Previous trials testing prevention strategies for chronic graft versus host disease (GVHD) have measured its cumulative incidence. In this trial of anti-thymocyte globulin, we measured treatment-independence at a long-term timepoint as the primary endpoint.

Introduction

Introduction:FLT3 internal tandem duplication (ITD) mutations have been historically associated with inferior outcomes in patients with acute myeloid leukemia (AML) and an intermediate risk status as per the European LeukemiaNet (ELN) 2022 guidelines. In 2017, the US FDA granted approval to midostaurin for frontline treatment and a year later, gilteritinib for use in relapsed/refractory (R/R) AML. These agents began to be widely used in our provincial leukemia program in early 2018 as per the label indications. In this study, we compared clinical outcomes for patients with FLT3-ITD mutated AML before and after this change in British Columbia.

Introduction: Lung involvement in chronic graft versus host disease (cGVHD) is an uncommon but potentially devastating complication with significant morbidity and mortality in patients who have received an allogeneic hematopoietic stem cell transplant (alloHSCT). Unfortunately, early detection remains difficult as early lung cGVHD tends to be asymptomatic or present with nonspecific symptoms such as cough or mild shortness of breath. In British Columbia (BC), Canada, routine pulmonary function tests (PFTs) have been employed in the screening of lung cGVHD in this population at an interval of every 3-4 months for the first 2-3 years after alloHSCT. However, it is unknown whether routine screening 1) improves detection of lung cGVHD, and 2) enables earlier intervention to lead to better outcomes. We aimed to assess the real-world outcomes of lung cGVHD screening and compared the characteristics and clinical results of patients who had lung cGVHD detected via routine PFT screening, versus those who were detected after development of symptoms.

Background:

Chronic graft-versus-host disease (cGVHD) remains one of the most significant long-term complications after allogeneic blood and marrow transplantation. Diagnostic biomarkers for cGVHD are needed for early diagnosis and may guide identification of prognostic markers. No cGVHD biomarker has yet been validated for use in clinical practice. We evaluated both previously known markers and performed discovery-based analysis for cGVHD biomarkers in a 2 independent test sets (total of 36 cases ≤1 month from diagnosis and 31 time-matched controls with no cGVHD). On the basis of these results, 11 markers were selected and evaluated in 2 independent replication cohorts (total of 134 cGVHD cases and 154 controls). cGVHD cases and controls were evaluated for several clinical covariates, and their impact on biomarkers was identified by univariate analysis. The 2 replications sets were relatively disparate in the biomarkers they replicated. Only sBAFF and, most consistently, CXCL10 were identified as significant in both replication sets. Other markers identified as significant in only 1 replication set included intercellular adhesion molecule 1 (ICAM-1), anti-LG3, aminopeptidase N, CXCL9, endothelin-1, and gelsolin. Multivariate analysis found that all covariates evaluated affected interpretation of the biomarkers. CXCL10 had an increased significance in combination with anti-LG3 and CXCL9, or inversely with CXCR3+CD56bright natural killer (NK) cells. There was significant heterogeneity of cGVHD biomarkers in a large comprehensive evaluation of cGVHD biomarkers impacted by several covariates. Only CXCL10 strongly correlated in both replication sets. Future analyses for plasma cGVHD biomarkers will need to be performed on very large patient groups with consideration of multiple covariates.

This randomized phase 3 clinical trial evaluated the potential benefit of the addition of gemtuzumab ozogamicin (GO) to standard induction and postconsolidation therapy in patients with acute myeloid leukemia. Patients were randomly assigned to receive daunorubicin (45 mg/m2 per day on days 1, 2, and 3), cytarabine (100 mg/m2 per day by continuous infusion on days 1–7), and GO (6 mg/m2 on day 4; DA+GO) vs standard induction therapy with daunorubicin (60 mg/m2 per day on days 1, 2, and 3) and cytarabine alone (DA). Patients who achieved complete remission (CR) received 3 courses of high-dose cytarabine. Those remaining in CR after consolidation were randomly assigned to receive either no additional therapy or 3 doses of GO (5 mg/m2 every 28 days). From August 2004 until August 2009, 637 patients were registered for induction. The CR rate was 69% for DA+GO and 70% for DA (P = .59). Among those who achieved a CR, the 5-year relapse-free survival rate was 43% in the DA+GO group and 42% in the DA group (P = .40). The 5-year overall survival rate was 46% in the DA+GO group and 50% in the DA group (P = .85). One hundred seventy-four patients in CR after consolidation underwent the postconsolidation randomization. Disease-free survival was not improved with postconsolidation GO (HR, 1.48; P = .97). In this study, the addition of GO to induction or postconsolidation therapy failed to show improvement in CR rate, disease-free survival, or overall survival. This trial is registered with www.clinicaltrials.gov as #NCT00085709.

