RESUMO
The use of immunochemotherapy has improved the outcome of follicular lymphoma (FL). Recently, complete response at 30 months (CR30) has been suggested as a surrogate for progression-free survival. This study aimed to analyse the life expectancy of FL patients according to their status at 30 months from the start of treatment in comparison with the sex and age-matched Spanish general population (relative survival; RS). The training series comprised 263 patients consecutively diagnosed with FL in a 10-year period who needed therapy and were treated with rituximab-containing regimens. An independent cohort of 693 FL patients from the Grupo Español de Linfomas y Trasplante Autólogo de Médula Ósea (GELTAMO) group was used for validation. In the training cohort, 188 patients were in CR30, with a 10-year overall survival (OS) of 53% and 87% for non-CR30 and CR30 patients, respectively. Ten-year RS was 73% and 100%, showing no decrease in life expectancy for CR30 patients. Multivariate analysis indicated that the FL International Prognostic Index was the most important variable predicting OS in the CR30 group. The impact of CR30 status on RS was validated in the independent GELTAMO series. In conclusion, FL patients treated with immunochemotherapy who were in CR at 30 months showed similar survival to a sex- and age-matched Spanish general population.

The availability of new agents for the treatment of multiple myeloma has allowed the use of multiple lines of treatment, but a percentage of patients do not reach to receive this combination because of toxicity and early death. In this regard, a cross-sectional European study evaluated the management of different lines and discontinuation of treatment in 7635 patients from seven countries in routine clinical practice, finding that 39% of European patients do not receive a second line and that only 4% of patients reach third line in Spain, a figure that is striking when comparing with the rest of the countries. We analyze the frequency and causes of treatment discontinuation in a series of 108 patients from a Spanish University hospital showing that the main reason for permanent treatment discontinuation after finishing first line was to have a response, while death due to disease progression accounted for the main reason in subsequent lines of therapy, with its frequency increasing according to the number of lines received. Additionally, in our longitudinal study, we estimated, using a competitive risk analysis, that 22% of patients would not receive a second line of therapy at 60 months and 47% would not reach third line, also at 60 months, showing a marked discrepancy with the results reported in the cross-sectional European study. Although based on limited data, our results suggest the convenience of validating the findings of cross-sectional studies conducted in large cohorts.

OBJECTIVE: To evaluate the role of N-terminal pro-brain-type natriuretic peptide (NT-proBNP) and a cardiovascular (CV) risk score named FRESCO for predicting anthracycline-induced cardiotoxicity (AIC) in diffuse large B-cell lymphoma (DLBCL). METHODS: A total of 130 consecutive DLBCL patients treated in first-line with anthracycline-containing immunochemotherapy. Competitive risk between NT-proBNP, FRESCO, and time to AIC was considered. RESULTS: Cumulative incidence of AIC was 12.2% and 17.5% at 1 and 5 years, respectively. Median time to development cardiotoxicity was 6.4 months, with half of the cases showing heart failure and the other half silent AIC. Both NT-proBNP levels and FRESCO score were independently associated with higher risk of AIC (P = 0.001 and P = 0.03, respectively). Patients with NT-proBNP ≥600 pg/mL or those with FRESCO ≥4.5% had 3.97 or 2.54 times higher risk of AIC than those with lower values (P = 0.001 and P = 0.048, respectively). According to the previous cutoffs, three groups of patients with a significantly different risk of AIC could be identified (P < 0.0001). CONCLUSIONS: Doxorubicin-containing chemotherapy is associated with increased risk of silent and overt AIC. Baseline NT-proBNP levels and FRESCO CV risk score are accurate predictors of AIC and can identify groups of patients at different risk, in which personalized cardiologic evaluation should be offered.

