Hematopoietic stem cell transplantation for pediatric patients with non-anaplastic peripheral T-cell lymphoma. An EBMT pediatric diseases working party study

Peripheral T-cell lymphomas (PTCL) other than anaplastic large-cell lymphoma are rare in children, and the role of hematopoietic stem cell transplantation (HSCT) has not been clarified yet. In a retrospective analysis of registry-data of the European Society for Blood and Marrow Transplantation we analyzed 55 patients aged < 18 years who received allogeneic (N = 46) or autologous (N = 9) HSCT for PTCL. Median age at HSCT was 13.9 years; 33 patients (60%) were in first remission, and 6 (19%) in progression at HSCT. Conditioning was myeloablative in 87% of the allogeneic HSCTs and in 27 (58.7%) based on total body irradiation. After allogeneic HSCT the 5-year overall- and progression-free survival was 58.9% (95% CI 42.7–71.9) and 52.6% (95% CI 36.8–66.1), respectively. 5-year relapse incidence was 27.6% (95% CI 15.1–41.6), the non-relapse mortality rate was 19.8% (95% CI 9.7–32.6). Five of the six patients with progression at HSCT died. Seven of nine patients after autologous HSCT were alive and disease-free at last follow-up. Our data suggest a role of allogeneic HSCT in consolidation-treatment of patients with high-risk disease, who reach at least partial remission after primary- or relapse-therapy, whereas patients with therapy-refractory or progressive disease prior to transplantation do not profit from HSCT.

Experiences of being treated with autologous haematopoietic stem cell transplantation for aggressive multiple sclerosis: A qualitative interview study.

Autologous haematopoietic stem cell transplantation (AHSCT) is increasingly used as a treatment for aggressive multiple sclerosis (MS) and has the potential to induce long-term remission and resolution of disease activity. Despite the extensive research on treatment outcome after AHSCT, the experience of living with MS after AHSCT has not been previously described in the scientific literature. The aim of this study was to explore long-term lived experience of people with MS treated with AHSCT. To exclude selection bias, all persons treated with AHSCT for MS at Uppsala University Hospital, Sweden, between 2004 and 2007 (n = 10), were asked to participate in the study, and all accepted. Open-ended interviews were conducted, digitally recorded, transcribed verbatim, and then subjected to qualitative content analysis with an inductive approach. Five main themes emerged from the interviews: (I) being diagnosed with MS-an unpredictable existence; (II) a new treatment-a possibility for a new life; (III) AHSCT-a transition; (IV) reclaiming life; and (V) a bright future accompanied by insecurity. AHSCT was described by the participants in terms of a second chance and an opportunity for a new life. The treatment became a transition from a state of illness to a state of health, enabling a previous profound uncertainty to wane and normality to be restored. Although participants of different age and sex were included, the main limitation of this study is the relatively small number of participants. Also, the inclusion of persons from one centre alone could restrict transferability of the results. The results give a first insight into lived experience following a highly effective induction treatment for MS, and the experience of not having MS anymore. Underpinned by previously described outcome following AHSCT, the results of this study challenge the current view on MS as a chronic disease with no possible cure.

FDA Approval Summary: Lisocabtagene Maraleucel for Second-Line Treatment of Large B-Cell Lymphoma.

In June 2022, the FDA extended the indication for lisocabtagene maraleucel (liso-cel) to include adults with large B-cell lymphoma (LBCL) who have refractory disease or relapse within 12 months of first-line chemoimmunotherapy (CIT), as well as transplant-ineligible adults with refractory disease or relapse after first-line CIT. Two clinical trials evaluating a single infusion of liso-cel preceded by lymphodepleting chemotherapy supported the second-line indications. TRANSFORM is a randomized, phase 3, open-label trial comparing liso-cel with standard second-line therapy, including planned autologous hematopoietic stem cell transplantation (HSCT), in 184 transplant-eligible patients. On interim analysis, event-free survival (EFS) by independent review committee (IRC) assessment was statistically significantly improved for the liso-cel arm, with a stratified hazard ratio of 0.34 [95% confidence interval (CI), 0.22-0.51; P < 0.0001]; the estimated median EFS was 10.1 months in the liso-cel arm versus 2.3 months in the control arm. PILOT is a single-arm phase 2 trial of second-line liso-cel in patients who were transplant-ineligible due to age or comorbidities but had adequate organ function for chimeric antigen receptor (CAR) T-cell therapy. Among 61 patients who received liso-cel (median age, 74 years), the IRC-assessed complete response rate was 54% (95% CI, 41-67). Among patients achieving complete response, the estimated 1-year rate of continued response was 68% (95% CI, 45-83). Of the 268 patients combined who received liso-cel as second-line therapy for LBCL, cytokine release syndrome occurred in 45% (Grade 3, 1.3%) and CAR T-cell-associated neurologic toxicities occurred in 27% (Grade 3, 7%), warranting a continued risk evaluation and mitigation strategy.

