Cancer bronchique : le pronostic en soins intensifs dépendrait surtout de la complication

Introduction It has been demonstrated in unselected populations of cancer patients that prognosis in intensive care is essentially dependent on the extent of the acute physiological disturbance caused by the complication precipitating the admission. By contrast, the prognosis after hospital discharge remains dependent on the characteristics of the underlying neoplasm. The aim of our study was to confirm whether this general finding was the case in a specific population of lung cancer patients, since there are no data on this patient group in the literature. Patients and methods We conducted a retrospective study including all patients with lung cancer admitted to our ICU between September 1, 2008 and December 31, 2013. Results During this period, 180 different patients with lung cancer were admitted into ICU. The simplified acute physiology score II (SAPS II) (OR 1.07 ; 95% CI 1.04-1.11), respiratory failure (OR 4.00; 95% CI 1.76-9.07) and the presence of therapeutic limitations were the 3 factors independently affecting hospital mortality in multivariate analysis. Considering only patients discharged alive from the hospital, the presence of metastases (HR 2.30; 95% CI 1.44-3.65) and limitations on therapy (HR 5,89; IC 95% 3,11-11,14) were the two statistically independent prognostic factors for overall survival. Conclusion In this population of lung cancer patients admitted into ICU, independent predictors of hospital mortality are determined by the physiological perturbations induced by the acute presenting complication. After recovery from this, prognosis is again determined by the characteristics of the underlying cancer.
