Association of Patient-Reported Physical Activity on Allogeneic Hematopoietic Cell Transplant Outcomes.
Ontology highlight
ABSTRACT: Background
Physical function prior to allogeneic hematopoietic cell transplant (HCT) is associated with survival and may be associated with patient physical activity (PA). Tools to evaluate PA prior to HCT are scarce. We aimed to evaluate the impact of easily obtained patient-report of PA prior to HCT on survival.Methods
HCT recipients between January 1, 2011 and July 5, 2018 and who completed an International Physical Activity Questionnaire Short Form were included. This patient survey captures self-reported activities over the preceding week to determine PA level.Results
We report a retrospective study of 587 adult (age ≥18) HCT recipients. The median age for the cohort was 57.9 years (range 19.9-76.1) with 149 patients (25.4%) age ≥65. Younger patients reported higher PA (low, median age 59.7 years; moderate, 56.1; high, 55.7; p < 0.001). High activity level was reported by males (66.7%; p < 0.001). Patients with low PA had HCT-comorbidity index (HCT-CI) ≥ 3 (68.1%, p = 0.002). When controlling for HCT-CI and disease risk index, higher PA was associated with improved overall survival (HR 0.954, 95% CI 0.921-0.988, p = 0.009). After adjusting for HCT-CI, higher PA was associated with reduced non-relapse mortality (NRM) (HR 0.931, 95% CI 0.891-0.972, p = 0.0013). Subgroup analysis in adults age ≥65 years also found that PA was lower in this population and associated with NRM mortality (HR 0.95, 95% CI 0.90-0.99, p = 0.041).Conclusion
Patient-reported PA is a predictor of post-HCT survival. Future studies to validate incorporation of self-report tools to better predict patient-related adverse risk are warranted.

Project description:There are limited data on patient experience after chimeric antigen receptor (CAR) T-cell therapy, especially in comparison to autologous and allogeneic transplantation, which are more established forms of cellular therapy. We prospectively evaluated longitudinal patient-reported quality of life (QoL), symptom burden and cognition after CAR-T cell therapy and compared it with prospective cohorts of patients undergoing autologous stem cell transplantation (autoSCT) and allogeneic SCT (alloSCT). This was a single center study. The primary endpoint was change in QoL. Secondary endpoints were patient-reported adverse events (PRO-AEs) measured by Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) and cognitive function (NeuroQOLv2 questionnaire). Time profile of PRO-AEs was evaluated using longitudinal analysis, Toxicity over Time (ToxT). Patients completed questionnaires at baseline, week 2 and monthly for 6 months. One hundred four patients were evaluable (CAR-T: 34, autoSCT: 33, alloSCT: 37). Baseline QoL was similar across groups. We observed a short-term decline in QoL in all groups that gradually returned to baseline. The nadir in QoL was at week 2 and coincided with peak in symptom burden. The decline in overall QoL, physical and functional well-being was significantly less with CAR-T versus SCT groups and returned to baseline faster. Patients in the alloSCT group experienced the greatest symptom burden, greater decrease in performance status, largest short-term decline in QoL and slowest recovery. This study provides comprehensive data comparing QoL, PRO-AEs and cognition following CAR-T cell therapy versus autoSCT and alloSCT, and the first application of ToxT to PRO-CTCAE data. Short-term QOL, including physical and functional domains was better in the CAR-T group versus SCT groups, although all groups experienced an initial decline coinciding with peak symptoms. These data can serve as a guide for patient education, symptom management, and future studies in CAR-T cell therapy.

Project description:Patient-reported outcomes among survivors of pediatric hematopoietic stem cell transplant (HSCT) are understudied. We compared symptom prevalence, health-related quality of life (HRQOL), and risk factors in adult survivors of childhood hematologic malignancies treated with HSCT to those treated with conventional therapy and noncancer controls. Survivors of childhood hematologic malignancies (HSCT N = 112 [70% allogeneic, 30% autologous]; conventionally treated N = 1106) and noncancer controls (N = 242) from the St. Jude Lifetime Cohort Study completed surveys assessing 10 symptom domains and SF-36 HRQOL summary scores. Chronic health conditions (CHCs) were validated by clinical assessment. Multivariable logistic regression reveals that compared with noncancer controls, HSCT survivors endorsed a significantly higher symptom prevalence in sensation (OR = 4.7, 95% confidence interval [CI], 2.6-8.4), motor/movement (OR = 4.3, 95% CI, 1.6-11.0), pulmonary (OR = 4.6, 95% CI, 1.8-11.8), and memory domains (OR = 4.8, 95% CI, 2.5-9.2), and poorer physical HRQOL (OR = 6.9, 95% CI, 2.8-17.0). HSCT and conventionally treated survivors had a similar prevalence of all symptom domains and HRQOL (all P > .05); however, HSCT survivors had a significantly higher cumulative prevalence for specific symptoms: double vision (P = .04), very dry eyes (P < .0001), and trouble seeing when wearing glasses (P < .0001). Occurrence of organ-specific CHCs, instead of transplant receipt, was significantly associated with a higher prevalence of all symptom domains (all P < .05) in adult survivors of childhood cancer, except for pain and anxiety domains. This study found that patient-reported outcomes were equally impaired between HSCT and conventionally treated survivors, but poorer in both groups compared with noncancer controls. Poor patient-reported outcomes in all survivors of childhood hematologic malignancies correlated with the presence of CHCs, whether treated with conventional therapy or HSCT.

