RESUMEN
Patients with advanced-stage Hodgkin lymphoma treated with ABVD who have a positive interim FDG-PET (iPET) have a poor prognosis. Escalation to BEACOPP has been shown to improve progression-free survival (PFS). However, randomized trials are lacking to determine the best strategy for intensification. We report on A-AVD escalation treatment outcomes for 15 iPET-positive patients post-ABVD. Overall response and complete response rates were 80% and 60%, respectively. Four patients underwent salvage therapy followed by autologous stem cell transplantation. At a median 17-month follow-up, all patients are alive, 87% in complete remission, and 1-year PFS was 57.8%. For patients ineligible for BEACOPP due to age, comorbidities, or preference, A-AVD escalation may be a viable alternative.

BACKGROUND AND PURPOSE: A real-time biomarker in chemotherapy-induced peripheral neurotoxicity (CIPN) would be useful for clinical decision-making during treatment. Neurofilament light chain (NfL) can be detected in blood in the case of neuroaxonal damage. The aim of the study was to compare the levels of plasma NfL (pNfL) according to the type of chemotherapeutic agent and the severity of CIPN. METHODS: This single-center prospective observational longitudinal study included patients treated with paclitaxel (TX; n = 34), brentuximab vedotin (BV; n = 29), or oxaliplatin (PT; n = 19). All patients were assessed using the Total Neuropathy Score-clinical version and Common Terminology Criteria for Adverse Events before, during, and up to 6-12 months after the end of treatment. Nerve conduction studies (NCS) were performed before and after chemotherapy discontinuation. Consecutive plasma samples were analyzed for NfL levels using a Simoa® analyzer. Changes in pNfL were compared between groups and were eventually correlated with clinical and NCS data. Clinically relevant (CR) CIPN was considered to be grade ≥ 2. RESULTS: Eighty-two patients, mostly women (59.8%), were included. One third of the patients who received TX (29.4%), BV (31%), or PT (36.8%) developed CR-CIPN, respectively, without differences among them (p = 0.854). Although pNfL significantly increased during treatment and decreased throughout the recovery period in all three groups, patients receiving TX showed significantly greater and earlier changes in pNfL levels compared to the other agents (p < 0.001). CONCLUSIONS: A variable change in pNfL is observed depending on the type of agent and mechanism of neurotoxicity with comparable CIPN severity, strongly implying the need to identify different cutoff values for each agent.

BACKGROUND AND PURPOSE: Peripheral neuropathy is a frequent complication of brentuximab vedotin (BV), used in CD30+ lymphoma treatment. Classic BV-induced neuropathy (BV-CN) is a mild distal sensory axonal polyneuropathy. Severe BV-induced inflammatory neuropathies (BV-IN) have been described. BV-IN contribute to lymphoma-associated morbidity but might be immunotherapy-responsive. Our primary objective was to evaluate the rate of BV-IN. Our secondary objectives were to determine risk factors and warning signs. METHODS: We conducted a retrospective cohort study on all patients treated with BV at our center between April 2014 and September 2021. Clinical, biological, and electrophysiological data were collected. BV-induced neuropathy was defined as the occurrence of neuropathy up to 3 months after BV discontinuation. BV-IN was defined with criteria adapted from European Academy of Neurology/Peripheral Nerve Society 2021 electrodiagnostic criteria for chronic inflammatory demyelinating polyradiculoneuropathy. Other neuropathies were classified as BV-CN. RESULTS: Among 83 patients, 41 (49%) developed neuropathy: 35 BV-CN and 6 BV-IN. Thus, the rate of BV-IN was 7.2%. Compared to patients with BV-CN, no predisposing factor was identified. However, patients with BV-IN more frequently presented muscle weakness (67% vs. 5.7%, p < 0.05), gait disorders (83% vs. 20%, p < 0.05), or acute or subacute onset (67% vs. 14%, p < 0.05). BV-IN was frequently more severe (Common Terminology Criteria for Adverse Events grade ≥3; 50% vs. 0%, p < 0.05). Four patients were treated with immunotherapy. CONCLUSIONS: Brentuximab vedotin-induced neuropathy is an overlooked complication. Based on four easily identifiable "red flags", we provide an algorithm to help non-neurologist physicians that care for BV-treated patients to detect BV-IN. The aim of the algorithm is to decrease the diagnostic and management delay of this disabling neuropathy.

