Skeletal survey (SS) continues to be used in the community to detect bone disease in patients with multiple myeloma (MM). While the false-negative rate is high, the specificity of SS is less well characterised. Here, we compare the diagnostic accuracy of SS compared to 18 F-FDG-PET/CT (positron emission tomography/computed tomography) in 79 patients referred to our tertiary centre with a diagnosis of smouldering MM. SS had a specificity of 83·1% (95% confidence interval: 72·0-90·5%). This study reinforces the importance of using more specific imaging techniques to avoid inaccurate diagnosis that could lead to the risks associated with unnecessary therapy in patients with smouldering MM...

The diagnosis of juvenile myelomonocytic leukaemia (JMML) is based on clinical, laboratory and molecular features but immunophenotyping [multiparametric flow cytometry (MFC)] has not been used routinely. In the present study, we describe the flow cytometric features at diagnosis with special attention to the distribution of monocytic subsets and the relation between MFC and molecular subgroups. MFC was performed with an eight-colour platform based on Euroflow. We studied 33 JMML cases. CD34+ /CD117+ /CD13+ cells >2% was found in 25 cases, and 51·5% presented an aberrant expression of CD7...

Burkitt lymphoma (BL) is an aggressive B-cell-malignancy derived from germinal-centre B-cells. Curative therapy traditionally requires intensive immunochemotherapy. Recently, immuno-oncological approaches, modulating the T-cell tumour response, were approved for the treatment of a variety of malignancies. The architecture of the tumour-infiltrating T-cell receptor (TCR) repertoire in BL remains insufficiently characterized. We therefore performed a large-scale, next-generation sequencing study of the complimentary-determining region (CDR)-3 region of the TCRβ chain repertoire in a large cohort of all epidemiological subtypes of BL (n = 82) and diffuse large B-cell lymphoma (DLBCL; n = 34)...

Panobinostat is a pan-deacetylase inhibitor that modulates the expression of oncogenic and immune-mediating genes involved in tumour cell growth and survival. We evaluated panobinostat-induced post-transplant responses and identified correlative biomarkers in patients with multiple myeloma who had failed to achieve a complete response after autologous transplantation. Patients received panobinostat 45 mg administered three-times weekly (TIW) on alternate weeks of 28-day cycles commencing 8-12 weeks post-transplant...

Genetic studies in patients with Philadelphia-negative myeloproliferative neoplasms (MPNs) are essential to establish the correct diagnosis and to optimise their management. Recently, it has been demonstrated that it is possible to detect molecular alterations analysing cell-free DNA (cfDNA) in plasma samples, which is known as liquid biopsy. We have assessed the molecular profile of a cohort of 107 MPN patients [33 polycythaemia vera (PV), 56 essential thrombocythaemia (ET), 14 primary myelofibrosis (PMF) and 4 unclassifiable MPN] by next-generation sequencing (NGS) using cfDNA and paired granulocyte DNA...

This cohort study of the International Network on Cancer, Infertility and Pregnancy (INCIP) reports the maternal and neonatal outcomes of 80 pregnant patients diagnosed with non-Hodgkin lymphoma (NHL) between 1986 and 2019, focussing on 57 (71%) patients with diffuse large B-cell lymphoma (DLBCL). Of all 80 patients, 54 (68%) pregnant patients received chemotherapy; mostly (89%) CHOP-like (cyclophosphamide, doxorubicin, vincristine, and prednisone) regimens. Four early pregnancies were terminated. Among 76 ongoing pregnancies, there was one stillbirth (1·3%)...

Patients with an ABL-class fusion have a high risk of relapse on standard chemotherapy but are sensitive to tyrosine kinase inhibitors (TKI). In UKALL2011, we screened patients with post-induction MRD ≥1% and positive patients (12%) received adjuvant TKI. As the intervention started during UKALL2011, not all eligible patients were screened prospectively. Retrospective screening of eligible patients allowed the outcome of equivalent ABL-class patients who did and did not receive a TKI in first remission to be compared...

Standard treatment for classical Hodgkin lymphoma (cHL) is poorly tolerated in older patients and results disappointing. We assessed safety and efficacy of brentuximab vedotin (BV), in previously untreated patients with cHL unfit for standard treatment due to age, frailty or comorbidity. The primary outcome was complete metabolic response (CMR) by positron emission tomography/computed tomography after four BV cycles (PET4). The secondary outcomes included progression-free survival (PFS), overall survival (OS), and toxicity...

Burkitt lymphoma (BL) accounts for almost two-thirds of all B-cell non-Hodgkin lymphoma (B-NHL) in children and adolescents and is characterised by a MYC translocation and rapid cell turnover. Intensive chemotherapeutic regimens have been developed in recent decades, including the lymphomes malins B (LMB) protocol, which have resulted in a survival rate in excess of 90%. Recent clinical trials have focused on immunochemotherapy, with the addition of rituximab to chemotherapeutic backbones, showing encouraging results...

Spontaneous abortion is a common, detrimental outcome of pregnancy, and can be induced by a variety of factors, including pathophysiological conditions and socioeconomic circumstances. Despite numerous studies examining the aetiology of spontaneous abortion, there is limited understanding of the disordered iron transportation between mother and fetus through the placenta. Recently, erythroferrone (ERFE) was recognized as a novel negative regulator of hepcidin that can elevate nutritional iron absorption and macrophagic iron egress for enhanced erythropoiesis...
