Toxicities have limited the use of allogeneic hematopoietic cell transplantation (HCT) to younger, medically fit patients. In a canine HCT model, a combination of postgrafting mycophenolate mofetil (MMF) and cyclosporine (CSP) allowed stable allogeneic engraftment after minimally toxic conditioning with low-dose (200 cGy) total-body irradiation (TBI). These(More)
Toxicities of high-dose conditioning regimens have limited the use of conventional unrelated donor hematopoietic cell transplantation (HCT) to younger, medically fit patients. Based on preclinical studies, an HCT approach has been developed for elderly or medically infirm patients with HLA-matched or mismatched unrelated donors. In this study, 52 patients(More)
The full potential of a graft-versus-myeloma effect after allogeneic hematopoietic cell transplantation (HCT) for patients with multiple myeloma (MM) has not been realized because of excessive early transplantation-related mortality (TRM) with conventional HCT. Autologous HCTs have been characterized by almost universal disease recurrences. The current(More)
Apolipoprotein AI-derived (AApoAI) amyloidosis may present either as a non-hereditary form with wild-type protein deposits in atherosclerotic plaques or as a hereditary form due to germline mutations in the APOA1 gene. Currently, more than 50 apoAI variants are known, and 13 are associated with amyloidosis. We describe six patients with AApoAI amyloidosis(More)
A hematopoietic cell transplantation (HCT) approach was developed for elderly or ill patients with hematologic malignancies that employed nonmyeloablative conditioning to avoid common regimen-related toxicities and relied on graft-versus-tumor effects for control of malignancy. Eighty-nine patients, median age 53 years, were given fludarabine (90 mg/m2) and(More)
The purpose of this prospective multicenter phase 2 trial was to investigate the long-term outcome of reduced-intensity conditioning allogeneic stem cell transplantation (alloSCT) in patients with poor-risk chronic lymphocytic leukemia. Conditioning was fludarabine/ cyclophosphamide-based. Longitudinal quantitative monitoring of minimal residual disease(More)
The kidney is involved in 70% of patients with immunoglobulin light-chain (AL) amyloidosis, but little is known on progression or reversibility of renal involvement, and criteria for renal response have never been validated. Newly diagnosed patients from the Pavia (n = 461, testing cohort) and Heidelberg (n = 271, validation cohort) centers were included.(More)
Recent literature suggests that after non-myeloablative allogeneic (NMA) stem cell transplantation (SCT), the incidence of extramedullary (EM) relapse in multiple myeloma (MM) patients is increased and that these relapses have a poor prognosis. However, numbers on incidence and treatment outcome are scarce. We collected data from 54 relapsed MM patients(More)
The feasibility of nonmyeloablative stem cell transplantation (NST) was evaluated in 22 adults with high-risk ALL. 16/22 patients had advanced disease and 11/22 had Ph+ ALL. Eleven patients received NST as first stem cell transplantation (SCT). Eleven patients had relapses after allogeneic or autologous SCT and underwent a salvage NST. 18/22 patients (82%)(More)
High-dose cyclophosphamide (HD-CY) has been shown to decrease the tumor mass in multiple myeloma (MM) patients and to be effective in the mobilization of PBPC. By administering hematopoietic growth factor the quantity of progenitor cells in the peripheral blood increased and the hematological toxicity of CY could be reduced. Thirty-two patients with stage(More)
