Article: Diffuse large B-cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoid malignancy in adults accounting for 31% of all NHL in Western Countries. Following, morphological, biological and clinical studies have allowed the subdivision of DLBCLs into morphological variants, molecular and immunophenotypic subgroups and distinct disease entities. However, a large number of cases still remain biologically and clinically heterogeneous, for which there are no clear and accepted criteria for subclassification; these are collectively termed DLBCL, not otherwise specified (NOS). DLBCL-NOS occurs in adult patients, with a median age in the seventh decade, but the age range is broad, and it may also occur in children. Clinical presentation, behaviour and prognosis are variable, depending mainly of the extranodal site when they arise. These malignancies present in localized manner in approximately 20% of patients. Disseminated extranodal disease is less frequent, and one third of patients have systemic symptoms. Overall, DLBCLs are aggressive but potentially curable malignancies. Cure rate is particularly high in patients with limited disease with a 5-year PFS ranging from 80% to 85%; patients with advanced disease have a 5-year PFS≈50%. The International Prognostic Index (IPI) and age adjusted IPI (aaIPI) are the benchmarks of DLBCL prognosis. First-line treatment for patients with DLBCL is based on the individual IPI score and age, and three major subgroups should be considered: elderly patients (>60years, aaIPI=0-3); young patients with low risk (<60years, aaIPI=0-1); young patients with high risk (<60years, aaIPI=2-3). The combination of the anti-CD20 monoclonal antibody rituximab and CHOP chemotherapy, every 14 or 21days, is the standard treatment for DLBCL patients. Recent randomized trials suggest that high-dose chemotherapy supported by autologous stem cell transplant (HDC/ASCT) should not be used as upfront treatment for young high-risk patients outside prospective clinical trials. HDC/ASCT is actually recommended in young patients who did not achieve CR after first-line chemotherapy. Consolidation radiotherapy should be reserved to patients with bulky disease who did not achieve CR after immunochemotherapy. Patients with high IPI score, which indicates increased LDH serum level and the involvement of more than one extranodal site, and patients with involvement of certain extranodal sites (a.e., testes and orbit) should receive CNS prophylaxis as part of first-line treatment. HDC/ASCT should be considered the standard therapy for DLBCL patients with chemotherapy-sensitive relapse. Overall results in patients who cannot be managed with HDC/ASCT due to age or comorbidity are disappointing. New effective and less toxic chemotherapy drugs or biological agents are also worth considering for this specific and broad group of patients. Several novel agents are undergoing evaluation in DLBCL; among other, immunomodulating agents (lenalidomide), m-TOR inhibitors (temsirolimus and everolimus), proteasome inhibitors (bortezomib), histone deacetylase inhibitors (vorinostat), and anti-angiogenetic agents (bevacizumab) are being investigated in prospective trials.Critical reviews in oncology/hematology 01/2013; · 5.27 Impact Factor -
Article: Addition of Rituximab to Chlorambucil Produces Superior Event-Free Survival in the Treatment of Patients With Extranodal Marginal-Zone B-Cell Lymphoma: 5-Year Analysis of the IELSG-19 Randomized Study.
[show abstract] [hide abstract]
ABSTRACT: PURPOSEApart from localized gastric disease, there is no consensus on standard initial treatment of mucosa-associated lymphoid tissue lymphoma. The IELSG-19 study (Randomized Trial of Chlorambucil Versus Chlorambucil Plus Rituximab Versus Rituximab in MALT Lymphoma) was launched to compare chlorambucil alone versus chlorambucil plus rituximab in patients not previously given systemic anticancer therapy. PATIENTS AND METHODS Patients not responding to or not suitable for local therapy were eligible. In arm A, chlorambucil was given daily 6 mg/m(2) orally (PO) for 6 weeks. Responding patients and those with stable disease continued to be given daily chlorambucil 6 mg/m(2) PO for 14 consecutive days every 28 days for four cycles. In arm B, intravenous rituximab 375 mg/m(2) per day was added on days 1, 8, 15, 22, 56, 84, 112, and 140. After completion of the planned accrual, the protocol was amended to introduce a third arm with rituximab alone. We report the planned final analysis of the first two arms (113 patients in arm A and 114 in arm B).ResultsAt a median follow-up of 62 months, the 5-year event-free survival (EFS) was significantly better for the patients treated in arm B (68% v 50%; P = .002) who, despite similar overall response rates (90% v 87%), achieved a higher complete remission rate (78% v 65%; P = .025). Progression-free survival was also improved but it did not reach statistical significance (P = .057). Five-year overall survival (OS) was 89% in both arms. Both treatments were well tolerated without unexpected toxicities. CONCLUSION Both treatments were active; the better response rate and EFS obtained with the addition of rituximab did not translate into improved OS.Journal of Clinical Oncology 01/2013; · 18.37 Impact Factor -
Article: SIE, SIES, GITMO revised guidelines for the management of follicular lymphoma.