Project description:Post bone marrow transplant patients are susceptible to atypical infections, especially viral pathogens. The risk increases many folds in cases of allogeneic transplantation, which also receive GVHD prophylaxis. Viral pathogens like cytomegalovirus and herpes are the common ones encountered during follow-up period. However, in recent times there have been reports of a variety of disease manifestations of rare viruses like polyoma virus and adenovirus. These viral infections may play a crucial role in morbidity and mortality in immunocompromised patients. We hereby elaborate the follow-up course of a 36-year-old post allogeneic transplant patient of acute myeloid leukemia who developed adenovirus related haemorrhagic cystitis. Treatment with oral ribavirin lead to dramatic improvement in symptomatology within a week. This cases re-emphasizes the fact that after ruling out the commoner pathogens, it's of utmost importance to strongly consider the atypical pathogens in such cases.

Project description:We conducted a prospective study of adult allogeneic hematopoietic cell transplantation (HCT) recipients to assess pre- and post-HCT physical function. Baseline measurements included a wrist actigraphy, a 6 min walk test (6MWT), an international physical activity questionnaire (IPAQ), and a Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) as well as serial post-HCT assessments of 6MWT, IPAQ, and FACT-BMT. Forty-seven patients were evaluable for functionality assessments, with a median follow-up of 54.5 months for surviving recipients. No patients demonstrated vigorous or very vigorous activity at any time during monitoring by wrist actigraphy; patients spent a median of 6 h daily sedentary. Self-reported activity via the IPAQ showed 36%, 43%, and 21% of subjects reporting light, moderate, and vigorous activity prior to HCT, respectively. Post-HCT 6MWTs on day +30 demonstrated the greatest association with subsequent survival and non-relapse mortality. A decline in 6MWT distance over time also demonstrated worsened overall survival. This study shows the feasibility of fitness assessments and the ability to risk stratify for subsequent mortality, particularly using the 6MWT on the day +30 single time point assessment and change scores from baseline to day +30 post HCT. These pilot findings suggest important targets for future study.

Project description:Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in early cerebral adrenoleukodystrophy can stabilize neurologic function and improve survival but has associated risks including transplant-related mortality (TRM), graft failure, and graft-versus-host disease (GVHD). An observational study of 59 patients with median age at allo-HSCT of 8 years addressed impact of donor source, donor match, conditioning regimen, and cerebral disease stage on first allo-HSCT outcomes. Efficacy analyses included 53 patients stratified by disease category: advanced disease (AD; n = 16) with Loes score >9 or neurological function score (NFS) >1 and 2 early disease (ED) cohorts (ED1 [Loes ≤4 and NFS ≤1; n = 24] and ED2 [Loes >4-9 and NFS ≤1; n = 13]). Survival free of major functional disabilities and without second allo-HSCT at 4 years was significantly higher in the ED (66%) vs AD (41%) cohort (P = .015) and comparable between ED1 and ED2 cohorts (P = .991). The stabilization of neurologic function posttransplant was greater in the ED vs AD cohort, with a median change from baseline at 24 months after allo-HSCT in NFS and Loes score, respectively, of 0 and 0.5 in ED1 (n = 13), 0.5 and 0 in ED2 (n = 6), and 2.5 and 3.0 (n = 4) in AD cohort. TRM was lower in the ED (7%) compared with the AD (22%) cohort; however, the difference was not significant (P = .094). Transplant-related safety outcomes were also affected by transplant-related characteristics: graft failure incidence was significantly higher with unrelated umbilical cord grafts vs matched related donors (P = .039), and acute GVHD and graft failure incidences varied by conditioning regimen. This study was registered at www://clinicaltrials.gov as #NCT02204904.

