    ABSTRACT: Although hematopoietic stem cell transplant (HSCT) patients may experience neurocognitive impairment, experiences of neurobehavioral problems (including apathy and disinhibition) are understudied. These experiences reflect behavioral signs and symptoms of neurological dysfunction that can potentially reduce health-related quality of life (HRQOL). Understanding them is important because they may be confused with other diagnoses, including depression, potentially leading to inappropriate treatments. The objectives of this preliminary cross-sectional study were to describe HSCT patients' neurobehavioral functioning pre-HSCT and post-HSCT and to examine relations with HRQOL.

    ABSTRACT: Allogeneic hematopoietic cell transplantation (alloHCT) with reduced intensity conditioning is an appealing option for patients with high risk multiple myeloma (MM). However, progression after alloHCT remains a challenge. Maintenance therapy after alloHCT may offer additional disease control and allow time for a graft-versus-myeloma effect. The primary objective of this clinical trial was to determine the tolerability and safety profile of maintenance lenalidomide (LEN) given on days 1-21 of 28 days cycles, with intra-patient dose escalation during 12 months/cycles after alloHCT. Thirty alloHCT recipients (median age 54 years) with high risk MM were enrolled at 8 centers between 2009 -2012. The median time from alloHCT to LEN initiation was 96 days (66-171 days). Eleven patients (37%) completed maintenance and 10 mg daily was the most commonly delivered dose (44%).Most common reasons for discontinuation were aGVHD (37%) and disease progression (37%). Cumulative incidence of grades III-IV acute GVHD from time of initiation of Len was 17%. . Outcomes at 18 months after initiation of maintenance were MM progression, 28%; transplant related mortality, 11%; and progression-free and overall survival, 63% and 78%, respectively. The use of LEN post alloHCT is feasible at lower doses, although associated with a 38% incidence of aGVHD. Survival outcomes observed in this high risk MM population warrant further study of this approach.

    ABSTRACT: Relapsed/refractory diffuse large B-cell lymphoma (DLBCL) is associated with a poor prognosis. Outcomes are particularly poor following immunochemotherapy failure or relapse within 12 months of induction. We conducted a Phase I/II trial of lenalidomide plus RICE (rituximab, ifosfamide, carboplatin, and etoposide) (RICER) as a salvage regimen for first-relapse or primary refractory DLBCL. Dose-escalated lenalidomide was combined with RICE every 14 d. After three cycles of RICER, patients with chemosensitive disease underwent stem cell collection and consolidation with BEAM [BCNU (carmustine), etoposide, cytarabine, melphalan] followed by autologous stem cell transplantation (autoSCT). Patients who recovered from autoSCT toxicities within 90 d initiated maintenance treatment with lenalidomide 25 mg daily for 21 d every 28 d for 12 months. No dose-limiting or unexpected toxicities occurred with lenalidomide 25 mg plus RICE. Grade 3/4 haematological toxicities resolved appropriately, and planned dose density and dose intensity of RICER were preserved. No lenalidomide or RICE dose reductions were required in any of the three cycles. After two cycles of RICER, nine of 15 patients (60%) achieved a complete response, and two achieved a partial response (13%). Combining lenalidomide with RICE is feasible, and results in promising response rates (particularly complete response rates) in high-risk DLBCL patients.

    ABSTRACT: Objective: Prior research supports the hypothesis that cancer survivors who help others face treatment experience a range of psychosocial and health-related benefits as a result of peer helping. This study investigates an expressive helping (EH) intervention designed to harness those benefits by targeting survivorship problems among cancer survivors treated with hematopoietic stem cell transplant. EH includes two components: (a) emotionally expressive writing (EW; writing one's deepest thoughts and feelings about the transplant experience in a series of brief, structured writing sessions) followed by (b) peer helping (PH; helping other people prepare for transplant by sharing one's own transplant experiences along with advice and encouragement through a written narrative). Method: EH was compared with neutral writing (NW), EW (without PH), and PH (without EW) in a 4-arm randomized controlled trial in which survivors completed baseline measures, 4 structured writing exercises (with instructions depending on randomization), and postintervention measures including validated measures of general psychological distress, physical symptoms, and health-related quality of life (HRQOL). Results: Among survivors with moderate-severe survivorship problems, EH reduced distress (compared with NW and PH; ps < .05) and improved physical symptoms (compared with NW, PH, and EW; ps < .002) and HRQOL (compared with NW; p = .02). Conclusions: Peer helping through writing benefits transplant survivors with moderate-severe survivorship problems, but only if they have first completed expressive writing.

