Symptom burden in myeloproliferative neoplasms (MPNs) is heterogeneous even among patients within the same MPN diagnosis. Using cluster analysis from prospectively gathered symptom burden data in 1470 international patients with essential thrombocythemia (ET), polycythemia vera (PV), or myelofibrosis (MF), we assessed for the presence of clusters and relationship to disease features and prognosis. In MF (4 clusters identified), clusters significantly differed by Dynamic International Prognostic Scoring System (DIPSS) risk (P < .001), leukopenia (P = .009), thrombocytopenia (P < .001), and spleen size (P = .02). Although an association existed between clusters and DIPSS risk, high symptom burden was noted in some low and intermediate-1-risk MF patients. In PV (5 clusters identified), total symptom score increased across clusters (P < .001), but clusters did not significantly differ by PV risk or the risk assessment variable of age. Among ET patients (5 clusters identified), clusters differed by gender (P = .04), anemia (P = .01), and prior hemorrhage (P = .047). Total symptom score increased across clusters (P < .001), but clusters did not significantly differ by International Prognostic Score for ET risk including the risk assessment variables. Significant symptom heterogeneity exists within each MPN subtype, sometimes independent of disease features or prognosis. © 2014 by The American Society of Hematology.

Symptomatic burden in myeloproliferative neoplasms is present in most patients and compromises quality of life. We sought to validate a broadly applicable 18-item instrument (Myeloproliferative Neoplasm Symptom Assessment Form [MPN-SAF], coadministered with the Brief Fatigue Inventory) to assess symptoms of myelofibrosis, essential thrombocythemia, and polycythemia vera among prospective cohorts in the United States, Sweden, and Italy. A total of 402 MPN-SAF surveys were administered (English [25%], Italian [46%], and Swedish [28%]) in 161 patients with essential thrombocythemia, 145 patients with polycythemia vera, and 96 patients with myelofibrosis. Responses among the 3 administered languages showed great consistency after controlling for MPN subtype. Strong correlations existed between individual items and key symptomatic elements represented on both the MPN-SAF and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30. Enrolling physicians' blinded opinion of patient symptoms (6 symptoms assessed) were highly correlated with corresponding patients'responses. Serial administration of the English MPN-SAF among 53 patients showed that most MPN-SAF items are well correlated (r > 0.5, P < .001) and highly reproducible (intraclass correlation coefficient > 0.7). The MPN-SAF is a comprehensive and reliable instrument that is available in multiple languages to evaluate symptoms associated with all types of MPNs in clinical trials globally. © 2011 by The American Society of Hematology.

Indolent nonfollicular B-cell lymphoma (INFBCL) has been classified in the World Health Organization 2008 system among the mature B-cell neoplasms and includes nodal and extranodal marginal zone lymphoma (MZL), lymphoplasmacytic lymphoma (LPL), and small lymphocytic lymphoma (SLL). Recently, the array and sequencing technologies have provided new insights into their molecular pathogenesis; the molecular discoveries, however, have not yet translated into consistent changes in their management. Thus, the therapy for INFBCL remains challenging. To promote widespread adoption of appropriate clinical practice, the Italian Society of Hematology and affiliate societies (Italian Society of Experimental Hematology and Italian Group for Bone Marrow Transplantation) reviewed the evidence regarding the management of these lymphomas to produce evidence-based recommendations aimed at contributing to therapy optimization and standardization. We used the Grades of Recommendation, Assessment, Development, and Evaluation system, which is based on a sequential assessment of the quality of evidence, followed by an analysis of the benefit/risk balance and subsequent judgment about the strength of recommendations. For issues without consistent evidence, we used the consensus technique. We have provided separate recommendations for diagnostic and staging requirements, first-line therapy, and postinduction therapy for the most frequent INFBCLs (ie, LPL, SLL, and nodal, splenic, and gastric MZL).

