Graft-versus-host disease (GvHD) is a major complication of allogeneic stem cell transplantation. High-resolution in vivo histology of the intestine by confocal endomicroscopy (CEM) detects acute GvHD (aGvHD) with high sensitivity. This pilot study aims to evaluate the diagnostic value of CEM for intestinal chronic GvHD (cGvHD). The study included 20 patients with gastrointestinal symptoms and confirmed cGvHD in other organs as well as 20 patients with clinically suspected acute GvHD for control. Confocal endomicroscopy was performed as gastroscopy followed by sigmoidoscopy after intravenous injection of fluorescein (10%) and topical application of acriflavine (0...

The purpose of this phase 2, multicenter study was to determine the activity and safety of nonpegylated liposomal doxorubicin as part of "R-COMP" combination in patients with diffuse large B-cell lymphoma and coexisting cardiac disorders. The study was conducted using a Bayesian continuing assessment method using complete remission rate and rate of cardiac events as study endpoints. Between November 2009 and October 2011, 50 evaluable patients were enrolled (median age, 76 years). Median baseline left ventricular ejection fraction (LVEF) was 60%...

Patients with myelofibrosis at intermediate-1 risk according to the International Prognostic Score System are projected to a relatively long survival; nonetheless, they may carry significant splenomegaly and/or systemic constitutional symptoms that hamper quality of life and require treatment. Since registrative COMFORT studies included only patients at intermediate-2/high International Prognostic Score System risk, safety and efficacy data in intermediate-1 patients are limited. We report on 70 intermediate-1 patients treated with ruxolitinib according to standard clinical practice that were evaluated for response using the 2013 IWG-MRT criteria...

An accurate histological diagnosis may distinguish essential thrombocythaemia (ET) from early primary myelofibrosis (early-PMF), which is associated with worse outcome. Outcome of ET is also negatively affected by the presence of the JAK2(V617F) mutation. To investigate the impact of JAK2(V617F) mutation burden and histology on outcome, we collected 475 WHO-diagnosed ET (69.2%) or early-PMF JAK2(V617F) -positive patients followed in 4 Italian haematology centers. JAK2(V617F) allele burden was ≤50% in 90% and 87% of ET and early-PMF patients, respectively (P = ...

Delayed platelet recovery (DPR) despite prompt neutrophil engraftment is frequently observed after allogeneic hematopoietic stem cell transplantation (HSCT). However, few studies have evaluated the risk factors and long-term outcome. Therefore, we retrospectively analysed 219 adult patients who underwent their first allogenic HSCT with neutrophil engraftment. Of these 219 patients, 50 (22.8%) had DPR that was defined as relapse-free survival at day 60 after HSCT without primary platelet recovery despite neutrophil engraftment...

Comorbidity impacts survival in B-cell lymphoma patients, but the influence in peripheral T-cell lymphomas (PTCLs) has been little studied. To investigate the impact of comorbidity on outcome in PTCL, we identified adult patients with newly diagnosed PTCL from 2000 to 2009 in the Swedish Lymphoma Registry. Data on comorbidity at diagnosis were retrospectively collected according to the Charlson Comorbidity Index (CCI). Comorbid conditions were present in 263 out of 694 (38%) patients. A CCI score of ≥2 was associated with inferior overall survival (OS) (hazard ratio [HR] 1...

Claudio Fozza
The clinical history of patients with myelodysplastic syndromes (MDS) is characterised by bone marrow insufficiency as well as by the possible evolution into acute leukaemia. However a number of reports highlight the frequent occurrence of autoimmune manifestations involving different sites and organs. The present review will first describe the clinical pictures most often observed in MDS patients. The actual burden of autoimmunity will be then addressed by focusing on the few available registry studies. Finally, the potential collateral impact of specific treatments for MDS on the evolution of autoimmune disorders will be considered...

Studies that have evaluated the prognostic value of body mass index (BMI) in patients with diffuse large B-cell lymphoma have recently been reported. However, the impact of BMI on survival outcomes remains controversial. We retrospectively analyzed the data of 406 diffuse large B-cell lymphoma patients treated with R-CHOP or R-CHOP-like regimens. The number (%) of patients that were categorized into 1 of 4 groups according to BMI were underweight (<18.5 kg/m(2) ), 58 (14.3%); normal weight (≥18.5 to <25 kg/m(2) ), 262 (64...