Safety and efficacy of autologous haematopoietic stem-cell transplantation with low-dose cyclophosphamide mobilisation and reduced intensity conditioning versus standard of care in refractory Crohn's disease (ASTIClite): an open-label, multicentre, randomised controlled trial

A previous controlled trial of autologous haematopoietic stem-cell transplantation (HSCT) in patients with refractory Crohn's disease did not meet its primary endpoint and reported high toxicity. We aimed to assess the safety and efficacy of HSCT with an immune-ablative regimen of reduced intensity versus standard of care in this patient population. This open-label, multicentre, randomised controlled trial was conducted in nine National Health Service hospital trusts across the UK. Adults (aged 18-60 years) with active Crohn's disease on endoscopy (Simplified Endoscopic Score for Crohn's Disease [SES-CD] ulcer sub-score of ≥2) refractory to two or more classes of biological therapy, with no perianal or intra-abdominal sepsis or clinically significant comorbidity, were recruited. Participants were centrally randomly assigned (2:1) to either HSCT with a reduced dose of cyclophosphamide (intervention group) or standard care (control group). Randomisation was stratified by trial site by use of random permuted blocks of size 3 and 6. Patients in the intervention group underwent stem-cell mobilisation (cyclophosphamide 1 g/m2 with granulocyte colony-stimulating factor (G-CSF) 5 μg/kg) and stem-cell harvest (minimum 2·0 × 106 CD34+ cells per kg), before conditioning (fludarabine 125 mg/m2, cyclophosphamide 120 mg/kg, and rabbit anti-thymocyte globulin [thymoglobulin] 7·5 mg/kg in total) and subsequent stem-cell reinfusion supported by G-CSF. Patients in the control group continued any available conventional, biological, or nutritional therapy. The primary outcome was absence of endoscopic ulceration (SES-CD ulcer sub-score of 0) without surgery or death at week 48, analysed in the intention-to-treat population by central reading. This trial is registered with the ISRCTN registry, 17160440. Between Oct 18, 2018, and Nov 8, 2019, 49 patients were screened for eligibility, of whom 23 (47%) were randomly assigned: 13 (57%) to the intervention group and ten (43%) to the control group. In the intervention group, ten (77%) participants underwent HSCT and nine (69%) reached 48-week follow-up; in the control group, nine (90%) reached 48-week follow-up. The trial was halted in response to nine reported suspected unexpected serious adverse reactions in six (46%) patients in the intervention group, including renal failure due to proven thrombotic microangiopathy in three participants and one death due to pulmonary veno-occlusive disease. At week 48, absence of endoscopic ulceration without surgery or death was reported in three (43%) of seven participants in the intervention group and in none of six participants in the control group with available data. Serious adverse events were more frequent in the intervention group (38 in 13 [100%] patients) than in the control group (16 in four [40%] patients). A second patient in the intervention group died after week 48 of respiratory and renal failure. Although HSCT with an immune-ablative regimen of reduced intensity decreased endoscopic disease activity, significant adverse events deem this regimen unsuitable for future clinical use in patients with refractory Crohn's disease.

