Outcomes of critically ill patients with lung cancer
16001 Background: Recent advances in oncology and critical care have resulted in improved survival in critically ill cancer patients. An appraisal of the prognosis of critically ill patients with lung cancer is timely. Methods: The aim of this study was to evaluate the outcomes and prognostic factors of critically ill cancer patients with lung cancer. From 2000 to 2005, patients with either small-cell (SCLC) or non-small-cell lung cancer (NSCLC) admitted at two intensive care units (ICU) in Brazil and France were included. Patients with postoperative care, ICU stay <24 h and readmissions were excluded. Demographics, clinical, cancer related and outcome variables were collected. Hospital mortality was the outcome variable of interest. Variables selected in the univariate analysis (p < 0.25) and those considered clinically relevant were entered in a multivariable logistic regression analysis [results were expressed as odds-ratios (OR), 95% confidence interval (CI)]. Results: A total of 132 patients were studied (INCA = 87, St Louis Hospital = 45). Their mean age was 61 ± 10 years and 73% were males. Twenty-five (19%) had SCLC and 107 (81%), NSCLC. The SAPS II score was 48 ± 21 points. The main reasons for ICU admission were severe sepsis (45%) and acute respiratory failure (33%). During ICU stay, 96 (73%) patients received mechanical ventilation, 76 (58%) vasopressors and 11 (8%) dialysis; 15 (11%) patients were treated with chemotherapy and 6 (5%), radiation therapy. Thirty-eight (29%) patients had end-of-life decisions. ICU and hospital mortality were 43% and 60%, respectively. Multivariable analysis identified three independent determinants of hospital mortality: airway obstruction/infiltration by cancer [OR = 2.87 (1.34–8.13), p < 0.001], number of organ failures [OR = 1.91 (1.01–2.74), p = 0.047] and performance status 3–4 before admission [OR = 2.90 (0.94–8.95), p = 0.065]. Conclusions: Improved survival in overall ICU cancer patients extends to patients with lung cancer, including those needing mechanical ventilation. Interestingly, the characteristics of the cancer are not associated with the outcome and should not be the grounds for the ICU decision making. Mortality is increased with the number of organ dysfunctions, in particular when respiratory failure is due to cancer progression. No significant financial relationships to disclose.
