Implication

Study investigates smoking's effect on lung function predictions post-surgery in lung cancer patients, highlighting significant differences based on smoking status.

Key Points

This research aims to determine how smoking status affects the accuracy of predicting postoperative lung function indices in lung cancer patients using VRI.
Analyzed 37 patients with non-small cell lung cancer before and after anatomical lung resection.
Performed comprehensive spirometry and diffusion measurements pre- and post-surgery.
Used proprietary software (O-Plan) for calculating predicted postoperative values.
In smokers, predicted values of FEV1 and D L,CO were underestimated compared to actual measurements.
Mean difference for smokers: FEV1 was lower by 7.5% and D L,CO by 6.9%.
Non-smokers showed no significant difference between predicted and actual values.
