Cardiac Surgery Outcomes in Patients With Chronic Lymphocytic Leukemia. Academic Article uri icon

Overview

abstract

  • BACKGROUND: Surgical outcomes of patients with chronic lymphocytic leukemia (CLL) undergoing cardiac surgery are limited. Our objectives were to investigate hospital morbidity and mortality after open cardiac surgery in CLL versus non-CLL patients. METHODS: From May 1995 to May 2015, 157 patients with CLL and 55,917 without and older than 47 years underwent elective cardiac surgery at Cleveland Clinic. By Rai criteria, 79 CLL patients (56%) were low risk (class 0), 13 (9.1%) intermediate risk (classes I and II), and 38 (27%) high risk (classes III and IV); 12 (8.5%) were in remission. Mean age of CLL patients was 72 ± 9.0 years, and 18% were women. CLL patients were propensity-score matched to 3 non-CLL patients to compare surgical outcomes. RESULTS: High-risk CLL patients received more blood products than matched non-CLL patients (33/38 [87%] versus 74/114 [65%], p = 0.01), but were less likely to receive cryoprecipitate (0% versus 15/114 [13%], p = .02). Intermediate-risk CLL patients received more platelet units, mean 12 versus 4.6 (p = 0.008). Occurrence of deep sternal wound infection (0% versus 5/471 [1.1%]), septicemia (5/157 [3.2%] versus 14/471 [3.0%]), and hospital mortality (4/157 [2.5%] versus 14/471 [3.0%]) were similar (p > 0.3), independent of prior chemotherapy treatment for CLL. CONCLUSIONS: Although CLL patients did not have higher hospital mortality than non-CLL patients, high-risk CLL patients were more likely to receive blood products. Risks associated with transfusion should be considered when evaluating CLL patients for elective cardiac surgery. Appropriate preoperative management, such as blood product transfusions, and alternative treatment options that decrease blood loss, should be considered for high-risk patients.