Intro:Iron overload (IO) reflected by elevated serum ferritins is associated with increased mortality in patients with myelodysplastic syndromes (MDS) with a threshold effect seen above 1000 ug/ml (Malcovati, JCO 2005). Ferritin is elevated due to transfusions, inflammation and ineffective erythropoiesis but is an imperfect metric of true iron overload. Elevated levels of oxidatively damaging non-transferrin bound iron (NTBI) and labile plasma iron (LBI) are not easily measured but correlate with transferrin saturation (TSAT) >70% and >80% respectively (de Swart, Haematological 2018). The relationship of TSAT with ferritin and MDS-related clinical outcomes has not been well-characterized.

Beginning in 1985, patients in British Columbia with Hodgkin lymphoma (HL) that was not controlled by conventional chemotherapy routinely underwent high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT). Long-term complications of HD-ASCT have become apparent as more patients survive without recurrence of HL. Data were obtained retrospectively on the first 100 patients that underwent HD-ASCT for HL in Vancouver, focusing on relapse, treatment-related complications, and the occurrence of late events. Fifty-three patients remain alive (median follow-up, 11.4 years [range, 10.0-17.4 years]) with an overall survival (OAS) of 54% at 15 years. OAS was significantly better in patients in first relapse (67%) than in patients with primary refractory-induction failure (39%) and advanced disease (29%) (P = .002). The major cause of death was progression of HL (32% at 15 years). Treatment-related mortality, including death from second malignancy, was 17% at 15 years. Cumulative risk of a second malignancy was 9% at 15 years. Karnofsky performance status was at least 90% in 47 patients although hypogonadism (20 patients), hypothyroidism (12 patients), unusual infections (10 patients), anxiety or depression (7 patients), and cardiac disease (5 patients) were not uncommon in survivors. HD-ASCT can lead to durable remissions in relapsed or refractory HL with acceptable but definite late toxicity. The occurrence of late events necessitates lifelong medical surveillance.

Although numerous reports indicate that patients receiving autotransplants for lymphoma are at increased risk for myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML), the separate contributions of pretransplantation- and transplantation-related therapy are not well characterized. We conducted a case-control study of 56 patients with MDS/AML and 168 matched controls within a cohort of 2 739 patients receiving autotransplants for Hodgkin disease or non-Hodgkin lymphoma at 12 institutions (1989-1995). Detailed abstraction of medical records was undertaken to determine all pre- and posttransplantation therapy, and transplantation-related procedures. In multivariate analyses, risks of MDS/AML significantly increased with the intensity of pretransplantation chemotherapy with mechlorethamine (relative risks [RRs] = 2.0 and 4.3 for cumulative doses < 50 mg/m2and ≥ 50 mg/m,2respectively; trend over dose categories, P= .04) or chlorambucil (RRs = 3.8 and 8.4 for duration < 10 months or ≥ 10 months, respectively; trend, P= .009), compared with cyclophosphamide-based therapy. Transplantation-conditioning regimens including total-body irradiation (TBI) at doses 12 Gy or less did not appear to elevate leukemia risk (RR = 1.3; P= .48) compared with non-TBI regimens; however, a statistically significant increased risk was found for TBI doses of 13.2 Gy (RR = 4.6; P= .03). Peripheral blood stem cells were associated with a nonsignificant increased risk of MDS/AML (RR = 1.8; P= .12) compared with bone marrow grafts. Our data show that type and intensity of pretransplantation chemotherapy with alkylating agents are important risk factors of MDS/AML following autotransplantation. Transplantation-related factors may also modulate this risk; however, the apparent contribution of high-dose TBI requires confirmation.

