RESUMO
Cutaneous paraneoplastic syndromes due to Hodgkin lymphoma present with a wide spectrum of clinical manifestations from generalized pruritus to exfoliative erythroderma. We summarize the clinical findings and outcomes of 14 patients with Hodgkin lymphoma and associated cutaneous paraneoplastic syndromes treated at Mayo Clinic over the past 3 decades. Cutaneous paraneoplastic syndromes may be present at the time of lymphoma diagnosis, whereas in other patients, it may appear at the time of relapse, including patients with initial absence of cutaneous manifestations during the initial lymphoma presentation. Our results indicate that complete resolution of the paraneoplastic syndrome is associated with significantly improved overall survival. Recognition of cutaneous paraneoplastic syndromes is a crucial surrogate of relapsed malignancy and treatment requires targeting the underlying malignancy.

Brentuximab vedotin (BV) and nivolumab are increasingly utilized as a novel regimen in patients with relapsed/refractory classical Hodgkin lymphoma (cHL). A 26-year-old male presented to the hospital with refractory diabetic ketoacidosis and multiple electrolyte abnormalities, 9 days after the first dose of brentuximab vedotin and nivolumab for recurrent classical Hodgkin lymphoma. During his hospitalization, he developed multi-organ failure. His workup showed elevated cytokine levels concerning severe cytokine release syndrome (CRS) and hemophagocytic lymphohistiocytosis (HLH)-like syndrome. Despite treatment with CRS- and HLH-directed therapies, his clinical status deteriorated due to ongoing multifactorial shock and worsening multi-organ dysfunction, and comfort care measures were eventually pursued. To our knowledge, there have been no other cases reported of HLH-like syndrome after the combination of BV and nivolumab in patients with cHL. This case of a fatal adverse event following one dose of BV and nivolumab underscores the vital need for close monitoring of patients receiving this treatment regimen.
RESUMO
Unirradiated relapsed/refractory (r/r) B-cell non-Hodgkin lymphoma (NHL) patients who undergo anti-CD19 Chimeric Antigen Receptor T-cell Therapy (CART) have a predominant localized pattern of relapse, the significance of which is heightened in individuals with limited/localized pre-CART disease. This study reports on the outcomes of r/r NHL patients with limited (<5 involved sites) disease bridged with or without radiotherapy (BRT). A multi-center retrospective review of 150 patients with r/r NHL who received CART with <5 disease sites prior to leukapheresis was performed. Bridging treatment, if any, was administered between leukapheresis and CART infusion. Study endpoints included relapse free-survival (RFS), event-free survival (EFS) and overall survival (OS). Prior to CART infusion, 48 (32%) patients received BRT and 102 (68%) did not. The median follow-up was 21 months. Following CART infusion, BRT patients had higher objective response (92% vs 78%, p=0.046) and sustained complete response (54% vs 33%, p=0.015) rates. Local relapse in sites present prior to CART was lower in the BRT group (21% vs. 46%, p=0.003). BRT patients had improved 2-year RFS (53% vs 44%, p=0.023) and 2-year EFS (37% vs 34%, p=0.039) compared to no BRT patients. The impact of BRT was most prominent in patients who had ≤2 pre-CART involved disease sites, with 2-year RFS of 62% in patients who received BRT compared to 42% in those who did not (p=0.002). BRT prior to CART for patients with limited (<5 involved disease sites) r/r NHL improves response rate, local control, RFS, and EFS without causing significant toxicities.
RESUMO
CD19 CAR T-cell (CAR-T) therapy is commonly administered to patients with relapsed or refractory large B-cell lymphomas (LBCL), but salvage or bridging therapy can sometimes lead to a complete response (CR) prior to infusion. Limited studies have assessed the outcomes of patients infused in CR. A total of 134 patients with LBCL in CR prior to CAR-T infusion were identified from the CIBMTR registry, with median prior lines of therapy of 3 (range 2-9). At two years post-infusion, the probability of progression-free survival was 43.5% (95% CI 34.4-52.8) and the probability of overall survival was 63.8% (95% CI 54.4-72.6). The cumulative incidence rates of non-relapse mortality and relapse/progression at two years were 9.2% (95% CI 4.5-15.4) and 47.3% (95% CI 38.2-56.6), respectively. The rate of grade 3 or higher cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were 2.2% and 8.2%, respectively. In summary, CAR-T in heavily pretreated patients with LBCL who are in CR following two or more lines of prior therapy demonstrate that a subset of patients may remain free of progression at two years. Additionally, the toxicity profile was impressive with very low rates of grade 3 CRS and ICANS.
