Improvement in survival in Light chain (AL) amyloidosis has been seen over recent decades, enabling more patients to achieve long-term survival. Patients with AL amyloidosis who survived ≥10 years from time of diagnosis (n = 186) were the subject of this study. Ten-year survivors represented 22% of the total population. These patients were characterized by favourable patient, organ and plasma cell features. Of note, trisomies were less common among 10-year survivors compared to those who did not survive to 10 years...

Bortezomib in combination with cyclophosphamide and dexamethasone (CyBorD, is a well-established frontline chemotherapy regimen for patients with multiple myeloma, but prospective data on elderly non-transplant eligible patients is limited. A total of 155 patients aged 70 years or older with newly diagnosed multiple myeloma who received at least one cycle of CyBorD chemotherapy in three centres across New Zealand were evaluated. Partial response or better was achieved in 79·4%, of whom 52·9% achieved at least a very good partial response...

This study describes the use of a simple charcoal product (DOAC-RemoveTM ) to allow haemostasis assays on patients taking direct oral anticoagulants (DOAC). In the proposed algorithm, patients taking DOAC are screened using the dilute thrombin time (dTT) and anti-Xa assay. If either are positive then DOAC-Remove is utilised. In a validation, DOAC-Remove did not interfere with coagulation testing in normal plasma or in patients on DOAC with a known lupus anticoagulant (LA). Of 1566 routine patient samples tested, 125 (8%) had evidence of anti-Xa activity (>0·1 iu/ml) or prolonged dTT suggestive of either a direct/indirect Xa inhibitor or direct thrombin inhibitor...

Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) after, or ineligible for, autologous stem cell transplantation (ASCT) have a dismal prognosis. This phase II study evaluated treatment with R-PECC (rituximab, prednisolone, etoposide, chlorambucil, lomustine), every 28 days for 4 cycles in 62 patients, followed by radio-immunotherapy consolidation with 90 Y-ibritumomab tiuxetan in responsive patients. Primary endpoints were failure-free survival (FFS) and incidence of grade ≥3 adverse events from start of 90 Y-ibritumomab tiuxetan...

IgM monoclonal gammopathies of undetermined significance (IgM MGUS) are associated with a risk of progression to Waldenström macroglobulinaemia (WM) or other lymphoproliferative disorders (LPD) of 1-2% per year. We analysed 176 consecutive patients with IgM MGUS to evaluate risk factors for progression. With a median follow-up of 83 months (1214 person-years), 15 patients (8·5%) progressed to WM (n = 14) or marginal zone lymphoma (n = 1). The rate of progression was 1·32% per year (95% confidence interval [CI] 0·80-2·20)...

Hereditary spherocytosis (HS) is characterised by increased osmotic fragility and enhanced membrane loss of red blood cells (RBC) due to defective membrane protein complexes. In our diagnostic laboratory, we observed that pyruvate kinase (PK) activity in HS was merely slightly elevated with respect to the amount of reticulocytosis. In order to evaluate whether impaired PK activity is a feature of HS, we retrospectively analysed laboratory data sets from 172 unrelated patients with HS, hereditary elliptocytosis (HE), glucose-6-phosphate dehydrogenase (G6PD) or PK deficiency, sickle cell or haemoglobin C disease, or β-thalassaemia minor...

The effectiveness of tyrosine kinase inhibitors (TKIs) has made it possible to consider treatment discontinuation in chronic myeloid leukaemia (CML) patients that achieve an excellent response. However, a few of the patients included in the Europe Stop Tyrosine Kinase Inhibitors (EURO-SKI) trial reported musculoskeletal pain shortly after stopping TKIs, considered as a withdrawal syndrome (WS). To identify factors that may predispose to TKI WS, we analysed the pharmacovigilance declarations for the 6 months after stopping TKIs in a large cohort of CML (n = 427) that combined the French patients included in the STop IMatinib 2 (STIM2; n = 224) and EURO-SKI (n = 203) trials...

This study aimed to clarify the comprehensive clinical, laboratory, pathological and imaging features of intravascular large B-cell lymphoma (IVLBCL) using data on 42 IVLBCL patients diagnosed at our hospital over the past 20 years. The majority of patients were diagnosed via random skin biopsy (29/42, 69·0%) followed by bone marrow biopsy alone (8/42, 19·0%). Characteristic features included persistent fever (41/42, 97·6%), decreased performance status (≥2) (100%), hypoxaemia (32/40, 80·0%), impaired consciousness (19/42, 45·2%), hypoalbuminemia (42/42, 100%) and extreme elevation of lactate dehydrogenase and soluble interleukin 2 receptor levels...

Ibrutinib is associated with response rate of 90% and median progression-free survival (PFS) in excess of 5 years in Waldenström macroglobulinaemia (WM) patients. CXCR4 mutations are detected in 30-40% of patients with WM and associate with lower rates of response and shorter PFS to ibrutinib therapy. Both frameshift (CXCR4FS ) and nonsense (CXCR4NS ) CXCR4 mutations have been described. The impact of these mutations on outcomes to ibrutinib have not been evaluated in WM patients. We studied consecutive patients with a diagnosis of WM, on ibrutinib therapy, for the presence of CXCR4FS and CXCR4NS mutations and evaluated the differences in response and PFS between groups...

Follicular lymphoma (FL) is the most common indolent lymphoma. Currently there are many comparable treatment options available for FL. When selecting the most optimal therapy it is important to consider possible late effects of the treatment as well as survival. Secondary haematological malignancy (SHM) is a severe late effect of treatments, but the incidence of SHMs is still largely unknown. The goal of the present study was to determine the incidence of SHMs and how therapeutic decisions interfere with this risk...

The measurement of homocysteine is still part of routine thrombosis or thrombophilia work-up in many thrombosis centres in the world. Previous observational studies have shown that hyperhomocysteinaemia is associated with an increased risk of first and recurrent venous thrombosis (VT). Randomised trials, however, showed no benefit of homocysteine-lowering therapy on the risk of first or recurrent VT. This discrepancy could be explained by incomplete adjustment for confounders in the observational studies. We investigated in a large population-based follow-up study whether if the levels of homocysteine and its metabolites, methionine and cysteine, were associated with recurrent VT...

Despite the importance of a prompt diagnosis to improve cancer patients' survival, little has been reported on diagnostic delay in diffuse large B-cell lymphoma (DLBCL). A single-centre, retrospective study was conducted to examine the association between diagnostic wait time (DWT), the interval from the initial hospital visit to diagnosis, and survival in patients with DLBCL. A total of 193 patients were enrolled from 2007 to 2017 in our institution. A covariate-adjusted Cox proportional hazards model with restricted cubic spline was used to evaluate the impact of DWT on survival, with a subgroup analysis according to the International Prognostic Index (IPI)...

We performed a retrospective analysis of leukaemic surface antigen expression and genomic data from a total of 100 RUNX1-RUNX1T1-positive paediatric acute myeloid leukaemia (AML) patients enrolled in the Japanese Paediatric Leukaemia/Lymphoma Study Group (JPLSG) AML-05 protocol to determine risk factors for relapse. In univariate analysis, the KIT exon 17 mutation (n = 21) and CD19 negativity (n = 59) were significant risk factors for relapse (P = 0·01). In multivariate analysis, CD19 negativity was the sole significant risk factor for relapse (hazard ratio, 3·09; 95% confidence interval, 1·26-7·59; P < 0·01), suggesting that biological differences between CD19-positive and CD19-negative RUNX1-RUNX1T1 AML patients should be investigated...
