Multicenter StudyDo patients with metastatic and recurrent rhabdomyosarcoma benefit from high-dose therapy with hematopoietic rescue? Report of the German/Austrian Pediatric Bone Marrow Transplantation Group.
Patients with primary metastatic or recurrent rhabdomyosarcoma (RMS) have a very poor prognosis. Since high-dose chemotherapy (HDC) +/- TBI was thought to improve survival, many centers performed this therapy using different types of hematopoietic rescue (auto BM or PBSC, allo BM). This is a retrospective, multi-center analysis of the results of treatment in 36 patients with primary metastatic or relapsed RMS who were given HDC +/- TBI and hematopoietic rescue between 1986 and 1994. ⋯ The tumor recurred in the majority of patients at previously known sites; in three cases new metastatic sites were observed. Patients with primary localized tumors who had been treated with HDC because of relapse did slightly better (four of nine alive with NED) than patients with primary metastatic disease (five of 27 alive with NED). HDC is still of uncertain value in the therapy of poor-risk rhabdomyosarcoma and should be performed only as part of controlled clinical trials.

Multicenter Study Clinical TrialEfficacy of amphotericin B lipid complex injection (ABLC) in bone marrow transplant recipients with life-threatening systemic mycoses.
Bone marrow transplant (BMT) recipients are at increased risk of invasive fungal disease as a result of the profound neutropenia associated with transplantation. Amphotericin B lipid complex injection (ABLC, ABELCET) was developed to preserve the broad spectrum and fungicidal activity of conventional amphotericin B while avoiding its associated nephrotoxicity. ABLC was made available to physicians in an emergency-use program to treat seriously ill patients with advanced fungal infections who had failed to respond to previous systemic antifungal therapy (mostly amphotericin B), had experienced nephrotoxicity or severe acute toxicity due to amphotericin B or other drugs, or had pre-existing renal disease. ⋯ For 30 patients who began ABLC treatment with a serum creatinine > 221 mumol/l, significant reductions were observed at weeks 1 to 3 (P < 0.01) and 6 (P < 0.001). Trends in serum creatinine during ABLC therapy between autologous and allogeneic transplant recipients were similar. In summary, the results of this evaluation indicate that ABLC appears to be less nephrotoxic than conventional amphotericin B as well as an effective treatment for BMT recipients with presumed or confirmed fungal infections.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialGM-CSF accelerates neutrophil recovery after autologous hematopoietic stem cell transplantation.
Patients with non-myeloid hematologic malignancies (including Hodgkin's and non-Hodgkin's lymphomas, myeloma and acute lymphoid leukemia) or solid tumors underwent cytoreductive conditioning regimens followed by either autologous bone marrow transplantation (ABMT) (n = 343) or transplantation of peripheral blood stem cells (PBSC) with (n = 44) or without bone marrow (BM) (n = 16). In a randomized double-blind phase III multi-center trial, patients received either granulocyte-macrophage colony-stimulating factor (GM-CSF, 10 micrograms/kg/day) or placebo by daily i.v. infusion beginning 24 h after bone marrow infusion and continuing until the absolute neutrophil count (ANC) had recovered to > or = 1000/mm3, or for a maximum of 30 days. Median time to neutrophil recovery was significantly shorter in the GM-CSF group (18 vs 27 days, P < 0.001), and more GM-CSF patients had neutrophil recovery by day 30 (70 vs 48%). ⋯ No difference was noted in infection incidence or time to platelet independence. GM-CSF had no negative impact on time to relapse or long-term survival. These data indicate the positive influence of GM-CSF on neutrophil recovery and hospital stay in patients receiving ABMT for a variety of clinical indications.

Multicenter StudyAllogeneic peripheral blood progenitor cell transplantation: analysis of short-term engraftment and acute GVHD incidence in 33 cases. allo-PBPCT Spanish Group.
The results of 33 allogeneic peripheral blood progenitor cells transplants (allo-PBPCT) in adult patients with hematologic malignancies were analyzed in a retrospective and multicenter study. In 21 of 33 cases (63%) the disease was refractory or in advanced stage and eight of the 33 cases (24%) were second transplants after relapse. Donors were treated with a median of 10 (4-16) micrograms/kg/day of rhG-CSF subcutaneously for 5-7 days. ⋯ The quantity of CD34+ cells infused did not significantly affect the engraftment kinetics, from a starting cutoff of 2.5 x 10(6)/kg. The speed of neutrophil recovery seemed to be influenced strongly by using rhG-CSF post-transplant and marginally by the type of GVHD prophylaxis. Actuarial probability for grade II-IV acute GVHD of the whole group was 37% (95% Cl, 20-54%).

Multicenter Study Comparative StudyRetrospective evaluation of autologous bone marrow transplantation vs allogeneic bone marrow transplantation from an HLA identical related donor in acute myelocytic leukemia. A study of the European Cooperative Group for Blood and Marrow Transplantation (EBMT).
We analyzed retrospectively data from 1696 patients with AML transplanted in Europe from January 1987 to December 1992 and reported to the acute leukemia EBMT registry. Groups of patients were analyzed according to age (adults and children) and status at transplant (first remission = CR1; second remission = CR2). (1) 1114 adult patients were transplanted in CR1; 516 received an allograft; 598 received an autograft. Following alloBMT, the transplant-related mortality (TRM) was significantly higher (27 vs 13%, P < 10(-4)), the relapse incidence (RI) lower (25 vs 52%, P < 10(-4)) and the leukemia-free survival (LFS) better (55 vs 42%, P = 0.006). ⋯ These results confirm that both allogeneic and autologous BMT are suitable curative approaches for AML. They favor the use of an HLA identical related allogeneic transplant when available, especially in younger patients, over ABMT with unpurged marrow. The role of purging in ABMT could not be addressed in this study.