(328) The Relationship Between Multiple Myeloma and Hypogonadism: A Systematic Review

Abstract Introduction Hypogonadism has been reported with substantial frequency in patients with various types of malignancies. Multiple myeloma (MM) is a cancer that affects plasma cells, a type of white blood cell responsible for producing antibodies. It is the second most common blood cancer, accounting for approximately 10% of hematologic malignancies. However, the prevalence, pathophysiology, and significance of hypogonadism as a sequela of MM or its standardized treatment regimens has not been extensively studied. Objective To characterize the existing literature on hypogonadism in patients with MM, including the prevalence, underlying mechanisms, and link to overall disease prognosis. Furthermore, we will examine the effects of testosterone therapy on MM and its hypogonadal symptomatology. Methods Relevant studies published up to November 2022 were retrieved through a search of PubMed using the keywords ‘hypogonadism’, ‘multiple myeloma’, and ‘testosterone’. Studies that reported on the presentation, management, or outcomes of patients with MM and how they were affected by a hypogonadal state were included. The search yielded 72 studies, of which 11 met the inclusion criteria. Results The most comprehensive assessment of the frequency of hypogonadism in a MM cohort found that 74% of 561 MM patients were classified as hypogonadal compared to 33% of patients in a control population. Further evaluation found that male patients with MM were found to have significantly lower levels of testosterone than control (p&amp;lt;0.0001). Another assessment of hormone level differences between MM patients and controls found that male patients had higher: FSH, LH, estrogen, and E/T ratios than healthy controls. Testosterone supplementation was found to lower interleukin-6 (IL-6) levels, which could potentially contribute to the adverse effects of MM. This effect could arise from the finding that IL-6 concentration was independently associated with severe symptomatology in MM patients on multivariate analysis in a study by Wang et al. (p=0.004). Hypogonadism can occur as an adverse effect of MM treatment with immunotherapy/chemotherapy initiation. A small study by Greenfield et al. found that 65% of patients intensively treated for MM were subsequently hypogonadal. This was further supported by a study by Anderson et al. examining sexual function after autologous hematopoietic stem cell transplant (AHSCT), which saw a significant increase in erectile dysfunction at 1-month follow-up from 68.4% to 100% of all patients. Conclusions There appears to be a relationship between MM and hypogonadism, potentially due to the inflammatory state caused by the disease itself. This may have some association with the inflammatory cytokine IL-6. However, there is a paucity of data fully exploring this relationship, the underlying mechanisms, and the effects of testosterone therapy on MM. The true relationship is likely multifactorial, given the mixture of studies that found hypogonadism in MM at baseline as well as after systemic treatment. Future prospective and randomized studies are necessary to elucidate the true link between MM and/or its treatment and hypogonadism.

Evaluation of Total Parenteral Nutrition in the Autologous Transplantation Setting in Patients with AML: A Retrospective Exploratory Analysis

Malnutrition remains a clinical challenge in AML patients undergoing autologous hematopoietic stem cell transplantation (ASCT), leading to physical deconditioning and prolonged hospitalization. Prospective data are mainly lacking to identify those patients who may particularly benefit from parenteral nutrition in this setting. This observational, non-randomized, retrospective, exploratory cohort study assessed the nutritional development in patients following high-dose chemotherapy (HDCT) with ASCT and explored their survival outcomes. The study included all consecutive AML patients who underwent HDCT with ASCT at a single academic center between January 2000 and January 2019. Patients were divided into two primary cohorts: those who received TPN following high-dose chemotherapy and ASCT and those who did not. We identified 126 patients with AML in first complete remission undergoing ASCT consolidation, including 75 patients receiving TPN after HDCT and ASCT and 51 patients without TPN. Neither group differed in gender, age, or subgroups of AML. The nutritional condition at first diagnosis and after induction chemotherapy was equal in both groups, as were median weight changes throughout the induction chemotherapy cycles. Finally, progression-free and overall survival rates were comparable in both groups. Our data suggest that the need to provide TPN for an average of 11 days following HDCT with ASCT for consolidation of first remission in AML patients does not affect the clinical outcome of these patients.

