RESUMEN
Hodgkin lymphoma (HL) is an uncommon malignancy of B-cell origin. Classical HL (cHL) and nodular lymphocyte-predominant HL are the 2 main types of HL. The cure rates for HL have increased so markedly with the advent of modern treatment options that overriding treatment considerations often relate to long-term toxicity. These NCCN Guidelines Insights discuss the recent updates to the NCCN Guidelines for HL focusing on (1) radiation therapy dose constraints in the management of patients with HL, and (2) the management of advanced-stage and relapsed or refractory cHL.

Doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with or without radiation is standard therapy for limited-stage Hodgkin lymphoma (HL) but carries risks of bleomycin-induced lung injury and radiation toxicity. Brentuximab vedotin is highly active in relapsed HL and was recently approved with doxorubicin, vinblastine, and dacarbazine (AVD) for previously untreated stage III/IV HL. We evaluated brentuximab-AVD for nonbulky stage I/II HL in a multicenter phase 2 study. Patients received a lead-in cycle of brentuximab vedotin monotherapy on days 1 and 15, followed by an exploratory positron emission tomography/computed tomography scan. Patients then received brentuximab-AVD for 4 to 6 cycles based on interim positron emission tomography/computed tomography scanning after cycle 2. Thirty-four patients were enrolled with a median age of 36 years (range, 20-75 years). Risk was early favorable in 62% and unfavorable in 38%. The best complete response rate was 100%. At a median follow-up of 38 months, the progression-free survival and overall survival were 94% and 97%, respectively. The most common adverse events were peripheral sensory neuropathy (79%), neutropenia (76%), fatigue (74%), and nausea (71%). The most common grade 3/4 toxicities were neutropenia (62%), febrile neutropenia (35%), and peripheral sensory neuropathy (24%). One elderly patient died of neutropenic sepsis in the first brentuximab-AVD cycle. Brentuximab dose reductions were required in 38% of patients, most for peripheral neuropathy. In conclusion, brentuximab-AVD without bleomycin or radiation produced a high complete response rate, with most patients requiring only 4 total cycles of therapy. Because toxicity was higher than would be expected from AVD alone, this method may not be appropriate for early-stage patients with a highly favorable prognosis. This trial was registered at www.clinicaltrials.gov as #NCT01534078.

The NCCN Clinical Practice Guidelines in Oncology for Hodgkin Lymphoma (HL) provide recommendations for the management of adult patients with HL. The NCCN panel meets at least annually to review comments from reviewers within their institutions, examine relevant data, and reevaluate and update their recommendations. Current management of classic HL involves initial treatment with chemotherapy alone or combined modality therapy followed by restaging with PET/CT to assess treatment response. Overall, the introduction of less toxic and more effective regimens has significantly advanced HL cure rates. This portion of the NCCN Guidelines focuses on the management of classic HL.

Several non-Hodgkin lymphoma (NHL) subtypes, including diffuse large B-cell lymphoma (DLBCL), variably express CD30. This phase 2, open-label study evaluated the efficacy of brentuximab vedotin, an anti-CD30 antibody-drug conjugate, in relapsed/refractory CD30(+) NHL. This planned subset analysis of B-cell NHLs includes 49 patients with DLBCL and 19 with other B-cell NHLs. Objective response rate was 44% for DLBCL, including 8 (17%) complete remissions (CRs) with a median duration of 16.6 months thus far (range, 2.7 to 22.7+ months). There was no statistical correlation between response and level of CD30 expression; however, all responding patients had quantifiable CD30 by computer-assisted assessment of immunohistochemistry. DLBCL patients were generally refractory to first-line (76%) and most recent therapies (82%), and 44% of these refractory patients responded (15% CRs). Patients with other B-cell lymphomas also responded: 1 CR, 2 partial responses (PRs) of 6 with gray zone, 1 CR of 6 with primary mediastinal B-cell, and 1 CR of 3 with posttransplant lymphoproliferative disorder. Adverse events were consistent with known toxicities. The combination of brentuximab vedotin with rituximab was generally well tolerated and had activity similar to brentuximab vedotin alone. Overall, significant activity with brentuximab vedotin was observed in relapsed/refractory DLBCL, and responses occurred across a range of CD30 expression. This study was registered at www.clinicaltrials.gov as #NCT01421667.