[show abstract] [hide abstract]
ABSTRACT: By using the GRADE system, we updated the guidelines for management of follicular cell lymphoma issued in 2006 from SIE, SIES, and GITMO group. We confirmed our recommendation to frontline chemoimmunotherapy in patients with Stage III-IV disease and/or high tumor burden. Maintenance rituximab was also recommended in responding patients. In patients relapsing after an interval longer than 12 months from frontline therapy, we recommended chemoimmunotherapy with non cross-resistant regimens followed by rituximab maintenance. High dose chemotherapy followed by hematopoietic stem cell transplant was recommended for young fit patients who achieve a response after salvage chemoimmunotherapy.American Journal of Hematology 12/2012; · 4.67 Impact Factor -
Article: Role of radiotherapy in patients with early-stage diffuse large B-cell lymphoma of Waldeyer's ring in remission after anthracycline-containing chemotherapy.
[show abstract] [hide abstract]
ABSTRACT: Consolidation radiotherapy (cRT) in patients with stage I/II diffuse large B-cell lymphoma of the Waldeyer's ring (WR-DLBCL) in complete remission (CR) after induction chemotherapy (CHT) is often associated with relevant acute and chronic toxicity, and its impact on survival remains to be defined. A total of 184 patients in CR after anthracycline-based chemotherapy were retrospectively analyzed: 62 underwent CHT alone (CHT group), while 122 (66%) patients were referred to cRT (CHT + RT group). After a median follow-up of 54 months, 36 patients (20%) experienced relapse: 19% in the CHT group and 20% in the CHT + RT group. At the time of analysis 47 (76%) CHT patients and 97 (80%) CHT + RT patients were alive. Five-year overall survival (OS), disease-free survival (DFS) and lymphoma-specific survival (LSS) were 80%, 74% and 86%, respectively. Five-year OS was significantly prolonged in the CHT + RT group, while DFS and LSS were similar between groups. This discrepancy was attributed to a high percentage of deaths due to unrelated causes in CHT patients. cRT does not prolong LSS in patients with early-stage WR-DLBCL in CR after anthracycline-containing chemotherapy. An international confirmatory trial is warranted.Leukemia & lymphoma 07/2012; · 2.40 Impact Factor -

Article: Behind the scenes of non-nodal MCL: downmodulation of genes involved in actin cytoskeleton organization, cell projection, cell adhesion, tumour invasion, TP53 pathway and mutated status of immunoglobulin heavy chain genes.
[show abstract] [hide abstract]
ABSTRACT: Mantle cell lymphoma (MCL) is an aggressive neoplasm with a short survival. Cases with leukaemic MCL and splenomegaly without adenopathies (non-nodal MCL) may have a more indolent course. To gain insights into the biological features underlying this presentation, we investigated the gene expression profile (GEP) and the IGHV mutational status in a cohort of leukaemic MCL cases. Comparison of MCL with other lymphoproliferative disorders (i.e. splenic marginal zone lymphoma, follicular lymphoma, chronic lymphocytic leukaemia) revealed a MCL signature enriched for the following gene categories: mitochondrion, oxidoreductase activity, response to stress, to DNA damage and TP53-pathway. Furthermore, GEP analysis revealed that non-nodal MCL cases were characterized by the down-modulation of the following gene categories: cell projection, actin cytoskeleton organization, cell adhesion (ITGAE, CELSR1, PCDH9) and tumour invasion/progression (PGF, ST14, ETS1, OCIAD1, EZR). Many down-modulated genes were related to the TP53-pathway and to DNA damage response. IGHV status proved unmutated in all nodal and mutated in all non-nodal MCL. Non-nodal leukaemic MCLs display a peculiar clinical presentation, with distinctive biological features, such as mutated IGHV and a transcriptional profile lacking tumour invasion properties, that might contribute to the absence of nodal involvement and to the less aggressive clinical course.British Journal of Haematology 12/2011; 156(5):601-11. · 4.94 Impact Factor -
Article: Overview of alemtuzumab therapy for the treatment of T-cell lymphomas.