Patient and physician agreement on the most significant symptoms is associated with treatment outcomes and satisfaction with care. Thus, we sought to assess patient and physician agreement on patient-reported quality of life (QoL), and whether patient-related variables predict disagreement. In this cross-sectional, multisite study, patients and physicians completed the FACT-BMT at day 90. Agreement was analyzed with the intraclass coefficient correlation (ICC). Rates of underestimation and overestimation were calculated. Logistic regression models identified predictors of disagreement. We analyzed 96 pairs of questionnaires completed by 96 patients and 11 physicians. The patients' median age was 54 years, 52% were men, and 52% had undergone allogeneic hematopoietic cell transplantation (HCT). The physicians' median age was 42, 64% were men, and they had worked in the HCT field for an average of 12 years. Agreement on QoL was moderate (ICC = .436). Exploratory analyses revealed poor agreement for emotional (ICC = .092) and social (ICC = .270) well-being and moderate agreement for physical (ICC = .457), functional (ICC = .451), and BMT concerns (ICC = .445). Patients' well-being was underestimated by physicians in 41% to 59% of the categories of well-being parameters, and overestimated in 10% to 24%. Patient's anxiety predicted less disagreement in all scales except in social well-being, for which nonsignificant associations were observed. Patient-related variables explained 12% to 19% of the variance in disagreement across well-being scales. Patient and physician agreement on QoL was suboptimal, particularly in emotional and social well-being. The implementation of patient-reported outcomes in the daily care of HCT recipients may contribute to improving patient-centered care.

The diagnostic criteria for follicular lymphoma (FL) transformation vary among the largest series, which commonly exclude histologically-documented transformation (HT) mandatorily. The aims of this retrospective observational multicentre study by the Spanish Grupo Español de Linfoma y Transplante Autólogo de Médula Ósea, which recruited 1734 patients (800 males/934 females; median age 59 years), diagnosed with FL grades 1-3A, were, (i) the cumulative incidence of HT (CI-HT); (ii) risk factors associated with HT; and (iii) the role of treatment and response on survival following transformation (SFT). With a median follow-up of 6·2 years, 106 patients developed HT. Ten-year CI-HT was 8%. Considering these 106 patients who developed HT, median time to transformation was 2·5 years. High-risk FL International Prognostic Index [Hazard ratio (HR) 2·6, 95% confidence interval (CI): 1·5-4·5] and non-response to first-line therapy (HR 2·9, 95% CI: 1·3-6·8) were associated with HT. Seventy out of the 106 patients died (5-year SFT, 26%). Response to HT first-line therapy (HR 5·3, 95% CI: 2·4-12·0), autologous stem cell transplantation (HR 3·9, 95% CI: 1·5-10·1), and revised International Prognostic Index (HR 2·2, 95% CI: 1·1-4·2) were significantly associated with SFT. Response to treatment and HT were the variables most significantly associated with survival in the rituximab era. Better therapies are needed to improve response. Inclusion of HT in clinical trials with new agents is mandatory.

Masked polycythaemia vera (PV) has been proposed as a new entity with poorer outcome than overt PV. In this study, the initial clinical and laboratory characteristics, response to treatment and outcome of masked and overt PV were compared using red cell mass and haemoglobin or haematocrit levels for the distinction between both entities. Sixty-eight of 151 PV patients (45%) were classified as masked PV according to World Health Organisation diagnostic criteria, whereas 16 (11%) were classified as masked PV using the British Committee for Standards in Haematology (BCSH). In comparison with overt PV, a higher platelet count and a lower JAK2V617F allele burden at diagnosis were observed in masked PV. Patients with masked PV needed lower phlebotomies and responded faster to hydroxcarbamide than those with overt PV. Complete haematological response was more frequently achieved in masked than in overt PV (79% vs. 58%, P = 0.001). There were no significant differences in the duration of haematological response, the rate of resistance or intolerance to hydroxycarbamide and the probability of molecular response according to type of PV (masked vs. overt). Overall survival, rate of thrombosis and major bleeding, and probability of transformation was superimposable among patients with masked and overt PV.

