Article: Risk stratification for Splenic Marginal Zone Lymphoma based on haemoglobin concentration, platelet count, high lactate dehydrogenase level and extrahilar lymphadenopathy: development and validation on 593 cases.
[show abstract] [hide abstract]
ABSTRACT: This international retrospective study of 593 Splenic Marginal Zone Lymphoma (SMZL) patients aimed to identify factors that determine treatment initiation and influence lymphoma-specific survival (LSS). Logistic regression was used to identify the factors associated with treatment. A Cox regression was used to analyse LSS in a derivation cohort of 366 patients. This produced a prognostic index (PI) and enabled the identification of three risk groups. The resulting stratification was validated in another cohort of 227 patients and compared with the Interguppo Italiano Linfomi (IIL) score in the group of 450 patients for whom all the required data were available using an extension of the net reclassification improvement. Haemoglobin concentration (Hb), extrahilar lymphadenopathy and hepatitis C virus status were associated with the initiation of treatment. Hb, platelet count, high lactate dehydrogenase level and extrahilar lymphadenopathy were independently associated with LSS. Three risk groups with significantly different five-year LSS (94%, 78% and 69%, respectively) were identified. This stratification (named HPLL on the basis of determinant factors) had a better discriminative power than the IIL score. This system is useful for stratifying SMZL patients into risk groups and may help in the selection of risk-tailored treatment approaches.British Journal of Haematology 08/2012; 159(2):164-71. · 4.94 Impact Factor -
Article: The need for improved neutropenia risk assessment in DLBCL patients receiving R-CHOP-21: findings from clinical practice.
[show abstract] [hide abstract]
ABSTRACT: Febrile neutropenia (FN) risk-assessment and granulocyte-colony stimulating factor (G-CSF) prophylaxis use in clinical practice was evaluated in patients with diffuse large B-cell lymphoma receiving R-CHOP-21. More G-CSF primary prophylaxis was used in patients assessed as high FN risk, but R-CHOP-21 was associated with substantial myelotoxicity in both high- and low-risk groups. In a multivariate analysis, older age, poor performance status, lower baseline hemoglobin, and lack of G-CSF prophylaxis were significantly associated with occurrence of FN in any cycle. Results highlight the need for improved FN risk-assessment and thorough guideline adherence to further reduce FN and better support chemotherapy delivery.Leukemia research 02/2012; 36(5):548-53. · 2.36 Impact Factor -
Article: Study of regulatory T-cells in patients with gastric malt lymphoma: influence on treatment response and outcome.
[show abstract] [hide abstract]
ABSTRACT: FOXP3+ regulatory T cells (Treg) play an essential role in modulating host responses to tumors and infections. The role of these cells in the pathogenesis of MALT lymphomas remains unknown. The aims of the study were to quantify the number of infiltrating FOXP3+ and CD3+ cells in patients with gastric MALT lymphoma at diagnosis and to study kinetics of these cells and CD20+ tumor cells after treatment and during long-term follow-up. FOXP3+, CD3+ and CD20+ cells were analyzed by immunohistochemistry and the number of cells was quantified using a micrometric ocular. Samples of 35 patients with gastric MALT lymphoma at diagnosis and after treatment were included. Diagnostic samples were compared to 19 cases of chronic gastritis and diffuse large B-cell lymphoma (DLBCL) of the stomach. The median number of FOXP3+ infiltrating cells was higher (27 cells/cm(2)) in gastric MALT patients than in DLBCL (10 cells; p = 0.162) but similar to chronic gastritis (20 cells; p = 0.605). No characteristic or specific distribution pattern of infiltrating FOXP3+ cells was found. Gastric MALT lymphoma patients responding to bacterial eradication therapy had higher number of FOXP3+ cells at study entry. Kinetics of both infiltrating FOXP3+ cells and tumor CD20+ cells were strongly dependent on the treatment administered. Gastric MALT lymphomas have a number of Treg cells more similar to chronic gastritis than to DLBCL. Patients with higher number of tumor infiltrating FOXP3+ cells at study entry seem to have better response to antibiotics. Kinetics of Treg and tumor cells are influenced by type of treatment.PLoS ONE 01/2012; 7(12):e51681. · 4.09 Impact Factor -
Article: Clinical experience of bendamustine treatment for non-Hodgkin lymphoma and chronic lymphocytic leukemia in Spain.
