ABSTRACT
Surgery is the treatment of choice for patients with stage I or II non-small cell
carcinoma of the lung. Many such patients will have concurrent chronic obstructive
pulmonary disease, the presence of which may increase the risk of lung resection.
Prediction of surgical morbidity and mortality related to impaired pulmonary physiology
should be based on evaluation of physiological parameters. Such measurements can be
derived from a variety of studies including pulmonary function testing, assessment
of split lung function, and measurements of exercise capacity. While there does not
exist uniform agreement about threshold levels of risk related to individual tests,
judicious use of widely available physiological measurements including FEV1, DLCO, and VO2max should enable clinicians to make reasonable assessments of operative risk. Because
surgery is clearly optimal treatment for stages I and II non-small cell lung cancer,
thoughtful consideration should be given to the decision of operability in each individual
case.