This portion of the NCCN Guidelines for Hodgkin lymphoma (HL) focuses on the management of classical HL. Current management of classical HL involves initial treatment with chemotherapy or combined modality therapy followed by restaging with PET/CT to assess treatment response using the Deauville criteria (5-point scale). The introduction of less toxic and more effective regimens has significantly advanced HL cure rates. However, long-term follow-up after completion of treatment is essential to determine potential long-term effects.

In a phase 1 trial, idelalisib (GS-1101, CAL-101), a selective inhibitor of the lipid kinase PI3Kδ, was evaluated in 54 patients with relapsed/refractory chronic lymphocytic leukemia (CLL) with adverse characteristics including bulky lymphadenopathy (80%), extensive prior therapy (median 5 [range 2-14] prior regimens), treatment-refractory disease (70%), unmutated IGHV (91%), and del17p and/or TP53 mutations (24%). Patients were treated at 6 dose levels of oral idelalisib (range 50-350 mg once or twice daily) and remained on continuous therapy while deriving clinical benefit. Idelalisib-mediated inhibition of PI3Kδ led to abrogation of Akt phosphorylation in patient CLL cells and significantly reduced serum levels of CLL-related chemokines. The most commonly observed grade ≥3 adverse events were pneumonia (20%), neutropenic fever (11%), and diarrhea (6%). Idelalisib treatment resulted in nodal responses in 81% of patients. The overall response rate was 72%, with 39% of patients meeting the criteria for partial response per IWCLL 2008 and 33% meeting the recently updated criteria of PR with treatment-induced lymphocytosis.(1,2) The median progression-free survival for all patients was 15.8 months. This study demonstrates the clinical utility of inhibiting the PI3Kδ pathway with idelalisib. Our findings support the further development of idelalisib in patients with CLL. These trials were registered at clinicaltrials.gov as #NCT00710528 and #NCT01090414.

Hodgkin lymphoma (HL) is an uncommon malignancy involving lymph nodes and the lymphatic system. Classical Hodgkin lymphoma (CHL) and nodular lymphocyte-predominant Hodgkin lymphoma are the 2 main types of HL. CHL accounts for most HL diagnosed in the Western countries. Chemotherapy or combined modality therapy, followed by restaging with PET/CT to assess treatment response using the Deauville criteria (5-point scale), is the standard initial treatment for patients with newly diagnosed CHL. Brentuximab vedotin, a CD30-directed antibody-drug conjugate, has produced encouraging results in the treatment of relapsed or refractory disease. The potential long-term effects of treatment remain an important consideration, and long-term follow-up is essential after completion of treatment.

Serum albumin (SA) has been shown to be a prognostic marker in many hematological malignancies and in diffuse large B-cell lymphoma (DLBCL) prior to chemo-immunotherapy. SA may be a surrogate for age, comorbid status, and disease severity. Here, we aimed to assess whether SA can be an independent prognostic marker in patients with newly diagnosed DLBCL treated with rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone (R-CHOP). Patients who presented at the Moffitt Cancer Center from 2007 to 2010 for DLBCL diagnosis or treatment were identified using our institutional database. Clinical and treatment data were recorded, including SA levels at diagnosis. Survival time was estimated using the Kaplan-Meier method, with Cox proportional hazard model used to identify potential risk factors for time-to-event data. From 295 identified patients, 171 were excluded for not having primary treatment at our institution or not having R-CHOP treatment. In 124 included patients (mean age at diagnosis of 58 years, 91 % Caucasian), 25 % were categorized as poor by the revised International Prognostic Index. Overall and progression-free survival at 4 years were 65 % (95 % CI 57-75) and 58 % (95 % CI 0.49-0.69), respectively. Using multivariate analysis, we found that the hazard index of death of patients with SA ≥3.7 g/dL was 26 % (95 % CI 13-53) of the hazard for those patients who had SA <3.7 g/dL when controlling for the revised International Prognostic Index risk and initial lymphocyte count. Our study shows that SA ≥3.7 g/dL is an independent prognostic marker in DLBCL patients treated with R-CHOP.

A 68-year-old woman with a history of follicular lymphoma had pathological findings of grade 3B follicular lymphoma, mantle cell lymphoma (MCL), and diffuse large B-cell lymphoma (DLBCL) identified in 1 lymph node. The DLBCL appeared to be a transformation of the follicular lymphoma. The nodules were diffusely and strongly positive for CD20, BCL6, and BCL2. CD43 highlighted smaller lymphocytes in a fraction of the nodules. BCL1 staining was variable with a mixture of nodular and mantle zone patterns. The diffuse areas showed weaker positivity for CD10, BCL2, and BCL6. CD3 and CD5 highlighted intermixed T cells. The Ki-67 proliferative index was overall estimated to be 60%. Fluorescent in situ hybridization performed on the lymph node was positive for CCND1/IGH. The patterns of BCL1 and BCL6 staining demonstrated 2 separate populations of neoplastic B lymphocytes.

