BACKGROUND: As the population ages, clinicians are increasingly confronted with octogenarians with resectable non-small cell lung cancer (NSCLC). We reviewed the outcomes of octogenarians who underwent lobectomy for NSCLC by video-assisted thoracic surgery (VATS) versus open thoracotomy, to determine if there was a benefit to the VATS approach in this group. METHODS: We conducted a retrospective single-institution review of patients age 80 years or greater who underwent a lobectomy for NSCLC from 1998 to 2009. Outcomes including complication rates, length of stay, disposition, and long-term survival were analyzed. RESULTS: One hundred twenty-one octogenarians underwent lobectomy: 40 VATS and 81 through open thoracotomy. Compared with thoracotomy, VATS patients had fewer complications (35.0% vs 63.0%, p = 0.004), shorter length of stay (5 vs 6 days, p = 0.001), and were less likely to require admission to the intensive care unit (2.5% vs 14.8%, p = 0.038) or rehabilitation after discharge (5% vs 22.5%, p = 0.015). In multivariate analysis, VATS was an independent predictor of reduced complications (odds ratio, 0.35; 95% confidence interval, 0.15 to 0.84; p = 0.019). Survival comparisons demonstrated no significant difference between the two techniques, either in univariate analysis of stage I patients (5-year VATS, 76.0%; thoracotomy, 65.3%; p = 0.111) or multivariate analysis of the entire cohort (adjusted hazard ratio, 0.59; 95% confidence interval, 0.27 to 1.28; p = 0.183). CONCLUSIONS: Octogenarians with NSCLC can undergo resection with low mortality and survival among stage I patients, which is comparable with the general lung cancer population. The VATS approach to resection reduces morbidity in this age demographic, resulting in shorter, less intensive hospitalization, and less frequent need for postoperative rehabilitation.