[show abstract] [hide abstract]
ABSTRACT: Bendamustine is a alkylating agent with a purine-like benzamidazole ring currently approved in Europe for indolent non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL) and multiple myeloma. Our aim was to analyze retrospectively the efficacy and toxicity of bendamustine in NHL and CLL in Spain in the bendamustine Compassionate Use Program. Patients with relapsed/refractory NHL or CLL were eligible. Any regimen containing bendamustine was eligible. 109 patients were included from 22 institutions. Forty-nine patients had indolent NHL, 18 aggressive NHL and 42 CLL, being 44 patients (40%) refractory to previous treatment. 63% of patients had adverse events grade 3-4, mainly hematological. Overall response rate (ORR) was 66%, complete responses 30%. ORR observed in refractory patients was 45%. The median progression-free survival (PFS) was 13 months. Outcome was influenced by histology, number of previous treatments, resistance to previous chemotherapy and type of response achieved with bendamustine. Alone or in combination, bendamustine shows a meaningful clinical antitumor activity in patients with relapsed or refractory NHL or CLL, with an acceptable toxicity profile.Leukemia research 12/2011; 36(6):709-14. · 2.36 Impact Factor -
Article: Clinical practice guidelines for first-line/after-relapse treatment of patients with follicular lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Key points and recommendations Follicular lymphoma is a subgroup of non-Hodgkin lymphomas of B-cell origin, characterized by a pattern of remissions and continued relapses. It is the second most common type of lymphoid cancer in Western Europe, representing 22-40% of non-Hodgkin lymphomas. The annual incidence of the disease has increased in recent decades. At this time, and with the arrival of new treatment options, patients' outcomes have significantly improved. It is therefore essential to standardize recommendations for the treatment and follow-up of patients with follicular lymphoma, in each clinical scenario. Searches were performed in Medline (PubMed, 1966-present) and The Cochrane Library, using MeSH (Medical Subject Headings) terms whenever possible. The best scientific evidence was obtained from selected randomized studies and meta-analyses. For recommendations where there was no scientific evidence, the consensus of clinical experts was obtained regarding clinical and therapeutic attitudes to improve the treatment of these patients. Recommendations are compiled according to: (i) induction treatment in first-line; (ii) post-induction treatment in first-line; (iii) rescue treatment after relapse; (iv) post-induction treatment in relapse and (v) subsequent treatments. There are different recommendations for each group. They take into account different variables, such as therapeutic options, patient follow-up, laboratory and imaging data, previous response and special groups. The recommendations contained in this guide have been assigned different grades (A, B, C and D), depending on the level of evidence on which they are based (where there is no scientific evidence, they follow the consensus of Good Clinical Practice: see the Appendix). These guidelines provide healthcare professionals with updated and consensual tools for the better management of patients with follicular lymphoma.Leukemia & lymphoma 12/2011; 52 Suppl 3:1-14. · 2.40 Impact Factor -
Article: Primary cutaneous diffuse large B-cell lymphoma, leg type and secondary cutaneous involvement by testicular B-cell lymphoma share identical clinicopathological and immunophenotypical features.
[show abstract] [hide abstract]
ABSTRACT: Primary cutaneous diffuse large B-cell lymphoma (PCDLBCL), leg type can eventually disseminate to extracutaneous sites including testes. In addition, patients with testicular lymphoma can develop specific skin involvement. We sought to describe similarities between PCDLBCL, leg type and testicular B-cell lymphoma affecting the skin. We report two cases with typical clinicopathological and immunophenotypical features of leg type lymphoma occurring simultaneously with a testicular B-cell lymphoma. We also report an additional case of PCDLBCL, leg type with secondary testicular involvement. All cases presented with typical red tumors exclusively located on the legs. Histologically, all cases showed a diffuse nonepidermotropic infiltrate composed of large blastic cells mainly centroblastic type. Phenotype showed strong positivity for Bcl-2, MUM-1, and FOXP1. Epstein-Barr virus stains and CD30 were negative in the 3 cases. In all cases the testicular infiltration showed the same pathological and phenotypical changes to those observed in the skin. This was a retrospective case series study. Skin involvement by testicular B-cell lymphomas and PCDLBCL, leg type are indistinguishable on the basis of pathologic and immunophenotypical features, therefore specific investigation and clinic correlation are needed.Journal of the American Academy of Dermatology 08/2011; 66(4):650-4. · 3.99 Impact Factor -
Article: Intermediate dose of nonpegylated liposomal doxorubicin combination (R-CMyOP) as first line chemotherapy for frail elderly patients with aggressive lymphoma.