Extranodal marginal zone lymphoma (EMZL) encompasses 70% of cases of marginal zone lymphoma. Frontline bendamustine and rituximab (BR) were derived from trials involving other indolent non-Hodgkin's lymphomas. Only one trial has evaluated frontline BR prospectively in EMZL. This retrospective study reports outcomes among EMZL patients receiving frontline BR. Twenty-five patients were included with a median age of 69 years (40-81). Five (20.0%) patients had stage I/II disease, and 20 (80.0%) had stage III/IV disease. The median number of cycles was 6.0 (3.0-6.0). Maintenance rituximab was administered to 10 (41.7%) individuals. Overall response rate (ORR) was 100.0% (60.0% complete response, 40.0% partial response). Medians of overall survival and progression-free survival were not reached. The estimated 2-year progression-free survival was 85.2% and overall survival was 100.0%. Four (16.6%) patients had infections related to treatment; 3 (12.0%) transformed to diffuse large B-cell lymphoma; 5 (20.8%) had a relapse or progression of EMZL; and 3 (12.0%) died unrelated to BR. BR is an efficacious and well-tolerated front-line regimen for EMZL with response data consistent with existing literature.

Nodal peripheral T cell lymphomas (PTCLs) are challenging subsets of non-Hodgkin lymphomas characterized by their heterogeneity and aggressive clinical behavior. Given the mixed outcomes reported in previous studies, the efficacy of autologous hematopoietic cell transplantation (auto-HCT) as a consolidation strategy following initial chemotherapy response remains uncertain. This study aims to evaluate the impact of upfront auto-HCT consolidation on overall survival (OS) and event-free survival (EFS) among patients with nodal PTCL who achieved a complete or partial response to initial chemotherapy. A retrospective cohort study was conducted at Moffitt Cancer Center, involving 123 patients with nodal PTCL treated between February 2005 and February 2021. Patients were stratified into 2 groups based on whether they received auto-HCT as part of their initial treatment strategy. Kaplan-Meier method and Cox proportional hazard models were used for statistical analysis to compare OS and EFS between groups. Patients undergoing auto-HCT after first response demonstrated significantly longer median OS (12.3 versus 4.3 yr; P = .035) and EFS (6.2 versus 2.2 yr; P = .003) compared to those who did not. Multivariate analyses indicated that auto-HCT at first response and younger age at diagnosis were favorable prognostic factors. The findings suggest that upfront auto-HCT consolidation can significantly improve long-term outcomes in patients with nodal PTCL, supporting the strategy of early auto-HCT consideration and referral following initial chemotherapy response. These results underscore the importance of integrating upfront auto-HCT into the treatment paradigm for nodal PTCL, emphasizing early referral to transplantation services to optimize patient outcomes.

BACKGROUND: Advancements in frontline therapy and chemotherapy-sparing treatments in chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have altered the treatment algorithms of this disease. We present a frontline alternative for treatment- naïve (TN) CLL/SLL patients. METHODS: This was a single-center, phase 2 study of high-dose methylprednisolone (HDMP) and ofatumumab with lenalidomide and ofatumumab consolidative therapy for all comers with TN CLL/SLL. Treatment was continued until disease progression or intolerable side effects. Patients were assessed for response per iwCLL 2008 criteria after completing cycles 3 and 12. RESULTS: Forty-five patients were enrolled (median age, 62.6 years). High-risk features included del17p (18%), Del11q (22%), and unmutated IGHV gene (76%). Median treatment duration was 32·2 (2·7-75·9) months. Thirty-six patients discontinued treatment due to disease progression (22%), adverse events (40%), allogeneic hematopoietic cell transplantation (allo-HCT) (7%), consent withdrawal (4%), and secondary malignancies (7%). The best overall and complete response rates were 96& and 29% respectively. At median follow-up of 61·7 (5·6-84·9) months, 9 patients remained on treatment. Median progression-free survival was 54·4 (2·9-77·6) months. Three patients underwent allo-HCT after a median of 3 (3-4) treatment cycles. Treatment was well tolerated, with a grade 3/4 infusion reaction in one patient. The most common grade 3/4 hematological adverse event was neutropenia (69%). Four patients had grade 3/4 infections. No grade 3/4 tumor flares, tumor lysis syndrome, or thrombosis were observed. CONCLUSION: The combination of ofatumumab, HDMP, and lenalidomide was effective and relatively well tolerated in treatment-naive CLL/SLL. Its role in the frontline setting remains unclear given the current available and effective treatment options. FUNDING: The funders had no role in the study.

