Rituximab-containing chemotherapy regimens constitute standard first-line therapy for mantle cell lymphoma (MCL). Since June 2013, 190 patients ≥18 years of age with MCL in British Columbia have been treated with bendamustine and rituximab (BR). The overall response rate to BR was 88% (54% complete response). Of these, 61 of 89 patients (69%) aged ≤65 years received autologous stem cell transplantation and 141 of 190 patients (74%) from the entire cohort received maintenance rituximab. Twenty-three patients (12%) had progressive disease, associated with high risk per the Mantle Cell Lymphoma International Prognostic Index (MIPI), Ki-67 ≥50%, and blastoid/pleomorphic histology. Outcomes were compared with a historical cohort of 248 patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP; January 2003 to May 2013). Treatment with BR was associated with significant improvements in progression-free survival (PFS), but not overall survival (OS), compared with R-CHOP in the whole cohort (3-year PFS, 66% BR vs 51% R-CHOP, P = .003; 3-year OS, 73% BR vs 66% R-CHOP, P = .054) and in those >65 years of age (3-year PFS, 56% BR vs 35% R-CHOP, P = .001; 3-year OS, 64% BR vs 55% R-CHOP, P = .063). Outcomes in transplanted patients were not statistically significantly different compared with R-CHOP (3-year PFS, 85% BR vs 76% R-CHOP, P = .135; 3-year OS, 90% BR vs 88% R-CHOP, P = .305), although in multivariate analyses, treatment with BR was associated with improved PFS (hazard ratio, 0.40 [95% confidence interval, 0.17-0.94]; P = .036) but not OS. BR is an effective first-line option for most patients with MCL, however, outcomes are suboptimal for those with high-risk features and further studies integrating novel agents are warranted.

NOTCH1is recurrently mutated in chronic lymphocytic leukemia (CLL), most commonly as a 2-bp frameshift deletion (c.7541_7542delCT). This mutated allele encodes a truncated form of the receptor (p.P2514Rfs∗4) lacking the C-terminal proline, glutamic acid, serine, and threonine (PEST) degradation domain that increases NOTCH1signaling duration. NOTCH1mutation has been associated with poor clinical outcomes in CLL. We validated a highly sensitive and quantitative droplet digital PCR assay for the NOTCH1delCT mutation, which was anticipated to perform well compared with Sanger sequencing and allele-specific PCR. Performance characteristics of this assay were tested on 126 samples from an unselected CLL cohort and a separate cohort of 85 samples from patients with trisomy 12 CLL. The delCT mutation was detected at allele frequencies as low as 0.024%; 25% of unselected cases and 55% of trisomy 12 cases were positive at the 0.024% detection threshold. Mutational burdens ≥1% were significantly associated with shorter overall survival (OS) in patients with trisomy 12+ disease in multivariate analysis (median OS, 9.1 versus 13 years, with hazard ratio of 2.34; P = 0.031). Mutational burdens <1% correlated with shorter OS in univariate, but not multivariate, analyses. These results suggest that droplet digital PCR testing for NOTCH1delCT mutation may aid in risk stratification and/or disease monitoring in certain subsets of patients with CLL.

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:Richter transformation (RT) to diffuse large B-cell lymphoma (DLBCL) is a well-known complication of CLL/SLL, occurring in 2-10% of patients (pts); however, a minority transform to Hodgkin lymphoma, termed Hodgkin variant of RT (HvRT). Because of the rarity of HvRT, there is limited information regarding prognostic factors and treatment approach. The aim of this study was to evaluate clinical characteristics, treatment and survival of HvRT in a population based cohort of CLL/SLL pts in BC.

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.

Familial platelet disorder with propensity to myeloid malignancy (FPD/AML) is an autosomal dominant syndrome characterized by platelet abnormalities and a predisposition to myelodysplasia (MDS) and/or acute myeloid leukemia (AML). The disorder, caused by inherited mutations in RUNX1, is uncommon with only 14 pedigrees reported. We screened 10 families with a history of more than one first degree relative with MDS/AML for inherited mutations in RUNX1. Germ- line RUNX1 mutations were identified in 5 pedigrees with a 3:2 predominance of N-terminal mutations. Several affected members had normal platelet counts or platelet function, features not previously reported in FPD/AML. The median incidence of MDS/AML among carriers of RUNX1 mutation was 35%. Individual treatments varied but included hematopoietic stem cell transplantation from siblings before recognition of the inherited leukemogenic mutation. Transplantation was associated with a high incidence of complications including early relapse, failure of engraftment, and posttransplantation lymphoproliferative disorder. Given the small size of modern families and the clinical heterogeneity of this syndrome, the diagnosis of FPD/AML could be easily overlooked and may be more prevalent than previously recognized. Therefore, it would appear prudent to screen young patients with MDS/AML for RUNX1 mutation, before consideration of sibling hematopoietic stem cell transplantation.

Background:Ibrutinib has dramatically changed the treatment landscape for relapsed/refractory (R/R) and newly diagnosed CLL/SLL patients (pts), leading to durable remissions in the majority of pts; however, this comes at a high cost to the healthcare system particularly since treatment is continued until progression. Ibrutinib has been available in BC on compassionate access basis since 2014, publicly funded for R/R CLL/SLL or upfront for pts with deletion 17p (del17p) since 2016, and as upfront therapy in fludarabine-ineligible pts since 2018. In view of Ibrutinib's widespread use and rapid uptake among BC physicians, we sought to investigate discontinuation rates, dose modifications, and overall survival (OS) with introduction of ibrutinib within the publicly funded BC healthcare system.

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.

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

Background:Oral fludarabine and intravenous rituximab (FR) was the standard first-line therapy for CLL or small lymphocytic lymphoma (SLL) patients (pts) in BC from 2003-2015. Ibrutinib for relapsed/refractory (R/R) CLL was introduced and publicly funded in 2015. Our aim was to review long term outcomes of all CLL/SLL pts treated with FR in BC, including the impact of 2ndline therapy with ibrutinib versus chemoimmunotherapy and to report the risk of secondary malignancies in this population based cohort.

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:

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.