[show abstract] [hide abstract]
ABSTRACT: 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.Leukemia research 03/2011; 35(3):358-62. · 2.36 Impact Factor -
Article: Frontline treatment of follicular lymphoma with fludarabine, cyclophosphamide, and rituximab followed by rituximab maintenance: toxicities overcome its high antilymphoma effect. Results from a Spanish Cooperative Trial (LNHF-03).
[show abstract] [hide abstract]
ABSTRACT: We assessed the efficacy of fludarabine, cyclophosphamide, and rituximab in combination (FCR) as frontline treatment in patients with follicular lymphoma (FL) followed by rituximab maintenance. Seventy-five untreated patients with FL received FCR followed by maintenance with rituximab 375 mg/m(2) weekly during 4 weeks and every 6 months for 2 years. The overall response rate was 100%, with 89% complete remission (CR) and 11% partial remission (PR). Molecular remission was observed in all but one patient. Only eight patients completed all therapy planned. With a median follow-up of 47 months, the 5-year overall survival (OS), progression-free survival (PFS), and event-free survival (EFS) were 77%, 93%, and 72%, respectively. Age below 60 and low Follicular Lymphoma International Prognostic Index (FLIPI) correlated with a better EFS. Ten patients died due to toxic complications. The FCR regimen is highly effective in untreated patients with FL, with 89% CR, including molecular responses, and a low progression rate. However, the high incidence of treatment-related mortality makes this regimen unsafe and it cannot be recommended as an upfront therapy in FL.Leukemia & lymphoma 03/2011; 52(3):409-16. · 2.40 Impact Factor -
Article: Modulation of JAK2 V617F allele burden dynamics by hydroxycarbamide in polycythaemia vera and essential thrombocythaemia patients.
[show abstract] [hide abstract]
ABSTRACT: The modulation of JAK2 V617F allele burden dynamics was prospectively analysed in 47 patients (26 polycythaemia vera [PV] and 21 essential thrombocythaemia [ET]) treated with first-line hydroxyurea (HU) and compared with the JAK2 V617F dynamics of a control group of 45 PV and ET patients. A partial molecular response (PMR), according to European Leukaemia Net criteria, was observed in 27/47 (57%) patients. Median time to PMR was 14 months (3-66) with a probability of PMR at 3 years of 57%. A significant decrease in JAK2 V617F allele load was observed at 36 months both in PV and ET patients, being the reduction in PV higher than in ET patients (P = 0·01). A haematocrit ≥0·45 L/L was associated with a higher probability of attaining a PMR (HR:3·4; 95%CI:1·02-11·6, P = 0·04). Control group showed a slight increase of JAK2 V617F allele burden over time. The reduction in the mutated allele load comparing treated patients versus controls was highly significant both in PV and ET, demonstrating a clear effect of HU on the JAK2 V617F allele burden. In conclusion, first-line HU can attain PMR in more than 50% of newly diagnosed PV and ET patients, with a continuous decrease of the JAK2 V617F allele burden in PV patients during treatment.British Journal of Haematology 02/2011; 152(4):413-9. · 4.94 Impact Factor -
Article: NT-proBNP: a cardiac biomarker to assess prognosis in non-Hodgkin lymphoma.
[show abstract] [hide abstract]
ABSTRACT: 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.Leukemia research 02/2011; 35(6):715-20. · 2.36 Impact Factor -
Article: Anemia and erythropoiesis-stimulating agent administration in patients with non-Hodgkin lymphoma treated with cyclophosphamide, doxorubicin, vincristine, and prednisolone ± rituximab chemotherapy: results from an observational study.
[show abstract] [hide abstract]
ABSTRACT: CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) ± rituximab [(± R)CHOP] is the current standard of care for aggressive non-Hodgkin lymphoma (NHL). Anemia resulting from chemotherapy can be treated with erythropoiesis-stimulating agents (ESAs). As part of the observational IMPACT NHL study, data were collected on ESA use and anemia-related outcomes in 1829 adults receiving (± R)CHOP-14 or (± R)CHOP-21. Overall, 33% of patients were anemic during chemotherapy. Older age, lower baseline hemoglobin (Hb), worse performance status, more advanced disease stage, and use of CHOP-14 were significant predictors of transfusion and anemia in logistic regression models. ESAs were received by 404 patients, usually in response to low or declining Hb levels. Most patients (65%) had Hb 9-11 g/dL at ESA initiation, and 89% (Kaplan-Meier percentage) achieved Hb 10-12 g/dL. In conclusion, two-thirds of anemic patients with NHL receiving (± R)CHOP initiated ESA treatment at Hb 9-11 g/dL, and most achieved target Hb levels (10-12 g/dL).Leukemia & lymphoma 02/2011; 52(5):796-803. · 2.40 Impact Factor -

Article: Clinical significance of occult cerebrospinal fluid involvement assessed by flow cytometry in non-Hodgkin's lymphoma patients at high risk of central nervous system disease in the rituximab era.
