Gray TF, Do KM, Amonoo HL, Sullivan L, Kelkar AH, Pirl WF, Hammer MJ, Tulsky JA, El-Jawahri A, Cutler CS, Partridge AH. Family Caregiver Experiences in the Inpatient and Outpatient Reduced-Intensity Conditioning Allogeneic Hematopoietic Cell Transplantation Settings: A Qualitative Study. Transplant Cell Ther 2024; 30:610.e1-610.e16. [PMID: 37783339 DOI: 10.1016/j.jtct.2023.09.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 09/21/2023] [Accepted: 09/24/2023] [Indexed: 10/04/2023]
Abstract
Caregivers (ie, family and friends) are essential in providing care and support for patients undergoing hematopoietic cell transplantation (HCT) and throughout their recovery. Traditionally delivered in the hospital, HCT is being increasingly provided in the outpatient setting, potentially heightening the burden on caregivers. Extensive work has examined the inpatient HCT caregiving experience, yet little is known about how caregiver experiences may differ based on whether the HCT was delivered on an inpatient or outpatient basis, particularly during the acute recovery period post-HCT. This study explored the similarities and differences in caregiver experiences in the inpatient and outpatient settings during the early recovery from reduced-intensity conditioning (RIC) allogeneic HCT. We conducted semistructured interviews (n = 15) with caregivers of adults undergoing RIC allogeneic HCT as either an inpatient (n = 7) or an outpatient (n = 8). We recruited caregivers using purposeful criterion sampling, based on the HCT setting, until thematic saturation occurred. Interview recordings were transcribed and coded through thematic analysis using Dedoose v.9.0. The study analysis was guided by the transactional model of stress and coping and the model of adaptation of family caregivers during the acute phase of BMT. Three themes emerged to describe similar experiences for HCT caregivers regardless of setting: (1) caregivers reported feeling like they were a necessary yet invisible part of the care team; (2) caregivers described learning to adapt to changing situations and varying patient needs; and (3) caregivers recounted how the uncertainty following HCT felt like existing between life and death while also maintaining a sense of gratitude and hope for the future. Caregivers also reported distinct experiences based on the transplantation setting and 4 themes emerged: (1) disrupted routines: inpatient caregivers reported disrupted routines when caring for the HCT recipient while simultaneously trying to manage non-caregiving responsibilities at home and work, and outpatient caregivers reported having to establish new routines that included frequent clinic visits with the patient while altering or pausing home and work responsibilities; (2) timing of caregiver involvement: inpatient caregivers felt more involved in care after the patient was discharged from the HCT hospitalization, whereas outpatient caregivers were already providing the majority of care earlier in the post-transplantation period; (3) fear of missing vital information: inpatient caregivers worried about missing vital information about the patient's care and progress if not physically present in the hospital, whereas outpatient caregivers feared overlooking vital information that may warrant contacting the care team as they monitored the patient at home; and (4) perceived adequacy of resources to meet psychosocial and practical needs: inpatient caregivers reported having adequate access to resources (ie, hospital-based services), whereas outpatient caregivers felt they had more limited access and needed to be resourceful in seeking out assistance. Inpatient and outpatient HCT caregivers described both similar and distinct experiences during the acute recovery period post-HCT. Specific interventions should address caregiver psychosocial needs (ie, distress, illness uncertainty, communication, and coping) and practical needs (ie, community resource referral, preparedness for home-based caregiving, and transplantation education) of HCT caregivers based on setting.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered for patients with high-risk B-cell lymphoma and relapsed or refractory disease. This study aimed to analyze the long-term follow-up data of patients who underwent allo-HSCT in Taiwan. This was a retrospective observational study using data from the Taiwan Society of Blood and Marrow Transplantation database. A total of 105 patients who underwent allo-HSCT because of high-risk, relapsed, or refractory disease between 2010 and 2019 were included. Forty-five percent of the patients previously underwent autologous stem cell transplantation (ASCT). The median follow-up duration was 18.6 months. The probability of 3-year progression-free survival and overall survival (OS) was 34.5% and 37%, respectively. The probability of 1-year non-relapse mortality was 31.4%, and the major cause was infection (75.8%). The multivariable analysis showed that not in remission at the time of transplantation and the absence of graft-versus-host disease (GVHD) were factors associated with inferior OS. The probability of 3-year OS in patients with diffuse large B-cell lymphoma who underwent allo-HSCT and allo-HSCT after ASCT was 40.2% and 25.2%, respectively. Allo-HSCT could be a salvage therapeutic option for relapsed or refractory B-cell lymphoma. Complete remission at the time of allo-HSCT and the presence of GVHD are independent variables for overall survival.

