Risk Score for the Development of Veno-Occlusive Disease after Allogeneic Hematopoietic Cell Transplant.

ABSTRACT: A risk score identifying patients at high risk for veno-occlusive disease (VOD) may aid efforts to study preventive strategies for this uncommon complication of hematopoietic cell transplantation (HCT). Patients receiving a first allogeneic HCT between 2008 and 2013 as reported to the Center for International Blood and Marrow Transplant Research (N?=?13,097) were randomly divided into training and validation sets. Independent prognostic factors for development of VOD by day +100 after HCT were identified with a multivariate logistic regression model. A risk score was constructed in the training set using the significant factors and confirmed in the validation set. Baseline characteristics of the training and validation sets were balanced. In total, 637 patients (4.9%) developed VOD by day +100. Younger age, positive hepatitis B/C serology, lower Karnofsky performance scale score, use of sirolimus, disease, disease status at transplant, and conditioning regimen were independent prognostic factors. Myeloablative conditioning regimens were associated with higher risk of VOD. Busulfan-based myeloablative conditioning regimens guided by pharmacokinetic monitoring were associated with higher risk than those without pharmacokinetic monitoring. Patients were stratified into 4 distinct, statistically significantly different groups by their risk score percentile. This pretransplant risk score successfully stratified allogeneic HCT patients by risk of developing VOD, was validated in an independent set, and demonstrated strong discriminatory ability to identify a high-risk cohort.

Project description:BackgroundSinusoidal obstruction syndrome is a potentially fatal complication following hematopoietic cell transplantation, high-intensity chemotherapies and increasingly seen with calicheamicin based leukemia therapies. Paediatric specific European Society for Blood and Marrow Transplantation (pEBMT) diagnostic criteria have demonstrated benefit in single center studies compared to historic criteria. Yet, the extent to which they have been universally implemented remains unclear.MethodsWe conducted a retrospective multi-centre study to examine the potential impact of the Baltimore, modified Seattle and pEBMT criteria on the incidence, severity, and outcomes of sinusoidal obstruction syndrome among paediatric hematopoietic cell transplantation patients.FindingsThe incidence of sinusoidal obstruction syndrome in this cohort (n = 488) was higher by pEBMT (21.5%) vs historic modified Seattle (15.6%) and Baltimore (7.0%) criteria (p < 0.001). Application of pEBMT criteria identified 44 patients who were not previously diagnosed with sinusoidal obstruction syndrome. Overall, 70.5% of all patients diagnosed with sinusoidal obstruction syndrome ultimately developed very severe disease and almost half of diagnosed patients required critical care support. Overall survival was significantly lower in patients who were diagnosed with sinusoidal obstruction syndrome vs those who were not.InterpretationTaken together, pEBMT criteria may be a sensitive method for prompter diagnosis of patients who subsequently develop severe/very severe sinusoidal obstruction syndrome. To our knowledge, this is the first multi-centre study in the United States (US) to demonstrate that pEBMT guidelines are associated with earlier detection of sinusoidal obstruction syndrome. Since early initiation of definitive treatment for sinusoidal obstruction syndrome has been associated with improved survival in paediatric patients and implementation of pEBMT criteria appears feasible in the US, universal adoption should facilitate prompter diagnosis and lead to improved outcomes of children with sinusoidal obstruction syndrome.FundingNone.