    ABSTRACT: Hematopoietic stem cells can be procured from unrelated donors via either the bone marrow (BM) aspiration or peripheral blood stem cell (PBSC) collection methods. There is no evidence from prospective randomized trials in the unrelated donor setting about the relative health-related quality-of-life (HRQoL) benefits/costs to donors. The goals of this prospective longitudinal investigation were to describe and compare the donation-related HRQoL experiences of 332 BM and PBSC donors. Donors were interviewed before donation, 48 hours after donation, weekly until fully recovered, and at 6 and 12 months after donation. Before donation, BM donors had lower confusion, fewer concerns, and were more prepared for donation. Shortly after donation, BM donors reported more physical side effects. BM donors also reported more donation-related impact on their social activities. However, BM donors reported somewhat better psychological status and were more likely to indicate that the donation made their lives more meaningful. There were virtually no longer term differences in the experiences of the 2 donor groups, including no recovery time difference beginning 3 weeks after donation. Although BM donors may experience the process as more physically stressful and more psychologically beneficial in the short term, the longer term HRQoL consequences of BM and PBSC donors are similar.

    ABSTRACT: The use of available antiviral agents for the prevention of cytomegalovirus (CMV) disease is limited by frequent toxic effects and the emergence of resistance. CMX001 has potent in vitro activity against CMV and other double-stranded DNA viruses. We evaluated the safety and anti-CMV activity of CMX001 in patients who had undergone allogeneic hematopoietic-cell transplantation. From December 2009 through June 2011, a total of 230 patients with data that could be evaluated were enrolled in the study. We randomly assigned these adult CMV-seropositive transplant recipients from 27 centers to oral administration of CMX001 or placebo. Patients were assigned in a 3:1 ratio to five sequential study cohorts according to a dose-escalating, double-blind design. Randomization was stratified according to the presence or absence of acute graft-versus-host disease and CMV DNA in plasma. Patients received the study drug after engraftment for 9 to 11 weeks, until week 13 after transplantation. Polymerase-chain-reaction analysis of CMV DNA in plasma was performed weekly. Patients in whom CMV DNA was detected at a level that required treatment discontinued the study drug and received preemptive treatment against CMV infection. The primary end point was a CMV event, defined as CMV disease or a plasma CMV DNA level greater than 200 copies per milliliter when the study drug was discontinued. The analysis was conducted in the intention-to-treat population. The incidence of CMV events was significantly lower among patients who received CMX001 at a dose of 100 mg twice weekly than among patients who received placebo (10% vs. 37%; risk difference, -27 percentage points; 95% confidence interval, -42 to -12; P=0.002). Diarrhea was the most common adverse event in patients receiving CMX001 at doses of 200 mg weekly or higher and was dose-limiting at 200 mg twice weekly. Myelosuppression and nephrotoxicity were not observed. Treatment with oral CMX001 at a dose of 100 mg twice weekly significantly reduced the incidence of CMV events in recipients of hematopoietic-cell transplants. Diarrhea was dose-limiting in this population at a dose of 200 mg twice weekly. (Funded by Chimerix; CMX001-201 ClinicalTrials.gov number, NCT00942305.).