Discrimination between lymphoid blast crisis of chronic myeloid leukemia (CML) and de novo BCR-ABL1 positive acute lymphoblastic leukemia (ALL) represents a diagnostic challenge because this distinction has a major incidence on the management of patients. Here, we report an uncommon pediatric case of ALL with cryptic ins(22;9)(q11;q34q34) and p190-type BCR-ABL1 transcript. We performed interphase fluorescence in situ hybridization (FISH) for BCR-ABL1 rearrangement on blood neutrophils, which was positive consistent with the diagnosis of lymphoid blast crisis of CML...

Age is a well-known factor in solid tumours linked to lower adherence to guidelines. Scarce data exist for haematologic malignancies such as multiple myeloma (MM). The aim of the study was to investigate the relationships among age, adherence to guidelines in MM, and overall survival (OS).The Poitou-Charentes cancer registry has exhaustively registered incident cases of MM from 2008 to 2010. Diagnosis, staging, prognosis, and first-line treatment were compared to the international guidelines. Three hundred and sixty-seven patients aged 36 to 93 years were included...

Although clinical use of positron emission tomography-computed tomography (PET-CT) scans is well established in aggressive lymphomas, its prognostic value in marginal zone lymphoma (MZL) remains yet unclear. Hence, we investigated potential role of PET-CT in predicting MZL patients' outcomes following systemic chemotherapy. A total of 32 patients with MZL who received first-line chemotherapy were included in the analysis. They all underwent pretreatment, interim, and posttreatment PET-CT scans. The primary objective was to evaluate the role of complete metabolic response (CMR) in posttreatment PET-CT scans in predicting progression-free survival (PFS)...

Castleman disease is a rare lymphoproliferative disorder with 2 distinctly defined clinical forms. While multicentric Castleman disease (UCD) poses a potential therapeutic challenge, unicentric variant has historically been considered curable with surgical resection. Hence, little is known to guide management of patients with UCD, refractory to surgical resection and combination chemotherapy. We present a case of a patient, negative for HIV and HHV-8, who had an unsuccessful surgical intervention and no response to radiotherapy and chemotherapy...

Neuropathies associated with plasma cell dyscrasias are a major cause of morbidity for patients managed by medical oncologists. Because of similarities in clinical presentation and on nerve conduction studies, identifying the underlying disease leading to a paraproteinemic neuropathy can often be difficult. In addition, the degree of neurologic deficit does not strictly correlate with the extent of abnormalities on common clinical laboratory testing. Fortunately, with increasing understanding into the biologic mechanisms of underlying hematologic diseases, additional biomarkers have recently been developed, thus improving our diagnostic capacity...

In this single-center, population-based, and retrospective study, we analyzed the outcome of 49 patients with solitary bone plasmacytoma (SBP) and 28 patients with solitary extramedullary plasmacytoma (SEP), all treated with radiotherapy. Laminectomy was performed in 18/30 SBP patients with vertebral involvement and tumour resection in 10 SEP patients. Overall survival and cause of death for each patient were compared to 5 sex-, age-, and residency-matched individuals from the normal population. Response (complete and partial) was achieved in 94% of SBP and 96% of SEP patients...

We retrospectively investigated 144 patients with relapsed acute myeloid leukemia (AML) to clarify predisposing factors and the prognostic impact of acquisition of additional cytogenetic abnormalities (ACA) at the first relapse. Additional cytogenetic abnormalities are recognized as clonal evolution at the cytogenetic level. Fifty-nine patients (41%) acquired ACA at the first relapse. The incidences of ACA acquisition varied depending on cytogenetic abnormalities at initial diagnosis. Multivariate analysis identified t(8;21), complex karyotype, and a duration of fewer than 12 months of complete remission as independent predisposing factors for ACA acquisition...

Systemic reports on the descriptive epidemiology of non-Hodgkin lymphoma (NHL) from Southeast Asia are scarce. A nationwide multi-institutional registry was conducted to compare the histopathology, clinical features, and survival of Thai adult patients with NHL using large registries, especially those from Far East Asia (FEA). Using a web-based registry system, 13 major medical centers from the 4 geographic regions of Thailand prospectively collected, from 2007 to 2014, the diagnostic pathology, according to the World Health Organization classification, 2008, clinical features and survival of 4056 patients who were newly diagnosed with NHL...
