BACKGROUND Central nervous system (CNS) atypical teratoid rhabdoid tumors (AT/RT) are rare tumors of childhood with a dismal prognosis. Historically, surgery and standard dose chemotherapy have resulted in a median survival of 8.5 months from diagnosis. METHODS Thirteen children newly diagnosed with CNS AT/RT were treated with either the "Head Start I"(More)
Children with intracranial ependymomas have relatively poor outcomes despite the low-grade histology of these tumors and recent advances in diagnosis, microneurosurgical resection, and adjuvant therapy. Aggressive surgical resection and postoperative adjuvant therapy result in only a 5-year survival rate of 50%. In this paper, we provide a review of the(More)
PURPOSE The goal of this multi-institutional retrospective study of children with intracranial ependymoma was to identify risk factors associated with unfavorable overall survival (OS) and event-free survival (EFS). PATIENTS AND METHODS Clinical data, including demographics, tumor location, spread, histology, details of surgery, radiation treatment, and(More)
Atypical Teratoid/Rhabdoid tumors (AT/RT) of the central nervous system are rare but aggressive tumors of childhood. Median survival with surgery and standard chemotherapy is less than 12 months. In an attempt to improve outcome, patients were treated with aggressive surgical resection and multi-agent chemotherapy, followed by high dose chemotherapy with(More)
PURPOSE To determine the maximum-tolerated dose (MTD) and toxicity of iodine-131-metaiodobenzylguanidine ((131)I-MIBG) with carboplatin, etoposide, melphalan (CEM) and autologous stem-cell transplantation (ASCT) in refractory neuroblastoma. PATIENTS AND METHODS Twenty-four children with primary refractory neuroblastoma and no prior ASCT were entered; 22(More)
PURPOSE To describe recent characteristics of incidence, risk factors, treatment, and outcome of venoocclusive disease (VOD) in children and young adults undergoing blood and bone marrow transplantation (BMT). METHODS All children and young adults (n = 241) undergoing first myeloablative transplant at the UCSF Pediatric BMT unit between 1992 and 2000 were(More)
Adoptive immunotherapy with cytomegalovirus (CMV)-specific cytotoxic T lymphocytes (CTL) is an effective strategy for preventing and treating viral reactivation after allogeneic stem cell transplantation (SCT). We have shown previously that CMV CTL can be generated in 1 to 2 weeks by stimulating donor lymphocytes with peptide mixes derived from full-length(More)
We retrospectively analyzed data on T- and B-cell reconstitution and infectious complications in 58 children undergoing ABMT, in order to evaluate post-transplant supportive care measures used during the study period. Normalization of T-cell number and lymphocyte proliferative responses to phytohemagglutinin (PHA) and alloantigen (MLC) occurred in(More)
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,(More)
We report a high incidence (19.5%) of autoimmune hemolytic anemia (AIHA) in 41 patients with SCID who underwent a T cell-depleted haploidentical transplant. Other than infections, AIHA was the most common post-transplant complication in this patient cohort. Clinical characteristics and treatment of eight patients who developed AIHA at a median of 8 months(More)