Low serum erythropoietin (EPO) is a minor criterion of Polycythaemia Vera (PV) but its diagnostic usefulness relies on studies performed before the discovery of JAK2 V617F mutation. The objective of the present study was to evaluate the diagnostic accuracy of serum EPO and JAK2 V617F allele burden as markers of PV as well as the combination of different diagnostic criteria in 287 patients (99 with PV, 137 with Essential Thrombocythaemia and 51 with non-clonal erythrocytosis). Low EPO showed good diagnostic accuracy as a marker for PV, with the area under the curve (AUC) of the chemiluminescent-enhanced enzyme immunoassay (CEIA) being better than that of radioimmunoassay (RIA) (0·87 and 0·76 for CEIA and RIA, respectively). JAK2 V617F quantification displayed an excellent diagnostic accuracy, with an AUC of 0·95. A haematocrit >52% (males) or >48% (females) plus the presence of the JAK2 V617F mutation had a sensitivity and specificity of 79% and 97%, respectively. Adding low EPO or the JAK2 V617F allele burden did not improve the diagnostic accuracy for PV whereas the inclusion of both improved the sensitivity up to 83% and maintaining 96% specificity. Haematocrit and qualitative JAK2 V617F mutation allow a reliable diagnosis of PV. Incorporation of EPO and/or JAK2 V617F mutant load does not improve the diagnostic accuracy.

Bone marrow histology is included in the diagnostic criteria of myeloproliferative neoplasms (MPNs). However, some concerns have emerged about its reproducibility. To evaluate the diagnostic accuracy of histology and to assess its correlation with presence of mutations and clinical outcomes, two pathologists reviewed the bone marrow biopsies corresponding to 211 patients with MPN. Despite the low agreement in the evaluation of individual histopathological characteristics, the concordance among pathologists when establishing the diagnosis was good (Kappa index 0·67). The specificity of histology was 100%, 98·5% and 98% in polycythaemia vera (PV), essential thrombocythaemia (ET) and primary myelofibrosis (PMF), respectively, whereas the sensitivity of histological diagnosis was low in PV and ET (32·5% and 54% respectively) and acceptable in PMF (75%). Thirteen out of 146 (9%) patients with clinical ET were diagnosed as prefibrotic PMF. No histological agreement or MPN otherwise unspecified was more frequently observed in JAK2 V617F-positive ET than in CALR-mutated cases, whereas megakaryocytic abnormalities and prefibrotic PMF were more frequently observed in CALR-mutated ET. In conclusion, histological criteria of MPN have a limited diagnostic accuracy due to low sensitivity. Patients with JAK2 V617F-positive MPN have a heterogeneous histology while CALR-positive ET is associated with megakaryocyte abnormalities and prefibrotic PMF.

INTRODUCTION: Immune thrombocytopenia (ITP) is a potentially severe manifestation of systemic lupus erythematosus (SLE) reported in 7-40% of SLE patients. ITP has been associated with a higher risk of organ damage and mortality. OBJECTIVES: To describe which factors are associated with the presence of ITP in SLE patients. METHODS: Retrospective case-control study. Cases were defined as SLE patients who had ever developed ITP and were sex- and age-matched with two controls. A predictive model was constructed to identify SLE patients who were at risk of developing ITP. RESULTS: ITP prevalence in our SLE cohort was 8.35%. Cases had a higher frequency of hemolytic anemia, while controls had a higher prevalence of arthritis at SLE diagnosis. During SLE progression, cases tested positive for anticardiolipin, anti-ß2-glycoprotein 1, and lupus anticoagulant antibodies more frequently. Cases received mycophenolic acid and azathioprine more often than controls and had a higher SLICC/ACR score. The model demonstrated a sensitivity of 87.53%, a positive predictive value of 81.92%, a specificity of 80.50%, area under the curve of 83.92%, a F1 of 83% and an overall accuracy of 83.68%. The variables that best explain the model were hemolytic anemia, arthritis, oral ulcers, Raynaud's phenomenon, low C4, low CH50, anticardiolipin and anti-ß2GP1 antibodies. CONCLUSION: SLE patients who develop ITP have a distinct phenotype characterized by more hemolytic anemia and less arthritis at SLE onset, and higher prevalence of antiphospholipid syndrome antibodies during SLE progression. This phenotype is associated with heightened organ damage and the need for more intensive therapies and stricter follow-up. Our predictive model has demonstrated an impressive ability to identify SLE patients at risk of developing ITP.

