The detection rates of whole-body combined [ 18 F]NaF/[ 18 F]FDG positron emission tomography combined with computed tomography (PET/CT), CT alone, whole-body magnetic resonance imaging (WB-MRI), and X-ray were prospectively studied in patients with treatment-requiring plasma cell disorders The detection rates of imaging techniques were compared, and focal lesions were classified according to their anatomic location. Twenty-six out of 30 initially included patients were assessable. The number of focal lesions detected in newly diagnosed patients (n = 13) and in relapsed patients (n = 13) were 296 and 234, respectively. The detection rate of PET/CT was significantly higher than those of WB-MRI (P < 0.05) and CT (P < 0.0001) both in patients with newly diagnosed and in those with relapsed multiple myeloma (MM). The X-ray detection rate was significantly lower than those of all other techniques, while CT detected more lesions compared with WB-MRI at diagnosis (P = 0.025). With regard to the infiltration patters, relapsed patients presented more diffuse patterns, and more focal lesions located in the limbs compared with newly diagnosed patients. In conclusion, the detection rate of [ 18 F]NaF/[ 18 F]FDG PET/CT was significantly higher than those of CT, MRI, and X-ray, while the detection rate of X-rays was significantly lower than those of all other imaging techniques except for focal lesions located in the skull. © 2019 John Wiley & Sons, Ltd.

CNS relapse is reported in 2–5% of diffuse large B-cell lymphoma (DLBCL) patients, dramatically decreasing overall survival (OS). Very few studies address incidence and risk factors of CNS relapse in very elderly patients, a challenging population to treat given their commonly associated comorbidities. A retrospec-tive analysis was performed of 270 DLBCL patients >80years treated between 2004 and 2013 in two multicentre phase II LYSA trials (LNH03-7B, LNH09-7B) evaluating the addition of rituximab or ofatumumab to mini-CHOP as front-line therapy. No patients received CNS prophylaxis. CNS relapse was evaluated according to cumulative incidence, patient characteristics, risk factors, and sur-vival. Median age was 83years (range: 79–95). After a median follow-up of 28.7months, eight patients had CNS relapse (3.0%). Median time between inclusion and CNS relapse was 19.2months (range: 3.2–32.6). Patients survived a median of 1.5months after CNS relapse (range: 0.4–4.1). Median OS from relapse was significantly lower in CNS relapse patients (1.5months, 95% CI: 0.4–3.5) compared to patients with non-CNS relapse (6.6months; 95% CI: 4.6–11.9). No baseline characteristics were associated with CNS relapse. The proportion of patients with CNS disease did not differ significantly between patients with low- intermediate risk according to CNS- IPI and patients with high risk (3% vs. 2.8%, P = 1.00). CNS relapse cumulative incidence in very elderly treatment- naive patients is 1.8% at 2 years and is associated with poor survival. This population had a long median time to CNS relapse. Absence of prophylaxis did not strongly impact CNS relapse incidence. [less ▲]

Background: Peripheral T-cell lymphoma (PTCL) remains a therapeutic challenge. Due to the rarity and the heterogeneity of PTCL, no consensus has been achieved regarding even the type of first-line treatment. The benefit of autologous stem-cell transplantation (ASCT) is, therefore, still intensely debated. Patients and methods: In the absence of randomized trials addressing the role of ASCT, we performed a large multicentric retrospective study and used both a multivariate proportional hazard model and a propensity score matching approach to correct for sample selection bias between patients allocated or not to ASCT in intention-to-treat (ITT). Results: Among 527 patients screened from 14 centers in France, Belgium and Portugal, a final cohort of 269 patients 65 years old with PTCL-not otherwise specified (NOS) (N¼78, 29%), angioimmunoblastic T-cell lymphoma (AITL) (N¼123, 46%) and anaplastic lymphoma kinase-positive anaplastic large cell lymphoma (ALK-ALCL) (N¼68, 25%) with partial (N¼52, 19%) or complete responses (N¼217, 81%) after induction was identified and information about treatment allocation was carefully collected before therapy initiation from medical records. One hundred and thirty-four patients were allocated to ASCT in ITT and 135 were not. Neither the Cox multivariate model (HR¼1.02; 95% CI: 0.69–1.50 for PFS and HR¼1.08; 95% CI: 0.68– 1.69 for OS) nor the propensity score analysis after stringent matching for potential confounding factors (logrank P¼0.90 and 0.66 for PFS and OS, respectively) found a survival advantage in favor of ASCT as a consolidation procedure for patients in response after induction. Subgroup analyses did not reveal any further difference for patients according to response status, stage disease or risk category. Conclusions: The present data do not support the use of ASCT for up-front consolidation for all patients with PTCL-NOS, AITL, or ALK-ALCL with partial or complete response after induction. [less ▲]