Allogeneic bone marrow transplantation (BMT) is the only curative therapy available for patients with myelodysplastic syndrome (MDS). In an attempt to identify prognostic factors influencing outcome, we collected data retrospectively on 60 consecutive adult patients who had undergone BMT at our center for primary MDS or acute myelogenous leukemia evolving from preexisting primary MDS (sAML). Patients were divided into subgroups according to cytogenetic abnormalities based on a recently described International MDS Workshop categorization system. The 7-year actuarial event-free survival (EFS), relapse rate, and nonrelapse mortality (NRM) for all patients were 29% (95% confidence interval [CI], 16% to 43%), 42% (CI, 24% to 67%), and 50% (CI, 37% to 64%), respectively. The EFS for the good-, intermediate-, and poor-risk cytogenetic subgroups were 51% (CI, 30% to 69%), 40% (CI, 16% to 63%), and 6% (CI, 0% to 24%), respectively (P= .003). The corresponding actuarial relapse rates were 19% (CI, 6% to 49%), 12% (CI, 2% to 61%), and 82% (CI, 48% to 99%), respectively (P = .002) with no difference in NRM between the subgroups. Univariate analysis showed cytogenetic category, French-American-British (FAB) subtype, and graft-versus-host disease (GVHD) prophylaxis used to be predictive of relapse and EFS. In multivariate analysis, only the cytogenetic category was predictive of EFS, with the relative risk of treatment failure for the good-, intermediate-, and poor-risk cytogenetic subgroups being 1.0, 1.5, and 3.5, respectively (P = .004). For adults with primary MDS and sAML, even after BMT, poor-risk cytogenetics are predictive of an unfavorable outcome; novel treatment strategies will be required to improve results with allogeneic BMT in this patient population. © 1998 by The American Society of Hematology.

Background: We previously reported that pretreatment with rabbit anti-thymocyte globulin (ATG) decreases the use of immunosuppressive therapy (IST) and occurrence of chronic graft-versus-host disease (GVHD) 12 months after allogeneic stem cell transplantation from unrelated donors. We hypothesized these benefits would persist beyond 12 months with a positive clinical impact on patients.

Background:More than 50% of patients with myelodysplastic syndrome (MDS) become transfusion dependent (TD) during the course of their disease and 25-30% present as TD at diagnosis. While TD is more common in IPSS/IPSS-R higher risk patients and is associated with inferior overall survival, it is unclear if achievement of transfusion independence (TI) for even short periods of time is associated with improved overall survival (OS).

Introduction:

In a real-world audit of azacitidine (AZA) in higher risk myelodysplasia (MDS) and oligoblastic acute myeloid leukemia (AML) (Mozessohn et al.2016), 410 of 1101 patients (33%) did not reach the fourth cycle of treatment and had a median overall survival (OS) of 3 months compared to 17 months in those completing ≥ 4 cycles. While early disease progression may account for premature discontinuation, it is plausible that patient related factors including co-morbidities and frailty also contribute. To maximize cost-effectiveness and minimize toxicity, it is necessary to identify patients more likely to complete 4 cycles of AZA. MDS-CAN is a national, prospective registry collecting disease and patient-specific information every 6-12 months. Patient-related factors measured yearly include frailty (Rockwood clinical frailty scale (CFS), comorbidity (Charlson CI and MDS-CI), disability (Lawton-Brody SIADL) and physical performance (4 meter walk test, grip strength, 10 x timed chair-sit test).

Introduction: Post-remission therapy (PRT) for acute myeloid leukemia (AML) remains an area of debate. Autologous stem cell transplantation (AutoSCT) is listed as a possible PRT in patients with intermediate risk AML in the 2017 European Leukemia Network Recommendations. Our center has frequently performed AutoSCT for patients with AML and we aimed to retrospectively compare this strategy with allogeneic SCT (AlloSCT) and consolidation chemotherapy (CMT).

Background: In the clinic, the prognostication for the survival of MDS patients is primarily determined using the IPSS and IPSS-R which are based on disease-related characteristics. Our group has previously demonstrated that the Charlson comorbidity index (CCI) and the Rockwood 9-point clinical frailty scale (CFS) are independently prognostic for overall survival (OS) in MDS patients. The CFS was used dichotomously since only 25% of patients fell within the vulnerable or frail categories. The frailty index (FI) is a popular method for measuring frailty in geriatrics and is strongly associated with the risk of adverse outcomes including death. The FI uses an accumulation of deficits approach based on the principle that the more deficits an individual has, the greater their frailty is. An individual's FI score is expressed as a ratio of deficits present to total number of deficits considered with a recommended consideration of 30 deficits.

Background: Burkitt lymphoma (BL) is a highly aggressive non-Hodgkin lymphoma associated with translocations involving the c-MYC oncogene on chromosome 8. The 1996 Magrath regimen, CODOX-M/IVAC, showed a promising 2-year (y) event free survival (EFS) of 92% in 41 BL patients (pts), with additional trials of a dose-modified regimen demonstrating 2y overall survival (OS) 70-82% and 2y progression-free survival (PFS) 64% (Mead et al). A recent trial demonstrated that with addition of R, 3y OS and EFS were 83% and 75% (Ribrag et al). We sought to determine survival outcomes of adult BL pts in BC treated with CODOX-M/IVAC +/- R to evaluate the effectiveness of this regimen on a population basis.