Background: Current treatment recommendations for patients with polycythemia vera call for maintaining a hematocrit of less than 45%, but this therapeutic strategy has not been tested in a randomized clinical trial. Methods: We randomly assigned 365 adults with JAK2-positive polycythemia vera who were being treated with phlebotomy, hydroxyurea, or both to receive either more intensive treatment (target hematocrit, <45%) (low-hematocrit group) or less intensive treatment (target hematocrit, 45 to 50%) (high-hematocrit group). The primary composite end point was the time until death from cardiovascular causes or major thrombotic events. The secondary end points were cardiovascular events, cardiovascular hospitalizations, incidence of cancer, progression to myelofibrosis, myelodysplasia or leukemic transformation, and hemorrhage. An intention-to-treat analysis was performed. Results: After a median follow-up of 31 months, the primary end point was recorded in 5 of 182 patients in the low-hematocrit group (2.7%) and 18 of 183 patients in the highhematocrit group (9.8%) (hazard ratio in the high-hematocrit group, 3.91; 95% confidence interval [CI], 1.45 to 10.53; P=0.007). The primary end point plus superficial-vein thrombosis occurred in 4.4% of patients in the low-hematocrit group, as compared with 10.9% in the high-hematocrit group (hazard ratio, 2.69; 95% CI, 1.19 to 6.12; P=0.02). Progression to myelofibrosis, myelodysplasia or leukemic transformation, and bleeding were observed in 6, 2, and 2 patients, respectively, in the low-hematocrit group, as compared with 2, 1, and 5 patients, respectively, in the high-hematocrit group. There was no significant between-group difference in the rate of adverse events. Conclusions: In patients with polycythemia vera, those with a hematocrit target of less than 45% had a significantly lower rate of cardiovascular death and major thrombosis than did those with a hematocrit target of 45 to 50%.

In a recent phase 3 trial, bortezomibmelphalan-prednisone-thalidomide followed by maintenance treatment with bortezomib-thalidomide demonstrated superior efficacy compared with bortezomib-melphalan-prednisone. To decrease neurologic toxicities, the protocol was amended and patients in both arms received once-weekly instead of the initial twice-weekly bortezomib infusions: 372 patients received once-weekly and 139 twice-weekly bortezomib. In this posthoc analysis we assessed the impact of the schedule change on clinical outcomes and safety. Long-term outcomes appeared similar: 3-year progression-free survival rate was 50% in the once-weekly and 47% in the twice-weekly group (P > .999), and 3-year overall survival rate was 88% and 89%, respectively (P = .54). The complete response rate was 30% in the onceweekly and 35% in the twice-weekly group (P = .27). Nonhematologic grade 3/4 adverse events were reported in 35% of once-weekly patients and 51% of twice-weekly patients (P = .003). The incidence of grade 3/4 peripheral neuropathy was 8% in the once-weekly and 28% in the twice-weekly group (P < .001); 5% of patients in the once-weekly and 15% in the twice-weekly group discontinued therapy because of peripheral neuropathy (P < .001). This improvement in safety did not appear to affect efficacy. This study is registered at http://www.clinicaltrials.gov as NCT01063179. © 2010 by The American Society of Hematology.

In this project, we produced drug-specific recommendations targeting the use of new agents for multiple myeloma (MM). We used the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) system which separates the judgments on quality of evidence from the judgment about strength of recommendations. We recommended thalidomide and bortezomib in MM patients candidates to autologous stem cell transplantation (ASCT) (weak positive). We did not recommend novel agents as maintenance therapy after ASCT (weak negative). In patients not candidate to ASCT, thalidomide or bortezomib (strong positive) associated with melphalan and prednisone were recommended. In these patients, no specific course of action could be recommended as for maintenance therapy. In patients who are refractory or relapsing after first-line therapy, we recommended bortezomib and pegylated liposomal doxorubicin, or lenalidomide and dexamethasone combinations (weak positive). © Springer-Verlag 2012.

Diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI) is a well-recognized entity, originally recorded as pyothorax-associated lymphoma because of the association with artificial pneumothorax. Clinically, it is characterized by a mass arising in a long-standing inflammation and by a poor prognosis. Recently, DLBCL-CI has been described growing along the wall of a preexisting cyst, without forming a mass. Here we describe a case of DLBCL-CI arising in the wall of a mature cystic teratoma of the ovary. On histology, the cystic surface of the cyst was infiltrated by large lymphocytes, immunoreacting with CD20, Multiple Myeloma Oncogene-1/Interferon Regulating Factor-4 (MUM1/IRF4), and PAX5 and positive for Epstein-Barr virus. "Cystic" DLBCL-CIs usually hold an indolent behavior despite heterogeneous therapeutic approaches. Some authors understandably wonder whether patients affected by "cystic" DLBCL-CIs are at risk for overtreatment, and, consequently, DLBCL-CIs associated with cystic lesions should be classified as an entity separated from classic pyothorax-associated lymphomas. © 2014 Elsevier Inc.

