Between 1982 and 1987, 139 patients with primary carcinoma of the lung were treated with pneumonectomy. Thirty-nine patients (28%) were in clinical stage I, 10 (7%) were in clinical stage II, and 90 (65%) were in clinical stage III. Overall actuarial 3-year survival was 33%. Actuarial 3-year survival for patients in clinical stage I was 44%; for those in clinical stage II, 48%; and for those in clinical stage III, 28%. Risk factors for operative mortality examined included preoperative forced vital capacity (FVC) of 2.13 L or less and forced expiratory volume in 1 second (FEV1) of 1.65 L or less, percent predicted FVC of 64% or less and FEV1 of 65% or less, predicted postoperative FVC of 1.31 L or less and FEV1 of 0.89 L or less, and predicted postoperative percent predicted FVC of 41% or less and FEV1 of 34% or less. Operative deaths occurred only in clinical stage III patients (7/90 or 8%). Patients with compromised pulmonary function based on one or more of the examined risk factors were at increased risk for death (2/10) compared with patients with better pulmonary function (5/80 or 6.25%). Actuarial 3-year survival for high-risk clinical stage III patients ranged from 0% to 16% compared with 28% for other clinical stage III patients. Thirty-day mortality for pathological stage III patients was 6.3% (5/79), and 3-year actuarial survival was 24%. No patient in pathological stage III who was at high risk survived beyond 3.1 years. Select individuals with adequate pulmonary function and stage III disease can achieve substantial long-term survival after pneumonectomy.(ABSTRACT TRUNCATED AT 250 WORDS).