[show abstract] [hide abstract]
ABSTRACT: Flow cytometry (FCM) analysis of cerebrospinal fluid (CSF) is more sensitive than conventional cytology (CC) for diagnosis of lymphomatous meningeosis, but the clinical significance of occult central nervous system (CNS) disease (positive FCM with negative CC) remains unknown. Patients and CSF samples from 105 patients with newly diagnosed aggressive lymphomas at high risk of CNS involvement were prospectively studied by both CC and FCM, and results were correlated with cumulative incidence of CNS relapse and overall survival (OS). Patients were divided into three groups: 1) patients without CNS involvement (CC-/FCM-; n=83); 2) individuals with occult CNS disease (FCM+/CC-; n=15); and 3) cases with CNS disease (CC+/FCM+; n=7). Six cases showed CNS relapse or progression: two in Group 1 (2.4%), two in Group 2 (13%) and two in Group 3 (28.5%) (Group 2 vs. 1, P=0.04; Group 3 vs. 1, P<0.001). Patients from Groups 2 (P=0.05) and 3 (P<0.001) also showed a higher cumulative incidence of CNS relapse than those from Group 1. Significant differences were observed in OS between FCM-/CC- and FCM+/CC+ cases (P=0.02), while patients with occult CNS disease (FCM+/CC-) displayed intermediate OS rates, although differences did not reach statistical significance. The presence of occult CNS involvement at diagnosis in patients with NHL at high risk of CNS disease is associated with a higher probability of CNS relapse.European Journal Of Haematology 10/2010; 85(4):321-8. · 2.61 Impact Factor -
Article: Cytogenetic aberrations and their prognostic value in a series of 330 splenic marginal zone B-cell lymphomas: a multicenter study of the Splenic B-Cell Lymphoma Group.
[show abstract] [hide abstract]
ABSTRACT: We conducted a retrospective collaborative study to cytogenetically characterize splenic marginal zone lymphoma (SMZL) and ascertain the prognostic value of chromosomal aberrations. Of 330 cases, 72% displayed an aberrant karyotype, 53% were complex, and 29% had a single aberration. The predominant aberrations were gains of 3/3q and 12q, deletions of 7q and 6q and translocations involving 8q/1q/14q. CD5 expression was detected in 39 of 158 cases (25%). The cytogenetic makeup of the CD5(+) group differed significantly from that of the CD5(-) group. Cases with unmutated IGHV were significantly associated with deletions of 7q and TP53. A strong association was noted between usage of the IGVH1-2 and deletion 7q, 14q alterations, and abnormal karyotype. On univariate analysis, patients with more than or equal to 2 aberrations, 14q alterations, and TP53 deletions had the shortest survival; 7q deletion did not affect survival. On multivariate analysis, cytogenetic aberrations did not retain prognostic significance; the parameters negatively affecting survival were hemoglobin and age. In conclusion, the cytogenetic profile of SMZL is distinct from other B-cell lymphomas. Complexity of the karyotype, 14q aberrations, and TP53 deletions are poor prognostic indicators and may be considered together with other clinicobiologic parameters to ascertain the prognosis of SMZL.Blood 09/2010; 116(9):1479-88. · 9.90 Impact Factor -
Article: Successful dexrazoxane treatment of a potentially severe extravasation of concentrated doxorubicin.