    ABSTRACT: Virus-specific T-cell lines could provide useful antiviral prophylaxis and treatment for immune-deficient patients if it were possible to avoid the necessity of generating a separate line for each patient, often on an emergency basis. We prepared a bank of 32 virus-specific lines from individuals with common HLA polymorphisms who were immune to Epstein-Barr virus, cytomegalovirus or adenovirus. Eighteen lines were administered to 50 patients with severe, refractory illness due to infection with one of these viruses after hematopoietic stem cell transplant. The cumulative rates of complete or partial responses at 6 weeks post-infusion were: 74.0% (95% CI: 58.5%-89.5%) for the entire group (n=50), 73.9% (51.2-96.6%) for cytomegalovirus (n=23), 77.8% for adenovirus (n=18), and 66.7% (36.9-96.5%) for Epstein-Barr virus (n=9). Only four responders had a recurrence or progression. There were no immediate infusion-related adverse events, and only two subjects developed de-novo graft-versus-host disease. Despite the disparity between the lines and their recipients, the mean frequency of virus-specific T-cells rose significantly post-infusion, coincident with striking decreases in viral DNA and resolution of clinical symptoms. The use of banked third-party virus-specific T-cells is a feasible and safe approach to rapidly treat severe or intractable viral infections after stem cell transplantation.

    ABSTRACT: In experimental models, ex vivo induced T cell rapamycin-resistance occurred independent of T-helper 1 (Th1)/T-helper 2 (Th2) differentiation and yielded allogeneic CD4(+) T cells of increased in vivo efficacy that facilitated engraftment and permitted graft-versus-tumor (GVT) effects while minimizing graft-versus-host disease (GVHD). To translate these findings, we performed a phase II multi-center clinical trial of rapamycin-resistant donor CD4(+) Th2/Th1 (T-Rapa) cells after allogeneic matched-sibling donor hematopoietic cell transplantation (HCT) for therapy of refractory hematologic malignancy. T-Rapa cell products, which expressed a balanced Th2/Th1 phenotype, were administered as a pre-emptive donor lymphocyte infusion (DLI) at day 14 post-HCT. After T-Rapa cell infusion, mixed donor/host chimerism rapidly converted and there was preferential immune reconstitution with donor CD4(+) Th2 and Th1 cells relative to regulatory T cells and CD8(+) T cells. The cumulative incidence probability of acute GVHD was 20% and 40% at days 100 and 180 post-HCT, respectively. There was no transplant-related mortality. Eighteen of 40 patients (45%) remain in sustained complete remission (range of follow-up: 42 to 84 months). These phase II clinical trial results demonstrate the safety of this low-intensity transplant approach, and indicate the feasibility of subsequent randomized studies to compare T-Rapa cell-based therapy to standard transplantation regimens.

    ABSTRACT: Randomized trials have shown that the transplantation of filgrastim-mobilized peripheral-blood stem cells from HLA-identical siblings accelerates engraftment but increases the risks of acute and chronic graft-versus-host disease (GVHD), as compared with the transplantation of bone marrow. Some studies have also shown that peripheral-blood stem cells are associated with a decreased rate of relapse and improved survival among recipients with high-risk leukemia. We conducted a phase 3, multicenter, randomized trial of transplantation of peripheral-blood stem cells versus bone marrow from unrelated donors to compare 2-year survival probabilities with the use of an intention-to-treat analysis. Between March 2004 and September 2009, we enrolled 551 patients at 48 centers. Patients were randomly assigned in a 1:1 ratio to peripheral-blood stem-cell or bone marrow transplantation, stratified according to transplantation center and disease risk. The median follow-up of surviving patients was 36 months (interquartile range, 30 to 37). The overall survival rate at 2 years in the peripheral-blood group was 51% (95% confidence interval [CI], 45 to 57), as compared with 46% (95% CI, 40 to 52) in the bone marrow group (P=0.29), with an absolute difference of 5 percentage points (95% CI, -3 to 14). The overall incidence of graft failure in the peripheral-blood group was 3% (95% CI, 1 to 5), versus 9% (95% CI, 6 to 13) in the bone marrow group (P=0.002). The incidence of chronic GVHD at 2 years in the peripheral-blood group was 53% (95% CI, 45 to 61), as compared with 41% (95% CI, 34 to 48) in the bone marrow group (P=0.01). There were no significant between-group differences in the incidence of acute GVHD or relapse. We did not detect significant survival differences between peripheral-blood stem-cell and bone marrow transplantation from unrelated donors. Exploratory analyses of secondary end points indicated that peripheral-blood stem cells may reduce the risk of graft failure, whereas bone marrow may reduce the risk of chronic GVHD.

