Lenalidomide maintenance after autologous haematopoietic stem-cell transplantation in mantle cell lymphoma: results of a Fondazione Italiana Linfomi (FIL) multicentre, randomised, phase 3 trial.

Lancet Haematol 2021 Jan 22;8(1):e34-e44. Epub 2020 Dec 22.

Department of Translational and Precision Medicine, Sapienza University of Rome, Roma, Italy.

Background: Fit patients with mantle cell lymphoma aged 18-65 years are usually given cytarabine and rituximab-based induction regimens followed by autologous haematopoetic stem-cell transplantation (HSCT). We investigated whether post-autologous HSCT maintenance with lenalidomide improves progression-free survival in this population.

Methods: This open-label, randomised, multicentre, phase 3 trial was done at 49 haematology and oncology units in Italy and Portugal. Eligible patients had Ann Arbor stage III or IV treatment-naive mantle cell lymphoma (or stage II plus bulky disease [≥5 cm] or B symptoms), and had evidence of cyclin D1 overexpression or the translocation t(11;14)(q13;q32). Patients were aged 18-59 years with Eastern Cooperative Oncology Group (ECOG) performance status 0-3, or aged 60-65 years with ECOG 0-2. After an optional prephase with vincristine and steroids (intravenous vincristine 1·4 mg/m on day 1, oral prednisone 100 mg [total dose] on days 1-5), patients were given three courses of R-CHOP (21-day cycle, intravenous rituximab 375 mg/m on day 1; intravenous doxorubicin 50 mg/m, vincristine 1·4 mg/m, and cyclophosphamide 750 mg/m on day 2; oral prednisone 100 mg/m on day 2-6). Patients then received one cycle of high-dose CTX (intravenous cyclophosphamide 4 g/m on day 1, intravenous rituximab 375 mg/m on day 4). After restaging, patients received two cycles of R-HD-cytarabine (high-dose intravenous cytarabine 2 g/m every 12 h on days 1-3, intravenous rituximab 375 mg/m on days 4 and 10). Patients with complete remission or partial remission proceeded to autologous HSCT and responding patients (complete remission or partial remission) with haematological recovery were randomly assigned (1:1) to receive 24 courses of oral lenalidomide maintenance (15 mg per day for patients with platelets >100 × 10 cells per L or 10 mg per day for platelets 60-100 × 10 cells per L, days 1-21 every 28 days) for 24 months, or observation. The primary endpoint was progression-free survival, measured in the randomised population. This study is registered with EudraCT (2009-012807-25) and ClinicalTrials.gov (NCT02354313).

Findings: Between May 4, 2010, and Aug 24, 2015, 303 patients were screened for inclusion and 300 patients were enrolled (median age 57 years, IQR 51-62; 235 [78%] male). 95 patients were excluded before randomisation, mostly due to disease progression, adverse events, and inadequate recovery. 104 patients were randomly assigned to the lenalidomide maintenance group and 101 patients to the observation group. 11 (11%) of 104 patients assigned to lenalidomide did not start treatment (3 withdrew, 6 adverse events or protocol breach, 2 lost to follow-up). At a median follow-up of 38 months after randomisation (IQR 24-50), 3-year progression-free survival was 80% (95% CI 70-87) in the lenalidomide group versus 64% (53-73) in the observation group (log-rank test p=0·012; hazard ratio 0·51, 95% CI 0·30-0·87). 41 (39%) of 104 patients discontinued lenalidomide for reasons including death or progression. Treatment-related deaths were recorded in two (2%) of 93 patients in the lenalidomide group (1 pneumonia, 1 thrombotic thrombocytopenic purpura), and one (1%) of 101 in the observation group (pneumonia). 59 (63%) of 93 patients in the lenalidomide group had grade 3-4 haematological adverse events versus 12 (12%) of 101 patients in the observation group (p<0·0001). 29 (31%) of 93 patients in the lenalidomide group and eight (8%) of 101 patients in the observation group had grade 3-4 non-haematological adverse events (p<0·0001), of which infections were the most common.Serious adverse events were reported in 22 (24%) of 93 patients in the lenalidomide group and five (5%) of 101 patients in the observation group. Pneumonia and other infections were the most common serious adverse events.

Interpretation: Despite non-negligibile toxicity, lenalidomide after autologous HSCT improved progression-free survival in patients with mantle cell lymphoma, highlighting the role of maintenance in mantle cell lymphoma.

Treatment and outcomes of primary mediastinal B cell lymphoma: a three-decade monocentric experience with 151 patients.

Ann Hematol 2020 Dec 10. Epub 2020 Dec 10.

