ROCHESTER Minn. – A team of researchers including investigators from Mayo Clinic has identified a technology to address the problem of false positives in CT-based lung cancer screening. The team’s findings are published in the current issue of PLOS One.
“As physicians, one of the most challenging problems in screening patients for lung cancer is that the vast majority of the detected pulmonary nodules are not cancer,” says Tobias Peikert, M.D., a pulmonologist at Mayo Clinic. “Even in individuals who are at high risk for lung cancer, up to 96 percent of nodules are not cancer.”
Dr. Peikert says false-positive test results cause significant patient anxiety and often lead to unnecessary additional testing, including surgery. “False-positive lung cancer screening results also increase health care costs and may lead to unintentional physician-caused injury and mortality,” Dr. Peikert says.
To address the problem of false positives in lung cancer screening Dr. Peikert and Fabien Maldonado, M.D., from Vanderbilt University, along with their collaborators used a radiomics approach to analyze the CT images of all lung cancers diagnosed as part of the National Lung Cancer Screening Trial. Radiomics is a field of medicine that involves extracting large amounts of quantitative data from