Aim: To understand US physicians' frontline (1L) treatment preferences/decision-making for stage III/IV classic Hodgkin lymphoma (cHL). Materials & methods: Medical oncologists and/or hematologists (≥2 years' practice experience) who treat adults with stage III/IV cHL were surveyed online (October-November 2020). Results: Participants (n = 301) most commonly considered trial efficacy/safety data and national guidelines when selecting 1L cHL treatments. Most physicians (91%) rated overall survival (OS) as the most essential attribute when selecting 1L treatment. Variability was seen among regimen selection for hypothetical newly diagnosed patients, with OS cited as the most common reason for regimen selection. Conclusion: While treatment selection varied based on patient characteristics, US physicians consistently cited OS as the top factor considered when selecting a 1L treatment for cHL.
Classic Hodgkin lymphoma (cHL) is a type of cancer that grows in lymph nodes. The researchers created a survey to assess how doctors in the USA choose medicine to treat patients who are newly diagnosed with an advanced stage of cHL (stage 3 or 4 out of 4 stages). We surveyed 301 doctors who treat patients with cHL. When choosing a medicine to treat cHL, most doctors said they consider results from research studies, how well the medicine works, information on the medicine's safety and recommendations in official guidelines. Most doctors said that overall survival (how long the patient survives after being diagnosed with cHL) is the most important outcome they consider when choosing a medicine to treat cHL. During the survey, doctors saw four unique patient profiles. These profiles differed in age, disease stage (how far along the cHL is) and other illnesses the patient has. While medicine choice was different across profiles, overall survival was still the reason for choosing each individual patient's medicine. These survey results show that doctors in the USA highly consider overall survival when choosing medicine for patients newly diagnosed with an advanced stage of cHL.

BACKGROUND: The subcellular distribution of CD30 on mast cells and the presence of eosinophils in cutaneous mastocytosis require further investigation, especially as the cell surface expression of CD30 is critical for the therapeutic response of systemic mastocytosis to brentuximab vedotin. OBJECTIVE: Investigation of 147 biopsy specimens from 143 patients with cutaneous mastocytosis for mast cell density and distribution, frequency of CD30 expression, CD30 staining patterns, and presence and distribution of eosinophils. Correlation with clinical patterns. METHODS: Retrospective multicenter immunohistochemical study of CD30 expression, eosinophils and basic clinical data in cutaneous mastocytosis. RESULTS: CD30 expression was found in all samples (cut-off: ≥1%), whereby the staining was predominantly cytoplasmic in 99% of the samples. Additional membrane staining was detected in 62% of the samples. Surface expression of CD30 was more common in biopsy specimens with a high mast cell burden and in biopsy specimens with a higher CD30 expression rate. Eosinophils were admixed in 58% of the samples. Females and older patients showed a trend of a lower mast cell burden. LIMITATIONS: Retrospective study on formalin-fixed and paraffin-embedded tissue without functional analysis. CONCLUSION: Most cases of cutaneous mastocytosis show cell surface expression of CD30 expression and is, therefore, in principle, accessible for therapy with antibodies against CD30, provided the overall situation of the patient warrants.
RESUMEN
Hodgkin lymphoma is characterized by a high cure rate in the modern era of medicine regardless of stage, but patients suffer from a high risk of comorbidity associated with the administered therapy. The main aim of this review article is to assess and analyze the various comorbidities associated with Hodgkin lymphoma and address the survivorship of patients, including fertility, secondary cancers due to cardiovascular toxicity, and quality of life. Furthermore, this review explores the optimal strategy for detecting relapse. The treatment paradigm of Hodgkin lymphoma has shifted, with a paradigm shift toward achieving a high cure rate and low toxicity as a standard of care in this patient population. Checkpoint inhibitors, especially nivolumab, in combination with chemotherapy are increasingly being studied in the first line of therapy. However, their long-term toxicity remains to be assessed in longer follow-up. In conclusion, Hodgkin lymphoma survivors, regardless of their treatment, should be followed up individually by a multidisciplinary survivorship team in order to detect and properly treat the long-term side effects of therapy.

