The aim of this review is to show the importance of occupational therapy/hand therapy for chronic graft-versus-host-disease (GVHD) patients and to outline the current state of the literature. GVHD of the hand can cause functional loss, reduced activities of daily life, poor social interaction, and loss of income because of limitations in work. Hand therapy, which is a specialty practised by both occupational therapists and physical therapists, has been proven to be an effective approach for hand-related musculoskeletal disorders; however, the literature search suggests that it is an underutilized specialty around the world. An electronic search was performed from 1997 to 2017 using OneFile (GALE), Medline/PubMed (NLM), Scopus (Elsevier), Science Citation Index Expanded (Web of Science), ProQuest Central (New), ProQuest Hospital Collection, Health Reference Center Academic (Gale), Health Research Premium Collection, Science Direct Journals (Elsevier), ProQuest Health & Medical Complete, Medical Database, Wiley Online Library, and SciTech Premium Collection for the period from 1994 to April 2017. Only randomized-controlled trials involving occupational therapy or hand therapy in patients with chronic hand GVHD were included in the final analysis. The search was limited to articles in English. Two reviewers independently assessed the methodological quality and extracted the data. The JADAD scoring method was used to score the articles. After the duplicates were excluded, 5466 articles were identified by the electronic database search for screening, out of which 5465 articles were excluded after reviewing. One article was further excluded on obtaining the full text as it was a case study. Hand therapy specialty, although a vital part of the recovery process for the patients with hand GVHD, is an underutilized specialty and well-designed trials are urgently needed for musculoskeletal hand GVHD, especially for focused hand therapy interventions.

BACKGROUNDOutcomes have improved significantly in multiple myeloma (MM), but racial disparities in health care access and survival exist. A comprehensive analysis exploring MM care and racial disparities is warranted.METHODSPatients with MM from 1991 to 2010 in the Surveillance, Epidemiology, and End Results‐Medicare database were evaluated for racial trends in clinical myeloma‐defining events (MDEs), the receipt of treatment (drugs and stem cell transplantation; [SCT]), the cost of care, and overall survival (OS).RESULTSAmong 35,842 patients, the frequency of all MDEs at diagnosis increased over time; whereas, in recent years (2006‐2010), all MDEs with the exception of renal dialysis decreased. Blacks had highest rates for all MDEs except bone fractures, which were highest in whites. Over time, the proportion of patients who received any treatment, multiple agents, and SCT increased significantly, and the largest increase was observed in the receipt of immunomodulatory drugs and steroids. There was greater receipt of bortezomib and SCT among whites and blacks and higher receipt of immunomodulatory drugs among Hispanics and Asians (P < .001). Medicare claims were highest during first 6 months after MM diagnosis for blacks and at any time after MM diagnosis for Hispanics. Over time, Medicare claims increased most steadily for Hispanics (P < .001). Hypercalcemia, renal dysfunction, and bone fractures were associated with inferior OS. Blacks and Asians had superior OS compared with whites, but racial differences in OS became less pronounced during 2006 through 2010 (P = .182) compared with prior years (P < .01). Better OS was noted among patients who had higher median incomes.CONCLUSIONSThe current results indicate that there have been significant changes in the management of patients with MM over time and provide an in‐depth understanding of the factors that may help explain racial disparities.

AbstractOutcomes have improved considerably in multiple myeloma (MM), but disparities among racial‐ethnic groups exist. Differences in utilization of novel therapeutics are likely contributing factors. We explored such differences from the SEER‐Medicare database. A utilization analysis of lenalidomide, thalidomide, bortezomib, and stem cell transplant (SCT) was performed for patients diagnosed with MM between 2007 and 2009, including use over time, use by race, time‐dependent trends for each racial subgroup, and survival analysis. A total of 5338 MM patients were included with median 2.4‐year follow‐up. Within the first year of MM diagnosis, utilization of lenalidomide, bortezomib, SCT, and more than one novel agent increased over time while utilization of thalidomide decreased. There was significantly lower utilization of lenalidomide among African‐Americans (P < 0.01), higher thalidomide use among Hispanics and Asians (P < 0.01), and lower bortezomib use among Asians (P < 0.01). Hispanics had the highest median number of days to first dose of bortezomib (P = 0.02) and the lowest utilization of SCT (P < 0.01). Hispanics and Asians were the only groups without notable increases in lenalidomide and bortezomib use, respectively. SCT utilization increased over time for all except African‐Americans. SCT use within the first year after diagnosis was associated with better overall survival (HR 0.52; 95% CI: 0.4–0.68), while bortezomib use was associated with inferior survival (HR 1.14; 95% CI 1.02–1.28). We noted considerable variability in MM therapeutics utilization with seeming inequity for racial‐ethnic minorities. These trends should be considered to eliminate drug access and utilization disparities and achieve equitable benefit of therapeutic advances across all races.