[show abstract] [hide abstract]
ABSTRACT: Dexrazoxane is now authorized for the treatment of anthracycline extravasations. Several clinical cases of doxorubicin extravasation treated with dexrazoxane have been reported to date, but detailed cases have not been published. We report a case of a successful dexrazoxane treatment for a potentially severe extravasation of concentrated doxorubicin. We also describe objective outcome of this treatment, drug tolerance to dexrazoxane and long follow-up. A 29-year-old man diagnosed with Hodgkin's lymphoma was prescribed a regimen including 90 mg of doxorubicin in a 50 ml infusion using a reduced occlusion infusion pump. After this infusion, the patient complained of pain around the site of injection and presented a 10x6-cm swollen area with erythema and inflammation. A significant portion of doxorubicin was extravasated. Dexrazoxane was prescribed as an antidote. Side effects of dexrazoxane were restricted to reversible hematological toxicity, nausea, and vomiting. The next day, the inflammation of the extravasation area was reduced. On day 7, a painless mild induration in the extravasated area was the only remaining sign of the extravasation. On day 40, an arm nuclear magnetic resonance image showed no focal injuries. At 6-month follow-up, the patient has no sequelae. The two risk factors that could have increased the severity of the extravasation are the use of an infusion pump and the high drug concentration. Dexrazoxane proved to be effective and moderately well tolerated. A dexrazoxane stock in oncological facilities could help to promptly handle emergencies like this. Anthracyclines can be administered using reduced occlusion infusion pumps, but it seems preferable to always administer a free-running infusion to minimize accidents like this one.Anti-cancer drugs 09/2010; 21(8):790-4. · 2.23 Impact Factor -
Article: A molecular risk score based on 4 functional pathways for advanced classical Hodgkin lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Despite improvement in the treatment of advanced classical Hodgkin lymphoma, approximately 30% of patients relapse or die as result of the disease. Current predictive systems, determined by clinical and analytical parameters, fail to identify these high-risk patients accurately. We took a multistep approach to design a quantitative reverse-transcription polymerase chain reaction assay to be applied to routine formalin-fixed paraffin-embedded samples, integrating genes expressed by the tumor cells and their microenvironment. The significance of 30 genes chosen on the basis of previously published data was evaluated in 282 samples (divided into estimation and validation sets) to build a molecular risk score to predict failure. Adequate reverse-transcription polymerase chain reaction profiles were obtained from 262 of 282 cases (92.9%). Best predictor genes were integrated into an 11-gene model, including 4 functional pathways (cell cycle, apoptosis, macrophage activation, and interferon regulatory factor 4) able to identify low- and high-risk patients with different rates of 5-year failure-free survival: 74% versus 44.1% in the estimation set (P < .001) and 67.5% versus 45.0% in the validation set (P = .022). This model can be combined with stage IV into a final predictive model able to identify a group of patients with very bad outcome (5-year failure-free survival probability, 25.2%).Blood 08/2010; 116(8):e12-7. · 9.90 Impact Factor -
Article: Incidence and prognostic impact of secondary cytogenetic aberrations in a series of 145 patients with mantle cell lymphoma
[show abstract] [hide abstract]
ABSTRACT: Mantle cell lymphoma (MCL) is a mature B-cell neoplasm with an aggressive behavior, characterized by the t(11;14)(q13;q32). Several secondary genetic abnormalities with a potential role in the oncogenic process have been described. Studies of large MCL series using conventional cytogenetics, and correlating with proliferation and survival, are scarce. We selected 145 MCL cases at diagnosis, displaying an aberrant karyotype, from centers belonging to the Spanish Cooperative Group for Hematological Cytogenetics. Histological subtype, proliferative index and survival data were ascertained. Combined cytogenetic and molecular analyses detected CCND1 translocations in all cases, mostly t(11;14)(q13;q32). Secondary aberrations were present in 58% of patients, the most frequent being deletions of 1p, 13q and 17p, 10p alterations and 3q gains. The most recurrent breakpoints were identified at 1p31-32, 1p21-22, 17p13, and 1p36. Aggressive blastoid/pleomorphic variants displayed a higher karyotypic complexity, a higher frequency of 1p and 17p deletions and 10p alterations, a higher proliferation index and poor survival. Gains of 3q and 13q and 17p13 losses were associated with reduced survival times. Interestingly, gains of 3q and 17p losses added prognostic significance to the morphology in a multivariate analysis. Our findings confirm previous observations indicating that proliferation index, morphology and several secondary genetic alterations (3q gains and 13q and 17p losses) have prognostic value in patients with MCL. Additionally, we observed that 3q gains and 17p losses detected by conventional cytogenetics are proliferation-independent prognostic markers indicating poor outcome. © 2010 Wiley-Liss, Inc.Genes Chromosomes and Cancer 02/2010; 49(5):439 - 451. · 3.31 Impact Factor
