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

Abstract

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. 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. 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. 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.