The cut off for hemoglobin or hematocrit that indicates the need for an isotopic red cell mass study was investigated in 179 patients with a presumptive diagnosis of polycythemia vera or essential thrombocythemia. Hematocrit showed better diagnostic accuracy than hemoglobin. Hemoglobin over 18.5 g/dL in males or over 16.5 g/dL in females showed a high specificity indicating that red cell mass study could be avoided in such cases, but it showed low sensitivity leading to 46% false negatives. The best value of hematocrit to indicate a red cell mass study was 0.50 L/L in males (specificity 75%, sensitivity 87.5%) and 0.48 L/L in females (specificity 73%, sensitivity 94%). Lowering the hematocrit threshold to 0.48 L/L in males increased sensitivity up to 95%. A red cell mass study should be performed in patients with suspected diagnosis of essential thrombocythemia or polycythemia vera and with hematocrit between 0.48 L/L and 0.52 L/L.

SARS-CoV-2 vaccination is the most effective strategy to protect individuals with haematologic malignancies against severe COVID-19, while eliciting limited vaccine responses. We characterized the humoral responses following 3 mo after mRNA-based vaccines in individuals at different plasma-cell disease stages: monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and multiple myeloma on first-line therapy (MM), compared with a healthy population. Plasma samples from uninfected MM patients showed lower SARS-CoV-2-specific antibody levels and neutralization capacity compared with MGUS, SMM, and healthy individuals. Importantly, COVID-19 recovered MM individuals presented significantly higher plasma neutralization capacity compared with their uninfected counterparts, highlighting that hybrid immunity elicit stronger immunity even in this immunocompromised population. No differences in the vaccine-induced humoral responses were observed between uninfected MGUS, SMM and healthy individuals. In conclusion, MGUS and SMM patients could be SARS-CoV-2 vaccinated following the vaccine recommendations for the general population, whereas a tailored monitoring of the vaccine-induced immune responses should be considered in uninfected MM patients.

Hodgkin lymphoma (HL) is a highly-curable malignancy mostly affecting young people. As far as we know, there is no published study that has analyzed personality profiles in HL nor their potential role in lymphomagenesis, natural history, or response to treatment. We aim to explore the personality traits of HL patients, as well as the prevalence of mental disorders and suicide ideas. We retrospectively identified all alive HL patients from three centers (Son Espases and Son Llatzer University Hospitals and Hospital del Mar of Barcelona) for using NEO Five-Factor Inventory (NEO-FFI) and Personality Inventory for DSM-5 Brief Form. Patients with HL showed significantly higher neuroticism scores and lower conscientiousness, extraversion, and openness. Considering maladaptive personality traits, HL patients showed higher levels of detachment and psychoticism. All of these translated into the fact that HL patients showed more than double the prevalence of mental illnesses (41%) and more than triple the prevalence of suicidal ideation or attempts than the general population (15 and 6%, respectively). An exploratory analysis of biomarkers associated with HL personality traits showed that higher scores of neuroticism correlated with more elevated erythrocyte sedimentation rate (ESR) and red cell distribution width (RDW), suggesting a potential link between neuroticism and proinflammatory activity in HL.
RESUMO
OBJECTIVE: Our aim was to retrospectively assess the role of routine CT scans within the first year of follow-up with a limited surveillance policy prior to Lugano recommendations in diffuse large B-cell lymphomas (DLBCL) achieving complete metabolic remission (CMR). We also evaluated the type of relapse detection and exposure to CT scans within the first five years. METHODS: Patients diagnosed with DLBCL who achieved CMR after first-line immunochemotherapy were included. Imaging studies and medical records were thoroughly reviewed. RESULTS: Among 101 DLBCL patients in the first CMR, a total of 19 relapses were identified in the study period (18.8% of DLBCL patients included). Nine patients relapsed within the first year (47.4% of all relapses) but only 3 of them were detected by the 202 surveillance CT scans performed during this first year of follow-up. CONCLUSIONS: Our real-world data provide clinically applicable results which are in agreement with the Lugano recommendations based on trial data, highlighting the lack of utility of routine CTs in DLBCL patients achieving CMR.