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of aggressive non-Hodgkin lymphomas with poor outcomes on current therapy. We investigated whether response assessed with PET/CT combined with baseline total metabolic tumor volume (TMTV) could detect early relapse or refractory disease. Methods: From 7 European centers, 140 patients with nodal PTCL who underwent baseline PET/CT were selected. Forty-three had interim PET (iPET) performed after 2 cycles (iPET2), 95 had iPET performed after 3 or 4 cycles (iPET3/4), and 96 had end-of-treatment PET (eotPET). Baseline TMTV was computed with a 41% SUVmax threshold, and PET response was reported using the Deauville 5-point scale. Results: With a median of 43 mo of follow-up, the 2-y progression-free survival (PFS) and overall survival (OS) were 51% and 67%, respectively. iPET2-positive patients (Deauville score ≥ 4) had a significantly worse outcome than iPET2-negative patients (P < 0.0001, hazard ratio of 6.8 for PFS; P < 0.0001, hazard ratio of 6.6 for OS). The value of iPET3/4 was also confirmed for PFS (P < 0.0001) and OS (P < 0.0001). The 2-y PFS and OS for iPET3/4-positive (n = 28) and iPET3/4-negative (n = 67) patients were 16% and 32% versus 75% and 85%, respectively. The eotPET results also reflected patient outcome. A model combining TMTV and iPET3/4 stratified the population into distinct risk groups (TMTV ≤ 230 cm3 and iPET3/4-negative [2-y PFS/OS, 79%/85%]; TMTV > 230 cm3 and iPET3/4-negative [59%/84%]; TMTV ≤ 230 cm3 and iPET3/4-positive [42%/50%]; TMTV > 230 cm3 and iPET3/4-positive [0%/18%]). Conclusion: iPET response is predictive of outcome and allows early detection of high-risk PTCL patients. Combining iPET with TMTV improves risk stratification in individual patients. [less ▲]

Introduction: Mantle cell lymphoma is a B-cell non-Hodgkin’s lymphoma characterized by a t(11;14), resulting in overexpression of cyclin D1. Conventional chemotherapy obtains frequent (but short) remissions, leading to a poor median overall survival (OS) of 3–5 years. To obtain more information about the prevalence and current treatment of Mantle cell lymphoma (MCL) in Belgium, we collected data in a Belgian registry of MCL. Materials and methods: All Belgian MCL patients, t(11;14) and/or cyclin D1 positive, seen in hematology departments over a one-year period (April 2013–March 2014) were included. Data about patient characteristics, histology, treatment lines, and response were compiled and retrospectively analyzed. Results: Four hundred and four patients were included with a median age at diagnosis of 64 years (range 23–96 years) and a male predominance (72%). For 2013, we calculated a prevalence of at least 36.2 per million and an incidence of at least 7.0 per million in the Belgian population. Characteristics at diagnosis involved lymphadenopathy (82%), splenomegaly (44%), B-symptoms (39%), and hepatomegaly (10%). Bone marrow invasion was present at diagnosis in 77%. Stage at diagnosis was advanced in the majority of cases. The median number of treatment lines was 1. Type of first line treatment included a combination of anthracyclin and cytarabinebased regimen (34%), anthracyclin (39%), and other. Rituximab was used in 88% of first line treatments. In 44% first line treatment was followed by autologous stem cell transplantation. Conclusion: The analysis of this Belgian MCL registry provides insight in the epidemiology, demographics, and current treatment of our Belgian MCL population. [less ▲]

An observational study was set up to assess the feasibility of [(18)F]FPRGD2 PET/CT for imaging patients with multiple myeloma (MM) and to compare its detection rate with low dose CT alone and combined [(18)F]NaF/[(18)F]FDG PET/CT images. Four patients (2 newly diagnosed patients and 2 with relapsed MM) were included and underwent whole-body PET/CT after injection of [(18)F]FPRGD2. The obtained images were compared with results of low dose CT and already available results of a combined [(18)F]NaF/[(18)F]FDG PET/CT. In total, 81 focal lesions (FLs) were detected with PET/CT and an underlying bone destruction or fracture was seen in 72 (89%) or 8 (10%) FLs, respectively. Fewer FLs (54%) were detected by [(18)F]FPRGD2 PET/CT compared to low dose CT (98%) or [(18)F]NaF/[(18)F]FDG PET/CT (70%) and all FLs detected with [(18)F]FPRGD2 PET were associated with an underlying bone lesion. In one newly diagnosed patient, more [(18)F]FPRGD2 positive lesions were seen than [(18)F]NaF/[(18)F]FDG positive lesions. This study suggests that [(18)F]FPRGD2 PET/CT might be less useful for the detection of myeloma lesions in patients with advanced disease as all FLs with [(18)F]FPRGD2 uptake were already detected with CT alone.