Abstract
While acknowledging that newer therapies have improved survival rates in chronic lymphocytic leukemia (CLL), patients with high-risk disease features are at an increased risk of treatment failure. Allogeneic hematopoietic cell transplantation (allo-HCT) was traditionally offered as front-line consolidation in high-risk CLL; however, with the emergence of targeted therapies like Bruton tyrosine kinase (BTK) and B-cell lymphoma 2 (BCL-2) inhibitors, the role of allo-HCT has been relegated to later stages of the disease. Patients with relapsed/refractory (R/R) CLL who have failed both BTK and BCL-2 inhibitors represent a therapeutic challenge owing to a poor prognosis. Chimeric antigen receptor T-cell (CAR T) therapies targeting CD19 have improved response rates and overall survival in various types of R/R B-cell non-Hodgkin lymphomas. For CLL, no approved CAR T-cell therapies are yet available. Emerging data appear to show a therapeutic benefit of CAR T-cell therapy in patients with R/R CLL, even after failing an allo-HCT.

Abstract
Although the use of allogeneic hematopoietic cell transplantation (HCT) for chronic lymphocytic leukemia (CLL) has declined with the development of novel targeted agents, it continues to play an important role for eligible patients with high-risk or heavily pretreated CLL who lack other treatment options. CLL is susceptible to a potent graft-versus-leukemia (GVL) effect which produces long-lasting remissions in 30-50% of transplanted patients. While allogeneic HCT is associated with significant risks of graft-versus-host disease (GVHD), infection, and non-relapse mortality (NRM), improvements in patient and donor selection, reduced intensity conditioning (RIC), GVHD prophylaxis, and supportive care have rendered this an increasingly safe and effective procedure in the current era. In this review, we discuss recent advances in allogeneic HCT for CLL, with a focus on the optimal evidence-based strategies to maximize benefit and minimize toxicity of this potentially curative cellular therapy.

Abstract
Lisocabtagene maraleucel (liso-cel) is an autologous CD19-directed chimeric antigen receptor (CAR) T cell product, with a CD3ζ activatory domain connected to 4-1BB costimulatory domain. Liso-cel, unlike the other two approved products-axicabtagene ciloleucel and tisagenlecleucel-is manufactured separately from CD4 and CD8 T cells and then administered as a sequential infusion of the two components at equal target doses. The approval of liso-cel was based on the results of Transcend NHL 001, a single-arm, open-label, multicenter, seamless design trial that enrolled 344 patients, of whom 269 received conforming liso-cel. The most common histology was diffuse large B cell lymphoma, not otherwise specified (DLBCL NOS; n = 137, 51%) followed by DLBCL transformed from indolent lymphomas (n = 78, 29%). Encouraging results were reported, yielding an objective response rate across all dose levels of 73% [complete remission (CR) = 53%], with an estimated duration of response at 1 year of 55% for all patients and 65% for those achieving a CR. The estimated 12-month overall survival was 58% for all patients and 86% for those achieving a CR. Cytokine release syndrome and neurological adverse events were reported in 42% and 30%, respectively. This review summarizes the evidence on the safety and effectiveness of liso-cel, resulting in its addition to the current treatment armamentarium of relapsed or refractory large B cell lymphoma.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation (allo-HCT) is currently the only curative treatment for patients with chronic lymphocytic leukemia (CLL). METHODS We analyzed the outcomes of 93 patients (median age: 52 years) who underwent allo-HCT at our center between 1989 and 2019. RESULTS After a median follow-up of 35 months, relapse was observed in 15.1% (n = 14) patients. The estimated 2-year non-relapse mortality, relapse-free survival, and overall survival (OS) were 38.1%, 54.2%, and 58.7%, respectively. The ECOG performance status ≥ 2 (hazard ratio [HR]: 4.1; p = .001) and use of total body irradiation (in a myeloablative conditioning regimen; HR: 2.64; p = .005) were predictive of poor OS after multivariable analysis. The occurrence of sinusoidal obstruction syndrome/veno-occlusive disease post-transplant was associated with poor survival (p = .001). CONCLUSION Although the use of kinase and bcl2 inhibitors may result in a decrease in the number and need of transplants, allo-HCT remains a viable option in selected patients with high-risk CLL and good performance status.

Abstract
Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the Western hemisphere. The recent availability of novel targeted therapies, namely Bruton's tyrosine kinase, phosphoinositide-3 kinase, and BCL-2 inhibitors, have revolutionized the treatment algorithm for CLL but have not yet resulted in cure. Advances in the field of immuno-oncology and T cell engineering brought chimeric antigen receptor (CAR) T cell therapy from the laboratory to the clinic for treatment of B cell lymphoid malignancies and has improved the disease response and survival outcomes of various types of relapsed and/or refractory B cell lymphomas. While acknowledging that there are no approved CAR T cell therapies for CLL at this time, in this comprehensive review we explore novel targets for CAR T cell therapy in CLL and highlight the promising results of CAR T cell trials reported to date. Furthermore, we shed light on future areas of development, including multitarget CAR T cell products for this disease.