    ABSTRACT: BACKGROUND: Hematopoietic stem cell transplantation is a demanding cancer treatment associated with enduring physical and psychological complications. Survivors' well-being may be further compromised by exposure to chronic stressors common to this population, including difficulties arising from costly medical care, changes in employment status, and health insurance coverage. Thus, we hypothesized that financial, employment, and insurance stressors (collectively referred to as economic survivorship stressors) would be associated with poorer health-related quality of life (HRQOL) among hematopoietic stem cell transplantation survivors. METHODS: Survivors (n = 181; M = 640 days post-transplant) completed the measures of study variables through mailed questionnaires and telephone interviews. Hierarchical regression analyses were conducted to test the hypothesized associations between economic survivorship stressors and HRQOL, and to examine whether social and situational factors interact with survivors' stress perceptions to predict HRQOL. RESULTS: Greater financial and employment stress were associated with poorer functioning across multiple HRQOL domains, even after controlling for the effects of possible confounding sociodemographic and medical variables. Insurance stress was not associated with HRQOL. Some associations were moderated by situational factors including timing of the current financial crisis and portion of the transplant paid for by health insurance. CONCLUSIONS: Hematopoietic stem cell transplantation survivors can face serious economic challenges during recovery. Results suggest the value of viewing these challenges as chronic stressors capable of reducing survivors' mental and physical well-being. Identifying resources and skills that help survivors cope with these demands is an important goal for clinicians and researchers. Copyright © 2012 John Wiley & Sons, Ltd.

    ABSTRACT: This study investigated whether loneliness and cognitive processing explain the influence of negative (social constraints) and positive (emotional support) relationship qualities on cancer survivors' distress. Participants were 195 cancer survivors who had undergone hematopoietic stem cell transplantation. Path analysis supported the hypothesis that loneliness and cognitive processing would mediate the association between social constraints and distress. Only loneliness mediated the association between emotional support and distress - an indirect effect significant only when support came from family and friends rather than a partner. Findings suggest that addressing social constraints may enhance cancer survivors' adjustment.

    ABSTRACT: Results from two randomized trials have shown that oral beclomethasone dipropionate (BDP) is effective for treatment of acute gastrointestinal graft-versus-host disease. Here, we report results of a double-blind, randomized placebo-controlled phase II study designed to test the hypothesis that acute graft-versus-host disease could be prevented by administration of oral BDP, beginning before hematopoietic cell transplantation and continuing until day 75 after hematopoietic cell transplantation after myeloablative conditioning. Study drug (BDP or placebo) was administered as 1-mg immediate-release formulation plus 1-mg delayed-release formulation orally four times daily. According to the primary endpoint, systemic glucocorticoid treatment for graft-versus-host disease was given to 60 of the 92 participants (65%) in the BDP arm, versus 31 of 46 participants (67%) in the placebo arm. The secondary efficacy endpoints showed no statistically significant differences between the two arms. The proportion of participants who took at least 90% of the prescribed study drug during the first 4 weeks after hematopoietic cell transplantation was 54% overall. Lower severity of mucositis strongly correlated with higher adherence to the schedule of study drug administration. Inconsistent adherence related to mucositis during recovery after myeloablative conditioning may have obscured a beneficial therapeutic effect in the current study.

