Investigation reveals that coexisting COPD influences predicted postoperative lung function values in patients undergoing resection.

Key Points

This research aims to determine if coexisting COPD affects the accuracy of predicted postoperative lung function values calculated with VRI in lung cancer patients.
Studied 17 patients with non-small cell lung cancer referred for anatomical resection.
Conducted comprehensive spirometry and diffusion measurements before and after surgery.
Utilized vibration response imaging (VRIxp) to calculate predicted postoperative values (ppo) using proprietary software O-Plan.
Strong correlations were found between predicted and measured ppoFEV1 and ppoDL,CO values postoperatively.
In the COPD group, the prediction accuracy for ppoFEV1 was higher compared to the non-COPD group.
No significant difference in ppoDL,CO prediction accuracy between COPD and non-COPD groups.