IRCCS - Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Primary mediastinal B cell lymphoma is a rare entity and often should be promptly treated as a hematological emergency: The initial treatment decision is crucial for the management of this disease. An observational retrospective study was conducted with the aim to improve information on treatment and outcomes of primary mediastinal B cell lymphoma in real practice. After 12 cycles of MACOP-B regimen (methotrexate, doxorubicin, cyclophosphamide, vincristine, bleomycin , and prednisone) with or without rituximab, 120 patients out of 151 (79.5%) achieved a complete response and 12 (7.9%) a partial response leading to a global response of 87.4%. The 21-year overall survival is 82.6%; progression-free and disease-free survivals are 69.3% and 86.4%, respectively. Regarding the role of radiotherapy (RT), patients with a negative PET scan after MACOP-B did not undergo RT: One out of these 48 (2.1%) showed a relapse at 11 months. All relapsed/refractory patients who achieved a response with checkpoint inhibitors are still in continuous complete response with a median follow-up of 14 months. Data that we have gathered over a 30-year experience in the treatment of primary mediastinal B cell lymphoma patients clearly indicate that a third-generation chemotherapy regimen such as MACOP-B is feasible and easily deliverable on an outpatient basis. Regarding the unmet medical need of relapsed/refractory patients, new encouraging results occurred with the advent of the checkpoint inhibitors.

Potential survival benefit for patients receiving autologous hematopoietic stem cell transplantation after checkpoint inhibitors for relapsed/refractory Hodgkin lymphoma: A real-life experience.

Hematol Oncol 2020 Dec 30;38(5):737-741. Epub 2020 Sep 30.

Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italia.

In recent years, novel drugs are available for the patients with relapsed/refractory Hodgkin lymphoma (HL), like immune checkpoint inhibitors (CPi). These drugs have been able to rescue a cohort of patients who subsequently could receive an allogeneic stem-cell transplant (SCT). No data were reported for subsequent autologous SCT (ASCT) after CPi. Here, we report our real-life experience in heavily pretreated HL patients undergoing ASCT as consolidation approach after CPi treatment. A retrospective observational study was conducted. Patients had CPi therapy in the context of clinical trials (n = 6) or in the named patient program (n = 7) between July 2014 and November 2019: 9 out of 13 received pembrolizumab and the remaining four underwent nivolumab. A median of 12 cycles (range, 3-16) of CPi therapy were infused. Thirteen patients underwent ASCT after CPi: 11 (84.6%) patients obtained a complete response (CR) and 2 had progression of disease, with an overall response rate of 84.6%. With a median follow-up of 3.3 years (range, 1.1-5.5), only one CR patient had disease relapse after 3.9 months from ASCT, leading to an estimated disease-free survival of 87.5% at 56.9 months. The estimated 5-year progression-free survival was 73.4% and overall survival was 92.3% at 4.8 years, respectively. No unexpected or cumulative toxicity was observed. Our results indicated that ASCT may represent a further effective therapeutic option as consolidation in HL after CPi treatment that today represents the last conventionally recognized therapeutic line.

Effectiveness of chemotherapy after anti-PD-1 blockade failure for relapsed and refractory Hodgkin lymphoma.

Cancer Med 2020 11 2;9(21):7830-7836. Epub 2020 Sep 2.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

Programmed death-1 (PD1) blockade is an efficient and safe therapeutic option in patients with relapsed/refractory (R/R) classical Hodgkin lymphoma (cHL). However, a substantial proportion of patients' progresses or loses the response to anti-PD1 treatment. We retrospectively investigated the effectiveness of salvage chemotherapies (CHT) for unsatisfactory response to anti-PD1, in 25 R/R cHL patients. Twenty-three patients (92%) were refractory to the last treatment before anti-PD1. After a median of 14 cycles (range 3-52), 68% (17/25) of patients had unsatisfactory responses to anti-PD1 therapy, whereas 6 had a partial response (PR) and 2 patients achieved complete response (CR), with an overall response rate (ORR) of 32%. After a median time of 1.5 months, 15 patients received a single agent treatment and 10 had a multi-agents regimen, due to the failure of PD1 blockade. The ORR was 60% (8 CR and 7 PR). Seven patients (3 in PR and 4 in CR) underwent a consolidation strategy with stem cell transplantation. Median progression-free survival (PFS) with salvage treatment was reached at 19.1 months, while median PFS after anti-PD1 has been reached at 8.2 months. After a median follow-up of 32.4 months, 6 patients died while 13 are still in CR. The median overall estimated from the start of CHT was not reached. The efficacy of treatment following anti-PD1 is not yet established, especially in lymphoma patients. To note, in our series, a subset of heavily pre-treated and chemo-refractory patients increased response rates to and survival with CHT given after exposure to immune-checkpoint inhibitors.

