Mothers with cancer report guilt associated with failing to successfully balance their parental roles and cancer. This study utilized a cross-sectional mixed-methods design and intersectional framework to investigate the multiple roles that mothers with cancer assume and their perceived coping ability. Participants included mothers diagnosed with any type or stage of cancer, in treatment or ≤3 years post-treatment, and experiencing cancer-related disability with a dependent child (

Social determinants of health, including poverty, contribute significantly to health outcomes in the United States; however, their impact on pediatric hematopoietic cell transplantation (HCT) outcomes is poorly understood. We aimed to identify the association between neighborhood poverty and HCT outcomes for pediatric allogeneic HCT recipients in the Center for International Blood and Marrow Transplant Research database. We assembled 2 pediatric cohorts undergoing first allogeneic HCT from 2006 to 2015 at age ≤18 years, including 2053 children with malignant disease and 1696 children with nonmalignant disease. Neighborhood poverty exposure was defined a priori per the US Census definition as living in a high-poverty ZIP code (≥20% of persons below 100% federal poverty level) and used as the primary predictor in all analyses. Our primary outcome was overall survival (OS), defined as the time from HCT until death resulting from any cause. Secondary outcomes included relapse and transplantation-related mortality (TRM) in malignant disease, acute and chronic graft-versus-host disease, and infection in the first 100 days post-HCT. Among children undergoing transplantation for nonmalignant disease, neighborhood poverty was not associated with any HCT outcome. Among children undergoing transplantation for malignant disease, neighborhood poverty conferred an increased risk of TRM but was not associated with inferior OS or any other transplantation outcome. Among children with malignant disease, a key secondary finding was that children with Medicaid insurance experienced inferior OS and increased TRM compared with those with private insurance. These data suggest opportunities for future investigation of the effects of household-level poverty exposure on HCT outcomes in pediatric malignant disease to inform care delivery interventions.

BACKGROUND: Evidence about the impact of marital status before hematopoietic cell transplantation (hct) on outcomes after hct is conflicting. METHODS: We identified patients 40 years of age and older within the Center for International Blood and Marrow Transplant Research registry who underwent hct between January 2008 and December 2015. Marital status before hct was declared as one of: married or living with a partner, single (never married), separated or divorced, and widowed. We performed a multivariable analysis to determine the association of marital status with outcomes after hct. RESULTS: We identified 10,226 allogeneic and 5714 autologous hct cases with, respectively, a median follow-up of 37 months (range: 1-102 months) and 40 months (range: 1-106 months). No association between marital status and overall survival was observed in either the allogeneic (p = 0.58) or autologous (p = 0.17) setting. However, marital status was associated with grades 2-4 acute graft-versus-host disease (gvhd), p < 0.001, and chronic gvhd, p = 0.04. The risk of grades 2-4 acute gvhd was increased in separated compared with married patients [hazard ratio (hr): 1.13; 95% confidence interval (ci): 1.03 to 1.24], and single patients had a reduced risk of grades 2-4 acute gvhd (hr: 0.87; 95% ci: 0.77 to 0.98). The risk of chronic gvhd was lower in widowed compared with married patients (hr: 0.82; 95% ci: 0.67 to 0.99). CONCLUSIONS: Overall survival after hct is not influenced by marital status, but associations were evident between marital status and grades 2-4 acute and chronic gvhd. To better appreciate the effects of marital status and social support, future research should consider using validated scales to measure social support and patient and caregiver reports of caregiver commitment, and to assess health-related quality of life together with health care utilization. ispartof: CURRENT ONCOLOGY vol:27 issue:6 pages:E596-E606 ispartof: location:Switzerland status: published