Angioimmunoblastic T-cell lymphoma (AITL) and other lymphomas derived from follicular T-helper cells (TFH) represent a large proportion of peripheral T-cell lymphomas (PTCLs) with poorly understood pathogenesis and unfavorable treatment results. We investigated a series of 85 patients with AITL (n 5 72) or other TFH-derived PTCL (n 5 13) by targeted deep sequencing of a gene panel enriched in T-cell receptor (TCR) signaling elements. RHOA mutations were identified in 51 of 85 cases (60%) consisting of the highly recurrent dominant negative G17V variant in most cases and a novel K18N in 3 cases, the latter showing activating properties in in vitro assays. Moreover, half of the patients carried virtually mutually exclusive mutations in other TCR-related genes, most frequently in PLCG1 (14.1%), CD28 (9.4%, exclusively in AITL), PI3K elements (7%), CTNNB1 (6%), and GTF2I (6%). Using in vitro assays in transfected cells, we demonstrated that 9 of 10 PLCG1 and 3 of 3 CARD11 variants induced MALT1 protease activity and increased transcription from NFAT or NF-kB response element reporters, respectively. Collectively, the vast majority of variants in TCR-related genes could be classified as gain-of-function. Accordingly, the samples with mutations in TCR-related genes other than RHOA had transcriptomic profiles enriched in signatures reflecting higher T-cell activation. Although no correlationwithpresenting clinical featuresnor significantimpacton survivalwasobserved, thepresenceofTCR-relatedmutations correlated with early disease progression. Thus, targeting of TCR-related eventsmay hold promise for the treatment of TFH-derived lymphomas. [less ▲]

Large granular lymphocyte and prolymphocytic leukaemias are rare chronic lymphoproliferative disorders. Large granular lymphocyte leukaemias consist of indolent disorders such as T-cell large granular lymphocyte and chronic lymphoproliferative disorder of natural killer cells and the very rare but aggressive natural killer cell leukaemia. Treatment of the indolent large granular lymphocyte leukaemias is necessary in case of symptomatic cytopaenias or non-haematological autoimmune disorders. First line therapy of these two disorders is based on three immunosuppressive drugs: methotrexate, cyclophosphamide and cyclosporine A. Aggressive natural killer cell leukaemia needs an L-asparaginase containing regimen as induction followed by allogeneic stem cell transplantation to prolong remission. T-cell prolymphocytic leukaemia always follows an aggressive course even after an indolent onset. The optimal treatment strategy should exist of remission induction with alemtuzumab intravenously followed by autologous or allogeneic stem cell transplantation. Treatment indications for B-cell prolymphocytic leukaemia follow the criteria described by the chronic lymphocytic leukaemia guidelines. After induction with fludarabine, cyclophosphamide, rituximab or bendamustine in patients without a p53 mutation and/or a 17p deletion and alemtuzumab in case of a p53 mutation and/or a 17p deletion, stem cell transplantation must be considered.

Background: Most peripheral T-cell lymphoma (PTCL) patients have a poor outcome and the identification of prognostic factors at diagnosis is needed. Patients and methods: The prognostic impact of total metabolic tumor volume (TMTV0), measured on baseline [18F] <br />2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography, was evaluated in a retrospective study including 108 PTCL patients (27 PTCL not otherwise specified, 43 angioimmunoblastic T-cell lymphomas and 38 anaplastic large-cell lymphomas). All received anthracycline-based chemotherapy. TMTV0 was computed with the 41% maximum standardized uptake value threshold method and an optimal cut-off point for binary outcomes was determined and compared with others prognostic factors. <br />Results: With a median follow-up of 23 months, 2-year progression-free survival (PFS) was 49% and 2-year overall survival (OS) was 67%. High TMTV0 was significantly associated with a worse prognosis. At 2 years, PFS was 26% in patients with a high TMTV0 (>230 cm3, n = 53) versus 71% for those with a low TMTV0, [P < 0.0001, hazard ratio (HR) = 4], whereas OS was 50% versus 80%, respectively, (P = 0.0005, HR = 3.1). In multivariate analysis, TMTV0 was the only significant independent parameter for both PFS and OS. TMTV0, combined with PIT, discriminated even better than TMTV0 alone, patients with an adverse outcome (TMTV0 >230 cm3 and PIT >1, n = 33,) from those with good prognosis (TMTV0 ≤230 cm3 and PIT ≤1, <br />n = 40): 19% versus 73% 2-year PFS (P < 0.0001) and 43% versus 81% 2-year OS, respectively (P = 0.0002). Thirty-one patients (other TMTV0–PIT combinations) had an intermediate outcome, 50% 2-year PFS and 68% 2-year OS. <br />Conclusion: TMTV0 appears as an independent predictor of PTCL outcome. Combined with PIT, it could identify different risk categories at diagnosis and warrants further validation as a prognostic marker. [less ▲]