[show abstract] [hide abstract]
ABSTRACT: Alemtuzumab is a humanized monoclonal antibody that recognizes the CD52 antigen expressed on malignant and normal B lymphocytes. It has come to be used therapeutically in B-cell malignancies and, in addition, it shows interesting activity also in T-cell lymphomas. Published literature and abstract proceedings were scanned, and a systematic review of phase II studies administering alemtuzumab in patients with T-cell lymphomas was performed. Alemtuzumab is an effective alternative option for patients with peripheral T-cell lymphomas and cutaneous T-cell lymphomas. Alemtuzumab may belong to the current standard of care for nodal and cutaneous T-cell lymphomas.Leukemia & lymphoma 11/2011; 53(5):789-95. · 2.40 Impact Factor -

ABSTRACT: Therapy-related myelodysplastic syndromes are possible complications in patients treated for previous hematologic malignancies. Therapeutic strategies in these type of disorders are still not well defined: azacitidine has been recently approved for the treatment of higher risk myelodysplastic syndromes, but few data are published relating possible efficacy in therapy-related dysplastic disorders.

Article: First-line treatment for primary testicular diffuse large B-cell lymphoma with rituximab-CHOP, CNS prophylaxis, and contralateral testis irradiation: final results of an international phase II trial.
[show abstract] [hide abstract]
ABSTRACT: Primary testicular lymphoma (PTL) has poor prognosis with failures in contralateral testis, CNS, and extranodal sites. To prevent these events, we designed an international phase II trial (International Extranodal Lymphoma Study Group 10 [IELSG-10]) that addressed feasibility and activity of conventional chemoimmunotherapy associated with CNS prophylaxis and contralateral testis irradiation. The trial was conducted by the IELSG and the Italian Lymphoma Foundation. Fifty-three patients (age 22 to 79 years) with untreated stage I or II PTL were treated with six to eight courses of rituximab added to cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) every 21 days (R-CHOP21); four doses of intrathecal methotrexate (IT-MTX) and radiotherapy (RT) to the contralateral testis (30 Gy) for all patients and to regional lymph nodes (30 to 36 Gy) for stage II disease. All patients received R-CHOP21, 50 received CNS prophylaxis, and 47 received testicular RT. With a median follow-up of 65 months, 5-year progression-free survival and overall survival rates were 74% (95% CI, 59% to 84%) and 85% (95% CI, 71% to 92%), respectively. Ten patients relapsed or progressed: two in lymph nodes, five in extranodal organs, and three in the CNS. The 5-year cumulative incidence of CNS relapse was 6% (95% CI, 0% to 12%). No contralateral testis relapses occurred. Ten patients died: lymphoma (n = 6), secondary leukemia (n = 2), heart failure (n = 1), and gastric cancer (n = 1). Grade 3 to 4 toxicities were neutropenia, 28%; infections, 4%; and neurologic, 13%. No deaths occurred as a result of toxicity. This international prospective trial shows that combined treatment with R-CHOP21, IT-MTX, and testicular RT was associated with a good outcome in patients with PTL. RT avoided contralateral testis relapses, but CNS prophylaxis deserves further investigation.Journal of Clinical Oncology 06/2011; 29(20):2766-72. · 18.37 Impact Factor -
Article: High response rate and improvement of long-term survival with combined treatment modalities in patients with poor-risk primary thyroid diffuse large B-cell lymphoma: an International Extranodal Lymphoma Study Group and Intergruppo Italiano Linfomi study.