BACKGROUND AND OBJECTIVE: The optimal treatment of aggressive non-Hodgkin lymphoma (NHL) in elderly patients remains controversial. We aimed to evaluate the impact of age and use of anthracyclines. PATIENTS AND METHOD: Retrospective analysis of patients with aggressive NHL aged over 70 years old. RESULTS: One hundred and twenty-eight patients with a median age of 76 years (70-91). Eighty-eight percent received chemotherapy, and 72% received anthracyclines. The overall response rate was 70%, 51% with a complete response (CR)/uncertain complete response and 19% with a partial response (PR). Overall survival (OS) was 28 months (95% confidence interval 18-78). In the diffuse large B-cell lymphoma group, progression-free survival (PFS) and OS were significantly better in patients who achieved CR versus PR. The use of anthracyclines was associated with CR, the international prognostic index (IPI) was associated with both survival and response, and age showed no association. CONCLUSIONS: In patients aged ≥ 70 years with aggressive lymphoma who received chemotherapy, the IPI but not age and the use of anthracyclines showed a prognostic impact. Therefore, in elderly patients with aggressive lymphomas, the use of anthracyclines should be considered and therapeutic decisions should not be based on age exclusively.

BACKGROUND AND OBJECTIVE: Two prognostic models to predict overall survival and thrombosis-free survival have been proposed: International Prognostic Score for Essential Thrombocythemia (IPSET) and IPSET-Thrombosis, respectively, based on age, leukocytes count, history of previous thrombosis, the presence of cardiovascular risk factors and the JAK2 mutational status. The aim of the present study was to assess the clinical and biological characteristics at diagnosis and during evolution in essential thrombocythemia (ET) patients as well as the factors associated with survival and thrombosis and the usefulness of these new prognostic models. PATIENTS AND METHODS: We have evaluated the clinical data and the mutation status of JAK2, MPL and calreticulin of 214 ET patients diagnosed in a single center between 1985 and 2012, classified according to classical risk stratification, IPSET and IPSET-Thrombosis. RESULTS: With a median follow-up of 6.9 years, overall survival was not associated with any variable by multivariate analysis. Thrombotic history and leukocytes>10×10(9)/l were associated with thrombosis-free survival (TFS). In our series, IPSET prognostic systems of survival and thrombosis did not provide more clinically relevant information regarding the classic risk of thrombosis stratification. CONCLUSION: Thrombotic history and leukocytosis>10×10(9)/l were significantly associated with lower TFS, while the prognostic IPSET-Thrombosis system did not provide more information than classical thrombotic risk assessment.

Doxorubicin-containing chemotherapy is the standard regimen for elderly patients with aggressive lymphoma. However, many of them cannot receive it due to severe associated comorbidities. Toxicity and efficacy of intermediate doses of nonpegylated liposomal doxorubicin (NPLD) in modified-CHOP regimen ± Rituximab were prospectively analyzed in 35 frail elderly patients (median age: 76 years) with previously untreated aggressive lymphoma with one or more severe comorbidities. NPLD at intermediate doses (30mg/m(2)) is effective and well tolerated in these patients. In addition, NT-proBNP levels > 900ng/ml at diagnosis have demonstrated to be a good predictor for OS and PFS in this cohort of patients.

NT-proBNP provides diagnostic and prognostic information in heart syndromes but its role in cancer has not yet been established. The prognostic value of NT-proBNP was prospectively studied in 104 non-Hodgkin lymphoma (NHL) patients treated with chemotherapy. Echocardiography and NT-proBNP were determined prior to treatment. In multivariate analysis, NT-proBNP ≥ 900 pg/ml was the variable with higher risk of death (adjusted hazard ratio 11.1; 95% CI 3.8-32.9; P<0.001). The C statistic for NT-proBNP ≥ 900 pg/ml was significantly better than IPI score for prediction of survival. These findings suggest that NT-proBNP ≥ 900 pg/ml could be considered a useful marker for risk assessment in NHL patients treated with chemotherapy.
