RESUMEN
An endobronchial localization of Hodgkin lymphoma is rare, and few experiences since the 1900s have been reported in the literature. Here we report the first case of a relapsed/refractory Hodgkin lymphoma with a critical vegetative mass at the level of the trachea successfully treated with pembrolizumab.

Mycosis fungoides (MF) is a disease almost impossible to cure. In the context of heavily pretreated patients, the anti-programmed cell death protein 1 (anti-PD-1) pembrolizumab is a valid therapeutic option. The alteration of the PD-1-PD ligand 1 (PD-L1) axis is often present in MF, and this aspect explains the feasibility of this therapy. We report the case of a 60-year-old woman diagnosed with MF in 2003, Olsen stage IA (T1M0NXBO). Since the moment of the diagnosis, she received 10 lines of therapy, with a short duration of response after each one of them. In April 2020, our patient started pembrolizumab 2 mg/kg every 3 weeks, and she achieved a partial response after the 4th cycle, consistent with the modified severity assessment tool (mSWAT) 1, which she is still maintaining after 10 cycles. No grade ≥3 adverse events were recorded. We conclude that pembrolizumab can induce extremely rapid responses in MF, with very low toxicity.

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.

The treatment of hairy cell leukemia (HCL) has considerably changed over years. Purine analogues, namely cladribine, now represent the treatment of choice. One hundred and eighty-four patients were followed between 1986 and 2018 and treated according to era-specific guidelines. Responses were classified by combining Consensus Resolution criteria and marrow immunohistochemistry. Patients were grouped according to the number of treatment lines they received. Patients treated first line responded in 86% of cases, with complete response (CR) in 44% of cases. Response rates remained high throughout the first four lines (84%, 81%, 79% for the second line onward, with CR in 38%, 37%, 15% of cases respectively). One hundred and twenty-two patients received cladribine as first line treatment, with a response rate of 86% and a CR rate of 54%. Among the 66 CR patients, 45 (68%) have never received further therapy: 11 patients are in continuous CR between 5 and 10 years after treatment, 14 between 10 and 20 years and three patients at more than 20 years. Median time-to-next treatment (TTNT) for frontline cladribine-treated patients was 8.2 years: partial responders had a significantly shorter median TTNT than CR patients (5.3 years vs median not reached at 25.8 years, p < 0.001). Patients with HCL require subsequent lines of therapy in more than 50% of cases. Purine analogues allow significant response rates when applied first line and upon retreatment. Some patients may enjoy long lasting treatment-free intervals after one course of cladribine.

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/m2 on day 1 of each cycle and bendamustine at the dose of 90 mg/m2 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.

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.

PURPOSE: One of the most critical issues in the management of Hodgkin lymphoma (HL) patients who resulted as primary relapsed or refractory is to obtain a minimal disease status before autologous stem cell transplantation (ASCT). Finding a salvage regimen able to induce this status without severe toxicity would represent a major achievement in this setting. METHODS: A single-center retrospective study was conducted to assess effectiveness and safety of BEGEV (bendamustine, gemcitabine, and vinorelbine) regimen as first salvage setting prior to ASCT in HL patients. RESULTS: Forty-three patients were treated in our institution between October 2017 and November 2020. Median age at BEGEV therapy was 35.0 years (range 17.2- 70.0), and the median time from frontline therapy to the first cycle of BEGEV was 79.5 days (range 4-2267). At the end of treatment, 31 patients achieved a complete response (CR), with an overall response rate of 76.7%. Forty-one patients harvested CD34+ cells and 35/43 (81.4%) patients underwent ASCT. With a median follow-up of 22 months, 4 CR patients had disease relapse, yielding an estimated disease-free survival of 73.9% at 34 months. The estimated 2-year progression-free survival was 66.7%. Response to first-line chemotherapy did not significantly influence prognosis. CONCLUSIONS: BEGEV regimen was well tolerated, and reversible haematological toxic effects were the most common adverse events. Real-life data on BEGEV regimen as first salvage setting showed a relevant rate of objective responses and a limited myelotoxicity with no impairment of a subsequent mobilization of peripheral blood stem cells.

The follow-up of the pivotal trial and large case series reports of a proportion of patients, between 5% and 9%, with relapsed or refractory Hodgkin lymphoma failing autologous stem cell transplantation and treated with brentuximab vedotin, achieving and maintaining long lasting complete responses with no further treatment. Very long-term data on the outcomes of such patients are indeed underreported. Our institutional experience with patients meeting these characteristics and in continuous complete response for more than 5 years after brentuximab vedotin was reviewed. Five patients achieved a median duration of complete response of 7.4 (range 5.1-8.1) years, and none of them encountered disease relapse or received any subsequent consolidation, including allogeneic transplantation. A proportion of patients failing autologous transplantation and receiving subsequent brentuximab vedotin may reach a long-lasting complete response with no need of further treatment. These patients are therefore considered cured. The role of allogeneic transplantation in such patients is matter of debate.

