A 54-Year-Old Woman with Donor Cell Origin of Multiple Myeloma after Allogeneic Hematopoietic Stem Cell Transplantation for the Treatment of CML
Chronic myeloid leukemia is a myeloproliferative disorder that may be treated with hematopoietic stem cell transplantation (HSCT). While posttransplantation relapse of disease resulting from a failure to eradicate the patient’s original leukemia could occur, patients may also rarely develop a secondary malignancy or myelodysplastic syndrome (MDS) of donor origin termed donor cell leukemia (DCL). Cases of donor-derived acute myeloid leukemia (AML) or MDS after HSCT or solid tumor transplantation have been published. However, very few cases of donor-derived multiple myeloma (MM) exist. We describe a patient who developed a donor-derived MM following allogeneic HSCT from a sibling donor

Graft-versus-host disease of the skin: life and death on the epidermal edge
AbstractDespite impressive advances in the field of allogeneic hematopoietic transplantation, graft versus host disease (GVHD) remains a significant obstacle to be overcome; it would enhance the safety and efficacy of this life-saving therapy. This review provides a framework for understanding the molecular and cellular basis underlying GVHD. We propose a 3-phase model of GVHD that highlights the importance of the conditioning regimen on the recipient tissues administered prior to infusion of donor bone marrow inoculum. A novel skin explant model, designed to take into consideration the immunobiological consequences of conditioning regimens on resident host cells, is proposed to advance our understanding of GVHD and serve as a potential prognostic tool when allogeneic recipient/donor combinations are being contemplated in the clinic. Within this review, specific emphasis is placed on the importance of defining the apoptotic machinery engaged in epidermal keratinocytes triggered by both conditioning regimens, and by host resident and recruited immunocytes and soluble mediators produced at sites of injury. The review is completed with a working model for cutaneous GVHD. Although the skin is highlighted because of its accessibility for clinical observations and serial sampling opportunities, lessons learned from studies of cutaneous GVHD are likely to provide valuable insights into GVHD occurring in the gastrointestinal tract, lung, and liver. With new insights designed to better predict and prevent GVHD and novel agents designed to treat GVHD, overcoming this current impediment to successful bone marrow transplantation should become increasingly feasible
Randomized Phase III Trial of Pegfilgrastim versus Filgrastim after Autologus Peripheral Blood Stem Cell Transplantation
Nonrandomized trials suggest that pegfilgrastim, a pegylated granulocyte colony-stimulating factor, could be used in lieu of filgrastim after autologus peripheral blood stem cell transplantation. This phase III, randomized, double-blinded, placebo-controlled trial compared the efficacy, costs, and safety of single-dose pegfilgrastim (single 6mg dose) versus daily filgrastim (5μg/kg/day) for this indication. Seventy-eight patients, matched for age, sex, underlying disease, stage, and CD34/kg transplant dose were enrolled. Cytokines were started on day +1 posttransplant and continued to an absolute neutrophil count (ANC) of 5×109/L for 3 days or 10×109/L for 1 day. The median time to neutrophil engraftment (ANC >1.5×109/L for 3 days or 5×109/L for 1 day) was the same in both groups (12 days). No differences in platelet engraftment (11 versus 13 days), number of platelet transfusions (5 versus 4), percent with positive cultures for bacterial pathogens (23% versus 15%), days of fever (1 versus 2), deaths prior to engraftment (1 versus 1), or duration of hospital stay (19 versus 19 days) were seen between the pegfilgrastim and filgrastim groups, respectively. Using the average wholesale price for doses used in this trial, there was a per-patient savings of $961 for the pegfilgrastim group (P < .001). This phase III study failed to demonstrate a difference in time to neutrophil engraftment or any clinical sequelae between pegfilgrastim and filgrastim when given post-APBSCT, with pegfilgrastim achieving a cost savings over filgrastim
rapid and robust cd4 and cd8 t nk b cell dendritic cell and monocyte reconstitution after nicotinamide expanded cord blood transplantation