CD30 is a transmembrane protein from the tumour necrosis factor receptor superfamily. It is expressed on a small subset of activated T and B lymphocytes, and various lymphoid neoplasms. CD30 is a particularly interesting treatment target because its levels are high in tumours but low in healthy tissues. Several therapeutic strategies targeting CD30 have been developed, including monoclonal antibodies, conjugated antibodies (combination of brentuximab vedotin with chemotherapy or immunotherapy), bispecific antibodies and cell and gene therapies, such as anti-CD30 CAR-T cells in particular. We briefly review the biology of CD30 which makes it a good therapeutic target, and we describe all of the anti-CD30 therapies that have emerged to date.

Autologous hematopoietic stem cell transplant (ASCT) is the standard curative treatment for patients with high-risk relapsed/refractory Hodgkin lymphoma (R/R HL). The AETHERA study showed survival gain with Brentuximab Vedotin (BV) maintenance after ASCT in BV-naive patients, which was recently confirmed in the retrospective AMAHRELIS cohort, including a majority of BV-exposed patients. However, this approach has not been compared to intensive tandem auto/auto or auto/allo transplant strategies, which were used before BV approval. Here, we matched BV maintenance (AMAHRELIS) and tandem SCT (HR2009) cohorts, and observed that BV maintenance was associated with better survival outcome in patients with HR R/R HL.

BACKGROUND: Since Food and Drug Administration approval of brentuximab vedotin in combination with cyclophosphamide, doxorubicin, and prednisone (Aâ +â CHP) as initial therapy for previously untreated CD30-expressing peripheral T-cell lymphoma (PTCL), there has been limited research on real-world patient characteristics, treatment patterns, and clinical outcomes. METHODS: We retrospectively analyzed claims of patients with PTCL treated with frontline Aâ +â CHP or CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) using the Symphony Health Solutions database. Adults with International Classification of Diseases-9/10 PTCL diagnosis codes who initiated Aâ +â CHP or CHOP between November 2018 and July 2021 were included. A 1:1 propensity score matching analysis was performed that adjusted for potential confounders between groups. RESULTS: A total of 1344 patients were included (Aâ +â CHP, nâ =â 749; CHOP, nâ =â 595). Before matching, 61% were men; median age at index was 62 (Aâ +â CHP) and 69 (CHOP) years. The most common Aâ +â CHP-treated PTCL subtypes were systemic anaplastic large cell lymphoma (sALCL; 51%), PTCL-not otherwise specified (NOS; 30%), and angioimmunoblastic T-cell lymphoma (AITL; 12%); the most common CHOP-treated subtypes were PTCL-NOS (51%) and AITL (19%). After matching, similar proportions of patients treated with Aâ +â CHP and CHOP received granulocyte colony-stimulating factor (89% vs. 86%, Pâ =â .3). Fewer patients treated with Aâ +â CHP received subsequent therapy than CHOP overall (20% vs. 30%, Pâ <â .001) and specifically with the sALCL subtype (15% vs. 28%, Pâ =â .025). CONCLUSIONS: Characteristics and management of this real-world PTCL population who were older and had a higher comorbidity burden than that in the ECHELON-2 trial demonstrate the importance of retrospective studies when assessing the impact of new regimens on clinical practice.

The treatment of peripheral T-cell lymphomas is challenging, as they often display a severe prognosis and lack effective treatment strategies. We will try to answer three burning questions: can we differentiate the initial treatment based on the histotype and the clinical presentation of peripheral T-cell lymphoma patients? Do we require an autologous stem cell transplantation in all patients? Is there room for improvement in the setting of relapsed and refractory disease?

