Pre-Op II

You are evaluating a 50 year old smoker for lung resection for localized non-small cell lung cancer. Pre-operative pulmonary function tests include: FEV1 1.8 L, 75% of predicted, preoperative DLCO 90%, predicted post-operative FEV1 is 900mL or 45% of predicted.

Challenge: What is your interpretation of this data?

Pre-Op II

For patients undergoing pneumonectomy, if the pre-operative FEV1 is >2L or >80% and DLCO is >80%, then it is acceptable to proceed with surgery. Since this patient’s FEV1 is <2L and <80%, post-operative values are calculated based on quantitative perfusion, ventilation, or CT scan. A post-operative FEV1 >800cc or >40% predicted is acceptable.
