Purpose The question of whether cancer patients with severe respiratory failure benefit from veno-venous extracorporeal membrane oxygenation (vv-ECMO) remains unanswered. We, therefore, analyzed clinical characteristics and outcomes of a large cohort of cancer patients treated with vv-ECMO with the aim to identify prognostic factors. Methods 297 cancer patients from 19 German and Austrian hospitals who underwent vv-ECMO between 2009 and 2019 were retrospectively analyzed. A multivariable cox proportional hazards analysis for overall survival was performed. In addition, a propensity score-matched analysis and a latent class analysis were conducted. Results Patients had a median age of 56 (IQR 44-65) years and 214 (72%) were males. 159 (54%) had a solid tumor and 138 (47%) a hematologic malignancy. The 60-day overall survival rate was 26.8% (95% CI 22.1-32.4%). Low platelet count (HR 0.997, 95% CI 0.996-0.999; p = 0.0001 per 1000 platelets/[micro]l), elevated lactate levels (HR 1.048, 95% CI 1.012-1.084; p = 0.0077), and disease status (progressive disease [HR 1.871, 95% CI 1.081-3.238; p = 0.0253], newly diagnosed [HR 1.571, 95% CI 1.044-2.364; p = 0.0304]) were independent adverse prognostic factors for overall survival. A propensity score-matched analysis with patients who did not receive ECMO treatment showed no significant survival advantage for treatment with ECMO. Conclusion The overall survival of cancer patients who require vv-ECMO is poor. This study shows that the value of vv-ECMO in cancer patients with respiratory failure is still unclear and further research is needed. The risk factors identified in the present analysis may help to better select patients who may benefit from vv-ECMO., Author(s): Matthias Kochanek [sup.1], Jan Kochanek [sup.1], Boris Böll [sup.1], Dennis A.

Objectives: To investigate characteristics and outcomes of critically ill cancer patients with marked hyperferritinemia. Methods: A single‐center retrospective analysis comprising cancer patients with a ferritin level >10.000 μg/L treated in the intensive care unit (ICU) between 2012 and 2022 was conducted. Results: A total of 117 patients were included in the analysis. The median age was 59 years (range: 15–86 years). Females accounted for 48% of cases. 90% of patients had a hematologic malignancy. The median maximum ferritin level was 27.349 μg/L (range: 10.300–426.073 μg/L). The diagnostic criteria of septic shock were fulfilled in 51% of cases; 31% of patients had hemophagocytic lymphohistiocytosis (HLH) according to the HLH‐2004 criteria. Mechanical ventilation, renal replacement therapy and the use of vasopressors were necessary in 59%, 35% and 70% of cases, respectively. The ICU, hospital, 90‐day and 1‐year survival rates were 33.3%, 23.1%, 23.7% and 11.7%. Patients with septic shock had a worse survival than those without septic shock (p =.001); the survival of patients who fulfilled the HLH‐2004 criteria did not differ from those who did not (p =.88). Conclusion: Critically ill cancer patients with marked hyperferritinemia have poor outcomes. The present data may help to make informed decisions for this patient group. [ABSTRACT FROM AUTHOR]

The overall prognosis of older patients with acute myeloid leukemia (AML) is dismal. Only a small subgroup experiences long‐term survival. The discrimination between patients who are candidates for potentially curative approaches and those who are not is crucial since ‐ in addition to differences in terms of AML‐directed treatment ‐ different policies concerning intensive care unit (ICU) admission and involvement of specialized palliative care (SPC) seem obvious. To shed more light on characteristics, outcomes and health care utilization of older individuals with AML, we conducted an analysis comprising 107 consecutive patients with newly diagnosed AML aged ≥70 years treated at an academic tertiary care center in Germany between 1 January 2015, and 31 December 2020. Median age was 75 years (range: 70–87 years); 45% of patients were female. The proportion of patients receiving intensive induction chemotherapy was 35%, 55% had low‐intensity treatment and 10% did not receive AML‐directed treatment or follow‐up ended before treatment initiation. At least one ICU admission was documented for 47% of patients; SPC was involved in 43% of cases. Median follow‐up was 199 days. The median overall survival (OS) was 2.5 months; the 1‐year OS rate was 16%. Among patients who died during observation, the median proportion of time spent in the hospital between AML diagnosis and death was 56%. The most common places of death were normal wards (31%) and the ICU (28%). Patients less frequently died in a palliative care unit (14%) or at home (12%). In summary, results of the present analysis confirm the unfavorable prognosis of older patients with AML despite intensive health care utilization. Future efforts in this patient group should aim at optimizing the balance between appropriate AML‐directed treatment on the one hand and health care utilization including ICU stays on the other hand.

