Table 4 Multivariate analyses of risk and prognostic factors for short- and long-term results in elderly patients

From: A retrospective comparative analysis of elderly and younger patients undergoing pulmonary resection for stage I non-small cell lung cancer

  Predictive factors OR/HR (95 % CI) p
Short-term outcomes    
30-day mortality DLCO less than 70 % of prediction 17.1 (1.46–199) 0.024
90-day mortality DLCO less than 70 % of prediction 8.47 (1.11–64.6) 0.039
Complication rate Male gender 7.80 (3.10–19.6) <0.001
  DLCO less than 70 % of prediction 3.51 (1.03–12.0) 0.045
Hospital stay Open thoracotomy 6.75 (2.41–11.1) 0.003
  DLCO less than 70 % of prediction 8.64 (1.88–15.4) 0.013
Long-term outcomes    
5-year overall survival Squamous cell carcinoma 3.18 (1.56–6.48) 0.001
  DLCO less than 70 % of prediction 2.37 (1.10–5.14) 0.028
5-year disease-free survival Male gender 2.57 (1.29–5.09) 0.007
  DLCO less than 70 % of prediction 2.07 (1.07–4.00) 0.030
Recurrence rate within 2 years Stage IB 1.7 (1.04–2.75) 0.035
  1. DLCO: expected diffusing capacity for carbon monoxide
  2. OR: odd ratio from logistic regression model for short-term outcomes
  3. HR: hazard ratio from Cox proportional hazard model for long-term outcomes
  4. 95 % CI: 95 % confidential interval