Purpose There is increasing recognition that cancer and its treatment can have lasting effects on sexuality. However, most studies focus on breast and reproductive cancers while hematological cancers remain understudied. Only one prior study has acknowledged the existence of sexuality concerns among multiple myeloma (MM) survivors but did not expand upon them. This study explored how diagnosis and treatment of MM may affect sexual expression and also examined patient-provider communication about sexuality. Methods Men and women with MM (N=65) were recruited internationally for an online survey. The survey included open-ended questions about MM-specific barriers to engaging in sexual activity, methods used to adapt to sexual changes, and communication with healthcare providers. Answers to open-ended questions were summarized using a qualitative descriptive approach. Results Participants identified several barriers to sexual activity that may be unique to MM, such as concerns about bone health, infections, and vaginal bleeding and bruising. They also described adapting to sexual challenges by trying sexual medicines/aids, changing their sexual expression, and managing treatment risks. Half of the participants reported speaking to providers about sexuality, with a minority receiving sexual health-related recommendations. Conclusions Participants often faced sexual challenges after diagnosis, many of which may be unique to MM. While some were able to adapt to these changes, sexuality concerns were under-discussed and under-treated by healthcare providers. Proposed suggestions for improving patient-provider communication about sexuality and clinical care are offered based on the gaps identified by participants.

Background The association of community factors and outcomes after hematopoietic cell transplantation (HCT) has not been comprehensively described. Using the County Health Rankings and Roadmaps (CHRR) and the Center for International Blood and Marrow Transplant Research (CIBMTR), this study evaluated the impact of community health status on allogeneic HCT outcomes. Methods This study included 18,544 adult allogeneic HCT recipients reported to the CIBMTR by 170 US centers in 2014-2016. Sociodemographic, environmental, and community indicators were derived from the CHRR, an aggregate community risk score was created, and scores were assigned to each patient (patient community risk score [PCS]) and transplant center (center community risk score [CCS]). Higher scores indicated less healthy communities. The impact of PCS and CCS on patient outcomes after allogeneic HCT was studied. Results The median age was 55 years (range, 18-83 years). The median PCS was -0.21 (range, -1.37 to 2.10; standard deviation [SD], 0.42), and the median CCS was -0.13 (range, -1.04 to 0.96; SD, 0.40). In multivariable analyses, a higher PCS was associated with inferior survival (hazard ratio [HR] per 1 SD increase, 1.04; 99% CI, 1.00-1.08; P = .0089). Among hematologic malignancies, a tendency toward inferior survival was observed with a higher PCS (HR, 1.04; 99% CI, 1.00-1.08; P = .0102); a higher PCS was associated with higher nonrelapse mortality (NRM; HR, 1.08; 99% CI, 1.02-1.15; P = .0004). CCS was not significantly associated with survival, relapse, or NRM. Conclusions Patients residing in counties with a worse community health status have inferior survival as a result of an increased risk of NRM after allogeneic HCT. There was no association between the community health status of the transplant center location and allogeneic HCT outcomes.

Follow-up is integral for hematopoietic cell transplantation (HCT) care to ensure surveillance and intervention for complications. We characterized the incidence of and predictors for being lost to follow-up. Two-year survivors of first allogeneic HCT (10,367 adults and 3865 children) or autologous HCT (7291 adults and 467 children) for malignant/nonmalignant disorders between 2002 and 2013 reported to the Center for International Blood and Marrow Transplant Research were selected. The cumulative incidence of being lost to follow-up (defined as having missed 2 consecutive follow-up reporting periods) was calculated. Marginal Cox models (adjusted for center effect) were fit to evaluate predictors. The 10-year cumulative incidence of being lost to follow-up was 13% (95% confidence interval [CI], 12% to 14%) in adult allogeneic HCT survivors, 15% (95% CI, 14% to 16%) in adult autologous HCT survivors, 25% (95% CI, 24% to 27%) in pediatric allogeneic HCT survivors, and 24% (95% CI, 20% to 29%) in pediatric autologous HCT survivors. Factors associated with being lost to follow-up include younger age, nonmalignant disease, public/no insurance (reference: private), residence farther from the tranplantation center, and being unmarried in adult allogeneic HCT survivors; older age and testicular/germ cell tumor (reference: non-Hodgkin lymphoma) in adult autologous HCT survivors; older age, public/no insurance (reference: private), and nonmalignant disease in pediatric allogeneic HCT survivors; and older age in pediatric autologous HCT survivors. Follow-up focusing on minimizing attrition in high-risk groups is needed to ensure surveillance for late effects. ispartof: BIOLOGY OF BLOOD AND MARROW TRANSPLANTATION vol:26 issue:3 pages:553-561 ispartof: location:United States status: published