Cerebrospinal fluid mtDNA concentrations are increased in multiple sclerosis and were normalized after intervention with autologous hematopoietic stem cell transplantation

BackgroundMitochondrial DNA (mtDNA) is a pro-inflammatory damage-associated molecular pattern molecule and could be an early indicator for inflammation and disease activity in MS. Autologous hematopoietic stem cell transplantation (aHSCT) is a potent treatment for MS, but its impact on mtDNA levels in cerebrospinal fluid (CSF) remains unexplored. ObjectivesTo verify elevated CSF mtDNA concentrations in MS patients and assess the impact of aHSCT on mtDNA concentrations. MethodsMultiplex droplet digital PCR (ddPCR) was used to quantify mtDNA and nuclear DNA in 182 CSF samples. These samples were collected from 48 MS patients, both pre- and post-aHSCT, over annual follow-ups, and from 32 healthy controls. ResultsCSF ccf-mtDNA levels were higher in patients with MS, correlated to multiple clinical and analytical factors and were normalized after intervention with aHSCT. Differences before aHSCT were observed with regard to MRI-lesions, prior treatment and number of relapses in the last year prior to aHSCT. ConclusionOur findings demonstrate elevated CSF mtDNA levels in MS patients, which correlate with disease activity and normalize following aHSCT. These results position mtDNA as a potential biomarker for monitoring inflammatory activity and response to treatment in MS.

Significance of IgH Gene Rearrangement in Surveillance of Minimal Residual Disease after Autologous Hematopoietic Stem Cell Transplantation in Multiple Myeloma

To investigate the value of immunoglobulin heavy chain (IgH) gene rearrangement in monitoring minimal residual disease (MRD) in multiple myeloma (MM) received autologous hematopoietic stem cell transplantation(auto-HSCT). The clinical data of 26 MM patients who received auto-HSCT in the Department of Hematology, Wuhan First Hospital from 2018 to 2022 were collected. IgH rearrangement was detected by multiplex PCR combined with capillary electrophoresis fragment analysis to evaluate minimal residual disease (MRD), and the outcome of the disease was analyzed statistically. Among the 26 MM patients, 18 were males and 8 were females, with a median age of 59(41-70) years. The median follow-up time after transplantation was 33 (7-52) months. Compared with the IgH rearrangement negative group (n=17), the proportion of CR and sCR of patients with IgH rearrangement positive in bone marrow samples before auto-HSCT at 3 months after transplantation was lower （1/9 vs 14/17）, and the duration of remission (DOR) after transplantation was shorter（10.78±4.35 vs 15.88±5.22 months）, with statistically significant difference in DOR between the two groups(P < 0.05). Compared with IgH rearrangement negative group (n=21), the proportion of CR and sCR of patients with positive IgH rearrangement results from peripheral blood stem cell collection at 3 months after transplantation was lower（0/5 vs 15/21）, the duration of remission (DOR) after transplantation was shorter（9.60±4.83 vs 15.19±5.11 months）, and the difference in DOR between the two groups was statistically significant (P < 0.05). During the follow-up period, 5 patients (5/9) with positive IgH rearrangement results in bone marrow specimens died, and all patients with negative IgH rearrangement results survived. Four patients (4/5) with positive IgH rearrangement results by peripheral blood stem cell samples died, while one patient (1/21) with negative IgH rearrangement results died. In both bone marrow and peripheral blood stem cell samples, the survival time of IgH rearrangement-positive patients after transplantation was shorter than that of IgH rearrangement-negative patients(P < 0.05). Logistic regression analysis showed that gender, disease stage, the proportion of bone marrow smear plasma cells at initial diagnosis, stem cell mobilization plan, efficacy evaluation before transplantation (≥CR and <CR), and CD34+ cell count had no effect on IgH rearrangement results of stem cell collection (P >0.05). By detecting IgH rearrangement of MM patients receiving auto-HSCT, the depth of MRD can be further evaluated, which has a certain guiding significance for the efficacy and prognosis of the disease.

Treatment Pattern and Outcome of Newly Diagnosed Multiple Myeloma Patients in a Resource-Limited Setting.

