Significance of measuring the severity of emphysema, in combination with spirometry, on the risk evaluation of patients undergoing major lung resection for cancer†.

ABSTRACT:

Objectives

Predicted postoperative forced expiratory volume in 1 s (ppoFEV1) and predicted postoperative diffusing capacity of the lungs for carbon monoxide (ppoDLco) are the two most significant parameters for predicting the risk of cardiopulmonary complications after major lung resection for lung cancer. Although the severity of pulmonary emphysema on computed tomography may be an important risk factor for postoperative complications, the clinical significance of measuring the severity of pulmonary emphysema, in combination with ppoFEV1 and ppoDLco, has never been evaluated.

Methods

We measured the severity of pulmonary emphysema, representing the percentage of low-attenuation area (< -950 Hounsfield units), in the whole lung field, in addition to ppoFEV1 and ppoDLco, in 4