[show abstract] [hide abstract]
ABSTRACT: The impact of different treatment modalities and prognostic factors on the clinical course of primary thyroid diffuse large B-cell lymphoma (PTDLBCL) is still the subject of research. This study was conducted to clarify these clinical aspects of this disorder. The clinical parameters of 48 patients with PTDLBCL at time of diagnosis were comparable to those of previous studies. Patients underwent either radiotherapy (RT) ± surgery (SX), chemotherapy (CHT) alone or in combination with local treatments (RT or SX), or SX followed by CHT and RT. A 90% complete remission (CR) rate was observed among patients who underwent combined treatment modalities (CTM), compared to 76% among the others. The 5-year progression-free survival differed significantly between both groups (p = 0.028). Poor performance status and advanced age correlated with decreased survival. PTDLBCL is a curable disease prevalent in elderly patients. Combined treatment modalities were able to induce an elevated rate of CR, improving long-term survival in younger patients. However, the outcome in elderly patients still remains unsatisfactory.Leukemia & lymphoma 02/2011; 52(5):823-32. · 2.40 Impact Factor -
Article: The host genetic background of DNA repair mechanisms is an independent predictor of survival in diffuse large B-cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Several drugs used for diffuse large B-cell lymphoma (DLBCL) treatment rely on DNA damage for tumor cell killing. We verified the prognostic impact of the host DNA repair genotype in 2 independent cohorts of DLBCL treated with R-CHOP21 (training cohort, 163 cases; validation cohort, 145 cases). Among 35 single nucleotide polymorphisms analyzed in the training series, MLH1 rs1799977 was the sole predicting overall survival. DLBCL carrying the MLH1 AG/GG genotype displayed an increased death risk (hazard ratio [HR] = 3.23; P < .001; q =0 .009) compared with patients carrying the AA genotype. Multivariate analysis adjusted for International Prognostic Index identified MLH1 AG/GG as an independent OS predictor (P < .001). The poor prognosis of MLH1 AG/GG was the result of an increased risk of failing both R-CHOP21 (HR = 2.02; P = .007) and platinum-based second-line (HR = 2.26; P = .044) treatment. Survival analysis in the validation series confirmed all outcomes predicted by MLH1 rs1799977. The effect on OS of MLH1, a component of the DNA mismatch repair system, is consistent with its role in regulating the genotoxic effects of doxorubicin and platinum compounds, which are a mainstay of DLBCL first- and second-line treatment.Blood 12/2010; 117(8):2405-13. · 9.90 Impact Factor -

Article: Cyclophosphamide, doxorubicin, vincristine, methotrexate, bleomicin and prednisone plus rituximab in untreated young patients with low-risk (age-adjusted international prognostic index 0-1) diffuse large B-cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Young patients (aged 18-60 years) with good-prognosis diffuse large B-cell lymphoma (DLBCL) [0 and 1 risk factor according to age-adjusted international prognostic index (aa-IPI)] are distinguished from patients with poor-prognosis. Six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) in combination with rituximab achieved best results in young patients with low-risk DLBCL. We retrospectively analyzed the data of 82 patients (18-60 years) with untreated aa-IPI 0-1 DLBCL, from six Italian institutions, who underwent, between January 2002 and January 2007, rituximab-cyclophosphamide, doxorubicin, vincristine, methotrexate, bleomicin and prednisone (R-MACOP-B) therapy followed, in patients with bulky presentation, by 30-36 Gy involved-field radiation therapy (34 patients). An overall response rate was noted in 77 out of 82 (94%) patients (75 patients had a complete response (91%), 2 patients had a partial response). With a median follow-up of 46 months, 7-year progression-free and overall survival were estimated to be 91% and 94%, respectively. R-MACOP-B regimen followed by involved-field radiation on bulky presentation is safe and very effective in the treatment of young patients with low-risk DLBCL.Leukemia & lymphoma 10/2009; 50(11):1824-9. · 2.40 Impact Factor -
Article: Rituximab combined with MACOP-B or VACOP-B and radiation therapy in primary mediastinal large B-cell lymphoma: a retrospective study.