Allogeneic hematopoietic cell transplantation (alloHCT) is offered in a limited number of medical centers and is associated with significant direct and indirect costs. The degree to which social and geographic barriers reduce access to alloHCT is unknown. Data from the Surveillance, Epidemiology and End Results Program (SEER) and the Center for International Blood and Marrow Transplant Research (CIBMTR) were integrated to determine the rate of unrelated donor (URD) alloHCT for acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), and myelodysplastic syndrome (MDS) performed between 2000 and 2010 in the 612 counties covered by SEER. The total incidence of AML, ALL, and MDS was determined using SEER, and the number of alloHCTs performed in the same time period and geographic area were determined using the CIBMTR database. We then determined which sociodemographic attributes influenced the rate of alloHCT (rural/urban status, median family size, percentage of residents below the poverty line, and percentage of minority race). In the entire cohort, higher levels of poverty were associated with lower rates of alloHCT (estimated rate ratio [ERR], .86 for a 10% increase in the percentage of the population below the poverty line; P

Assessing patient eligibility for hematopoietic stem cell transplantation (HSCT) remains a complex, multifaceted challenge. Among these challenges, the paucity of comprehensive clinical data to guide decision making remains problematic coupled with unclear trade-offs between patient, disease and local HSCT center factors. Moreover, it is unclear that the modification of poor patient characteristics will improve post-HSCT outcomes. However, the use of Comorbidity Indices and Comprehensive Geriatric Assessments helps meet this challenge, but may be limited by overlapping patient characteristics. The increasing consideration for pre-HSCT psychosocial assessments and interventions remains to be studied. Ultimately, the decision to proceed with a HSCT remains interdisciplinary while considering the available evidence discussed in this review.

Hematopoietic cell transplantation (HCT) is a potentially curative treatment for children and adults with malignant and nonmalignant diseases. Despite increasing survival rates, long-term morbidity after HCT is substantial. Neurocognitive dysfunction is a serious cause of morbidity, yet little is known about neurocognitive dysfunction after HCT. To address this gap, collaborative efforts of the Center for International Blood and Marrow Transplant Research and the European Society for Blood and Marrow Transplantation undertook an expert review of neurocognitive dysfunction after HCT. In this review we define what constitutes neurocognitive dysfunction, characterize its risk factors and sequelae, describe tools and methods to assess neurocognitive function in HCT recipients, and discuss possible interventions for HCT patients with this condition. This review aims to help clinicians understand the scope of this health-related problem, highlight its impact on well-being of survivors, and help determine factors that may improve identification of patients at risk for declines in cognitive functioning after HCT. In particular, we review strategies for preventing and treating neurocognitive dysfunction in HCT patients. Finally, we highlight the need for well-designed studies to develop and test interventions aimed at preventing and improving neurocognitive dysfunction and its sequelae after HCT.

BACKGROUND To evaluate the impact of depression before autologous and allogeneic hematopoietic cell transplantation (HCT) on clinical outcomes posttransplantation. METHODS We analyzed data from the Center for International Blood and Marrow Transplant Research to compare outcomes after autologous (n = 3786) or allogeneic (n = 7433) HCT for adult patients with hematologic malignancies with an existing diagnosis of pre-HCT depression requiring treatment versus those without pre-HCT depression. Using Cox regression models, we compared overall survival (OS) between patients with or without depression. We compared the number of days alive and out of the hospital in the first 100 days post-HCT using Poisson models. We also compared the incidence of grade 2-4 acute and chronic graft-versus-host disease (GVHD) in allogeneic HCT. RESULTS The study included 1116 (15%) patients with pre-transplant depression and 6317 (85%) without depression who underwent allogeneic HCT between 2008 and 2012. Pre-transplant depression was associated with lower OS (hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.04-1.23; P = 0.004) and a higher incidence of grade 2-4 acute GVHD (HR, 1.25; 95% CI, 1.14-1.37; P

