Abstract 11514: Extracorporeal Membrane Oxygenation is a Feasible Life Saving Modality for Adult Patients With Neoplasms- Outcomes and Trends in the Last Two Decades

Abstract

Introduction: Extracorporeal Membrane Oxygenation (ECMO) is utilized in the management of severe respiratory and circulatory failure. Advanced malignancy is a relative contraindication but the indication for ECMO in the oncologic population has not been clearly established due to the wide spectrum of malignant disease and prognoses. Hypothesis: ECMO is a feasible treatment modality in selected adult oncologic population. Method: The Extracorporeal Life Support Organization (ELSO) database was queried for patients older than 18 years with an International Classification of Diseases (ICD) code of neoplasm over the past two decades (2000-2019). The data were divided into two decades to analyze and compare the trends with background and outcomes. Results: One thousand, six hundred, and ninety-seven patients met inclusion criteria from the last decade which is more than 15 times the number from the previous decade (n=110). Compared with the previous decade, ECMO was used more in patients with older age (56 vs 50.5 years old; p<0.001), cardiac and extracorporeal cardiopulmonary resuscitation (ECPR) support type (p = 0.001), higher P/F ratio (79.0 vs 61.8; p=0.001), and lower oxygenation index (23.0 vs 35.6; p< 0.001) in the last decade. Although survival did not show significant improvement overall (38.9% [660 of 1697] vs 33.6% [37 of 110]; p=0.272), survival in pulmonary ECMO has significantly improved in the last decade (41.6% [409 of 983] vs 29.1% [23 of 79]; p=0.030). Diagnosis of hematologic malignancy, ECPR, and hematopoietic stem cell transplant were identified as predictors of poor prognosis (p = 0.025, <0.001, and 0.021 respectively). Conclusion: Utilization of ECMO for patients with neoplasms has increased over time mirroring the overall increase of adult ECMO. With careful patient selection, ECMO can be successful in oncologic population.
