Shorter follow-up for lung lesions equals better outcomes - AuntMinnie

The results could change the way clinicians care for patients with lung findings classified as Lung-RADS 3 (probably benign), wrote a group led by Mehrad Bastani, PhD, of Stanford University.

"Our [study supports] the notion that both individuals and physicians [should be] highly encouraged to ensure the diagnostic follow-up examinations for subjects with Lung-RADS category 3 nodules are implemented earlier or no later than the current recommended six-month interval," the team wrote.

The American College of Radiology's Lung CT Screening Reporting and Data System (Lung-RADS) was developed to standardize diagnostic follow-up of suspicious findings on CT lung cancer screening. But the timing of this follow-up, particularly for category 3 (probably benign) and 4A (suspicious), remains open to debate.

"The National Lung Screening Trial (NLST) demonstrated that screening with low-dose CT (LDCT) reduces [lung cancer]-specific mortality by 20% compared with chest radiography among high-risk patients," the group wrote. "However, the NLST had no standard follow-up protocol for suspicious pulmonary nodules of unknown clinical significance (aka, indeterminate findings)."

Bastani and colleagues evaluated the effectiveness of various follow-up intervals for Lung-RADS 3 and 4A lesions. They used the Lung Cancer Outcome Simulator (LCOS) -- a tool developed by the Cancer Intervention and Surveillance Modeling Network Consortium -- to estimate outcomes among a simulated 1960 population level cohort of 1 million men and women for different follow-up periods, based on the U.S. Preventive Services Task Force (USPSTF) lung cancer screening guidelines.

The current recommended follow-up interval for Lung-RADS 4A lesions is three months, and the modeling study confirmed that this timeframe is best. But for lesions categorized as Lung-RADS 3, the group determined that five months rather than the recommended six-month follow-up translated into better outcomes in a simulated cohort of 1 million people.

Impact of reducing follow-up from 6 to 5 months for indeterminate lung lesions on CT
  6-month follow-up 5-month follow-up Difference
Mortality reduction 6.89% 6.97% 0.08 percentage points
Deaths averted 3,253 3,217 36 deaths
Screen-detected cases of cancer 14,561 14,582 21 cases
No. of LDCT scans and diagnostic follow-ups per death averted 738 730 8
Life-years gained 44,068 life years 44,667 life-years 599 life-years

The study shows that patients with indeterminate lesions on low-dose CT lung cancer screening should be urged to follow through on follow-up, according to the researchers.

"Patients with Lung-RADS 3 nodule findings are encouraged to avoid any follow-up delays despite their low malignancy risks," they concluded.
