We sought to determine the short- and long-term prognoses among ‘marginal-risk’ non-small cell lung cancer patients who have a predicted postoperative- (ppo) forced expiratory volume in the first second (FEV1) of 30–60% and/or a ppo-diffusing capacity of the lung for carbon monoxide (DLCO) of 30–60%. The present study included 73 ‘marginal-risk’ and 318 ‘normal-risk’ patients who underwent anatomical resection for clinical stage I lung cancer between 2008 and 2012. The rates of postoperative morbidity, prolonged hospital stay, and overall survival were assessed. Postoperative morbidity occurred in 35 (48%) ‘marginal-risk’ patients and 66 (21%) ‘normal-risk’ patients, and 17 (23%) ‘marginal-risk’ patients and 20 (6%) ‘normal-risk’ patients required a prolonged hospital stay. The three- and five-year survival rates were 79% and 64% in the ‘marginal-risk’ patients and 93% and 87% in the ‘normal-risk’ patients, respectively. A ‘marginal-risk’ status was a significant factor in the prediction of postoperative morbidity (odds ratio [OR] 2.97, p < 0.001), the rate of prolonged hospital stay (OR 3.83, p < 0.001), and overall survival (hazard ratio 2.07, p = 0.028). In conclusion, ‘Marginal-risk’ patients, who are assessed based on ppo-values, comprise a subgroup of patients with poorer short- and long-term postoperative outcomes.