Importance Mindfulness-based interventions (MBIs), grounded in mindfulness, focus on purposely paying attention to experiences occurring at the present moment without judgment. MBIs are increasingly used by patients with cancer for the reduction of anxiety, but it remains unclear if MBIs reduce anxiety in patients with cancer. Objective To evaluate the association of MBIs with reductions in the severity of anxiety in patients with cancer. Data Sources Systematic searches of MEDLINE, Embase, Cochrane Central Register of Controlled Trials, CINAHL, PsycINFO, and SCOPUS were conducted from database inception to May 2019 to identify relevant citations. Study Selection Randomized clinical trials (RCTs) that compared MBI with usual care, waitlist controls, or no intervention for the management of anxiety in cancer patients were included. Two reviewers conducted a blinded screening. Of 101 initially identified studies, 28 met the inclusion criteria. Data Extraction and Synthesis Two reviewers independently extracted the data. The Cochrane Collaboration risk-of-bias tool was used to assess the quality of RCTs, and the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline was followed. Summary effect measures were reported as standardized mean differences (SMDs) and calculated using a random-effects model. Main Outcomes and Measures Our primary outcome was the measure of severity of short-term anxiety (up to 1-month postintervention); secondary outcomes were the severity of medium-term (1 to ≤6 months postintervention) and long-term (>6 to 12 months postintervention) anxiety, depression, and health-related quality of life of patients and caregivers. Results This meta-analysis included 28 RCTs enrolling 3053 adults with cancer. None of the trials were conducted in children. Mindfulness was associated with significant reductions in the severity of short-term anxiety (23 trials; 2339 participants; SMD, −0.51; 95% CI, −0.70 to −0.33;I2 = 76%). The association of mindfulness with short-term anxiety did not vary by evaluated patient, intervention, or study characteristics. Mindfulness was also associated with the reduction of medium-term anxiety (9 trials; 965 participants; SMD, −0.43; 95% CI, −0.68 to −0.18;I2 = 66%). No reduction in long-term anxiety was observed (2 trials; 403 participants; SMD, −0.02; 95% CI, −0.38 to 0.34;I2 = 68%). MBIs were associated with a reduction in the severity of depression in the short term (19 trials; 1874 participants; SMD, −0.73; 95% CI; −1.00 to −0.46;I2 = 86%) and the medium term (8 trials; 891 participants; SMD, −0.85; 95% CI, −1.35 to −0.35;I2 = 91%) and improved health-related quality of life in patients in the short term (9 trials; 1108 participants; SMD, 0.51; 95% CI, 0.20 to 0.82;I2 = 82%) and the medium term (5 trials; 771 participants; SMD, 0.29; 95% CI, 0.06 to 0.52;I2 = 57%). Conclusions and Relevance In this study, MBIs were associated with reductions in anxiety and depression up to 6 months postintervention in adults with cancer. Future trials should explore the long-term association of mindfulness with anxiety and depression in adults with cancer and determine its efficacy in more diverse cancer populations using active controls.

Controversy surrounds the question of whether clinical trial participants have better outcomes than comparable patients who are not treated on a trial. We explored this question using a recent large, randomized, multicenter study comparing peripheral blood (PB) with bone marrow transplantation from unrelated donors, conducted by the Blood and Marrow Transplant Clinical Trials Network (BMT CTN). We compared characteristics and outcomes of study participants (n = 494) and nonparticipants (n = 1384) who appeared eligible and received similar treatment without enrolling on the BMT CTN trial at participating centers during the study time period. Data were obtained from the Center for International Blood and Marrow Transplant Research. Outcomes were compared between the 2 groups using Cox proportional hazards regression models. No significant differences in age, sex, disease distribution, race/ethnicity, HLA matching, comorbidities, and interval from diagnosis to hematopoietic cell transplantation were seen between the participants and nonparticipants. Nonparticipants were more likely to have lower performance status, lower risk disease, and older donors, and to receive myeloablative conditioning and antithymocyte globulin. Nonparticipants were also more likely to receive PB grafts, the intervention tested in the trial (66% versus 50%, P < .001). Overall survival, transplantation-related mortality, and incidences of acute or chronic graft-versus-host disease were comparable between the 2 groups though relapse was higher (hazard ratio, 1.22; 95% confidence interval, 1.02 to 1.46; P = .028) in nonparticipants. Despite differences in certain baseline characteristics, survival was comparable between study participants and nonparticipants. The results of the BMT CTN trial appear generalizable to the population of trial-eligible patients.