[show abstract] [hide abstract]
ABSTRACT: Third-generation regimens (MACOP-B [methotrexate/leucovorin (LV)/doxorubicin/cyclophosphamide/vincristine/ prednisone/bleomycin] or VACOP-B [etoposide/LV/doxorubicin/cyclophosphamide/vincristine/prednisone/bleomycin]) in combination with local radiation therapy seem to improve lymphoma-free survival of primary mediastinal large B-cell lymphoma (PMLBCL). Recently, the superiority of R-CHOP (rituximab plus cyclophosphamide/doxorubicin/vincristine/ prednisone) over CHOP-like regimens has been demonstrated in elderly and younger patients with low-risk diffuse large B-cell lymphoma. Retrospectively, between February 2002 and July 2006, 45 previously untreated patients with PMLBCL were treated with a combination of a third-generation chemotherapy regimen (MACOP-B or VACOP-B), concurrent rituximab, and mediastinal radiation therapy. Twenty-six (62%) patients achieved a complete response (CR), and 15 (36%) obtained a partial response after MACOP-B/VACOP-B plus rituximab. After radiation therapy, the CR rate was 80%. At a median follow-up of 28 months, among the 34 patients who obtained a CR, 3 relapsed after 16, 19, and 22 months, respectively. Projected overall survival was 80% at 5 years; the relapse-free survival (RFS) curve of the 34 patients who achieved CR was 88% at 5 years. In this retrospective study, in patients with PMLBCL, combined-modality treatment using the MACOP-B/VACOP-B regimen plus rituximab induces a high remission rate, with patients having a > 80% chance of surviving relapse free at 5 years. In comparison with historical data on MACOP-B/VACOP-B without rituximab, there are no statistically significant differences in terms of CR and RFS rates.Clinical Lymphoma & Myeloma 10/2009; 9(5):381-5. · 1.13 Impact Factor -
Article: Follicular lymphoma international prognostic index 2: a new prognostic index for follicular lymphoma developed by the international follicular lymphoma prognostic factor project.
[show abstract] [hide abstract]
ABSTRACT: The aim of the F2 study was to verify whether a prospective collection of data would enable the development of a more accurate prognostic index for follicular lymphoma (FL) by using parameters which could not be retrospectively studied before, and by choosing progression-free survival (PFS) as principal end point. Between January 2003 and May 2005, 1,093 patients with a newly diagnosed FL were registered and 942 individuals receiving antilymphoma therapy were selected as the study population. The variables we used for score definition were selected by means of bootstrap resampling procedures on 832 patients with complete data. Procedures to select the model that would minimize errors were also performed. After a median follow-up of 38 months, 261 events for PFS evaluation were recorded. beta2-microglobulin higher than the upper limit of normal, longest diameter of the largest involved node longer than 6 cm, bone marrow involvement, hemoglobin level lower than 12 g/dL, and age older than 60 years were factors independently predictive for PFS. Using these variables, a prognostic model was devised to identify three groups at different levels of risk. The 3-year PFS rate was 91%, 69%, and 51% for patients at low, intermediate, and high risk, respectively (log-rank = 64.6; P < .00001). The 3-year survival rate was 99%, 96%, and 84% for patients at low, intermediate, and high risk, respectively (P < .0001). Follicular Lymphoma International Prognostic Index 2 is a simple prognostic index based on easily available clinical data and may represent a promising new tool for the identification of patients with FL at different risk in the era of immunochemotherapy.Journal of Clinical Oncology 09/2009; 27(27):4555-62. · 18.37 Impact Factor -
Article: High-dose cytarabine plus high-dose methotrexate versus high-dose methotrexate alone in patients with primary CNS lymphoma: a randomised phase 2 trial.