Background: T cells engineered to target CD19 antigen on neoplastic B cells represent the most striking example of CAR-T cell therapy. The success rate of this therapy is affected by several limitations: target antigen loss, and/or acquisition of a senescent/exhausted phenotype by CAR and non-CAR T cells. Case presentation: We report on a patient affected by refractory Diffuse Large B-cell Lymphoma who was resistant to CAR T-cell therapy and to two cycles post CAR-T of pembrolizumab (PBZ) due to the evolution into a B-cell Hodgkin-like lymphoma. Owing to the CD30 expression and the Hodgkin-like phenotype, the patient was ultimately treated with Brentuximab-Vedotin and finally underwent remission. Upon PBZ treatment, 100% of circulating CAR-T+ cells showed a persistent CD8+ senescent/exhausted phenotype, while an increase in the percentage of senescent cells was found in the non-CAR CD8+ T cells compartment. Conclusions: PBZ is not able to reinvigorate exhausted CAR+ T cells and to confer durable clinical response. We hypothesize that the phenomenon is due to the senescent phenotype of CAR+ T cells, which did not allow PBZ-induced reactivation and proliferative rescue. The phenomenon, together with the loss of CAR-T target CD19 and the shift of non-CAR CD8+ T cells towards a senescent phenotype likely contributed to set up an immune landscape with poor antitumor capacity.

OBJECTIVE: Peripheral T-cell lymphomas (PTCLs) are a group of heterogeneous T-cell malignancies representing 5%-10% of aggressive lymphomas. The prognosis is poor for patients with relapsed/refractory (R/R) disease, with a median overall survival of less than 6 months and no standardized treatments. We discuss the role of the phosphatidylinositol 3-kinase (PI3K) γδ inhibitor duvelisib as bridge to allotransplantation in a patient with R/R PTCL. METHODS: Case report. RESULTS: A 55-year-old woman diagnosed with relapsed nodal PTCL with T-follicular helper phenotype received PI3K γδ inhibitor duvelisib in the context of the phase II PRIMO clinical trial. After two cycles at a dose of 75 mg twice daily, the patient achieved complete response (CR), which was subsequently consolidated with human leukocyte antigen fully matched unrelated donor allotransplantation. No major toxicities were recorded during the duvelisib treatment period or during hospitalization for allotransplantation. At the latest follow-up, the patient was alive and still in CR 10 months posttransplant. CONCLUSIONS: Duvelisib should be further explored as a bridge to allotransplantation in patients with R/R PTCL, given the success and low toxicity in our patient.

Large B-cell lymphomas (LBCL) are the most common types of non-Hodgkin lymphoma. Although outcomes have improved thanks to the introduction of rituximab-based chemoimmunotherapy, certain LBCL still represents a challenge because of initial resistance to therapy or recurrent relapses. Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are second-generation autologous CD19-targeted chimeric antigen receptor (CAR) T-cell therapies approved for patients with relapsed/refractory (R/R) LBCL, based on the results of phase II pivotal single-arm trials ZUMA-1 (for axi-cel) and JULIET (for tisa-cel). Here, we report patients outcomes with axi-cel and tisa-cel in the standard of care (SoC) setting for R/R LBCL, treated at our Institution. Data were collected from patients who underwent leukapheresis between August 2019 and February 2021. Toxicities were graded and managed according to the institution's guidelines. Responses were assessed as per Lugano 2014 classification. Of the 30 patients who underwent leukapheresis, 18 (60%) received axi-cel, while 12 (40%) tisa-cel. Grade 3 or higher cytokine release syndrome and neurotoxicity occurred in 10% and 16% patients, respectively. Best objective and complete response rates were 73.3% and 40%, respectively. Treatment in SoC setting with CD19 CAR T-cell therapies for R/R LBCL showed a manageable safety profile and high objective response rate.
RESUMEN
BACKGROUND: Sézary syndrome (SS) is a rare lymphoproliferative neoplasm, almost incurable outside the setting of allogeneic transplantable patients. The prognosis for relapsed/refractory patients remains poor, as the available drugs confer short-lasting remission. In this setting, the anti-chemokine receptor type 4 (CCR4) monoclonal antibody mogamulizumab demonstrated efficacy in an international, open-label, randomized controlled phase 3 trial (MAVORIC) versus vorinostat. CASE DESCRIPTION: A heavily pretreated 57-year-old SS woman (stage IVA) was randomized in the mogamulizumab arm of MAVORIC at our Institution. She quickly achieved a response, but after 30 cycles, she was discontinued from therapy due to cutaneous toxicity. Nevertheless, she is still in complete response (CR). CONCLUSIONS: mogamulizumab is an anti-CCR4 monoclonal antibody that can induce long-lasting response also in very heavily pretreated patients not responding to any previous treatment. The extraordinary characteristic of our patient is that she is still in CR after 2.5 years since treatment discontinuation.
RESUMEN
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.

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.
