Abstract

This investigation evaluated whether the performance at a preoperative symptom-limited stair-climbing test was a prognostic factor in resected pathologic stage I non-small cell lung cancer (NSCLC).Observational analysis was performed on a prospective database that included 296 patients who underwent pulmonary lobectomy for pathologic stage T1 N0 or T2 N0 NSCLC (2000 to 2008). Patients who received induction chemotherapy were excluded. Survival was calculated by the Kaplan-Meyer method. The log-rank test was used to assess differences in survival between groups. The relationships between survival and baseline and clinical variables were determined by Cox multivariate analyses.Median follow-up was 43 months. The best cutoff associated with prognosis was an 18-meter stair climb. Median (months) survival and 5-year survival of patients who climbed more than 18 meters were significantly longer than those who climbed less than 18 meters (97 vs 74; 77\% vs 54\%, p=0.001). Cox regression model (hazard ratio) showed that climbing more than 18 meters (0.5; p=0.003), diffusion capacity of the lung for carbon monoxide (0.98; p=0.02), and pT stage (1.8; p=0.02) were independent prognostic factors. Patients who climbed less than 18 meters had increased deaths from cancer (24\% vs 15\%, p=0.1) or other causes (19\% vs 9\%, p=0.02).Preoperative cardiopulmonary fitness is a significant prognostic factor in patients after resection for early-stage NSCLC. Interventions aimed at improving exercise tolerance can be useful to improve long-term prognosis after NSCLC operations.