[show abstract] [hide abstract]
ABSTRACT: Chemotherapy with high-dose methotrexate is the conventional approach to treat primary CNS lymphomas, but superiority of polychemotherapy compared with high-dose methotrexate alone is unproven. We assessed the effect of adding high-dose cytarabine to methotrexate in patients with newly diagnosed primary CNS lymphoma. This open, randomised, phase 2 trial was undertaken in 24 centres in six countries. 79 patients with non-Hodgkin lymphoma exclusively localised into the CNS, cranial nerves, or eyes, aged 18-75 years, and with Eastern Cooperative Oncology Group performance status of 3 or lower and measurable disease were centrally randomly assigned by computer to receive four courses of either methotrexate 3.5 g/m(2) on day 1 (n=40) or methotrexate 3.5 g/m(2) on day 1 plus cytarabine 2 g/m(2) twice a day on days 2-3 (n=39). Both regimens were administered every 3 weeks and were followed by whole-brain irradiation. The primary endpoint was complete remission rate after chemotherapy. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00210314. All randomly assigned participants were analysed. After chemotherapy, seven patients given methotrexate and 18 given methotrexate plus cytarabine achieved a complete remission, with a complete remission rate of 18% (95% CI 6-30) and 46% (31-61), respectively, (p=0.006). Nine patients receiving methotrexate and nine receiving methotrexate plus cytarabine achieved a partial response, with an overall response rate of 40% (25-55) and 69% (55-83), respectively, (p=0.009). Grade 3-4 haematological toxicity was more common in the methotrexate plus cytarabine group than in the methotrexate group (36 [92%] vs six [15%]). Four patients died of toxic effects (three vs one). In patients aged 75 years and younger with primary CNS lymphoma, the addition of high-dose cytarabine to high-dose methotrexate provides improved outcome with acceptable toxicity compared with high-dose methotrexate alone.

Article: Primary mediastinal large B-cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Primary mediastinal large B-cell lymphoma (PMLBCL) is a unique type of B-cell lymphoma probably arising from a putative thymic medulla B-cell. It constitutes 6-10% of all diffuse large B-cell lymphomas (DLBCL), occurring more often in young females. PMLBCL is characterized by a diffuse proliferation of medium to large B-cells associated with sclerosis and a degree of compartmentalisation. Its main molecular characteristics include: gains in 9p segments, p53 mutations, BCL-2 and MAL gene over-expression, somatic mutations of IgVH genes, BCL-6, PIM-1, PAX-5, RhoH/TTF, and c-MYC, and constitutional NF-kappaB activation. The gene expression signature of PMLBCL seems to be much closer to classic Hodgkin lymphoma than to DLBCL. PMLBCL is characterized by a locally invasive anterior mediastinal mass, often producing cough, chest pain, dyspnea, and superior vena cava syndrome. Most PMLBCL patients have stage I-II, bulky disease, with pleural or pericardial effusions in a third of cases. Systemic symptoms, mainly fever or weight loss, are present in <20% of cases; increased LDH levels are observed in 70-80% of cases. Treatment with CHOP regimen followed by radiation therapy was associated with a 5-year survival of 65%. Apparently better results have been reported with third-generation weekly alternating regimens followed by radiation therapy. Any recurrence is almost always seen in the first 2 years of follow-up, and distant relapses tend to involve extranodal organs. Features associated with poor prognosis are poor performance status, pericardial effusion, bulky disease, high serum LDH at diagnosis, and a compromised dose-intensity of anthracycline and cyclophosphamide.Critical Reviews in Oncology/Hematology 09/2008; 68(3):256-63. · 4.41 Impact Factor -
Article: The addition of rituximab to anthracycline-based chemotherapy significantly improves outcome in 'Western' patients with intravascular large B-cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: Some case reports and a Japanese series suggest benefit from the use of rituximab in patients with intravascular large B-cell lymphoma (IVL). Rituximab efficacy was evaluated in Western patients with IVL, comparing outcome of 10 patients treated with rituximab + chemotherapy (R-CT) and of 20 patients treated with chemotherapy alone (CT). There were no significant differences in patients' characteristics between the two subgroups. The addition of rituximab was associated with improved complete remission rate (90% vs. 50%; P = 0.04), event-free survival (3-year: 89% vs. 35%; P = 0.003) and overall survival (3-year: 89% vs. 38%; P = 0.01). In conclusion, rituximab may substantially change the dismal prognosis of IVL.British Journal of Haematology 09/2008; 143(2):253-7. · 4.94 Impact Factor -
Article: Practice guidelines for the management of extranodal non-Hodgkin's lymphomas of adult non-immunodeficient patients. Part I: primary lung and mediastinal lymphomas. A project of the Italian Society of Hematology, the Italian Society of Experimental Hematology and the Italian Group for Bone Marrow Transplantation.

