BACKGROUND: The aim of this study was to compare the short and long-term results between sleeve resection (SR) and pneumonectomy (PN) in lung cancer patients over 70 years of age. METHODS: We retrospectively reviewed 105 lung cancer patients over 70 years of age who had undergone SR or PN at Shanghai Chest Hospital from January 2003 to December 2012. RESULTS: The SR group showed a higher frequency of airway clearance via bronchoscopy (48.6% vs. 25.7%, P = 0.04), longer surgical time (162.7 vs. 140.9 minutes, P = 0.01), and shorter postoperative stay (13.7 vs. 18.1 days, P = 0.02) than the PN group. There was no difference in hospital mortality (P = 1.00) or morbidity (P = 0.40) between the two groups. A logistic regression model showed that preoperative predicted forced expiratory volume in 1 second was the only independent risk factor for overall morbidity (P = 0.04). In survival analysis, SR showed better prognosis than PN (median 50.0 vs. 20.0 months, P < 0.01). In subgroup analysis, SR showed better survival in N0 (P = 0.03) and N1 (P < 0.01) cases, but not in N2 cases (P = 0.36). It also showed better survival in stage I + II patients (P = 0.03), but not in stage III patients (P = 0.10). CONCLUSIONS: Although PN could be carried out as safely as SR in patients over 70 years of age with a good pulmonary reservoir, SR is still recommended as a less traumatic procedure, sparing lung parenchyma with better long-term results.
