Financial Hardship after Hematopoietic Cell Transplantation: Lack of Impact on Survival.

Background: Financial hardship is a growing challenge for patients with blood cancer who undergo hematopoietic cell transplantation (HCT), and it is associated with poor patient-reported outcomes. In contrast, little is known about the potential impact of patient-reported financial hardship on post-HCT survival.Methods: We sought to describe the association of financial hardship with survival after HCT in a prospectively assembled cohort of patients from three large transplant centers (n = 325).Results: There was no association between financial hardship measures assessed at 6 months post-HCT and 1- or 2-year survival after HCT.Conclusions: Patient-reported financial distress after HCT does not seem to adversely affect post-HCT survival.Impact: When assessing the effectiveness of interventions to ameliorate familial financial burden among HCT, the focus should be on patient-reported outcomes rather than survival.

Readmissions after Umbilical Cord Blood Transplantation and Impact on Overall Survival.

Patients treated with allogeneic hematopoietic stem cell transplantation (SCT) have high rates of readmission, but the incidence after umbilical cord blood transplantation (UCBT) is poorly described. The goal of this study was to identify the incidence and risk factors for readmission after UCBT and the impact of readmission on overall survival (OS). A retrospective review of patients receiving a UCBT at Dana-Farber/Brigham and Women's Hospital between January 1, 2004 and December 31, 2013 was performed. The readmission rates 30 days after discharge from the UCBT admission and at day +100 after the UCBT were examined. Reasons for readmission, as well as sociodemographic, disease-, and SCT-related variables were evaluated. Predictors of readmission and the impact of readmission on OS were identified using multivariate regression analysis. Of patients who received a UCBT, 42 of 126 patients (33.3%) were readmitted within 30 days of discharge and 57 of 123 patients (46.3%) were readmitted by day +100 after transplantation. The most common causes for readmission were infection (38.3%), fever without a source (14.8%), and graft-versus-host disease (8.6%). Infection during the index admission was the only significant risk factor for readmission at both time points in a univariate and multivariate regression analysis (OR, 11.66; 95% CI, 2.77 to 49.13; P < .01 and OR, 5.4; 96% CI, 1.87 to 15.58; P < .01). Prior radiation therapy was also associated with an increased risk of readmission at both time points in the multivariate regression model (OR, 20.6; 95% CI, 3.53 to 120.04; P ≤ .01 and OR, 5; 95% CI, 1.21 to 20.71; P = .03). The multivariate regression model also showed that black race and a median income of <60,000 in the patient's home zip code increased the risk of readmission by day +100 (OR, 30.17; 95% CI, 1.33 to 684.48; P = .03 and OR, 2.88; 95% CI, 1.04 to 7.8; P = .04, respectively). After adjusting for age, disease type, and the disease status at transplant, OS was reduced for the patients who were readmitted by day +100 (HR, 2.44; 95% CI, 1.46 to 4.06; P < .01). There was also a trend toward decreased survival in patients readmitted 30 days after discharge (HR, 1.58; 95% CI, .96 to 2.6; P = .07). Readmissions are common after UCBT. Infections and fever without a source are the most common causes of readmission. Being readmitted by day +100 resulted in a lower 5-year OS rate as compared with patients who were not readmitted. Prior radiation and infection during the transplant admission resulted in increased risk of readmission by 30 days and day +100. Similarly, race and socioeconomic status predicted readmission by day +100. Further understanding of the mechanisms leading to readmissions in these groups may allow for identification of interventions that could reduce readmissions and thus improve mortality.

Validation and refinement of the Disease Risk Index for allogeneic stem cell transplantation.

Because the outcome of allogeneic hematopoietic cell transplantation (HCT) is predominantly influenced by disease type and status, it is essential to be able to stratify patients undergoing HCT by disease risk. The Disease Risk Index (DRI) was developed for this purpose. In this study, we analyzed 13,131 patients reported to the Center for International Blood and Marrow Transplant Research who underwent HCT between 2008 and 2010. The DRI stratified patients into 4 groups with 2-year overall survival (OS) ranging from 64% to 24% and was the strongest prognostic factor, regardless of age, conditioning intensity, graft source, or donor type. A randomly selected training subgroup of 9849 patients was used to refine the DRI, using a multivariable regression model for OS. This refined DRI had improved prediction ability for the remaining 3282 patients compared with the original DRI or other existing schemes. This validated and refined DRI can be used as a 4- or 3-group index, depending on the size of the cohort under study, for prognostication; to facilitate the interpretation of single-center, multicenter, or registry studies; to adjust center outcome data; and to stratify patients entering clinical trials that enroll patients across disease categories.

Finding the right academic job.

The career path in academic medicine is full of exciting opportunities as well as great achievements and discoveries. In this review, we discuss various obstacles that fellows face as they explore career opportunities in academic hematology/oncology. We also share thoughts on what might be considered steps for success in maneuvering through a search for the "right" position. We discuss several aims including how to define career goals early on, keys to success in an academic career, how to look for an academic job, successful points for the interview process, and how to negotiate a job offer. Finally, we discuss some roadblocks and limitations of academic careers and promotions. These limitations, frustrations and roadblocks should not be a deterrent from pursuing such a great role in the scientific field. This is a new generation of scientific discovery, improvement in healthcare and great advances in research.

Individual physician practice variation in hematopoietic cell transplantation.