Bendamustine-rituximab regimen in untreated indolent marginal zone lymphoma: experience on 65 patients.

Hematol Oncol 2020 Oct 29;38(4):487-492. Epub 2020 Jul 29.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

First line therapy of patients with marginal zone lymphomas (MZL) is not well established and various regimens with chemo-immunotherapy can be used. Rituximab plus bendamustine (BR) is an effective and manageable treatment option for patients affected by indolent non-Hodgkin lymphoma. The aim of this monocentric retrospective study was to analyze the effectiveness and safety of the use of BR regimen in MZL patients in first line in daily clinical practice. The treatment schedule was rituximab at the dose of 375 mg/m on day 1 of each cycle and bendamustine at the dose of 90 mg/m on day 2 and 3, every 28 days for a maximum of 6 cycles. We analyzed 65 MZL patients (28 extranodal [EMZL], 23 splenic [SMZL], and 14 nodal [NMZL]) who underwent BR regimen as first line treatment. The median time from diagnosis to therapy was 2.5 months. Final responses were: 38 complete response (CR, 58.5%), 20 partial response and 7 progressive disease, leading to an overall response rate (ORR) of 89.2%. With respect to the histology, the ORR was 89.3% for EMZL, 82.6% for SMZL and 100% for NMZL, respectively (difference not statistically significant). With a median follow-up time of 44.6 months (range, 3.3-175.0 months), 2 (one EMZL after 42 months and one SMZL after 10 months) of 38 (5.2%) CR patients had disease relapse, yielding an estimated disease free survival of 89.2% at 61.1 months. The estimated 6-year progression free survival was 71.8% with 15 relapsed/progressed patients showing lymphoma recurrence within 48 months from end of treatment. The most frequently reported adverse events (any grade) were neutropenia (N = 35, 53.8%), fatigue (N = 15, 23.0%), and nausea (N = 12, 18.4%). All toxicities quickly resolved and no treatment-related death occurred. The BR regimen is effective and feasible in MZL patients inducing prolonged disease control with manageable toxicities.

Finalization of autologous stem cell transplant in complex and multirelapsed follicular lymphoma.

Tumori 2020 Dec 22;106(6):NP5-NP8. Epub 2020 May 22.

Institute of Haematology "L. e A. Seràgnoli," University of Bologna, Bologna, Italy.

Background: Follicular lymphoma (FL) is characterized by frequent relapses and need for multitude lines of therapy, which includes different immunochemotherapy regimens, novel monoclonal antibodies, novel drugs, and autologous or allogenic stem cell transplant. Early use of autologous stem cell transplantation (ASCT) improves prognosis in patients with FL who may be candidates for an aggressive approach.

Case Presentation: We report the case of a 49-year-old woman with thrombophilia with relapsed/refractory grade 3A FL, heavily pretreated, who achieved third complete remission after high-dose chemotherapy and ASCT, despite experiencing life-threatening adverse events during her treatment history.

Conclusions: Stem cell transplantation has emerged as the standard of care for young patients with FL but may be effective also in complex and multirelapsed clinical cases.

Chronic lymphocytic leukemia focus in the context of a cardiac mass in a pretreated patient: an exceptional incidental finding.

Tumori 2020 Dec 12;106(6):NP29-NP32. Epub 2020 Mar 12.

Institute of Haematology "L. e A. Seràgnoli," University of Bologna, Bologna, Italy.

Background: B-cell chronic lymphocytic leukemia (B-CLL) is a lymphoproliferative disorder consisting of clonal proliferation and accumulation of small, mature, CD5-positive B-lymphocytes in the blood, bone marrow, and lymphoid tissues. Among extranodal localizations, cardiac involvement is extremely rare: to our knowledge, there are no findings reported in the literature of concomitant B-CLL diagnosis in the context of atrial myxoma (so-called collision tumours) and the best strategy to treat these malignancies is unclear.

Case Report: We report the case of a 67-year-old woman diagnosed with B-CLL and atrial myxoma. Our patient was cardiologically symptomless and the cardiac mass was an incidental finding. The cardiac tumor appeared several years after B-CLL diagnosis. Histologic examination of the cardiac mass, removed in the suspicion of an atrial myxoma, revealed a lymphoid focus of B-CLL. The patient underwent surgery and subsequent systemic therapy for B-CLL.

Conclusions: The concomitant presence of B-CLL in the context of an atrial myxoma is extremely rare. The best strategy to treat these cardiac hematologic malignancies is unclear.

mutations and disruptions are poor prognostic biomarkers in mantle cell lymphoma receiving high-dose therapy: a FIL study.

