    Background:
    Especially for elderly lung cancer patients, it would be important to evaluate the risks for postoperative complication and prognostic implication accurately. The aim of this study is to investigate whether Simplified Comorbidity Score (SCS) is useful for prediction of postoperative complication and prognosis.
    
    Methods:
    We reviewed 216 elderly lung cancer patients aged 75 years and older who underwent pulmonary resection by video-assisted thoracoscopic surgery (VATS) between January 2005 and December 2012. The SCS, which is one of the weighting and scoring system for patients’ comorbidities, summarized the following variables: tabacco consumption, diabetes mellitus and renal insufficiency (respective weightings = 7, 5 and 4), respiratory, neoplastic and cardiovascular comorbidities and alcoholism (weighting = 1 for each item). Patients were divided into high and low groups according to calculated SCS (cut-off valued = 9), and we analyzed the differences of perioperative factors and prognosis between these groups.
    
    Results:
    There were 154 patients with low SCS and 62 with high SCS. Limited resection was performed more frequently in high SCS group than in low SCS group (58% and 40%, respectively; p = 0.02). Postoperative complications were occurred more frequently in high SCS group than in low SCS group (15% and 45%, respectively; p < 0.01). High SCS was a significant predictive factor of postoperative complications by logistic regression analysis (Odds ratio: 2.7; p = 0.02). The five year overall survival was 74% for low SCS group and 49% for high SCS group, respectively, with a significant difference (p < 0.01).
    
    Conclusion:
    SCS could provide useful information about postoperative complications and prognosis in elderly lung cancer patients with VATS treatment.
