title: Poor preoperative patient-reported quality of life is associated with complications following pulmonary lobectomy for lung cancer.
abstract: To assess whether quality of life (QOL) was associated with cardiopulmonary complications following pulmonary lobectomy for lung cancer.
  
  
  
  Retrospective analysis of 200 consecutive patients who had pulmonary lobectomy for lung cancer (September 2014-October 2015). QOL was assessed by the self-administration of the European Organisation for Research and Treatment of Cancer QLQ-C30 questionnaire within 2 weeks before the operation. The individual QOL scales were tested for a possible association with cardiopulmonary complications along with other objective baseline and surgical parameters by univariable and multivariable analyses.
  
  
  
  Forty-three patients (21.5%) developed postoperative cardiopulmonary complications; 4 of them died within 30 days (2%). Univariable analysis showed that, compared to patients without complications, those with complications reported a lower global health status (GHS) [59.1; standard deviation (SD) 27.2 vs 69.6; SD 20.6, P  =   0.02], were older (71.2; SD 8.4 vs 67.7; SD 9.4, P  =   0.03), had lower values of forced expiratory volume in one second (FEV1) (83.9; SD 27.2 vs 91.4; SD 20.9), P  =   0.06) and carbon monoxide lung diffusion capacity (DLCO) (67.9; SD 20.9 vs 74.2; SD 17.6, P  =   0.02) and higher performance score (0.76; SD 0.63 vs 0.53; SD 0.64, P  =   0.02). Stepwise logistic regression analysis showed that factors independently associated with cardiopulmonary complications were age [odds ratio (OR) 1.04, 95% CI 1.0-1.09, P  =   0.02] and patient-reported GHS [OR 0.98, 95% confidence interval (CI) 0.96-0.99, P  =   0.006], whereas other objective parameters (i.e. FEV1, DLCO) were not. The best cut-off value for GHS to discriminate patients with complications after surgery was 50 (c-index 0.65, 95% CI 0.58-0.72).
  
  
  
  A poor GHS perceived by the patient was associated with postoperative cardiopulmonary morbidity. Patient perceptions and values should be included in the risk stratification process to tailor cancer treatment.