INTRODUCTION: L-asparaginase-based chemotherapy regimens are effective for treating chemotherapy-resistant natural killer- (NK-) cell neoplasms. To treat these lymphoma subtypes in Asia, where NK/T-cell lymphomas are more prevalent, the NK-Cell Tumor Study Group developed the SMILE regimen, which includes a steroid, methotrexate, ifosfamide, L-asparaginase, and etoposide. In the US however, the only commercially available form of asparaginase is the pegylated form (PEG-asparaginase) which has been incorporated into a modified SMILE (mSMILE). We sought to study the toxicity associated with replacing L-asparaginase with PEG-asparaginase in mSMILE. PATIENTS AND METHODS: We retrospectively identified all adult patients treated with the mSMILE chemotherapy regimen in our database at Moffitt Cancer Center (MCC) between December 1, 2009, and July 30, 2021. Patients were included if they were treated with mSMILE irrespective of their underlying diagnosis. Toxicity was assessed using Common Terminology Criteria for Adverse Events (CTCAE) version 5. The rate of toxicity in our mSMILE treatment group was numerically compared to data published in a metanalysis of the SMILE regimen's toxicity (Pokrovsky et al., 2019). RESULTS: A total of 21 patients were treated with mSMILE at MCC during the 12-year analysis window. Compared to patients receiving the L-asparaginase-based SMILE, patients receiving mSMILE experienced grade 3 or 4 leukopenia less often, with a toxicity rate of 62% (median with SMILE, 85% [95% CI, 74%-95%]); thrombocytopenia, however, was more common, with a toxicity rate of 57% (median with SMILE, 48% [95% CI, 40%-55%]). Other hematological, hepatic and coagulation related toxicities were also reported. CONCLUSION: In a non-Asian population, the mSMILE regimen with PEG-asparaginase is a safe alternative to the L-asparaginase-based SMILE regimen. There is a comparable risk of hematological toxicity, and no treatment-related mortality was seen in our population.

ABVD (Adriamycin, bleomycin, vinblastine, dacarbazine) with or without radiation has been the standard treatment for limited-stage Hodgkin lymphoma (HL) but carries risks of bleomycin lung injury and radiation toxicity. Brentuximab vedotin (BV) is approved with AVD for stage III-IV HL, but carries increased risks of peripheral neuropathy (PN) and neutropenic fever, likely due to overlapping toxicity between BV and vinblastine. We therefore evaluated BV in combination with AD for 4 or 6 cycles based on interim positron emission tomography response. Thirty-four patients with nonbulky stage I-II HL were enrolled. Risk was early favorable in 53% and unfavorable in 47%. The overall and complete response rates (CRRs) were 100% and 97%, respectively, with a 5-year progression-free survival (PFS) of 91%. No differences in outcome were observed based on stage (I vs II) or risk status (early favorable vs unfavorable). The most common adverse events were nausea (85%), peripheral sensory neuropathy (59%), and fatigue (56%). There were no cases of grade-4 neutropenia or neutropenic fever, and no patient received granulocyte-colony stimulating factor. Most cases of PN were grade 1, and no patient experienced grade ≥3 PN. BV-AD produced a high CRR and durable PFS with most patients requiring 4 cycles of therapy. Compared with BV-AVD, the toxicity profile appeared improved, with predominantly grade 1 reversible PN and no case of grade 4 neutropenia or neutropenic fever. This regimen warrants further study in HL and may serve as a backbone for the addition of novel agents. This trial is registered on clinicaltrials.gov (NCT02505269).

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Hodgkin Lymphoma (HL) include the clinical management of classical HL and lymphocyte-predominant HL (LPHL). Major changes have been incorporated into these guidelines since their inception. In the 2012 NCCN Guidelines for HL, PET scans are not recommended for interim restaging of patients with stage I to II favorable disease. After reevaluating the available evidence on the use of interim PET imaging, the panel recommends the use of diagnostic CT scan of involved sites for interim restaging after completion of chemotherapy for this group of patients. Maintenance rituximab for 2 years is included as an option for patients with stage IB to IIB or stage III to IV LPHL treated with rituximab alone in the first-line setting. Brentuximab vedotin is included as an option for patients with progressive disease or relapsed disease after second-line chemotherapy or high-dose therapy with autologous stem cell rescue.