Project description:There is increasing recognition that pathogenic germ line variants drive the development of hematopoietic cancers in many individuals. Currently, patients with hereditary hematologic malignancies (HHMs) receive similar standard therapies and hematopoietic stem cell transplant (HSCT) approaches as those with sporadic disease. We hypothesize that patients with myeloid malignancies and deleterious germ line predisposition variants have different posttransplant outcomes than those without such alleles. We studied 472 patients with myeloid neoplasms, of whom 26% had deleterious germ line variants and 34% underwent HSCT. Deleterious germ line variants in CHEK2 and DDX41 were most commonly seen in American and Australian cohorts, respectively. Patients with deleterious germ line DDX41 variants had a higher incidence of severe (stage 3-4) acute graft-versus-host disease (GVHD) (38%) than recipients with deleterious CHEK2 variants (0%), other HHM variants (12%), or patients without such germ line variants (9%) (P = .002). Importantly, the use of posttransplant cyclophosphamide reduced the risk of severe acute GVHD in patients receiving HSCT for deleterious germ line DDX41-associated myeloid neoplasms (0% vs 53%, P = .03). Based on these results, we advocate the use of posttransplant cyclophosphamide when individuals with deleterious germ line DDX41 variants undergo allogeneic HSCT for myeloid malignancies, even when transplantation has been performed using wild-type donors.

Project description:BackgroundThe management of respiratory virus infections prior to hematopoietic cell transplant (HCT) is difficult. We examined whether respiratory virus detection before HCT influenced the requirement for bronchoscopy, hospitalization, and overall survival following HCT.MethodsPre-HCT and weekly post-HCT nasal washes were collected through day 100 from patients with and without symptoms. Samples were tested by multiplex polymerase chain reaction for respiratory syncytial virus, parainfluenza viruses 1-4, influenza A and B, human metapneumovirus, adenovirus, and human rhinoviruses, coronaviruses, and bocavirus.ResultsOf 458 patients, 116 (25%) had respiratory viruses detected pre-HCT. Overall, patients with viruses detected pre-HCT had fewer days alive and out of the hospital and lower survival at day 100 (adjusted hazard ratio [aHR], 2.4; 95% confidence interval [CI], 1.3-4.5; P = .007) than patients with negative samples; this risk was also present with rhinovirus alone (aHR for mortality, 2.6; 95% CI, 1.2-5.5; P = .01). No difference in bronchoscopy incidence was seen in patients with and without respiratory viruses (aHR, 1.3; 95% CI, .8-2.0; P = .32). In symptomatic patients, those with respiratory viruses detected had increased overall mortality compared with patients without viruses detected (unadjusted HR, 3.5; 95% CI, 1.0-12.1; P = .05); among asymptomatic patients, detection of respiratory viruses was not associated with increased mortality.ConclusionsThese data support routine testing for respiratory viruses among symptomatic patients before HCT, and delay of transplant with virus detection when feasible, even for detection of rhinovirus alone. Further study is needed to address whether asymptomatic patients should undergo screening for respiratory virus detection before HCT.

Project description:Although hematopoietic cell transplantation (HCT) is the only curative therapy for many advanced hematologic cancers, little is known about the financial hardship experienced by HCT patients nor the association of hardship with patient-reported outcomes. We mailed a 43-item survey to adult patients approximately 180 days after their first autologous or allogeneic HCT at 3 high-volume centers. We assessed decreases in household income; difficulty with HCT-related costs, such as need to relocate or travel; and 2 types of hardship: hardship_1 (reporting 1 or 2 of the following: dissatisfaction with present finances, difficulty meeting monthly bill payments, or not having enough money at the end of the month) and "hardship_2" (reporting all 3). Patient-reported stress was measured with the Perceived Stress Scale-4, and 7-point scales were provided for perceptions of overall quality of life (QOL) and health. In total, 325 of 499 surveys (65.1%) were received. The median days since HCT was 173; 47% underwent an allogeneic HCT, 60% were male, 51% were > 60 years old, and 92% were white. Overall, 46% reported income decline after HCT, 56% reported hardship_1, and 15% reported hardship_2. In multivariable models controlling for income, those reporting difficulty paying for HCT-related costs were more likely to report financial hardship (odds ratio, 6.9; 95% confidence interval, 3.8 to 12.3). Hardship_1 was associated with QOL below the median (odds ratio, 2.9; 95% confidence interval, 1.7 to 4.9), health status below the median (odds ratio, 2.2; 95% confidence interval, 1.3 to 3.6), and stress above the median (odds ratio, 2.1; 95% confidence interval, 1.3 to 3.5). In this sizable cohort of HCT patients, financial hardship was prevalent and associated with worse QOL and higher levels of perceived stress. Interventions to address patient financial hardship-especially those that ameliorate HCT-specific costs-are likely to improve patient-reported outcomes.