PURPOSE: Previous studies have evaluated practice variation in hematopoietic cell transplantation (HCT) among transplant centers and countries. There are no studies investigating individual physician practice variation in HCT. METHODS: An international Internet-based survey of transplant physicians collected data on medical decisions made by adult and pediatric HCT physicians. Multivariable analyses identified practitioner and transplant center characteristics predictive of medical decision making. RESULTS: Analysis of 526 assessable respondents showed a wide variation in management approaches to specific clinical scenarios. Pediatric and adult transplant physicians differed significantly in their management strategies for chronic myeloid leukemia, acute and chronic graft-versus-host disease, and choice of graft source for patients with aplastic anemia. Among adult transplant physicians, there was little agreement on the patient factors favoring reduced intensity conditioning or myeloablative conditioning. CONCLUSION: These results emphasize the heterogeneity of worldwide transplant practices. Local preferences or biases likely result in similar patients being offered different transplant and treatment procedures. The degree of practice variation also highlights the need for clinical trials to clarify areas of controversy. Where clinical trials are not feasible, data from observational studies may be the best available evidence to guide practice.

Costs of allogeneic hematopoietic cell transplantation with high-dose regimens.

To characterize the costs of allogeneic hematopoietic cell transplantation with high-dose regimens (HDCT), we analyzed clinical information and costs of 315 HDCT recipients during a 4-year study period beginning in 2000. Multivariate analyses were performed to identify pre- and/or post-HDCT factors predicting higher costs within the first year. Overall survival (OS) at 100 days and 1 year were 80% and 58%, respectively. The median cost and days of hospitalization were $102,574 in 2004 US dollars and 36 days in the hospital for 100 days, and $128,800 and 39 days in the hospital for 1 year. Early costs, defined as costs within the first 100 days, accounted for 84% of total costs within the first year. Inpatient costs comprise 94% of the early costs, but only 61% of the later costs defined as costs incurred between 101 days and 1 year. Of the pre-HDCT factors, unrelated donors and advanced disease risk were significantly associated with increased cost. When post-HDCT events were also considered, these pre-HDCT factors were no longer independently predictive of high cost. Instead, severe complications post-HDCT were associated with higher costs, increasing total costs $20,228 on average. If no complications occurred, the mean cost within the first year was $79,222. These results provide cost estimates for complicated and uncomplicated HDCT procedures, as well as costs for management of specific transplant complications.

A novel rapid single nucleotide polymorphism (SNP)-based method for assessment of hematopoietic chimerism after allogeneic stem cell transplantation.

A major end point of nonmyeloablative hematopoietic stem cell transplantation is the attainment of either mixed chimerism or full donor hematopoiesis. Because the majority of human genetic disparity is generated by single nucleotide polymorphisms (SNPs), direct measurement of SNPs should provide a robust tool for the detection and quantitation of chimerism. Using pyrosequencing, a rapid quantitative sequencing technology, we developed a SNP-based assay for hematopoietic chimerism. Based on 14 SNPs with high allele frequencies, we were able to identify at least 1 informative SNP locus in 55 patients with HLA-identical donors. The median number of informative SNPs in related pairs was 5 and in unrelated pairs was 8 (P <.0001). Assessment of hematopoietic chimerism in posttransplantation DNA was shown to be quantitative, accurate, and highly reproducible. The presence of 5% donor cells was reliably detected in replicate assays. Compared with current measures of engraftment based on identification of short tandem repeats (STRs), variable number of tandem repeats (VNTRs), or microsatellite polymorphisms, this SNP-based method provides a more rapid and quantitative assessment of chimerism. A large panel of SNPs enhances the ability to identify an informative marker in almost all patient/donor pairs and also facilitates the simultaneous use of multiple markers to improve the statistical validity of chimerism measurements. The inclusion of SNPs that encode minor histocompatibility antigens or other genetic polymorphisms that may influence graft-versus-host disease or other transplantation outcomes can provide additional clinically relevant data. SNP-based assessment of chimerism is a promising technique that will assist in the analysis of outcomes following transplantation.

Comparison of T-cell-depleted and non-T-cell-depleted unrelated donor transplantation for hematologic diseases: clinical outcomes, quality of life, and costs.

T-cell depletion (TCD) and immunosuppressive medications (ISTs) are 2 methods used for graft-versus-host disease (GVHD) prophylaxis in unrelated donor (URD) transplantation. However, comparisons of the clinical outcomes including quality of life and direct medical costs associated with each type of procedure have not been reported. We reviewed 48 TCD and 98 IST procedures performed from 1/1/97 to 12/31/99 at the Dana-Farber Cancer Institute, Boston, MA. With a median follow-up of 1.5 years for survivors, no differences were seen in relapse, acute GVHD, and overall survival between TCD and IST patients. Multivariable Cox modeling showed that age of 50 years or less (P =.002) and low-risk disease (P =.001) predicted survival, but method of GVHD prophylaxis (P =.6) and degree of human leukocyte antigen (HLA) matching (P =.8) did not. A subset of patients (53%) completed quality of life surveys prior to and at 6 and 12 months after transplantation; participation in the quality of life study was not associated with clinical characteristics and outcomes. No differences were seen in quality of life scores prior to transplantation, and changes over time were similar between groups. Costs ($113 000 vs $155 000, P <.0001) and total hospital days (34 vs 46, P =.0006) were significantly lower for patients undergoing TCD procedures. As prospective, randomized studies comparing methods of GVHD prophylaxis are performed, assessment of quality of life and costs should be included to fully understand the overall impact of each intervention.