Abstract
Richter syndrome (RS) represents a transformation from chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) to aggressive lymphoma, most commonly diffuse large B-cell lymphoma (DLBCL), which is associated with a dismal prognosis. Patients with DLBCL-RS have poor outcomes with DLBCL-directed therapy; thus, consolidation with hematopoietic cell transplantation (HCT) has been used, with durable remissions observed. Studies reporting HCT outcomes in patients with DLBCL-RS have been small, have not evaluated the prognostic impact of cytogenetic risk factors, and were conducted prior to the era of novel targeted therapy of CLL/SLL. We performed a Center for International Blood and Transplant Research registry study evaluating outcomes after autologous HCT (auto-HCT; n = 53) and allogeneic HCT (allo-HCT; n = 118) in patients with DLBCL-RS treated in the modern era. More auto-HCT recipients were in complete response (CR) at HCT relative to allo-HCT recipients (66% vs 34%), whereas a higher proportion of allo-HCT recipients had 17p deletion (33% vs 7%) and had previously received novel agents (39% vs 10%). In the auto-HCT cohort, the 3-year relapse incidence, progression-free survival (PFS), and overall survival (OS) were 37%, 48%, and 57%, respectively. Among allo-HCT recipients, the 3-year relapse incidence, PFS, and OS were 30%, 43%, and 52%, respectively. In the allo-HCT cohort, deeper response at HCT was associated with outcomes (3-year PFS/OS, 66%/77% CR vs 43%/57% partial response vs 5%/15% resistant; P < .0001 for both), whereas cytogenetic abnormalities and prior novel therapy did not impact outcomes. In our study, HCT resulted in durable remissions in therapy-sensitive patients with DLBCL-RS treated in the era of targeted CLL/SLL therapy, including patients with high-risk features.

Abstract
Background The economics of allogeneic hematopoietic cell transplantation (alloHCT) for older patients with acute myeloid leukemia (AML) affects clinical practice and public policy. To assess reimbursement, utilization, and overall survival (OS) up to 1 year post-alloHCT for Medicare beneficiaries aged 65 years or older with AML, a unique merged dataset of Medicare claims and national alloHCT registry data was analyzed. Methods Patients diagnosed with AML undergoing alloHCT from 2010 to 2011 were included for a retrospective cohort analysis with generalized linear model adjustment. One-year post-alloHCT reimbursement included Medicare, secondary payer, and beneficiary copayments (no coinsurance) (inflation adjusted to 2017 dollars). Cost-to-charge ratios were applied to estimate department-specific inpatient costs. Cox proportional hazards regression models were utilized to identify risk factors of 1-year OS post-alloHCT. Results A total of 250 patients met inclusion criteria. Mean total reimbursement was $230 815 (95% confidence interval [CI] = $214 381 to $247 249) 1 year after alloHCT. Pharmacy was the most- costly inpatient service category. Adjusted mean total reimbursement was statistically higher for patients who received cord blood grafts (P = .01), myeloablative conditioning (P < .0001), and alloHCT in the Northeast and West (P = .03). Mortality increased with age (hazard ratio [HR] = 1.08, 95% CI = 1.0 to 1.17), poorer Karnofsky performance score (<90% vs ≥90%, HR = 1.60, 95% CI = 1.08 to 2.35), and receipt of myeloablative conditioning (HR = 1.88, 95% CI = 1.21 to 2.92). Conclusions This merged dataset allowed adjustment for a richer set of patient- and HCT-related characteristics than claims data alone. The finding that nonmyeloablative conditioning was associated with lower reimbursement and improved OS 1 year post-alloHCT warrants further investigation.

Abstract
In the pathway inhibitor era, the number of allogeneic stem cell transplantation (ASCT) for chronic lymphocytic leukemia (CLL) continues to decrease and this approach should be offered only after careful risk-benefit assessment. Nevertheless, ASCT still remains only curative therapeutic modality for CLL, especially in countries with limited access to novel agents. Thirty patients with CLL at median age of 42 years at diagnosis (range 29-64) underwent ASCT between years 2002 and 2018. Thirteen patients were transplanted in complete remission (CR), ten patients achieved partial response (PR), and seven had stable disease. The median time from diagnosis to transplant was 4 years (range 0.5-12). Twenty-three patients received HLA-matched related donor stem cell grafts, and seven patients received either matched unrelated donor or HLA-mismatched grafts. Reduced intensity conditioning (RIC) and myeloablative regimen (MAC) were used in 24 and 6 patients, respectively. Mortality to day + 100 after transplant was 16% (8% for RIC only). Acute and chronic graft versus host disease (GVHD) developed in 40% and 63% of patients, respectively. Fifteen patients relapsed or progressed after transplant. Thirteen patients (43%) are alive at last follow-up and 10 (77%) remain in clinical CR. Median follow-up for survivors was 6.8 years (range 0.4-15.2). Three-year progression-free and overall survivals were 56% and 60%, respectively. These outcomes were better for patients who received RIC conditioning: 64% and 72%, respectively. CR at transplant was found to have favorable impact on post-allograft survival. RIC should be preferred over MAC. ASCT may remain a valuable option for some CLL patients.
