      Background

      Several protocols are available to guide management of lung nodules identified by low-dose screening CT. It is important to objectively assess their clinical utility in order to weigh the potential harm versus potential beneficial impacts of the following: early recall imaging studies/biopsy and health care resource utilization. We aimed to prospectively evaluate clinical utility of the PanCan lung nodule management protocol in the International Lung Screen Trial (ILST).

      Method

      Ever smokers age 55 to 80 years were enrolled into ILST if they has a ≥30 pack-years smoking history and smoked within 15 years or if their PLCO m2012 6 year lung cancer risk was ≥1.51%. Figure 1 shows the ILST lung nodule management protocol based on the PanCan nodule malignancy risk calculator (NEJM 2013;369:908 & BMJ 2014;348:g2253).

      Result

      Since July 2016, 757 ever smokers (mean age 65 years, 44% female, 15% non-Caucasian) had been enrolled. The distribution of malignancy risk categories (CAT) were: CAT1 70%, CAT2 15%, CAT3 11%, CAT4 3.5%, CAT5 0.4%. CT biopsy or bronchoscopic biopsy for diagnosis/staging was done in 16/26 CAT 4 (62%) and 7/84 CAT 3 (8%) participants. Lung cancer was confirmed in 15/757 (2%). Thus far, surgery was performed in 9 CAT 4 and 2 CAT 3 participants, with one benign resection (9%) for a growing FDG avid nodule. Of the 3 CAT5 participants, one was found to have granulomatous changes in an enlarged paratracheal lymph node and two had segmental atelectasis due to mucoid impaction.

      Conclusion

      The ILST protocol triaged 70% of the screening cohort with low malignancy risk to biennial screening instead of annual repeat screening. Participants with high malignancy risk (CAT 4+5) were triaged to a diagnostic pathway (4%). Our preliminary results suggest the ILST protocol may decrease resource utilization and potentially minimize risk of screening for participants.
