Prognostic factors for patients with lymphoma requiring intensive care

17519 Background: Prognosis of patients (pts) with hematological malignancies (HM) in the intensive care unit (ICU) seems to be improving, despite different biological behaviors and outcomes. The study of homogenous groups of pts might provide useful clinical insights. The aim of this study was to evaluate the outcomes of critically ill patients with lymphomas (CIPL). Methods: During 66 months, all consecutive CIPL admitted to an oncologic ICU were studied. Variables collected were: age, gender, performance status, type and status of lymphoma, neutropenia, infection at admission, use of mechanical ventilation (MV), the Acute Physiology and Chronic Health Evaluation (APACHE) II score, comorbidities and number of acute organ failures (AOF). Variables selected in the univariate analysis (p < 0.25) and those clinically relevant were entered in a multivariable logistic regression analysis [results expressed as odds-ratios (OR), 95% confidence interval (CI)]. The end-point was hospital mortality. Results: A total of 120 CIPL were studied. Mean age was 51 ± 20 years and 54% were males. APACHE II was 19 ± 7 points. Diagnoses were High Grade Non-Hodgkin’s Lymphoma (77.5%), Hodgkin’s disease (17.5%) and Low Grade Non-Hodgkin’s Lymphoma (5%). Reasons for ICU admission were severe sepsis (62%) and acute respiratory failure (22%). During ICU stay 90% pts received MV, 71% vasopressors and 27.5% dialysis. Twenty-three (19%) pts had neutropenia. End-of-life decisions were implemented in 31% pts and all of them died at the ICU. The ICU and hospital mortality rates were 53% and 67% respectively, with no difference among the groups of lymphomas (p = 0.877). Variables identified in the multivariate analysis were: age [OR = 1.03 (95% CI = 1.01–1.06)], male gender [3.72 (1.27–10.90)], uncontrolled disease [OR = 6.28 (1.80–21.95), for pts with newly diagnosed disease and OR = 5.33 (1.45–19.47), for those with recurrence/progression, sepsis [OR = 5.31 (1.62–17.37)] and AOF [OR = 2.35 (1.53–3.61)]. Conclusions: Higher age, male gender, the severity of organ failures, sepsis and disease status were the main adverse factors. Type of lymphoma and neutropenia had no impact in the outcome. The appropriate use of such easily available clinical characteristics may avoid forgoing intensive care for lymphoma pts with a chance of survival. No significant financial relationships to disclose.
