  • Title: Veno-occlusive disease of the liver in children with solid tumors undergoing autologous hematopoietic progenitor cell transplantation: a high incidence in patients with neuroblastoma.
    Author: Horn B, Reiss U, Matthay K, McMillan A, Cowan M.
    Journal: Bone Marrow Transplant; 2002 Mar; 29(5):409-15. PubMed ID: 11919731.
    Abstract:
    We retrospectively analyzed the incidence and risk factors for veno-occlusive disease (VOD) in 83 consecutive children with solid tumors, who underwent autologous blood or bone marrow (BM) transplantation at UCSF between 1992 and 2000. Forty-one patients were diagnosed with neuroblastoma and 42 had another solid tumor (Ewing's sarcoma, soft tissue sarcomas, germ cell tumors, etc). Patients with neuroblastoma were more likely than patients with other solid tumors (ST) to be < or =7 years of age, to have a decreased serum albumin level, and to have received abdominal radiation and surgery prior to transplant. Patients with neuroblastoma received a different conditioning regimen and a purged stem cell product. Twenty patients (24%) developed VOD. VOD was self-limited in 15 (75%) patients and severe in five (25%) patients. Univariate analysis identified the following risk factors for VOD: diagnosis of neuroblastoma (odds ratio 6.1, P < 0.01), abdominal radiation (odds ratio 4.1, P < 0.01), abdominal surgery (odds ratio 4.1, P < 0.01), and age < or =7 years of age (odds ratio 3.3, P = 0.02). Disease status at transplant, intensity of previous chemotherapy, conditioning regimen, progenitor cell source, ALT, AST, albumin level, renal function prior to transplant, or use of amphotericin, growth-factor or heparin during transplant, did not affect the incidence of VOD. On multivariate analysis, only the diagnosis of neuroblastoma remained significant (odds ratio 7.8, P = 0.03). Larger studies of patients with neuroblastoma are necessary in order to confirm our findings and better define the risk factors for VOD development in neuroblastoma patients.