This article examines the use of specialized palliative care (SPC) in patients with haematological malignancies (HMs) undergoing chimeric antigen receptor (CAR) T-cell therapy. The study analyzed 200 patients in Germany who received CAR T-cell therapy and compared outcomes between those with and without SPC involvement. The study found that 21.5% of patients had SPC during their treatment, with higher rates in multiple myeloma patients. The most common symptoms documented in patients with SPC were weakness, loss of appetite, and the need for assistance with daily activities. The authors recommend offering SPC to patients receiving CAR T-cell therapy due to the significant symptom burden and the likelihood of not achieving long-term survival. [Extracted from the article]

Background: There are limited and partially contradictory data on the effects of airway pressure release ventilation (APRV) in COVID-19-associated acute respiratory distress syndrome (CARDS). Therefore, we analyzed the clinical outcome, complications, and longitudinal course of ventilation parameters and laboratory values in patients with CARDS, who were mechanically ventilated using APRV. Methods: Respective data from 4 intensive care units (ICUs) were collected and compared to a matched cohort of patients receiving conventional low tidal volume ventilation (LTV). Propensity score matching was performed based on age, sex, blood gas analysis, and APACHE II score at admission, as well as the implementation of prone positioning. Findings: Forty patients with CARDS, who were mechanically ventilated using APRV, and 40 patients receiving LTV were matched. No significant differences were detected for tidal volumes per predicted body weight, peak pressure values, and blood gas analyses on admission, 6 h post admission as well as on day 3 and day 7. Regarding ICU survival, no significant difference was identified between APRV patients (40%) and LTV patients (42%). Median duration of mechanical ventilation and duration of ICU treatment were comparable in both groups. Similar complication rates with respect to ventilator-associated pneumonia, septic shock, thromboembolic events, barotrauma, as well as the necessity for hemodialysis were detected for both groups. Clinical characteristics that were associated with increased mortality in a Cox proportional hazards regression analysis included age (hazard ratio [HR] 1.08, 95% confidence interval [CI] 1.04-1.1; P <.001), severe acute respiratory distress syndrome (HR 2.62, 95% CI 1.02-6.7; P =.046) and the occurrence of septic shock (HR 17.18, 95% CI 2.06-143.2; P =.009), but not the ventilation mode. Interpretation: Intensive care unit survival, duration of mechanical ventilation, and ICU treatment as well as ventilation-associated complication rates were equivalent using APRV compared to conventional LTV in patients with CARDS.

Simple Summary: Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare lymphoma entity accounting for ≈5% of all Hodgkin lymphoma (HL) cases. Since pathological characteristics and clinical presentation of NLPHL differ from classical HL and often resemble indolent B-cell non-Hodgkin lymphoma (B-NHL), nodular lymphocyte-predominant B-cell lymphoma has been proposed as an alternative name. In recent years, NLPHL has increasingly been treated with B-NHL-directed approaches, although more data are available on HL-directed treatment strategies. Overall, the outcomes of NLPHL patients are excellent, and the excess mortality in comparison with the general population is low. Future research in NLPHL will thus aim to determine strategies to reduce treatment intensity whenever possible. The definition of the optimal use of HL-directed and B-NHL-directed approaches in this disease is also pending. Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare B cell-derived lymphoma entity accounting for ≈5% of all Hodgkin lymphoma (HL) cases. In recent decades, patients with newly diagnosed NLPHL have usually been treated very similarly to classical HL (cHL). The 10-year overall survival rates with HL-directed approaches are in excess of 90%. However, pathological and clinical characteristics of NLPHL resemble indolent B-cell non-Hodgkin lymphoma (B-NHL) in some aspects. Thus, nodular lymphocyte-predominant B-cell lymphoma has been proposed as an alternative name, and the use of B-NHL-directed treatment strategies has become more common in NLPHL despite limited data. Given the often indolent clinical course of NLPHL, even in the case of relapse, the majority of patients with disease recurrence do not require high-dose chemotherapy and autologous stem cell transplantation but are treated sufficiently with low-intensity approaches such as single-agent anti-CD20 antibody treatment. The establishment of novel prognostic scores for NLPHL patients may optimize risk group and treatment allocation in newly diagnosed and relapsed disease. [ABSTRACT FROM AUTHOR]

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.