ABSTRACT: Extranodal non-Hodgkin's lymphomas constitute 20-25% of overall non-Hodgkin's lymphomas cases and can be managed with very different therapeutic strategies. Therefore, the Italian Society of Hematology and the two affiliate societies (the Italian Society of Experimental Hematology and the Italian Group of Bone Marrow Transplantation) appointed a panel of experts to produce clinical practice-guidelines for the management of these conditions. Primary lung and mediastinal lymphomas were the objective of this part of the project. The panel of experts produced the following key recommendations that were graded according to the strength of evidence and clinical judgement. The first-line therapy for non-MALT primary lung non-Hodgkin's lymphomas should include anthracycline-based chemotherapy with CHOP or CHOP-like, MACOP-B or MACOP-B-like regimens (grade D). Rituximab association with chemotherapy needs to be evaluated within approved clinical trials. Second-line therapy with high-dose chemotherapy and autologous stem cell transplantation is recommended (grade B). In patients with MALT primary lung non-Hodgkin's lymphomas, the recommended first-line therapy should include chlorambucil, CHOP, CHOP-like or fludarabine-containing regimens (grade B). Radiotherapy is to be reserved for patients with a unique, small lesion in a poorly mobile site and with contraindication to surgery (grade D). Rituximab should be administered only within approved clinical trials. For treatment of primary mediastinal large B-cell lymphomas, the recommended first-line therapy is a chemotherapy and radiotherapy association (grade B). An anthracycline-based chemotherapy with CHOP, MACOP-B or VACOP-B is recommended (grade B). Rituximab combination with chemotherapy is highly suggested but only for patients enrolled into approved clinical trials. Patients with an inadequate early response should be candidates for early intensification with high-dose chemotherapy (grade C). Patients with refractory or relapsed disease should undergo rescue programs including intensive, non-cross-resistant debulking treatment followed, in chemosensitive patients, by high-dose chemotherapy and autologous stem cell transplantation (grade B).Haematologica 08/2008; 93(9):1364-71. · 6.42 Impact Factor -
Article: MACOP-B and involved-field radiotherapy is an effective and safe therapy for primary mediastinal large B cell lymphoma.
[show abstract] [hide abstract]
ABSTRACT: To report the clinical findings and long-term results of front-line, third-generation MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin) chemotherapy and mediastinal involved-field radiotherapy (IFRT) in 85 consecutive, previously untreated patients with primary mediastinal large B cell lymphoma (PMLBCL) diagnosed and managed at a single institution. Between 1991 and April 2004, 92 consecutive, untreated patients with PMLBCL were treated at our institution. The median age was 33 years (range, 15-61 years), 46 patients (50%) showed a mediastinal syndrome at onset; 52 patients (57%) showed a low/low-intermediate (0 to 1) and 40 patients (43%) an intermediate-high/high (2 to 3) International Prognostic Index (IPI) score. Eighty-five patients were treated with standard chemotherapy (MACOP-B), and 80 underwent mediastinal IFRT at a dose of 30-36 Gy. After a MACOP-B regimen, the overall response rate was 87% and the partial response rate 9%. After chemotherapy, (67)Ga scintigraphy/positron emission tomography results were positive in 43 of 52 patients (83%), whereas after IFRT 11 of 52 patients (21%) remained positive (p < 0.0001). After a median follow-up of 81 months (range, 2-196 months), progression or relapse was observed in 15 of 84 patients (18%). The projected 5-year overall survival and progression-free survival rates were 87% and 81%, respectively. The 5-year overall survival and progression-free survival rates were better for patients with an IPI of 0 to 1 than for those with an IPI of 2 to 3 (96% vs. 73% [p = 0.002] and 90% vs. 67% [p = 0.007], respectively). Combined-modality treatment with intensive chemotherapy plus mediastinal IFRT induces high response and lymphoma-free survival rates. Involved-field RT plays an important role in inducing negative results on (67)Ga scintigraphy/positron emission tomography in patients responsive to chemotherapy.International journal of radiation oncology, biology, physics 06/2008; 72(4):1154-60. · 4.59 Impact Factor