BACKGROUND: Follicular lymphomas (FLs) are a heterogeneous group of lymphomas. No standard of care exists, and the management of these patients is highly individualized. METHODS: After reviewing the scientific literature pertaining to the prognosis and management of FLs, we describe recent developments in treatment and discuss future trends in the care of patients with this disease. RESULTS: With the exception of a subset of patients with limited-stage FL treated with radiation therapy, no curative treatment exists for the majority of patients with FL. The decision on when to start treatment is based on the presence of symptoms, bulky disease, or abnormalities in hematologic parameters that can be attributed to FL. Prognostic scoring systems such as the Follicular Lymphoma International Prognostic Index help in assessing prognosis but do not contribute to the decision on when to start treatment. There are numerous effective chemotherapeutic regimens for the treatment of advanced-stage FL, but none show a definitive improvement in overall survival. Maintenance and consolidation regimens have also been shown to be effective treatments of FL, with significant improvements in progression-free survival and possibly overall survival. CONCLUSIONS: Newer prognostic tests are in development that may help to guide the decision on which patients may benefit from early treatment. In addition, newer targeted agents that may improve on existing outcomes with less toxicity are currently being evaluated.

Ibrutinib is effective in the treatment of relapsed/refractory (R/R) marginal zone lymphoma (MZL) with an overall response rate (ORR) of 48%. However, factors associated with response (or lack thereof) to ibrutinib in R/R MZL in clinical practice are largely unknown. To answer this question, we performed a multicenter (25 US centers) cohort study and divided the study population into three groups: "ibrutinib responders"-patients who achieved complete or partial response (CR/PR) to ibrutinib; "stable disease (SD)"; and "primary progressors (PP)"-patients with progression of disease as their best response to ibrutinib. One hundred and nineteen patients met the eligibility criteria with 58%/17% ORR/CR, 29% with SD, and 13% with PP. The median PFS and OS were 29 and 71.4 months, respectively, with no difference in PFS or OS based on the ibrutinib line of therapy or type of therapy before ibrutinib. Patients with complex cytogenetics had an inferior PFS (HR = 3.08, 95% CI 1.23-7.67, p = 0.02), while those with both complex cytogenetics (HR = 3.00, 95% CI 1.03-8.68, p = 0.04) and PP (HR = 13.94, 95% CI 5.17-37.62, p < 0.001) had inferior OS. Only primary refractory disease to first-line therapy predicted a higher probability of PP to ibrutinib (RR = 3.77, 95% CI 1.15-12.33, p = 0.03). In this largest study to date evaluating outcomes of R/R MZL treated with ibrutinib, we show that patients with primary refractory disease and those with PP on ibrutinib are very high-risk subsets and need to be prioritized for experimental therapies.

INTRODUCTION: Classical Hodgkin lymphoma (cHL) is a curable malignancy, with a complete remission rate of approximately 90%. However, relapse remains a significant cause of mortality. Prognostic factors are useful in guiding therapy. This is a large, single-institution study defining the clinicopathologic features, prognostic factors, and treatment outcomes of patients with cHL. PATIENTS AND METHODS: We reviewed 727 patients with cHL treated at H. Lee Moffitt Cancer Center and Research Institute from 1990 to 2017. Data on demographics, laboratory studies, and disease statuses were collected from the institutional database and electronic medical records. Statistical analyses, overall survival (OS), progression-free survival (PFS), and multivariate analyses were performed. RESULTS: The median age was 35 years. Fifty-four percent of patients were men; 45.6% had advanced stage disease; 82% were treated with ABVD (doxorubicin hydrochloride [adriamycin], bleomycin sulfate, vincristine, and dacarbazine) as frontline therapy; and 70% achieved complete response. The median PFS after first-line treatment was 16.8 years. The median OS of patients with early stage and advanced stage cHL was 19 and 12.9 years, respectively. Poor prognostic factors for OS included older age, advanced stage disease, presence of B symptoms, and a higher International Prognostic Score. CONCLUSION: Despite high cure rates, cHL accounted for the cause of death in 47% of patients who died during follow-up. Prognostic factors, such as age, stage at diagnosis, International Prognostic Score, and B symptoms, are helpful to guide treatment. Outcomes observed in this study are comparable with those reported in previously published studies.