Introduction Nicotinamide-expanded cord blood (NiCord) is a potential alternative source for allogeneic hematopoietic cell transplantation (HCT) when an HLA-id donor is lacking. A phase 1/2 trial with standalone NiCord HCT showed rapid neutrophil- (11 days) and platelet engraftment (34 days). We previously reported that successful CD4+ immune reconstitution (IR) is crucial for infectious and relapse control associated with favorable survival (JACI 2017) and is a better predictor for event-free survival than neutrophil reconstitution. We performed unique in-depth immune monitoring to evaluate and compare IR after NiCord and conventional HCT. Methods In this phase1/2 international multicenter trial, we compared IR after NiCord HCT to cohorts of adolescent and young adult (AYA) patients receiving either unmanipulated cord blood transplantation (unCBT) or T-repleted-unrelated bone marrow transplantation (BMT). All patients received HCT for a hematologic malignancy with myeloablative conditioning without serotherapy. Immune monitoring was performed (harmonized sampling, handling and analyses) in a central lab. The primary endpoint was probability of achieving CD4+ IR (>50*106/L within 100 days). Secondary endpoints were IR of B-cells, CD4+ and CD8+ T-cells, natural killer (NK)-cells, monocytes, and dendritic cells (DC) 7-365 days after HCT. In addition, TREC analyses were performed on CD3+ MACs-sorted cells. Linear-mixed effects modelling in LOESS-regression curves and two-sided log-rank test for univariate comparisons in cumulative incidence plots were used. Results 27 NiCord recipients (median 41.5; 13.4-61.7yrs) were included. NiCord cell dose consisted of median 6.4*106 CD34+/kg, and 2.3*106 CD3+T-cells/kg of the co-infused negative fraction (following CD133+ selection). Of these patients, 91% achieved successful CD4+ IR, which was comparable (p=0.76, Figure 1) to the 27 unCBT (median 15.4; 12.2-22.1 yrs) and 20 BMT (median 14.3; 12.1-19.7 yrs) recipients included in this study. We observed similar reconstitution of T-cells (p=0.15), monocytes (p=0.94), conventional DCs (p=0.41), and plasmacytoid DCs (p=0.52). Interestingly, reconstitution of NK-cells (p Conclusions In-depth immune monitoring reveals fast and full IR after NiCord HCT in adult patients, which is equal or even faster to IR after unCBT or BMT, despite the younger age of the AYA cohorts (expected to reconstitute faster). This may be explained by the higher stem cell dose and higher proliferative capacity of the NiCord-expanded product. Optimal comparison of IR in NiCord vs. unCBT in a randomized phase 3 trial is underway
Palifermin for oral mucositis after intensive therapy for hematologic cancers
BACKGROUND: Oral mucositis is a complication of intensive chemotherapy and radiotherapy with no effective treatment. We tested the ability of palifermin (recombinant human keratinocyte growth factor) to decrease oral mucosal injury induced by cytotoxic therapy. METHODS: This double-blind study compared the effect of palifermin with that of a placebo on the development of oral mucositis in 212 patients with hematologic cancers; 106 patients received palifermin (60 microg per kilogram of body weight per day) and 106 received a placebo intravenously for three consecutive days immediately before the initiation of conditioning therapy (fractionated total-body irradiation plus high-dose chemotherapy) and after autologous hematopoietic stem-cell transplantation. Oral mucositis was evaluated daily for 28 days after transplantation. RESULTS: The incidence of oral mucositis of World Health Organization (WHO) grade 3 or 4 was 63 percent in the palifermin group and 98 percent in the placebo group (P\u3c0.001). Among patients with this degree of mucositis, the median duration of mucositis was 6 days (range, 1 to 22) in the palifermin group and 9 days (range, 1 to 27) in the placebo group. Among all patients, regardless of the occurrence of mucositis, the median duration of oral mucositis of WHO grade 3 or 4 was 3 days (range, 0 to 22) in the palifermin group and 9 days (range, 0 to 27) in the placebo group (P\u3c0.001). As compared with placebo, palifermin was associated with significant reductions in the incidence of grade 4 oral mucositis (20 percent vs. 62 percent, P\u3c0.001), patient-reported soreness of the mouth and throat (area-under-the-curve score, 29.0 [range, 0 to 98] vs. 46.8 [range, 0 to 110]; P\u3c0.001), the use of opioid analgesics (median, 212 mg of morphine equivalents [range, 0 to 9418] vs. 535 mg of morphine equivalents [range, 0 to 9418], P\u3c0.001), and the incidence of use of total parenteral nutrition (31 percent vs. 55 percent, P\u3c0.001). Adverse events, mainly rash, pruritus, erythema, mouth and tongue disorders, and taste alteration, were mild to moderate in severity and were transient. CONCLUSIONS: Palifermin reduced the duration and severity of oral mucositis after intensive chemotherapy and radiotherapy for hematologic cancers
Outcomes of MYC-associated lymphomas after R-CHOP with and without consolidative autologous stem cell transplant: subset analysis of randomized trial intergroup SWOG S9704
Double hit lymphoma (DHL) and double protein-expressing (MYC and BCL2) lymphomas (DPL) fare poorly with R-CHOP; consolidative autologous stem cell transplant (ASCT) may improve outcomes. S9704, a phase III randomized study of CHOP +/−R with or without ASCT allows evaluation of intensive consolidation. Immunohistochemical analysis identified 27 of 198 patients (13.6%) with MYC IHC overexpression and 20 (74%) harboring concurrent BCL2 overexpression. Four had DHL and 16 had DPL only. With median follow-up 127 months, there is a trend favoring outcomes after consolidative ASCT in DPL and MYC protein overexpressing patients, whereas all DHL patients have died irrespective of ASCT