Haematologica 2020 06 19;105(6):1604-1612. Epub 2019 Sep 19.

Division of Hematology, Department of Translational Medicine, University of Eastern Piedmont, Novara, Italy.

In recent years, the outcome of mantle cell lymphoma (MCL) has improved, especially in younger patients, receiving cytarabine-containing chemoimmunotherapy and autologous stem cell transplantation. Nevertheless, a proportion of MCL patients still experience early failure. To identify biomarkers anticipating failure of intensive chemotherapy in MCL, we performed target resequencing and DNA profiling of purified tumor samples collected from patients enrolled in the prospective (high-dose chemoimmunotherapy followed by autologous transplantation and randomized lenalidomide maintenance). Mutations of and disruption of by deletion or mutation associated with an increased risk of progression and death, both in univariate and multivariate analysis. By adding mutations and disruption to the MIPI-c backbone, we derived a new prognostic index, the "MIPI-genetic" ("MIPI- g"). The "MIPI-g" improved the model discrimination ability compared to the MIPI-c alone, defining three risk groups: i) low-risk patients (4-year progression free survival and overall survival of 72.0% and 94.5%); ii) inter-mediate-risk patients (4-year progression free survival and overall survival of 42.2% and 65.8%) and iii) high-risk patients (4-year progression free survival and overall survival of 11.5% and 44.9%). Our results: i) confirm that disruption identifies a high-risk population characterized by poor sensitivity to conventional or intensified chemotherapy; ii) provide the pivotal evidence that patients harboring mutations share the same poor outcome as patients harboring disruption; and iii) allow to develop a tool for the identification of high-risk MCL patients for whom novel therapeutic strategies need to be investigated.

V600E-positive monomorphic epitheliotropic intestinal T-cell lymphoma complicating the course of hairy cell leukemia.

Onco Targets Ther 2019 20;12:4807-4812. Epub 2019 Jun 20.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

Hairy cell leukemia (HCL) is an uncommon B-cell chronic lymphoproliferative disorder whose pathogenesis and recurrence are strictly dependent on the presence of the BRAF V600E mutant. A 65-year-old male presented a monomorphic epitheliotropic intestinal T-cell lymphoma (formerly enteropathy-associated T-cell lymphoma, type II) with HCL not responding to first-line induction with cladribine. The intestinal lymphoma bears the BRAF V600E mutant, which is the molecular hallmark of HCL, being implicated in its pathogenesis. The case is of interest, as it provides the first description of a V600E-positive intestinal T-cell lymphoma, along with immunohistochemical and molecular demonstration, occurring in concomitance with HCL. A novel digital PCR-base method for HCL disease assessment is also suggested.

Role of 18F-FLT PET/CT in suspected recurrent or residual lymphoma: final results of a pilot prospective trial.

Eur J Nucl Med Mol Imaging 2019 Jul 17;46(8):1661-1671. Epub 2019 May 17.

Nuclear Medicine, Azienda Ospedaliero-Universitaria di Bologna, Policlinico S.Orsola-Malpighi, Via Albertoni 15, 40138, Bologna (BO), Italy.

Purpose: To evaluate the role of F-18-Fluorothymidine (FLT) PET/CT in lymphoma patients with suspected recurrent or residual disease.

Methods: Adult lymphoma patients presenting with positive or equivocal F-18-FDG PET/CT at end-treatment or follow-up were prospectively addressed to an additional F-18-FLT-PET/CT. SUV max and tumour-to-background ratios (TBRs) were recorded for the most avid lesion. Biopsy or, when not available, clinical or imaging assessment were employed as standard of reference.

Results: Overall 52 patients were recruited. Histology was available in 20/52 patients (38%), proliferation-index (Ki-67) in 14/20. Disease was excluded in 13/52 patients (25%) (one reactive follicular hyperplasia, five reactive-inflammatory tissues, four reactive nodes, two nodal sarcoid-like and one non-specific peri-caecal finding). FDG and FLT scans were concordant in disease restaging in 34/52 patients (65%), whereas in 18/52 cases (35%) relevant discrepancies were recorded. SUV max and TBR were significantly higher in the disease versus the disease-free group, with both tracers (p = 0.0231 and 0.0219 for FDG; p = 0.0008 and 0.0016 for FLT). FLT-SUVmax demonstrated slightly better performance in discriminating benign from malignant lesions (ROC-AUC: 0.8116 and 0.7949 for FLT-SUV max and TBR; 0.7120 and 0.7140 for FDG). Optimal FLT-SUV max cut-offs were searched: three would lead to 95% sensitivity, 81% accuracy, and 39% specificity, whereas seven led to 100%, 41%, and 56% respectively. No statistically significant correlation was observed between the two FLT indices and Ki-67.