Autologous stem cell transplantation (ASCT) is the standard treatment of primary refractory or relapsed Hodgkin-lymphoma, which can provide a cure rate of about 50%. The aim of our study was to analyze the data of 126 HL patients undergoing AHSCT in Hungary between 01/01/2016 and 31/12/2020. We assessed the progression-free and overall survival, the prognostic role of PET/CT performed before transplantation and effect of brentuximab vedotin (BV) treatment on survival outcomes. The median follow-up time from AHSCT was 39 (1-76) months. The 5-year OS comparing PET- and PET + patients was 90% v. 74% (p = 0.039), and 5-year PFS was 74% v. 40% (p = 0.001). There was no difference in either OS or PFS compared to those who did not receive BV before AHSCT. We compared BV treatments based on their indication (BV only after AHSCT as maintenance therapy, BV before and after AHSCT as maintenance treatment, BV only before AHSCT, no BV treatment). There was statistically significant difference in the 5-year PFS based on the inication of BV therapy. Recovery rates of our R/R HL patient population, who underwent AHSCT, improved significantly. Our positive results can be attributed to the PET/CT directed, response-adapted treatment approach, and the widespread use of BV.

The AETHERA trial demonstrated that brentuximab vedotin (BV) consolidation after autologous stem cell transplantation (ASCT) in patients with Hodgkin lymphoma (HL) at high risk of relapse/progression increases progression-free survival (PFS). Patients previously exposed to BV were excluded from that trial. However, BV alone or in combination with chemotherapy is frequently used as front-line treatment and/or pre-ASCT salvage therapy. We analyzed data from 156 patients with high-risk HL who underwent ASCT with (BV-CON, n = 62) or without (non-BV, n = 94) BV consolidation. Fifty-seven patients received BV-based salvage regimens before ASCT. The 3-year overall survival and PFS for all patients were 91.6% and 70.0%, respectively. Multivariate analysis showed that BV-CON was associated with better PFS (HR 0.39, p = 0.01), whereas positive PET at transplant leaded to worse PFS (HR 2.71, p = 0.001). BV-CON improved PFS in PET-positive patients (72.2% vs. 43.0%, p = 0.05), with a beneficial trend observed in PET negative (88.8% vs. 75.2%, p = 0.09). BV-CON patients with or without BV exposure pre-ASCT had a significantly better PFS than non-BV with or without BV pretransplant treatment (HR 0.36, p = 0.004). The efficacy of real-life BV consolidation therapy was similar to that in the AETHERA trial. This therapeutic strategy improves survival independently of BV exposure prior to ASCT.

Post-transplant lymphoproliferative disorder (PTLD) is a common secondary malignancy after transplantation, which has been recognized as a life-threatening complication. Hodgkin lymphoma (HL)-type PTLD is the rarest of four subtypes of PTLD, which has no treatment guideline due to its rarity. HL-type PTLD includes classical HL-type PTLD (cHL-PTLD) and HL-like PTLD. In our study, we reported the case of successful treatment using brentuximab vedotin (BV) plus sirolimus for a patient with classical HL-type PTLD in detail. Lymph node biopsy showed a picture of classical HL with mixed cellularity subtype, and immunophenotyping suggested CD30 strong positivity. Due to his impaired physical condition, we decided against intensive chemotherapy and started BV treatment with immunosuppressive agents switched to sirolimus. The 66-year-old patient with cHL-PTLD had achieved a durable complete remission for over a 1-year follow-up period. Additionally, we analyzed the clinical profile and outcomes in PTLD patients who used BV monotherapy or combined therapy by literature review. In summary, this case-based review might provide clues that treatment of cHL-PTLD with new modalities such as BV monotherapy or combination therapy, together with improvements in the immunosuppressive regimens like sirolimus, might be a feasible and chemotherapy-free approach, but warrants further evaluation in a larger patient cohort.
RESUMEN
CD30 is overexpressed in several lymphoma types, including classic Hodgkin lymphoma (cHL), some peripheral T-cell lymphomas (PTCL), and some cutaneous T-cell lymphomas. The antibody-drug conjugate brentuximab vedotin targets CD30-positive cells and has been evaluated for the treatment of various lymphoma entities. This narrative review summarizes 10 years of experience with brentuximab vedotin for the treatment of CD30-positive lymphomas, discusses novel therapies targeting CD30 in development, and highlights remaining controversies relating to CD30-targeted therapy across lymphoma types. The collective body of evidence for brentuximab vedotin demonstrates that exploitation of CD30 can provide sustained benefits across a range of different CD30-positive lymphomas, in both clinical trials and real-world settings. Preliminary experience with brentuximab vedotin in combination with immune checkpoint inhibitors for relapsed/refractory cHL is encouraging, but further exploration is required. The optimal use of brentuximab vedotin for first-line therapy of PTCL remains to be determined. Further research is required on brentuximab vedotin treatment in high-risk patient populations, and in rare lymphoma subtypes, for which no standard of care exists. Novel therapies targeting CD30 include chimeric antigen receptor therapies and bispecific antibody T-cell engagers, which may be expected to further improve outcomes for patients with CD30-positive lymphomas in the coming years.

