipate that in the future, blood tests will be clinically relevant and lead to reduced use of more invasive diagnostic measures."