Hematopoietic cell transplant is a potentially curative procedure for many benign and malignant conditions. The efficacy of allogeneic transplant relies in part on the cytotoxicity of the conditioning regimen and the graft versus tumor effect mediated by alloreactive donor T cells; the same cells are also implicated in the development of graft versus host disease (GVHD). Selective identification and depletion of the T cells implicated in GVHD, while preserving the T cells responsible for graft versus tumor effect has been the focus of many research groups in the recent years. Here we briefly review the physiology of T cells in transplantation, and comment on a recent clinical trial published by Bleakly et al. using a novel way of graft engineered allograft via naïve T cell depletion.

Key Points Over the last decade, allogeneic HCT has been increasingly administered in the United States to adults aged 70 and older with hematologic malignancies. Allogeneic transplant outcomes were reasonable; high comorbidity and ablative conditioning regimens were associated with inferior outcomes.

AbstractObjectiveHLA‐DPB1 matching may impact allogeneic hematopoietic stem cell transplantation (ASCT) outcomes; however, this locus is not in linkage disequilibrium with the remainder of the HLA genes. After classifying HLA‐DPB1 mismatches based on T‐cell epitope, avoiding non‐permissive mismatches may impact survival. We tested this hypothesis at a single academic institution.MethodsRetrospective HLA‐DPB1 genotyping was performed on 153 adult patients who underwent ASCT and unrelated donors matched for HLA‐A, B, C, DRB1, and DQB1 loci (10/10). Using the ImMunoGeneTics/HLA T‐cell epitope matching algorithm, mismatch status was classified as permissive or non‐permissive.ResultsOf 153 donor‐recipient pairs, 22 (14.4%) were HLA‐DPB1 matches, 64 (42.8%) permissive mismatches, and 67 (43.8%) non‐permissive mismatches. DPB1 mismatch increased risk of chronic graft‐versus‐host disease (cGVHD; RR 2.89 [1.19‐9.53], P=.016) compared with DPB1‐matched transplants, but there were no differences in overall mortality, risk of relapse, or acute GVHD (aGVHD). Combining matches and permissive mismatches and comparing to non‐permissive mismatches, there was no significant difference in overall survival or relapse; however, patients receiving non‐permissive mismatched transplants experienced greater risk of aGVHD overall and severe aGVHD (RR 1.66 [1.13‐2.44], P=.010 and RR 1.97 [1.10‐3.59], P=.024, respectively).ConclusionIn this single‐center study, HLA‐DPB1 matching influenced outcomes of patients undergoing ASCT for hematologic malignancy.

