We assessed the capacity to predict surgical mortality, complications, and functional loss by using the results of resting and exercise respiratory function. Measurements were made before and 4 mo after lung resection in 54 consecutive patients with bronchogenic carcinoma. Predicted postoperative (ppo) FEV1 and DLCO were derived using quantitative lung perfusion scans when baseline FEV1 was 55% predicted. The patients were aged 67 +/- 7 (mean +/- SD) yr, with an FEV1 of 76 +/- 23% predicted, FEV1/FVC of 55 +/- 13%. and DLCO of 85 +/- 22% predicted. Eleven of the patients had pneumonectomy, 29 had lobectomy, 12 had wedge resection, and two had no resection. Wilcoxon and stepwise logistic reg..View full abstract