Conclusions: According to our results in a clinical setting of recurrent or residual lymphoma, FLT is not significantly superior to FDG and it is unlikely that it will be employed independently. FLT may be restricted to a few specific cases, as complementary to standard FDG imaging, to confirm a diagnosis or to define a better target to biopsy. However, due to FLT suboptimal performance, many findings would remain inconclusive, requiring further diagnostic procedures and reducing the effectiveness of performing an additional FLT scan.

A case report of the long treatment experience of a Sézary syndrome responder patient: 16 years through all the systemic and innovative therapies.

Hematol Oncol 2019 Apr 30;37(2):202-204. Epub 2019 Jan 30.

Institute of Hematology "L. e A. Seràgnoli,", University of Bologna, Bologna, Italy.

Existing therapies for Sézary syndrome (SS) are limited in efficacy and in disease control, and patients have very poor prognosis. Here, we report a case report of a patient who has a 16-year history of SS and related treatments (both standard and experimental). In particular, two drugs, one conventional (gemcitabine) and one experimental (mogamulizumab), were able to induce long lasting response. Patient refused to undergo allogeneic stem cell transplantation. After eleven lines of therapeutic approaches, the patient is in very good partial response and free of therapy at the latest available follow-up.

A patient with plasmablastic lymphoma achieving long-term complete remission after thalidomide-dexamethasone induction and double autologous stem cell transplantation: a case report.

BMC Cancer 2018 Jun 8;18(1):645. Epub 2018 Jun 8.

Institute of Haematology "L. e A. Seràgnoli", University of Bologna, Via Massarenti, 9 -40138, Bologna, Italy.

Background: No standard of care is established for plasmablastic lymphoma (PBL) and prognosis remains extremely poor, given that patients relapse early after chemotherapy and display resistance to commonly applied cytostatic drugs.

Case Presentation: We report a case of nodal, HIV-unrelated PBL in a patient who achieved and maintained a very long lasting complete remission after an intensive therapy consisting consisting of thalidomide plus dexamethasone followed by a consolidation with double autologous stem cell transplantation. Our approach was based on the full application of a standard multiple myeloma treatment and, to the best of our knowledge, it represents the only reported experience so far. This treatment was overall well tolerated.

Conclusions: Multiple myeloma-like treatment may represent a possible alternative to intensive lymphoma-directed therapies.

Lenalidomide in Pretreated Mantle Cell Lymphoma Patients: An Italian Observational Multicenter Retrospective Study in Daily Clinical Practice (the Lenamant Study).

Oncologist 2018 09 19;23(9):1033-1038. Epub 2018 Apr 19.

Institute of Hematology, University of Bologna, Bologna, Italy

Background: Mantle cell lymphoma (MCL) has the worst prognosis of B-cell subtypes owing to its aggressive clinical disease course and incurability with standard chemo-immunotherapy. Options for relapsed MCL are limited, although several single agents have been studied. Lenalidomide is available in Italy for patients with MCL based on a local disposition of the Italian Drug Agency.

Subjects, Materials, And Methods: An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on effectiveness and safety of lenalidomide use in real practice.

Results: Seventy patients received lenalidomide for 21/28 days with a median of eight cycles. At the end of therapy, there were 22 complete responses (31.4%), 11 partial responses, 6 stable diseases, and 31 progressions, with an overall response rate of 47.1%. Eighteen patients (22.9%) received lenalidomide in combination with either dexamethasone ( = 13) or rituximab ( = 5). Median overall survival (OS) was reached at 33 months and median disease-free survival (DFS) at 20 months: 14/22 patients are in continuous complete response with a median of 26 months. Patients who received lenalidomide alone were compared with patients who received lenalidomide in combination: OS and DFS did not differ. Progression-free survivals are significantly different: at 56 months, 36% in the combination group versus 13% in patients who received lenalidomide alone. Toxicities were manageable, even if 17 of them led to an early drug discontinuation.

Conclusion: Lenalidomide therapy for relapsed MCL patients is effective and tolerable even in a real-life context.

Implication For Practice: Several factors influence treatment choice in relapsed/refractory mantle cell lymphoma (rrMCL), and the therapeutic scenario is continuously evolving. In fact, rrMCL became the first lymphoma for which four novel agents have been approved: temsirolimus, lenalidomide, ibrutinib, and bortezomib. The rrMCL therapeutic algorithm is not so well established because data in the everyday clinical practice are still poor. Lenalidomide for rrMCL patients is effective and tolerable even in a real-life context.