BACKGROUNDRace/ethnicity remains an important barrier in clinical care. The authors investigated differences in the receipt of autologous hematopoietic cell transplantation (AHCT) among patients with multiple myeloma (MM) and outcomes based on race/ethnicity in the United States.METHODSThe Center for International Blood and Marrow Transplant Research database was used to identify 28,450 patients who underwent AHCT for MM from 2008 through 2014. By using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results 18 registries, the incidence of MM was calculated, and a stem cell transplantation utilization rate (STUR) was derived. Post‐AHCT outcomes were analyzed among patients ages 18 to 75 years who underwent melphalan‐conditioned peripheral cell grafts (N = 24,102).RESULTSThe STUR increased across all groups from 2008 to 2014. The increase was substantially lower among Hispanics (range, 8.6%‐16.9%) and non‐Hispanic blacks (range, 12.2%‐20.5%) compared with non‐Hispanic whites (range, 22.6%‐37.8%). There were 18,046 non‐Hispanic whites, 4123 non‐Hispanic blacks, and 1933 Hispanic patients. The Hispanic group was younger (P < .001). Fewer patients older than 60 years underwent transplantation among Hispanics (39%) and non‐Hispanic blacks (42%) compared with non‐Hispanic whites (56%). A Karnofsky score <90% and a hematopoietic cell transplantation comorbidity index score >3 were more common in non‐Hispanic blacks compared with Hispanic and non‐Hispanic whites (P < .001). More Hispanics (57%) versus non‐Hispanic blacks (54%) and non‐Hispanic whites (52%; P < .001) had stage III disease. More Hispanics (48%) versus non‐Hispanic blacks (45%) and non‐Hispanic whites (44%) had a very good partial response or better before transplantation (P = .005). Race/ethnicity did not impact post‐AHCT outcomes.CONCLUSIONSAlthough the STUR increased, it remained low and was significantly lower among Hispanics followed by non‐Hispanic blacks compared with non‐Hispanic whites. Race/ethnicity did not impact transplantation outcomes. Efforts to increase the rates of transplantation for eligible patients who have MM, with an emphasis on groups that underuse transplantation, are warranted.

Venous thromboembolism (VTE) contributes to significant morbidity, mortality, and socioeconomic burden. There is a paucity of literature regarding sex-based sociodemographic differences in VTE presentation and short-term outcomes. We aimed to compare clinical outcomes between men and women hospitalized for VTE management. We performed a retrospective analysis using data from the National Inpatient Sample (NIS) database from 2012 to 2013. Inclusion criteria were age 18 years and older and a primary discharge diagnosis of VTE. Sociodemographic features and medical comorbidities were analyzed, as were hospital length of stay and in-hospital mortality rates. A total of 107,896 patients met the inclusion criteria; 53% were female. Median age was 65 years (interquartile range 51–77) and women were older than men (65 vs 62 years, p<0.001). There were significant differences between men and women with respect to race, primary insurance payer and medical comorbidities, and small differences with respect to VTE location. Female sex was associated with a small but significantly longer hospital length of stay (mean ratio 1.04, 95% CI 1.03–1.05, p<0.001) but no significant difference in in-hospital mortality (2.2% vs 2.1%, p=0.15). In a multivariate model, there was no significant difference between women and men with respect to hospital length of stay or in-hospital mortality. In conclusion, we used data from the NIS to study over 100,000 patients hospitalized for VTE, and identified several sex-based disparities in sociodemographic factors and location of VTE. However, in a multivariable analysis correcting for these factors, sex was not associated with significant differences in clinical outcomes.

BACKGROUNDTo evaluate the impact of depression before autologous and allogeneic hematopoietic cell transplantation (HCT) on clinical outcomes post‐transplantation.METHODSWe 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.RESULTSThe 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 < 0.0001), but similar incidence of chronic GVHD. Pre‐transplant depression was associated with fewer days‐alive‐and‐out‐of‐the hospital (means ratio [MR] = 0.97; 95% CI, 0.95‐0.99; P = 0.004). There were 512 (13.5%) patients with Pre‐transplant depression and 3274 (86.5%) without depression who underwent autologous HCT. Pre‐transplant depression in autologous HCT was not associated with OS (HR, 1.15; 95% CI, 0.98‐1.34; P = 0.096) but was associated with fewer days alive and out of the hospital (MR, 0.98; 95% CI, 0.97‐0.99; P = 0.002).CONCLUSIONPre‐transplant depression was associated with lower OS and higher risk of acute GVHD among allogeneic HCT recipients and fewer days alive and out of the hospital during the first 100 days after autologous and allogeneic HCT. Patients with pre‐transplant depression represent a population that is at risk for post‐transplant complications. Cancer 2017;123:1828–1838. © 2017 American Cancer Society.
