Risks and rewards of the surgical treatment of lung cancer in octogenarians

OBJECTIVES: Surgeons will face an increasing number of octogenarians with lung cancer potentially curable by surgery. The goal of this study was to evaluate short- and long-term outcomes after lung resection. METHODS: We performed a single-centre study of consecutive patients >= 80 years old, surgically treated for suspected lung cancer between 2009 and 2016. Age, sex, performance status, lung function, surgical approach, type of lung resection, complications, in-hospital and 30- and 90-day deaths and long-term survival were analysed. RESULTS: Two hundred and fifty-seven patients were enrolled. The median age was 82 years (range 80-97). One hundred and thirty-four patients were treated by thoracotomy and 123 by video-assisted thoracic surgery [10 (8.1%) converted]. Two hundred and thirty-two underwent lobar resection and 25 underwent sublobar resection. There were no intraoperative deaths and 9 admissions to the intensive therapy unit; 112 (43.6%) patients suffered complications: More complications occurred after lobar versus after sublobar resections [45.7% vs 24% (P = 0.037)] and in those with chronic obstructive pulmonary disease (COPD) [57.4% vs 40% (P = 0.02)]. The 30-day mortality was 3.9% (n = 10) and the 90-day mortality was 6.22% (n = 16). One hundred and sixty-seven patients died during the study period; patients with non-small-cell lung cancer (n = 233) had a median survival of 46.5 months with 67.2% alive at 2 years and 40.8% at 5 years. Pathological stage and R status were independent prognostic factors for survival. CONCLUSIONS: Surgery for malignancies in octogenarians is feasible and safe with good long-term outcomes. The risk of postoperative complications, especially in those with COPD, is high but can be minimized with sublobar resection. Postoperative mortality is acceptable, and long-term survival is primarily governed by lung cancer stage. Age is no reason to deny patients surgery for early-stage disease.
