BackgroundMany clinical and demographic factors can influence survival of patients with hematologic malignancies who have intracranial hemorrhages (ICHs). Understanding the influence of these factors on patient survival can guide treatment decisions and may inform prognostic discussions. We conducted a systematic literature review to determine survival of patients with intracranial hemorrhages and concomitant hematologic malignancy.MethodsA systematic literature review was conducted and followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. PubMed/MEDLINE, Web of Science, Ovid, SCOPUS, and Embase databases were queried with the following terms: ("intracranial hemorrhages" OR "brain hemorrhage" OR "cerebral hemorrhage" OR "subdural hematoma" OR "epidural hematoma" OR "intraparenchymal hemorrhage") AND ("Hematologic Neoplasms" OR "Myeloproliferative Disorders" OR "Myelofibrosis" OR "Essential thrombocythemia" OR "Leukemia"). Abstracts and articles were screened according to inclusion and exclusion criteria that were determined a priori.ResultsLiterature review yielded 975 abstracts from which a total of 68 full-text articles were reviewed. Twelve articles capturing 634 unique patients were included in the final qualitative analysis. Median overall survival for all patients ranged from 20 days to 1.5 months while median overall survival for the subset of patients having ICH within 10 days of diagnosis of hematologic malignancy was 5 days. Intraparenchymal hemorrhages, multiple foci of hemorrhage, transfusion-resistant low platelet counts, leukocytosis, low Glasgow Coma Scale scores at presentation, and ICH early in treatment course were associated with worse outcomes.ConclusionsSurvival for patients with hematologic malignancies and concomitant ICHs remains poor. Early detection, recognition of poor prognostic factors, and correction of hematologic abnormalities essential to prevention and treatment of ICHs in this patient population.Copyright © 2020 Elsevier Inc.
