Survival and function after sleeve lobectomy for lung cancer

Between 1962 and 1991, 72 patients (mean age 63.4 years) underwent sleeve lobectomy for primary lung cancer, Thirty-seven patients had adequate lung function and 35 were deemed unsuitable for pneumonectomy on the basis of inadequate pulmonary reserve (n = 31) or cardiac risk factors (n = 4), Squamous cell carcinomas (68%) and adenocarcinomas (26%) predominated. Upper lobectomy was performed in 48 patients, lower and middle lobectomy in 13, and right upper and middle bilobectomy in 11, Hospital mortality was 4% (3/72) and compares with a hospital mortality of 9% in 56 consecutive pneumonectomies between 1986 and 1990, Major complications occurred in 11% (bronchopleural fistula 1, persistent atelectasis 4, pneumonia 4), Adjusted actuarial survival after sleeve lobectomy at 1 and 5 years was 84% and 42%, compared with 76% and 44% after pneumonectomy, Five-year survival after lower and middle lobectomy in 13 patients (52%) was similar to that after upper lobectomy (46%), suggesting that in carefully selected patients the concept of sleeve lobectomy can be applied to all pulmonary lobes, N1 disease and compromised lung function were associated with lower survival (N1 38% vs N0 57%; compromised 20% vs adequate 55%), Comparison of preoperative and postoperative lung function and quantitative ventilation-perfusion isotope studies substantiated the preservation of pulmonary function in this group of patients. Sleeve lobectomy is the procedure of choice for anatomically suitable carcinomas or when reduced pulmonary reserve precludes extensive resection.