Primary bone diffuse large B-cell lymphoma (PB-DLBCL) is a rare DLBCL location variant. We treated 76 PB-DLBCL patients by immuno-chemotherapy, resulting in an 84% sustained complete remission rate and a 78.9% survival over a 4.7-year median follow-up period. Ann Arbor stage IV and high age-adjusted international prognostic index were predictive of adverse outcome in univariate analysis. In multivariate analysis using a Cox model, only aa-IPI predicted long-term survival. While based on a limited number of cases, we suggested that radiotherapy may be useful as a consolidation modality in PB-DLBCL. We also suggested that positron emission tomography/CT scan should be interpreted with caution due to a persistent [18F]fluorodeoxyglucose [18FDG] uptake of bone lesions even after remission in some in PB-DLBCL patients. Our study based on a homogeneous cohort of PB-DLBCL patients confirmed the favorable outcome of this DLBCL variant and support the implementation of prospective clinical trials in this disease.

Waldenström’s macroglobulinaemia is a B-cell disorder characterised by bone marrow infiltration with lymphoplasmacytic cells, along with demonstration of an IgM monoclonal gammopathy in the blood. This condition belongs to the lymphoplasmacytic lymphomas as defined by the World Health Organization classification (ICD-0 code 9671/3). Approximately one-fourth of patients are asymptomatic. Clinical features of the symptomatic patients are diverse and may relate to overall disease burden (such as peripheral blood cytopaenias, organomegaly and constitutional symptoms) or may be directly attributable to the IgM paraprotein. The latter include hyperviscosity syndrome, amyloidosis, peripheral neuropathy and cold haemagglutinin. Therapeutic options have traditionally involved alkylating agents, nucleoside analogues, and rituximab, either as single therapy or in combination. However, emerging new data on combination therapy as well as novel agents have shown encouraging results. This report provides the Belgian Hematology Society guidelines according to recent clinical studies. [less ▲]

We present a patient with Burkitt's lymphoma who suffered a severe haemolytic crisis after treatment with rasburicase. This case report underlines the high incidence of glucose-6-phosphate dehydrogenase deficiency in some ethnic groups and the importance of a detailed patient and family history before starting treatment, even in case of emergency. Glucose-6-phosphate dehydrogenase is an essential enzyme since it makes the synthesis of NADPH + H from NADP possible, which determines the reducing power (NADPH) of the cell. Every defect in this physiological process, notably glucose-6-phosphate dehydrogenase deficiency, may thus result simultaneously with the use of rasburicase in acute or chronic haemolysis according to the importance of the deficiency. Management is based on stopping the incriminated drug and on supportive therapy consisting of administering packed red blood cells if the anaemia is poorly tolerated. [less ▲]

Burkitt lymphoma (BL) is a rare but very aggressive non-Hodgkin’s lymphoma characterized by an isolated translocation t(8;14)(q24;q32). The sporadic form is the subentity most frequently encountered in our country. Diagnosis and initial work-up must be completed rapidly to start treatment as soon as possible. Positron emission tomography (PET) scan is useful for initial staging and to evaluate the chemosensitivity of the tumor during and after treatment. After debulking, it is recommended to add rituximab to chemotherapy. Currently intensive short-cycle chemotherapies (ISCC) and low intensity chemotherapies (LIC) are two valuable options. Radiotherapy is not indicated except in case of central nervous system involvement. Patients achieving complete remission must be followed carefully during the first year to detect recurrence of the disease. More than 80% of patients sustain their remission one year following initial treatment and are considered cured. For patients in partial remission or with chemosensitive relapse, autologous stem cell transplantation is recommended following re-induction with non-cross-resistant polychemotherapy. Monitoring complete blood counts and cognitive functions is important to detect late toxicity of the applied therapies. [less ▲]

Mantle cell lymphoma was recognised in the nineties and is characterised by the t(11;14)(q13;q32) translocation which results in overexpression of cyclin D1.1 This disease represents approximately 6% of all non-Hodgkin's lymphomas. Mantle cell lymphoma generally affects patients over 60 years-old. Most patients have advanced disease (>70 % Ann Arbor stage IV). Several efforts have been made to predict outcome in mantle cell lymphoma. The cell-proliferation marker Ki-67, the Mantle Cell Lymphoma International Prognostic Index, fluorodeoxyglucose positron emission tomography and minimal residual disease are prognostic tools. For young patients, chemoimmunotherapy followed by high-dose chemotherapy plus stem cell transplantation is the treatment of choice. For the main group of older patients, chemo-immunotherapy followed by maintenance with rituximab is the gold standard. In relapses, temsirolimus is actually registered and new drugs, such as ibrutinib, are currently evaluated with promising preliminary results.2 [less ▲]