Italian real life experience with brentuximab vedotin: results of a large observational study on 234 relapsed/refractory Hodgkin's lymphoma.

Oncotarget 2017 Oct 23;8(53):91703-91710. Epub 2017 May 23.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

A large Italian multicenter observational retrospective study was conducted on the use of brentuximab vedotin (BV) for patients with relapsed Hodgkin's lymphoma (HL) to check if clinical trial results are confirmed even in a real life context. 234 CD30+ HL patients were enrolled. Best response was observed after a median of 4 cycles in 140 patients (59.8%): 74 (31.6%) patients obtained a complete response (CR) and 66 (28.2%) achieved a partial response (PR); overall response rate at the end of the treatment was 48.3% (62 CR and 51 PR). The best response rate was higher in the elderly subset: 14 (50%) CR and 5 (17.8%) PR. Disease free survival was 26.3% at 3 years and progression free survival 31.9% at 4.5 years. Duration of response did not differ for who achieved at least PR and then either did or did not undergo consolidative transplant. Overall, the treatment was well tolerated and no death has been linked to BV-induced toxicity. Our report confirms activity in elderly patients, duration of response unrelated to the consolidation with transplant procedure, the relevance of the CR status at first restaging, and the role of BV as a bridge to transplant for chemorefractory patients.

Italian real-life experience with brentuximab vedotin: results of a large observational study of 40 cases of relapsed/refractory systemic anaplastic large cell lymphoma.

Between November 2012 and July 2014, in accordance with national law 648/96, brentuximab vedotin was available in Italy for patients with relapsed systemic anaplastic large cell lymphoma outside a clinical trial context. A large Italian observational retrospective study was conducted on the use of brentuximab vedotin in everyday clinical practice to check whether clinical trial results are confirmed in a real-life context. The primary endpoint of this study was best response; secondary endpoints were the overall response rate at the end of the treatment, duration of response, survival and safety profile. A total of 40 heavily pretreated patients were enrolled. Best response was observed after a median of four cycles in 77.5%: globally, 47.5% patients obtained a complete response, 64.2% in the elderly subset. The overall response rate was 62.5%. At the latest follow up, 15/18 patients are still in complete remission (3 with consolidation). The progression-free survival rate at 24 months was 39.1% and the disease-free survival rate at the same time was 54% (median not reached). All the long-term responders were aged <30 years at first infusion. The treatment was well tolerated even in this real-life context and no deaths were linked to drug toxicity. Brentuximab vedotin induces clinical responses quite rapidly, i.e. within the first four cycles of treatment in most responders, thus enabling timely use of transplantation. For patients ineligible for transplant or for those in whom a transplant procedure failed, brentuximab vedotin may represent a feasible effective therapeutic option in everyday clinical practice.

The treatment of primary mediastinal large B-cell lymphoma: a two decades monocentric experience with 98 patients.

BMC Cancer 2017 04 17;17(1):276. Epub 2017 Apr 17.

Institute of Haematology "L. e A. Seràgnoli", University of Bologna, Via Massarenti, 9 - 40138, Bologna, Italy.

Background: The purpose of this study is to investigate the most suitable first-line approach and the best combination treatment for primary mediastinal large B-cell lymphoma (PMLBCL) as they have been matter of debate for at least two decades.

Methods: Our single centre experience in the treatment of 98 de novo PMLBCL patients over the last 20 years is reviewed. All patients received MACOP-B chemotherapy. Thirty-seven received both rituximab and mediastinal radiotherapy; 30 were irradiated after chemotherapy, although not receiving rituximab and 20 received rituximab without radiotherapy consolidation. Eleven patients received chemotherapy only.

Results: Sixty-one (62.2%) patients achieved a complete response after MACOP-B (with or without rituximab); among the 27 (27.6%) partial responders, 21 obtained a complete response after radiotherapy. At the end of their scheduled treatment, 82 patients (83.7%) had a complete and 6 a partial response (6.1%). Eleven patients relapsed within the first 2 years of follow-up. The 17-year overall survival is 72.0% (15 patients died); progression-free and disease-free survival are 67.6% and 88.4%, respectively. A statistically significant difference in overall and progression-free survival was noted among treatment groups, although no disease-free survival difference was documented.

Conclusions: Our data indicate that a third-generation regimen like MACOP-B could be considered a suitable first-line treatment. Mediastinal consolidation radiotherapy impacts on survival and complete response rates and remains a good strategy to convert partial into complete responses. Data suggest that radiotherapy may be avoided in patients obtaining a complete response after (immuno)chemotherapy, but this requires confirmation with further ad hoc studies.

