We previously reported that the Charlson Comorbidity Index (CCI) was useful for predicting outcomes in patients undergoing allogeneic hematopoietic cell transplantation (HCT). However, the sample size of patients with scores of 1 or more, captured by the CCI, did not exceed 35%. Further, some comorbidities were rarely found among patients who underwent HCT.(More)
PURPOSE Retrospective studies have shown similar survival among patients with acute myeloid leukemia (AML) and myelodysplasia (MDS) after nonmyeloablative compared with myeloablative conditioning. Refined risk stratification is required to design prospective trials. PATIENTS AND METHODS We stratified outcomes among patients with AML (n = 391) or MDS (n =(More)
Recent studies have suggested that coinfusion of mesenchymal stem cells (MSCs) the day of hematopoietic cell transplantation (HCT) might promote engraftment and prevent graft-versus-host disease (GVHD) after myeloablative allogeneic HCT. This prompted us to investigate in a pilot study whether MSC infusion before HCT could allow nonmyeloablative (NMA) HCT(More)
to the editor: Although secondary cancer is a well-established long-term complication of hematopoi-etic stem-cell transplantation, 1 the transmission of hematologic cancers through marrow or solid-organ transplantation is exceptional. 2 Moreover, to our knowledge, it has not been reported after peripheral-blood stem-cell transplantation. A nine-year-old(More)
PURPOSE We have used a nonmyeloablative conditioning regimen consisting of total-body irradiation (2 Gy) with or without fludarabine (30 mg/m(2)/d for 3 days) for related and unrelated hematopoietic cell transplantation (HCT) in patients with hematologic malignancies who were not candidates for conventional HCT because of age, medical comorbidities, or(More)
We analyzed the kinetics of donor engraftment among various peripheral blood cell subpopulations and their relationship to outcomes among 120 patients with hematologic malignancies given hematopoietic cell transplantation (HCT) after nonmyeloablative conditioning consisting of 2 Gy total body irradiation (TBI) with or without added fludarabine. While(More)
Allogeneic hematopoietic cell transplantation (HCT) was originally developed as a form of rescue from high-dose chemoradiotherapy, which is given both to eradicate malignancy and provide sufficient immunosuppression for allogeneic engraftment. The first attempts of allogeneic HCT in humans met with little success. However, a better understanding of the(More)
BACKGROUND AND OBJECTIVES To maximize graft-versus-leukemia (GVL) effects while minimizing the risk of graft-versus-host disease (GVHD), we undertook a study of allogeneic CD34-selected peripheral blood stem cell (PBSC) transplantation followed by CD8-depleted donor lymphocyte infusion (DLI). DESIGN AND METHODS Twenty-four patients with advanced(More)
Three patients with coexistent Fanconi syndrome and Sweet syndrome (neutrophilic dermatosis) are presented. These sterile skin lesions responded to systemic corticosteroid therapy in all three cases, and recurred when treatment was discontinued. The association in children of Sweet syndrome with malignancy has previously been recognized; it has not been(More)
BACKGROUND AND OBJECTIVE Serum erythropoietin (sEpo) concentration depends primarily on the rate of renal production in response to hypoxia. However, sEpo levels increase inappropriately after conditioning for autologous stem cell transplantation (ASCT) before progressively returning to adequate levels. We investigated the possible influence of(More)