Objectives: Patients with classical Hodgkin lymphoma (cHL) relapsing after second‐line therapy have a dismal prognosis and novel approaches are required for this patient group. Based on promising (pre‐)clinical data and the favourable toxicity profile, we performed a phase II clinical trial with the JAK inhibitor ruxolitinib in patients with relapsed or refractory cHL (r/r cHL). Methods: Patients ≥18 years with histologically confirmed r/r cHL who failed second‐line treatment were included. Ruxolitinib was given orally at a dose of 25 mg twice daily in continuous 28‐day cycles until progression or unacceptable toxicity. Primary endpoint was the PET/CT‐based overall response rate (ORR; complete response (CR) or partial response (PR)) after 2 cycles; secondary endpoints included progression‐free (PFS) and overall survival (OS) as well as feasibility. The Jericho Trial adopted a 2‐stage phase 2 design (Simon 1989). Results: Among the 12 included patients in stage 1, 2 had a PR, 3 had a stable disease (SD) and 6 had progressive disease (PD) after two treatment cycles (ORR: 2/12 evaluable patients, 16.7%). Median PFS was 3.6 months, the 1‐year OS estimate was 50.6% (median not reached). The toxicity profile was favourable with only one grade IV adverse event (7.1%) reported. Conclusion: Ruxolitinib exhibited a favourable side effect profile but modest activity in r/r cHL. Although the formal stopping criterion after stage 1 was not met, the trial did not continue to stage 2 due to the low response and PFS rates observed in stage 1. [ABSTRACT FROM AUTHOR]

Summary: Different studies have characterized the microenvironment and its prognostic impact in classic Hodgkin lymphoma whereas such analyses are pending for nodular lymphocyte‐predominant Hodgkin lymphoma (NLPHL). We thus investigated characteristics of tumour cells and microenvironment in NLPHL and evaluated possible correlations with the clinical presentation. Lymph node samples from 152 NLPHL patients who had first‐line treatment within the randomized German Hodgkin Study Group HD16–HD18 trials were available and analysed with regard to IgD status and nuclear size of the tumour cells as well as presence of PD1‐positive follicular T helper cells and CD163‐positive macrophages in the microenvironment. While large tumour cell nuclei and high numbers of PD1‐positive follicular T helper cells in the microenvironment were more common in patients presenting with early/intermediate stages than in patients with advanced‐stage disease (p < 0.0001, unpaired t‐test; p = 0.0022, Mann–Whitney test), no differences between risk groups were observed in terms of the IgD status of the tumour cells and the content of CD163‐positive macrophages in the microenvironment. PD1‐positive follicular T helper cells were present in both cases with typical and variant growth patterns and rosetting around the tumour cells was observed in 96% of patients, indicating an important role of PD1‐positive follicular T helper cells in NLPHL.

Background: Reactivation of viruses such as Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are common in critically ill patients and have been described in patients with severe COVID-19. However, it is unclear whether these reactivations are associated with increased mortality and whether targeted treatments are beneficial. Methods: In a retrospective single-center cohort study, patients with severe COVID-19 treated on our intensive care unit (ICU) were screened for EBV and CMV reactivation as detected by polymerase chain reaction. If present, patient characteristics, temporal connections to severe acute respiratory syndrome coronavirus 2 diagnosis and corticosteroid use, the use of targeted treatments as well as the course of disease and outcome were analyzed. As control group, non-COVID-19 patients with sepsis, treated within the same time period on our ICU, served as control group to compare incidences of viral reactivation. Results: In 19 (16%) of 117 patients with severe COVID-19 treated on our ICU EBV reactivations were identified, comparable 18 (14%) of 126 in the non-COVID-19 control group (P=.672). Similarly, in 11 (9%) of 117 patients CMV reactivations were identified, comparable to the 16 (13%) of 126 in the non-COVID-19 sepsis patients (P=.296). The majority of EBV (58%) and CMV reactivations (55%) were detected in patients under systemic corticosteroid treatment. 7 (37%) of 19 patients with EBV reactivation survived the ICU stay, 2 (29%) of 7 patients with rituximab treatment and 5 (42%) of 12 patients without treatment (P=.568). Five (50%) of 10 patients with CMV reactivation survived the ICU stay, 5 (83%) of 6 patients with ganciclovir treatment and 0 of 4 patients without treatment (P=.048). Follow-up analysis in these patients showed that the initiation of treatment lead to decrease in viral load. Conclusion: Critically ill patients with COVID-19 are at a high risk for EBV and CMV reactivations. Whether these reactivations are a cause of hyperinflammation and require targeted treatment remains uncertain. However, in patients with clinical deterioration or signs of hyperinflammation targeted treatment might be beneficial and warrants further studying. [ABSTRACT FROM AUTHOR]