Efficacy and safety of biosimilar epoetin alpha in patients with chronic lymphoid neoplasms and chemotherapy-induced anaemia: An observational, retrospective, monocentric analysis.

Hematol Oncol 2018 Feb 23;36(1):136-143. Epub 2017 Mar 23.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

Epoetin biosimilars are an alternative to originator erythropoietic agents in the treatment of chemotherapy-induced anaemia; however, their effects in patients with lymphoproliferative disorders remain unclear. This analysis examined the response of patients with lymphoproliferative disorders experiencing chemotherapy-induced anaemia to 4- or 8-week treatment with the biosimilar epoetin alpha. Treatment was initiated at first occurrence of haemoglobin (Hb) < 10 g/dL during chemotherapy and was stopped when Hb was >11 g/dL, when chemotherapy was completed, or in case of transfusion dependency. Response to epoetin alpha was defined as an increase in Hb of >1 g/dL or as an Hb > 11 g/dL. Stability was defined as change in Hb of ±1 g/dL, and no response was indicated by a decrease in Hb of >1 g/dL or acquired transfusion dependence. Overall, 65 patients were enrolled (median age 69 years; 47.7% ≥ 70 years old). Mean Hb levels at the initiation of epoetin alpha was 9.3 ± 0.5 g/dL. Mean Hb levels reached 10.7 ± 1.4 and 10.6 ± 1.5 g/dL at weeks 4 and 8, respectively, in patients on first-line chemotherapy and 11.4 ± 1.6 and 9.7 ± 1.3 g/dL in those on a second- or higher-line regimen. Overall, 70.8% of patients responded, 26.1% had stable Hb, and 3.1% did not respond. Delays or interruption of any chemotherapy cycle due to anaemia occurred in 18 patients. The biosimilar epoetin alpha was well tolerated and allowed patients with non-Hodgkin lymphoma or chronic lymphoproliferative disorders to continue their course of chemotherapy by effectively increasing and maintaining adequate concentrations of Hb.

Two cases of primary vitreoretinal lymphoma: a diagnostic challenge : The supporting role of multimodal imaging in the diagnosis of primary vitreoretinal lymphoma.

Int Ophthalmol 2018 Feb 30;38(1):353-361. Epub 2016 Dec 30.

Ophthalmology Unit, S. Orsola-Malpighi Hospital, University of Bologna, via Pelagio Palagi 9, 40138, Bologna, Italy.

Purpose: To report two cases of primary vitreoretinal lymphoma (PVRL), which presented as intermediate and posterior uveitis.

Methods: Combined clinical assessment, multimodal imaging with spectral-domain optical coherence tomography, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, brain magnetic resonance imaging and vitreous and retinal biopsy. Case 1 was a 48-year-old woman who complained of visual loss in her right eye secondary to a diffuse vitreous opacification and multiple chorioretinal lesions. Case 2, a 74-year-old man, presented with low vision in his right eye due to a wide chorioretinal lesion at the posterior pole, vitreous opacification and posterior uveitis in both eyes.

Results: Diffuse large B cell lymphoma was histologically diagnosed in the cerebellum in the first case and in chorioretinal tissue in the second patient. Atypical lymphoid cells were detected and allowed to make a diagnosis of primary central nervous system lymphoma in case 1 and PVRL in case 2.

Conclusion: PVRL often masquerades ad intermediate or posterior uveitis. The management of the patients needed a team of pathologists, haematologists and ophthalmologists to achieve the correct diagnosis and choose the more appropriate therapy. Some peculiar characteristics on multimodal imaging, even in atypical cases of PVRL, should raise suspicious for PVRL and lead to a diagnostic vitrectomy and/or retinal biopsy.

Long-Term Responders After Brentuximab Vedotin: Single-Center Experience on Relapsed and Refractory Hodgkin Lymphoma and Anaplastic Large Cell Lymphoma Patients.

Oncologist 2016 12 2;21(12):1436-1441. Epub 2016 Aug 2.

Institute of Hematology "L. e A. Seràgnoli," University of Bologna, Bologna, Italy

Background: Brentuximab vedotin (BV) has shown high overall response rate in refractory/relapsed Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (sALCL) with reported long-term response duration in clinical trials, but few data are available regarding its role in long-term outcomes in real life.

Patients And Methods: A single-center observational study was conducted on patients treated with BV in daily clinical practice to evaluate the long-term effectiveness of BV in HL and sALCL patients and to check whether clinical trial results are confirmed in a real-life context.

