Malignancy risk probabilities were significantly higher (Brock p\u2009&lt;\u20090.00001; Mayo p\u2009&lt;\u20090.00001) in those undergoing diagnostic sampling than those not undergoing sampling. However, there was no difference in the Brock ( p\u2009=\u20090.912) or Mayo ( p\u2009=\u20090.435) calculators when discriminating a final diagnosis of cancer from not cancer in those undergoing sampling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In our screening program, 5.7% of individuals undergo invasive testing, comparable with the National Lung Screening Trial (6.1%). Both Brock and Mayo calculators perform well in indicating who may be at risk of malignancy, based on clinical and radiologic factors. However, in our invasive testing group, the Brock and Mayo calculators and Lung Cancer Screening Program clinical assessment all lacked clarity in distinguishing individuals who have a cancer from those with a benign abnormality.<\/jats:p>\n