Project description:Iatrogenic menopause with consequent infertility is a major complication in reproductive-age women undergoing hematopoietic cell transplantation (HCT). Recent guidelines recommend a discussion of the possibility of infertility and the options for fertility preservation as part of informed consent before initiation of any cancer-directed therapy, including HCT. Women age 15 to 49 years at the time of allogeneic HCT, between the years 2001 and 2017, were identified from the Mayo Clinic Rochester institutional HCT database. One hundred seventy-seven women were eligible, of whom 49 (28%) were excluded due to documented postmenopausal state or prior hysterectomy. The median age of the cohort was 31 years (range, 15 to 49 years) with median gravidity and parity being G1P1 (range, G0 to G8, P0 to P6). Fifty-four (42%) women were nulligravid at the time of HCT. Eighty-two percent underwent myeloablative conditioning (MAC), whereas 18% underwent reduced-intensity conditioning (RIC). Only 34 women (27%) had documented fertility counseling within 72 hours of diagnosis, and a total of 61 (48%) received fertility counseling prior to HCT. Thirty-eight women (30%) were referred to a reproductive endocrinologist, of whom 13 (10%) underwent assisted reproductive technologies (ART; nine oocyte cryopreservation, four embryo cryopreservation). Of these, nine procedures yielded successful cryopreserved tissue (two completed at outside institutions). The median time to completion of the seven successful ART procedures at Mayo Clinic was 13 days (range, 9 to 15 days). The remainder of women referred to reproductive endocrinology did not undergo ART due to disease severity (68%), financial barriers (20%), and/or low antral follicle count (12%). Ninety-three women (73%) received leuprolide for ovarian suppression prior to conditioning. Three (4%) of 75 women who underwent MAC and were alive >365 days after HCT had spontaneous menstrual recovery after HCT (median time, 14 months; range, 6 to 21 months), in comparison to 10 (50%) of 20 women who underwent RIC and were alive >365 days after HCT (P < .01) (median, 21.5 months; range, 5 to 83 months). In the latter cohort, there were two spontaneous pregnancies, occurring at 71 and 72 months after HCT, respectively. Oncofertility is an emerging field due to an increasing number of young cancer survivors. Herein, we document that even at a large tertiary HCT center, the rate of documented fertility counseling and reproductive endocrinology referrals was low and the rate of ART was even lower. Spontaneous menstrual recovery was rare but more likely in the setting of nonmalignant disease and RIC HCT. A concerted multidisciplinary effort is needed to understand parenthood goals and to explore the impact of HCT on decision making about fertility preservation and parenthood. These efforts could improve oncofertility referral, ART utilization, and reproductive outcomes.

Project description:AbstractAllogeneic hematopoietic cell transplantation (HCT) can be complicated by life-threatening organ toxicity and infection necessitating intensive care. Epidemiologic data have been limited by single-center studies, poor database granularity, and a lack of long-term survivors. To identify contemporary trends in intensive care unit (ICU) use and long-term outcomes, we merged data from the Center for International Blood and Marrow Transplant Research and the Virtual Pediatric Systems databases. We identified 6995 pediatric patients with HCT aged ≤21 years who underwent first allogeneic HCT between 2008 and 2014 across 69 centers in the United States or Canada and followed patients until the year 2020. ICU admission was required for 1067 patients (8.3% by day +100, 12.8% by 1 year, and 15.3% by 5 years after HCT), and was linked to demographic background, pretransplant organ toxicity, allograft type and HLA-match, and the development of graft-versus-host disease or malignancy relapse. Survival to ICU discharge was 85.7%, but more than half of ICU survivors required ICU readmission, leading to 52.5% and 42.6% survival at 1- and 5-years post-ICU transfer, respectively. ICU survival was worse among patients with malignant disease, poor pretransplant organ function, and alloreactivity risk factors. Among 1-year HCT survivors, those who required ICU in the first year had 10% lower survival at 5 years and developed new dialysis-dependent renal failure at a greater rate (P<.001). Thus, although ICU management is common and survival to ICU discharge is high, ongoing complications necessitate recurrent ICU admission and lead to a poor 1-year outcome in select patients who are at high risk.