Introduction In patients with transient thrombocytopenia being treated with high-dose chemotherapy followed by stem cell rescue—haematopoietic stem cell transplantation (HSCT), prophylactic transfusions are standard therapy to prevent bleeding. However, a recent multicentre trial suggests that prophylactic platelet transfusions in HSCT may not be necessary. Additionally, the potential overuse of platelet products places a burden on a scarce healthcare resource. Moreover, the benefit of prophylactic platelet transfusions to prevent clinically relevant haemorrhage is debatable. Current randomised data compare different thresholds for administering prophylactic platelets or prophylactic versus therapeutic platelet transfusions. An alternative strategy involves prescribing prophylactic antifibrinolytic agents such as tranexamic acid to prevent bleeding. Methods and analysis This report describes the design of an open-labelled randomised pilot study comparing the prophylactic use of oral tranexamic acid with platelet transfusions in the setting of autologous HSCT. In 3–5 centres, 100 patients undergoing autologous HSCT will be randomly assigned to either a prophylactic tranexamic acid or prophylactic platelets bleeding prevention strategy-based daily platelet values up to 30 days post-transplant. The study will be stratified by centre and type of transplant. The primary goal is to demonstrate study feasibility while collecting clinical outcomes on (1) WHO and Bleeding Severity Measurement Scale (BSMS), (2) transplant-related mortality, (3) quality of life, (4) length of hospital stay, (5) intensive care unit admission rates, (6) Bearman toxicity scores, (7) incidence of infections, (8) transfusion requirements, (9) adverse reactions and (10) economic analyses. Ethics and dissemination This study is funded by a peer-reviewed grant from the Canadian Institutes of Health Research (201 503) and is registered on Clinicaltrials.gov NCT02650791. It has been approved by the Ottawa Health Science Network Research Ethics Board. Study results will presented at national and international conferences. Importantly, the results of this trial will inform the feasibility and conduct of a larger study. Trial registration number NCT02650791; Pre-results.

Background Current literature suggests that the presence and quality of social support may provide meaningful benefits in overall survival of HCT recipients. Further, studies in general oncology and renal transplantation population suggest that married patients have favorable outcomes. Caregivers of HCT recipients are an important source of both instrumental and emotional support, and a reasonable surrogate for presence of social support. Using data from Center for International Blood and Marrow Transplant Research (CIBMTR), we examined the potential influence of marital status (surrogate for caregiver) at the time of HCT on outcomes of HCT. Methods Patients, >40 years of age who underwent either autologous or allogeneic-HCT from 2008 to 2015 were included. Marital status was defined as either 1) Married, 2) Single, never married, 3) Separated/divorced, and 4) Widowed. The probability of OS at 5 years, Grade 2-4 acute GVHD at 100 days and chronic GVHD at 2 years were estimated as appropriate using the Kaplan-Meier method with the log-rank test used for univariate comparisons. Multivariate analysis was performed to determine the association of marital status with these outcomes, while adjusting for clinical and sociodemographic variables. Results We identified 10,226 allogeneic and 5,714 autologous HCT patients; the median follow-up of survivors was 37 months (range 1-102 months) and 40 months (range 1-106 months) respectively. In the allogeneic population, there were n=7,999 married, n=741 single, n=1,175 separated/divorced and n=311 widowed patients. There were n=4,308, n=478, n=695 and n=233 respectively in the autologous population. The baseline characteristics amongst the 4 groups of marital status were comparable. In the allogeneic population, the 5-year probability of OS, 100-day Grade 2-4 acute GVHD, 2-year probability of chronic GVHD were 38% [95%CI (36-39%)], 16% [95%CI (15-17%)]and 46% [95%CI (45-47%)] respectively; while the 5-year probability of OS in the autologous population was 63% [95%CI (61-64%)]. When compared with married patients, single, separated/divorced and widowed patients were not at an increased risk of death [HR 1.09, 95%CI (0.98-1.2); HR 1.01, 95%CI (0.93-1.09); HR 1.09, 95%CI (0.98-1.2)] in the allogeneic setting. Similarly, there was no association of marital status and OS in the autologous setting [HR 1.10, 95%CI (0.92-1.33); HR 1.17, 95%CI (1.01-1.36); HR 1.08, 95%CI (0.86-1.37)] respectively. In contrast, marital status in the allogeneic setting was associated with an increased risk of grade 2-4 acute GVHD in patients who are divorced/separated as compared to married patients [HR 1.13, 95%CI (1.03-1.24)] but not chronic GVHD [HR 0.90, 95%CI (0.80-1.02); HR 0.94, 95%CI (0.86-1.04); HR 0.82, 95%CI (0.68-0.99)] respectively. We did not identify an interaction between marital status and gender. Conclusions Our data suggest the marital status in patients undergoing either autologous or allogeneic HCT is not associated with overall survival or chronic GVHD, while the risk of acute GVHD maybe increased in patients who are divorced/separated. Taken together, the effect of marital status on post-HCT outcomes is negligible when other patient, disease and transplant variables are considered. Alternatively, marital status maybe an imperfect marker for positive social support. Future research should consider measuring social support using validated scales and assess health related quality of life together with health care utilization outcomes to better appreciate the potential impact of social support.