PURPOSEOF REVIEW: The main aim of this review is to summarize first-line therapy of nodal T-cell non-Hodgkin lymphoma. RECENT FINDINGS: Current treatment with CHOP chemotherapy results in poor outcomes in the majority of patients. However, there are advances within the field. First breakthrough is the ECHELON-2 trial which showed that the addition of brentuximab vedotin improves outcomes in anaplastic large cell lymphoma. However, other types of peripheral T-cell non-Hodgkin lymphoma were underrepresented with optimal treatment not known. Second breakthrough is an increase of autologous stem cell transplantation usage in the first complete metabolic remission, except in ALK + anaplastic large cell lymphoma, offering better disease control. Despite advances in the field, CHOP remains the standard treatment for the majority of these lymphomas, but multiple trials are underway with the aim to improve this unmet need in hematology and, hopefully, leading us to a new era in the treatment of peripheral T-cell lymphomas.

PURPOSE: This study aimed to systematically review and critically appraise cost-effectiveness studies on Brentuximab vedotin (BV) in patients with Hodgkin lymphoma (HL). METHODS: The PubMed, Scopus, Web of Science core collection, and Embase databases were searched until July 3, 2022. We included published full economic evaluation studies on BV for treating patients with HL. The methodological quality of the studies was assessed using the Quality of Health Economic Studies (QHES) checklist. Meanwhile, we used qualitative synthesis to analyze the findings. We converted the incremental cost-effectiveness ratios (ICERs) to the value of the US dollar in 2022. RESULTS: Eight economic evaluations met the study's inclusion criteria. The results of three studies that compared BV plus doxorubicin, vinblastine, and dacarbazine (BV + AVD) front-line therapy with doxorubicin, bleomycin, vincristine, and dacarbazine (ABVD) showed that BV is unlikely to be cost-effective as a front-line treatment in patients advanced stage (III or IV) HL. Four studies investigated the cost-effectiveness of BV in patients with relapsed or refractory (R/R) HL after autologous stem cell transplantation (ASCT). BV was not cost-effective in the reviewed studies at accepted thresholds. In addition, the adjusted ICERs ranged from $65,382 to $374,896 per quality-adjusted life-year (QALY). The key drivers of cost-effectiveness were medication costs, hazard ratio for BV, and utilities. CONCLUSION: Available economic evaluations show that using BV as front-line treatment or consolidation therapy is not cost-effective based on specific ICER thresholds for patients with HL or R/R HL. To decide on this orphan drug, we should consider other factors such as existence of alternative treatment options, clinical benefits, and disease burden.

The long-term survival of Hodgkin lymphoma (HL) patients treated according to the current standard of care is excellent. Combined-modality schedules (ABVD plus radiotherapy) in early-stage disease, along with treatment intensity adaptation to early metabolic response assessed by PET/CT in advanced stage HL, have been the cornerstones of risk stratification and treatment decision-making, minimizing treatment-related complications while keeping efficacy. Nevertheless, a non-negligible number of patients are primary refractory or relapse after front-line treatment. Novel immunotherapeutic agents, namely Brentuximab Vedotin (BV) and immune checkpoint inhibitors (CPI), have already shown outstanding efficacy in a relapsed/refractory setting in recent landmark studies. Several phase 2 single-arm studies suggest that the addition of these agents in the frontline setting could further improve long-term disease control permitting one to reduce the exposure to cytotoxic drugs. However, a longer follow-up is needed. At the time of this writing, the only randomized phase 3 trial so far published is the ECHELON-1, which compares 1 to 1 BV-AVD (Bleomycin is replaced by BV) with standard ABVD in untreated advanced-stage III and IV HL. The ECHELON-1 trial has proven that BV-AVD is safe and more effective both in terms of long-term disease control and overall survival. Just recently, the results of the S1826 SWOG trial demonstrated that the combination nivolumab-AVD (N-AVD) is better than BV-AVD, while preliminary results of other randomized ongoing phase 3 trials incorporating anti-PD-1 in this setting will be soon available. The aim of this review is to present the recent data regarding these novel agents in first-line treatment of HL and to highlight current and future trends which will hopefully reshape the overall management of this disease.

