‘App’ helps predict if lung lesions seen on CT are cancerous or benign: study

Canadian researchers have developed a software app that they hope will improve lung cancer screening around the world. The risk-calculating software can predict with a high level of accuracy whether lesions, or nodules, in the lungs detected on a CT scan are likely to be malignant or benign.That can help doctors determine whether a patient at high risk for lung cancer is likely to need an invasive biopsy or surgery, said co-principal investigator Dr. Stephen Lam, chair of the Provincial Lung Tumour Group at the B.C. Cancer Agency. The software was developed by Martin Tammemagi, an epidemiologist at Brock University in St. Catharines, Ont., and a member of the cross-Canada research team whose findings from two studies are reported in this week’s issue of the New England Journal of Medicine.