Results: The best response rate in the treated 53 patients (43 HL and 10 sALCL) was 69.8% (with 46.5% complete response [CR]) in HL and 100% (80% CR) for sALCL, respectively. With a median patient follow-up of 36.8 months, the estimated median duration of response was 31.5 months for HL and 17.8 for sALCL, respectively. At the latest available follow-up, 75% of patients were still in response, with 43% without any consolidation. Toxicity was primarily neurological and it was rarely so serious to require dose reduction or interruption. In addition, it always reversed completely after the end of treatment.

Conclusion: Our data showed that 51% of patients treated with BV can be regarded as "long-term responders." Among these cases, for all patients who underwent stem cell transplantation immediately after BV, the procedure was consolidative. For patients who have remained in continuous CR without any consolidation after therapy, BV can induce prolonged disease control.

Implications For Practice: Brentuximab vedotin (BV) has shown a high overall response rate in refractory/relapsed Hodgkin lymphoma and systemic anaplastic large cell lymphoma, with reported long-term response duration in clinical trials, whereas few data are available regarding its role in long-term outcomes in real life. The data reported in this study suggest that BV can induce the same results in daily clinical practice. The data showed that 51% of patients treated with BV can be regarded as "long-term responders." Among these cases, BV can induce prolonged disease control in patients who have remained in continuous complete response without any consolidation after the drug.

90-yttrium-ibritumomab tiuxetan consolidation of fludarabine, mitoxantrone, rituximab in intermediate/high-risk follicular lymphoma: updated long-term results after a median follow-up of 7 years.

Cancer Med 2016 Jun 14;5(6):1093-7. Epub 2016 Mar 14.

Institute of Hematology "L. e A. Seràgnoli", University of Bologna, Bologna, Italy.

Radioimmunotherapy (RIT) after an induction phase with conventional chemoimmunotherapy became an attractive strategy of consolidation for patients with advanced follicular lymphoma: in particular, in many studies RIT was represented by yttrium-90-ibritumomab tiuxetan ((90) Y-IT). Independently by the different front-line treatment, updates on the long-term follow-up of these studies are needed because the disease course of follicular lymphoma is characterised by multiple relapses and progressively shorter durations of response. We report updated long-term efficacy and toxicity results of a multicenter phase II study on sequential treatment with four cycles of fludarabine, mitoxantrone, and rituximab followed by (90) Y-IT as front-line therapy for untreated patients with intermediate/high-risk follicular lymphoma. With a median follow-up of 84 months, only 19/49 (38.8%) complete response patients relapsed, yielding an estimated long-term disease-free survival of 62.6%. The 7-year overall survival was 72.7%. Four (7.3%) second acute myeloid leukemia occurred, with a median time following RIT of 42 months. A relevant patients' responsiveness to subsequent therapies occurred: approximately 65% of relapsed patients obtained a good clinical response after the second-line treatment. These data represented the first evidence of a real role even in the long period of 90Y-IT after a fludarabine-containing regimen plus rituximab in the treatment of high-risk follicular lymphoma.

High efficacy of the MACOP-B regimen in the treatment of adult Langerhans cell histiocytosis, a 20 year experience.

BMC Cancer 2015 Nov 9;15:879. Epub 2015 Nov 9.

Department of Experimental, Diagnostic and Specialty Medicine- DIMES, Institute of Hematology and Medical Oncology L.A. Seragnoli, University of Bologna, Via Massarenti 9, 40138, Bologna, Italy.

Background: Adult Langerhans cell histiocytosis (LCH) is an orphan disease. Chemotherapy is usually reserved to patients presenting with single system multifocal (SS-m) or multisystem (MS) disease but due to the lack of randomized studies no standard first line therapy has been defined yet. Pediatric regimens based on the vinblastine/prednisone backbone are not well tolerated in adults and probably less effective. We previously demonstrated high efficacy of the dose dense polichemotherapy regimen MACOP-B in 7 adult patients with SS-m or MS-LCH, in terms of high response rate and durable responses. Here we report an update of these data with the purpose of evaluating the long term efficacy of MACOP-B in adult LCH.

Methods: Clinical data of all adult LCH patients (n = 17) diagnosed and treated at our Institution during the past 20-year period were retrospectively reviewed.

Results: A total of 11 patients (6 with SS-m and 5 with MS-LCH) were treated with MACOP-B from 1995 to 2014. The overall response rate was confirmed to be 100 %, with a complete response of 73 % and a partial response rate of 27 %. Overall progression free survival was 64 %, and disease free survival after achievement of initial CR was 87 %. Overall survival rate was 82 % after 6.7 years of median follow-up.

Conclusions: These data confirm high activity of MACOP-B in adult LCH, indicating that a substantial fraction of patients achieve long lasting responses and can be cured with this therapeutic approach.