Multiple myeloma is the third most common hematologic malignancy in Malaysia. The introduction of novel agents over the past decades has improved patient outcome and survival substantially. However, these agents incur significant economic burden, thus leading to limited use in less developed countries. This study aims to report on the real-world treatment pattern and outcome of newly diagnosed multiple myeloma (NDMM) patients from a resource-constraint setting. This is a retrospective study on NDMM patients diagnosed between 1 January 2008 and 31 December 2022 in a single academic center. Patients' demographic and treatment details were included for analysis of progression free survival (PFS) and overall survival (OS). One hundred and thirty-six NDMM patients with a median age of 64.0 years (ranged from 38 to 87 years old) were included. Bortezomib-containing regimens were the most commonly used induction agent, followed by thalidomide. Almost half of the patients (47.1%) achieved very good partial response (VGPR) or complete remission (CR), while 31.6% achieved partial response (PR). Bortezomib containing regimen was associated with significantly deeper and more rapid response, (p=0.001 and p=0.017, respectively) when compared to other agents. Only 22.8% of these patients proceeded to upfront autologous haematopoietic stem cell transplantation. The median OS and PFS were 60.0 months and 25.0 months, respectively. Best initial response and upfront autologous stem cell transplantation (ASCT) were significantly associated with better PFS. Achieving at least a VGPR significantly associated with better outcome in NDMM patients. In a resource constrain country, we recommend incorporating bortezomib in the induction therapy followed with an upfront ASCT.

Effects of Pre-Transplant CONUT and Post-Transplant MRD on Prognosis of Patients with Multiple Myeloma after Auto-HSCT

To explore the effects of pre-transplant controlling nutritional status (CONUT) and post-transplant minimal residual disease (MRD) on prognosis of patients with multiple myeloma (MM) after autologous hematopoietic stem cell transplantation (auto-HSCT). The clinical data of 79 patients who received auto-HSCT from 2011 to 2020 in The First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The patients were divided into Low-CONUT group (n=62) and High-CONUT group (n=17) according to whether the CONUT score was less than 5. The differences in clinical features, hematopoietic reconstruction, adverse reactions, efficacy and survival between the two groups were compared. In addition, the prognostic risk factors were analyzed and verified by time-dependent ROC curve. The proportions of male patients and bone marrow plasma cells>30% at initial diagnosis in High-CONUT group were both higher than those in Low-CONUT group (both P <0.05). While, there were no significant differences in hematopoietic reconstruction and adverse reactions (>grade 2) between the two groups. The complete response (CR) rate and CR+very good partial response (VGPR) rate before transplantation in Low-CONUT group were both significantly higher than those in High-CONUT group (both P <0.05). After 3 months of transplantation, the CR+VGPR rate still remained an advantage in Low-CONUT group compared with High-CONUT group (P <0.01), but CR rate did not(P >0.05). The overall survival (OS) and progression-free survival (PFS) in Low-CONUT group were both superior to those in High-CONUT group (both P <0.05). Low CONUT score (0-4) before transplantation and negative MRD at 6 months after transplantation were favorable factors affecting OS and PFS (both P <0.05), while the International Myeloma Working Group (IMWG) high-risk at initial diagnosis and lactate dehydrogenase (LDH) level>250 U/L before transplantation were only risk factors for PFS (both P <0.05). Time-dependent ROC curve analysis showed that pre-transplant CONUT score and MRD status at 6 months after transplantation could independently or jointly predict 1- and 2-year OS and PFS, and the combined prediction was more effective. The combination of pre-transplant CONUT and post-transplant MRD can better predict the prognosis of MM patients.

Risk Factors and the Effect of Antiviral Prophylaxis for Herpes Zoster in Multiple Myeloma Patients

To study the incidence and risk factors of herpes zoster in patients with multiple myeloma and to evaluate the preventive effect of antiviral therapy. The clinical features of multiple myeloma patients with herpes zoster were retrospectively analyzed, the risk factors of herpes zoster and the effect of antiviral prophylaxis were analyzed. Among 180 patients with multiple myeloma, 23 cases developed herpes zoster (12.8%). The incidence of herpes zoster was 19.1% in patients with renal dysfunction and 23.5% after autologous hematopoietic stem cell transplantation (ASCT). The incidence of herpes zoster was higher in patients receiving bortezomib-containing regimens (21/137, 15.3%) than that in those without bortezomib (2/43, 4.7%), but there was no statistical difference (P =0.067). Antiviral prophylaxis was associated with fewer zoster infections, 8/111(7.2%) developed herpes zoster in patients who received antiviral prophylaxis, and 15/69 (21.7%) in those receiving no prophylaxis(P =0.005). 65.2% of patients with herpes zoster did not receive antiviral prophylaxis. Multivariate analysis showed that bortezomib treatment, AHSCT and renal dysfunction were independent risk factors for multiple myeloma with herpes zoster, while antiviral prophylaxis was independently associated with reducing the risk of herpes zoster. Herpes zoster had no effect on OS in patients with multiple myeloma. The risk of herpes zoster in multiple myeloma patients was increased. Antiviral prophylaxis can reduce the risk of herpes zoster in patients on bortezomib-based therapy.