In Hodgkin Lymphoma (HL), about 20% of patients still have relapsed/refractory disease and late toxic effects rate continue to rise with time. Early FDG-PET and tissue macrophage infiltration (TAM) emerged as powerful prognostic predictors. The primary endpoint was to investigate the prognostic role of both early FDG-PET and TAM; the secondary endpoint was to test if early FDG-PET positivity could correlate with high TAM score. A cohort of 200 HL patients was analysed. Induction treatment plan consisted of two to six courses of ABVD and, if indicated, involved field radiation therapy. All patients repeated CT scan and FDG-PET after two cycles and after the completion of therapy. TAM in diagnostic specimens was determined by immunohistochemistry with a monoclonal antibody (anti-CD68 KP1). Overall, early FDG-PET was negative in 163 patients (81.5%) and positive in 37 patients (18.5%), showing a significant correlation with the achievement of CR (p<0.0001). After a median follow-up of 40months, progression free survival (PFS) was significantly better for PET negative patients (p<0.0001). CD68 expression was low, intermediate or high in 26 (13%), 100 (50%) and 74 (37%) cases, without difference in the distribution between responders and non-responders. PFS analysis showed no significant difference in any score group. TAM score did not show any correlation with early FDG-PET result. This study confirms that early FDG-PET has a high prognostic power, while TAM score does not seem to influence the outcome; in contrast to our original hypothesis, it does not correlate with FDG-PET assessment.

This study was aimed at investigating the clinical features and outcomes of follicular lymphoma (FL) patients younger than 40 years, which have not been extensively investigated yet.One hundred and fifty-five patients younger than 40 years were retrospectively studied from a series of 1002 FL patients diagnosed in four different European Oncology Centres (Barcelona, Spain; Bellinzona, Switzerland; London, UK; Novara, Italy) from 1985 to 2010.Patients younger than 40 had a lower incidence of elevated LDH, high beta2-microglobulin, and a high-risk Follicular Lymphoma International Prognostic Index (FLIPI) score, whereas bone marrow involvement and bulky and disseminated lymphadenopathy were more frequent. At a median follow-up of 10 years, younger patients, in comparison with those older than 40, had significantly better overall (OS), cause-specific survival (CSS), and progression-free survival (PFS), with 10-year OS rate of 81% versus 51% (P < 0.0001), 10-year CSS rate of 82% versus 60% (P < 0.0001), and 10-year PFS of 39% versus 24% (P = 0.0098). However, there were no significant CSS and PFS differences in comparison with the patients aged 40-60. In multivariate analysis, having the lymphoma diagnosed in the last two decades and a favourable FLIPI score were associated with a significantly longer PFS and CSS in younger patients, whereas only FLIPI retained statistical significance for OS.In our series, FL patients younger than 40 have a median OS of 24 years and their outcome seems to be improving over time. However, they still have a significantly shorter life expectancy than that of an age-matched general healthy population.

Selective depletion of B cells with the mAb rituximab may benefit the autoimmune glomerular disease idiopathic membranous nephropathy (IMN). Here, we describe our experience treating 100 consecutive IMN patients with persistent nephrotic syndrome with rituximab. We defi ned complete remission as persistent proteinuria <0.3 g/24 h and partial remission as persistent proteinuria <3 g/24 h, each also having >50% reduction in proteinuria from baseline. During a median follow-up of 29 months after rituximab administration, 65 patients achieved complete or partial remission. The median time to remission was 7.1 months. All 24 patients who had at least 4 years of follow-up achieved complete or partial remission. Rates of remission were similar between patients with or without previous immunosuppressive treatment. Four patients died and four progressed to ESRD. Measured GFR increased by a mean 13.2 (SD 19.6) ml/min per 1.73 m2 among those who achieved complete remission. Serum albumin significantly increased and albumin fractional clearance decreased among those achieving complete or partial remission. Proteinuria at baseline and the follow-up duration each independently predicted the decline of proteinuria. Furthermore, the magnitude of proteinuria reduction significantly correlated with slower GFR decline (P=0.0001). No treatment-related serious adverse events occurred. In summary, rituximab achieved disease remission and stabilized or improved renal function in a large cohort of high-risk patients with IMN. Copyright © 2012 by the American Society of Nephrology.