Classic Hodgkin lymphoma (cHL) is one of the common subtypes of malignant lymphoma in Western countries. Although patients with HL showed unsatisfactory results in the 1960s, the clinical development in radiotherapy and chemotherapy based on several clinical trials over the last 50 years has made cHL a curable disease with a favorable outcome. As a result, late-onset treatment-related toxicities such as second primary malignancies and cardiac events are thought to be a significant issue especially in early-stage patients. To minimize the toxic effects while maximizing the antitumor efficacy, several clinical trials to evaluate response-adapted strategies using interim PET scans and novel agents, such as brentuximab vedotin (BV) and/or immune checkpoint inhibitor (ICI) are currently underway. In this review, the author summarizes currently available data on PET-adapted and BV and/or ICI-containing therapies for untreated cHL, and discusses their future prospects in cHL treatment.

Primary pulmonary Hodgkin's lymphoma (PPHL) is a rare subtype of lymphoma that comprises a small percentage of primary pulmonary lymphomas. Due to its rarity and nonspecific symptoms, PPHL often presents diagnostic challenges. This case report presents a unique case of PPHL mimicking granulomatosis with polyangiitis, emphasizing the difficulties encountered during the diagnostic process. A 53-year-old female presented with vague symptoms including weakness, oedema, dry cough, and nasal cavity ulceration. Laboratory investigations revealed elevated C-reactive protein levels, a white blood cell count with neutrophilia, and lymphopaenia. Initial treatment with oral corticosteroids for suspected polyangiitis yielded no response. The patient subsequently developed a low-grade fever and pruritic erythematous rash. Diagnostic procedures, including bronchial brush biopsy, bronchial washing, mediastinal lymph node biopsy, nasal cavity ulceration biopsy, and initial lung biopsy, were inconclusive and resulted in exclusion of granulomatosis with polyangiitis. A subsequent computed tomography scan indicated disease progression in the left lung. A lung biopsy revealed fibrotic tissue with nodules containing Hodgkin- Reed-Sternberg cells, leading to the final diagnosis of classic Hodgkin lymphoma, nodular sclerosis subtype. Positron emission tomography scan findings confirmed PPHL. The patient received multiple chemotherapeutic regimens, with brentuximab vedotin demonstrating efficacy as the sole effective treatment. This exceptional case of PPHL underscores the extensive diagnostic and therapeutic workup involving a multidisciplinary team of clinicians, radiologists, and pathologists. Increased awareness of PPHL and its distinctive features will aid in the diagnosis of similar cases in the future, benefitting both clinicians and pathologists.
RESUMEN
BACKGROUND: The safety and efficacy of brentuximab vedotin (BV), an antibody-drug conjugate directed to the CD30 antigen, has been assessed in several trials in patients with peripheral T-cell lymphoma (PTCL), cutaneous T-cell lymphoma (CTCL), or B-cell non-Hodgkin lymphoma (NHL). The objective of this research was to examine the relationship between CD30 expression level and clinical response to BV. PATIENTS AND METHODS: We analyzed response in patients treated with BV monotherapy in 5 prospective clinical studies in relapsed or refractory PTCL, CTCL, or B-cell NHL. CD30 expression was assessed by immunohistochemistry (IHC) using the Ber H2 antibody for 275 patients. RESULTS: Across all 5 studies, 140 (50.9%) patients had tumors with CD30 expression <10%, including 60 (21.8%) with undetectable CD30 by IHC. No significant differences were observed for any study in overall response rates between patients with CD30 expression ≥10% or <10%. Median duration of response was also similar in the CD30 ≥10% and <10% groups for all studies. CONCLUSIONS: In this analysis of studies across a range of CD30-expressing lymphomas, CD30 expression alone, as measured by standard IHC, does not predict clinical benefit from BV, making the determination of a threshold level of expression uncertain.