High doses of chemotherapy and autologous hematopoietic stem cell transplantation in patients with relapsed/refractory testicular germ cell tumors: Multicenter real-world experience in Argentina.

508 Background: Germ cell tumors (GCTs) are the most common type of cancer in adolescent and young adult males. Most of them are curable with multimodal treatment: platinum-based chemotherapy (CT) + surgery. Patients who fail first-line treatment usually receive salvage CT with response rates between 30 and 50%. High-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDCT) is an effective treatment in this context. Methods: We conducted a multicenter retrospective analysis of patients ≥ 15 years old with relapsed/refractory GCTs who received HDCT in 13 centers of the Argentine Group of Bone Marrow Transplantation and Cellular Therapy (GATMO-TC) from 2010 to 2022. Results: 114 patients were included, with a median age of 32 years (range: 15-58). Most had non-seminoma histology (66%); The primary tumor site was testis (65%), retroperitoneum (17%), and mediastinum (9%). Forty percent (n:46) had an unfavorable prognosis according to the IGCCCG score. Eighty-two % received ≥ 2 lines of CT before HDCT, 27% being platinum-refractory disease (PRD), and 45% received 2 consecutive courses of HDCT (tandem). All patients received a carboplatin-etoposide-based conditioning regimen. The median engraftment time was 12 days (d) (r8;25) for neutrophils and 15 d (r6;58) for platelets. Bacteremia (25%) and Hepatotoxicity (14.9%) were the most frequent G3-4 adverse events. With a median follow-up of 12.6 months (r1-138), 100 pts were evaluable for survival. 12- and 24-months OS was 67%- 64%; and PFS 56%; - 54% respectively. PRD patients had worse OS and PFS. Eighteen patients remained alive and without relapsing beyond 5 years of follow-up. Conclusions: This real-world multicentric study demonstrates that some patients with refractory/relapsed metastatic GCT are curable by HDCT, being an effective and safe feasible treatment with response rates similar to those described in the literature. The superiority of the tandem approach could not be demonstrated due to the heterogeneity of the sample.[Table: see text]

Coping with stress styles and the level of perceived stress in hematopoietic cell transplant patients.

Hematopoietic stem cell transplantation (HSCT) is considered an integral part of therapy in many hematological and non-hematological malignancies. The procedure can be highly stressful for patients. The primary objective of this study was to compare stress assessments in HSCT patients, depending on their stress coping style (CS) and type of treatment (autologous vs. allogeneic HSCT). A short longitudinal study was conducted between May 2021 and June 2023 among patients with hematological cancers undergoing HSCT. The study involved four time points: the day of admission to hospital - T1, the day before HSCT - T2, 6days after HSCT - T3, and the day of discharge - T4. Participants completed the Coping Inventory for Stressful Situations (CISS) on T1, and the Distress Thermometer (DT) on T1-T4. Descriptive statistics and a repeated measures ANOVA were conducted. A total of 128 participants completed the study: 54.2% female, mean age 48.7years. They were divided into: (1) five groups based on their CS: task-oriented, emotion-oriented, avoidance-oriented, mix-oriented, differential-oriented; (2) two groups based on treatment type. The analyses showed significant differences in stress between the CS study groups (p=0.001). The emotion-oriented group had the highest stress levels during the hospitalization period. There was also a significant time effect (p<0.001): stress levels increased during the hospitalization period, peaking 6days after HSCT, and decreased at discharge. Stress levels depend on coping styles and time points during the hospitalization period, which should be taken into account in planning psychological interventions for HSCT patients.