    ABSTRACT: Autologous haemopoietic stem-cell transplantation (HSCT) improves survival in patients with multiple myeloma, but disease progression remains an issue. Allogeneic HSCT might reduce disease progression, but can be associated with high treatment-related mortality. Thus, we aimed to assess effectiveness of allogeneic HSCT with non-myeloablative conditioning after autologous HSCT compared with tandem autologous HSCT. In our phase 3 biological assignment trial, we enrolled patients with multiple myeloma attending 37 transplant centres in the USA. Patients (<70 years old) with adequate organ function who had completed at least three cycles of systemic antimyeloma therapy within the past 10 months were eligible for inclusion. We assigned patients to receive an autologous HSCT followed by an allogeneic HSCT (auto-allo group) or tandem autologous HSCTs (auto-auto group) on the basis of the availability of an HLA-matched sibling donor. Patients in the auto-auto group subsequently underwent a random allocation (1:1) to maintenance therapy (thalidomide plus dexamethasone) or observation. To avoid enrolment bias, we classified patients as standard risk or high risk on the basis of cytogenetics and β2-microglobulin concentrations. We used the Kaplan-Meier method to estimate differences in 3-year progression-free survival (PFS; primary endpoint) between patients with standard-risk disease in the auto-allo group and the best results from the auto-auto group (maintenance, observation, or pooled). This study is registered with ClinicalTrials.gov, number NCT00075829. Between Dec 17, 2003, and March 30, 2007, we enrolled 710 patients, of whom 625 had standard-risk disease and received an autologous HSCT. 156 (83%) of 189 patients with standard-risk disease in the auto-allo group and 366 (84%) of 436 in the auto-auto group received a second transplant. 219 patients in the auto-auto group were randomly assigned to observation and 217 to receive maintenance treatment, of whom 168 (77%) completed this treatment. PFS and overall survival did not differ between maintenance and observation groups and pooled data were used. Kaplan-Meier estimates of 3-year PFS were 43% (95% CI 36-51) in the auto-allo group and 46% (42-51) in the auto-auto group (p=0·671); overall survival also did not differ at 3 years (77% [95% CI 72-84] vs 80% [77-84]; p=0·191). Within 3 years, 87 (46%) of 189 patients in the auto-allo group had grade 3-5 adverse events as did 185 (42%) of 436 patients in the auto-auto group. The adverse events that differed most between groups were hyperbilirubinaemia (21 [11%] patients in the auto-allo group vs 14 [3%] in the auto-auto group) and peripheral neuropathy (11 [6%] in the auto-allo group vs 52 [12%] in the auto-auto group). Non-myeloablative allogeneic HSCT after autologous HSCT is not more effective than tandem autologous HSCT for patients with standard-risk multiple myeloma. Further enhancement of the graft versus myeloma effect and reduction in transplant-related mortality are needed to improve the allogeneic HSCT approach.

    ABSTRACT: Transplantation of hematopoietic progenitor cells from red cell-incompatible donors occurs in 30-50% of patients. Immediate and delayed hemolytic transfusion reactions are expected complications of red cell-disparate transplantation and both ABO and other red cell systems such as Kidd and rhesus can be involved. The immunohematological consequences of red cell-incompatible transplantation include delayed red blood cell recovery, pure red cell aplasia and delayed hemolysis from viable lymphocytes carried in the graft ('passenger lymphocytes'). The risks of these reactions, which may be abrupt in onset and fatal, are ameliorated by graft processing and proper blood component support. Red blood cell antigens are expressed on endothelial and epithelial tissues in the body and could serve to increase the risk of GvHD. Mouse models indicate that blood cell antigens may function as minor histocompatibility antigens affecting engraftment. Similar observations have been found in early studies of human transplantation for transfused recipients, although current conditioning and immunosuppressive regimens appear to overcome this affect. No deleterious effects from the use of red cell-incompatible hematopoietic grafts on transplant outcomes, such as granulocyte and platelet engraftments, the incidences of acute or chronic GvHD, relapse risk or OS, have been consistently demonstrated. Most studies, however, include limited number of patients, varying diagnoses and differing treatment regimens, complicating the detection of an effect of ABO-incompatible transplantation. Classification of patients by ABO phenotype ignoring the allelic differences of these antigens also may obscure the effect of red cell-incompatible transplantation on transplant outcomes.

