TOPLINE:
After lung cancer screening (LCS), imaging and invasive procedures were performed 31.9% and 2.8% of the time, respectively. Complications during invasive procedures occurred in 30.6% of cases.
METHODOLOGY:
- Researchers analyzed data from 9266 patients aged 55-80 years who completed at least one LCS with low-dose CT (LDCT) between 2014 and 2018.
- This study used data from the PROSPR Lung Consortium.
- Results were compared with findings from the National Lung Screening Trial (NLST), a large study of smokers published in 2011.
TAKEAWAY:
- In total, 2956 patients (31.9%) underwent follow-up imaging, including CT, LDCT, MRI, or PET; 180 (0.02%) had invasive procedures, including needle biopsy, bronchoscopy, mediastinoscopy or mediastinotomy, or thoracoscopy.
- Within 30 days after an invasive diagnostic procedure, 55 of 180 patients (30.6%) experienced complications; 20.6% were major, 8.3% were intermediate, and 1.7% were minor.
- Complication rates after invasive procedures were higher in PROSPR than the NLST (30.6% vs 17.7%).
- Compared with all patients, those with an abnormal LCS were slightly older, more likely to currently smoke, reported more packs of cigarettes smoked daily, and had more comorbid conditions.
- In 2013, the US Preventive Services Task Force recommended annual LCS for certain people who smoke, on the basis of findings from the NLST.
IN PRACTICE:
"We observed higher rates of both invasive procedures and complications than those observed in NLST, highlighting the need for practice-based strategies to assess variations in the quality of care and to prioritize LCS among those patients most likely to receive a net benefit from screening in relation to potential complications and other harms," the researchers wrote.

LIMITATIONS:
This study was retrospective, and data were analyzed using procedural coding. In addition, the NLST based abnormal findings on different criteria from those used in clinical practice (Lung-RADS), making direct comparison of patients difficult. Patients in PROSPR were older, more likely to be currently smoking, and had higher rates of comorbid conditions compared with patients in the NLST.