s / International Journal of Surgery 12 (2014) S13eS117 S69 Methods: We examined all scheduled plastic surgery lists between March and May 2013, using the Galaxy recording system. We found 375 lists with sufficient information for analysis. Results: 81% of lists were delayed, the average delay was 21 minutes, theatre and surgeon categories were the most common reasons for delay, patient and ‘other’ reasons were associated with the longest delays, there was variation between different theatres and wards. Conclusions: Literature and experience suggest 4 potential interventions. Firstly, engagement of a coordinator has greatly reduced delay in hand surgery. This audit justifies such a role for plastic surgery. Secondly, the development and deployment of novel IT technologies. Thirdly, new methods of information dissemination; peer-to-peer teaching, or posters outlining the full patient pathway. Finally, emulating initiatives from industry; aviation or formula one racing. 0090: SPITZ NAEVI IN CHILDREN: 5 YEAR AUDIT IN A PAEDIATRIC HOSPITAL AND PROPOSED MANAGEMENT GUIDELINES Sara Beattie , Jessica Fielding , Rakhee Chawla , Jo McPartland , Sian Falder .

BACKGROUND: Hematopoietic Stem cell Transplantation (HSCT) can negatively impact the psychosocial well-being of the patient. Social support is a complex term that has been variably used to encompass perceived and objective support, including caregiver presence. Social support has been associated with superior psychosocial outcomes; however the influence of social support on HSCT survival remains unclear. We sought to summarize the literature on the influence of social support on HSCT survival. METHODS: MEDLINE, EMBASE, COCHRANE, CINAHL, AND PSYCINFO WERE SEARCHED USING THE FOLLOWING SEARCH CATEGORIES/CONCEPTS: 1) HSCT, 2) Social support, 3) Caregiver, 4) Survival, and 5) Treatment outcomes. RESULTS: We identified 6 relevant studies: 4 publications, 1 dissertation, and 1 abstract. Three studies were retrospective and 3, prospective. Sample size ranged between 92-272 with a mean/median patient age between 30-55 yrs. The duration of follow-up ranged between 13.3-48 months. Social support was measured inconsistently: 2 by retrospective investigator assessment, 2 as patients' perceived support, 1 as caregiver presence, and 1 included caregiver presence and retrospective investigator assessment. The 4 published studies and 1 abstract demonstrate an association between better social support and survival. However, the unpublished dissertation, with the largest sample size found no association. CONCLUSIONS: There is a paucity of evidence examining social support with HSCT survival. Available studies are older, with the most recent publication in 2005. A heterogeneous group of HSCT patients were studied with variable follow-up times. Further, covariates were variably considered in HSCT survival analyses and we suggest that there may be publication bias, given the negative unpublished study with the largest sample size. Prospective studies using validated scales are necessary to better assess the influence of social support on HSCT mortality. Given the potential for improved HSCT survival with better social support, HSCT centres should routinely provide HSCT recipients and their caregivers with enhanced psychosocial services.