    ABSTRACT: OBJECTIVE: Cognitive problems are commonly reported by hematopoietic stem cell transplant (HSCT) survivors and are associated with poorer physical and mental well-being. It was hypothesized that adverse effects of subjective cognitive impairment occur because cognitive difficulties reduce survivors' confidence that they can manage HSCT-related symptoms-that is, self-efficacy for symptom management. METHODS: Hematopoietic stem cell transplant survivors (n = 245), 9 months to 3 years post-HSCT, completed measures of subjective cognitive functioning, self-efficacy for symptom management, and clinically important outcomes: depressed mood, anxiety, and quality of life. Mediation analyses using bootstrapping were conducted to investigate whether effects of subjective cognitive impairment on these outcomes were mediated by self-efficacy for cognitive, emotional (SE-Emotional), social (SE-Social), and physical (SE-Physical) symptom management. RESULTS: Self-efficacy mediated relations between subjective cognitive impairment and depressed mood (total indirect effect = -0.0064 and 95% CI -0.0097 to -0.0036), anxiety (total indirect effect = -0.0045, CI -0.0072 to -0.0021), and quality of life (total indirect effect = 0.0952, CI 0.0901 to 0.2642). SE-Emotional was a unique mediator when the outcome was depressed mood and anxiety. SE-Social, SE-Physical, and SE-Emotional were specific mediators when outcome was quality of life. CONCLUSIONS: Findings support the conclusion that subjective cognitive impairment reduces HSCT survivors' confidence in their ability to manage common post-HSCT symptoms, with implications for physical and mental well-being. Interventions that help enhance survivors' self-efficacy, particularly self-efficacy for the management of emotional symptoms, are likely to benefit HSCT survivors who report subjective cognitive impairment.

    ABSTRACT: Hematopoietic stem cell transplant (HSCT) survivors who are 1 to 3 years posttransplant are challenged by the need to resume valued social roles and activities--a task that may be complicated by enduring transplant-related psychological distress common in this patient population. The present study investigated whether transplant survivors who receive adequate social support from their spouse or intimate partner experience lower distress. Effects of receiving a greater quantity of partner support (a common approach to studying enacted support) were compared with effects of receiving more effective partner support (i.e., support that more closely matches their needs in terms of its quantity and quality). Men and women (N = 230) who were 1 to 3 years posttransplant completed measures of partner support quantity (Manne & Schnoll, 2001), partner social support effectiveness (Rini & Dunkel Schetter, 2010), and psychological distress (Brief Symptom Inventory; Derogatis & Spencer, 1982). Potential medical and sociodemographic confounds were controlled in analyses. As hypothesized, survivors reported less distress when they received more effective partner support (p < .001). Quantity of partner support was not associated with distress (p = .23). An interaction revealed that when partner support was effective, the quantity of support survivors received was not associated with their distress (p = .90); however, when partner support was ineffective, receiving a greater quantity of partner support was associated with substantially elevated distress (p = .002). Findings suggest that clinical approaches to addressing or preventing enduring distress after HSCT should target features of partner support related to its appraised effectiveness.

    ABSTRACT: Clinical trials of chronic graft-versus-host disease (cGVHD) often use early endpoints, such as clinical response at 3 or 6 months, as the primary endpoint instead of measures of long-term treatment success, such as the ability to discontinue immunosuppressive treatment after development of immune tolerance and resolution of active disease. We evaluated the ability of defined overall and organ-specific response categories at 3 and 6 months to predict the subsequent success or failure of primary treatment. The analysis included 116 patients evaluated at 3 months after enrollment and 94 patients evaluated at 6 months after enrollment. Success was defined as withdrawal of systemic treatment after resolution of cGVHD without secondary therapy. Failure was defined as secondary systemic treatment, or death or development of bronchiolitis obliterans during primary treatment. With most definitions, response at 3 months and response at 6 months were not statistically significantly correlated with subsequent success of primary treatment. With some definitions, the absence of response at 6 months had a statistically significant correlation with subsequent failure of primary treatment. These findings suggest that early response to the agents currently used for primary treatment does not necessarily predict subsequent tolerance, an important endpoint in the management of cGVHD. Rigorously defined clinical response is an appropriate primary endpoint for studies of cGVHD, but future clinical trials should provide for extended follow-up to ascertain late outcomes that are not necessarily predictable by evaluation of response before 6 months.