Objective: Hematopoietic stem cell transplant (HSCT) is a demanding procedure with associated physical and psychological sequelae that affects patients and their families. Caregivers to HSCT patients not only have to cope with the life-threatening nature of the disease and treatment, but they also have care-giving responsibilities. This study reviews the literature on the psychosocial impact of being a caregiver to a HSCT patient. Methods: A critical review of the literature published before June 2010 was conducted. Databases searched included CINAHL, Medline, PsycInfo, and Academic Search Complete, as well as a comprehensive reference review. Studies that pertained to caregivers of children (under the age of 18) undergoing a HSCT or caregivers to patients with non-hematological malignancies were excluded. Sixteen quantitative research articles and three qualitative research articles were reviewed and analyzed. Results: Caregiver distress is highest pre-transplant and decreases over time, and caregivers display distress levels comparable to or higher than patients' reported distress levels. Predictors of caregiver distress include female gender, elevated subjective burden, and higher patient symptom distress. Caregivers reported uncertainty, fear of the future, juggling patients' needs with their own, and difficulties adapting to role changes; however, they also reported positive aspects to care giving, such as personal growth and developing a more positive relationship with the patient. Conclusions: There are many limitations to the current research and future directions should include both members of the dyad to evaluate the reciprocal relation between caregiver and patient variables, as well as theory-driven research and research with direct clinical applications.

Background: The association of clinical trial participation with outcomes in cancer patients is controversial, with some studies reporting better outcomes for trial participants while others do not. It is possible that the difference in outcomes is due to differences in baseline characteristics of participants and non-participants. The Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0201 trial was a large randomized, multi-center study comparing peripheral blood (PB) with bone marrow (BM) for hematopoietic cell transplantation (HCT) from HLA-matched or 1 allele mismatched unrelated donors (URD) in patients with acute leukemia, chronic myeloid leukemia and myelodysplastic syndromes. The trial reported no significant survival differences between PB and BM; there was decreased risk of graft failure but increased risk of chronic graft-versus-host disease (GVHD) with PB grafts (Anasetti et al NEJM 2012). Methods: We compared characteristics of BMT CTN 0201 study participants (n=494) with HCT recipients who did not participate on the trial (n=1384) but were potentially eligible by virtue of known characteristics. These patients received similar conditioning and GVHD prophylaxis as trial participants at 38 United States trial centers during the study time-period. Centers that had no eligible non-trial participants were excluded. Outcomes between patients on and off trial were compared using Cox proportional hazards regression models. Data were obtained from the Center for International Blood and Marrow Transplant Research (CIBMTR) that collects patient data on all trial and non-trial allogeneic HCT recipients through its registry function. Results: Approximately 29% [494/1878] of apparently eligible patients were randomized and analyzed as part of the trial. There were no significant differences between study participants and non-participants in age or sex distribution, disease types, HLA or sex matching, comorbidities, or interval from diagnosis to HCT. Higher proportions of non-participants were Hispanic, had a lower performance status and lower disease risk, and received myeloablative conditioning and antithymocyte globulin (ATG) or Campath than the study participants. PB was used more commonly as the graft source in the non-participants as compared to the study participants (65% vs. 50%, p Conclusion: Approximately 29% of patients who appeared eligible and were treated with conditioning and GVHD prophylaxis regimens allowed on the trial were enrolled. Despite some differences in clinical characteristics, most of the outcomes of non-trial participants were comparable to trial participants, suggesting that there is no definitive evidence that the outcomes of patients in a clinical trial are superior to those of the non-participants treated in a similar fashion. The comparable outcomes also indicate that the results of this trial were not seriously affected by selection bias and are therefore representative of the larger population.
