Background: Intensified systemic chemotherapy has the highest primary cure rate for advanced-stage, classical Hodgkin lymphoma but this comes with a cost of severe and potentially life long, persisting toxicities. With the new regimen of brentuximab vedotin, etoposide, cyclophosphamide, doxorubicin, dacarbazine, and dexamethasone (BrECADD), we aimed to improve the risk-to-benefit ratio of treatment of advanced-stage, classical Hodgkin lymphoma guided by PET after two cycles.

Methods: This randomised, multicentre, parallel, open-label, phase 3 trial was done in 233 trial sites across nine countries.

Background: Despite major treatment advances, multiple myeloma remains incurable. The outcome of patients who are refractory to immunomodulatory agents, proteasome inhibitors, and anti-CD38 monoclonal antibodies is poor, and improved treatment strategies for this difficult-to-treat patient population are an unmet medical need.

Methods: This retrospective, unicentric analysis included 38 patients with relapsed/refractory multiple myeloma or plasma cell leukemia who underwent allogeneic stem cell transplantation (allo-HSCT) between 2013 and 2022.

We investigated the feasibility of a web-based cognitive-behavioral therapy to reduce cancer-related fatigue (CRF) among survivors of Hodgkin lymphoma. In this before-and-after trial, patients were primarily recruited via the German Hodgkin Study Group (GHSG). We assessed feasibility (response and drop-out rate) and preliminary efficacy including CRF, quality of life (QoL), and depressive symptomatology.

Understanding the longitudinal dynamics of behavior, their stability and change over time, are of great interest in the social and behavioral sciences. Researchers investigate the degree to which an observed measure reflects stable components of the construct, situational fluctuations, method effects, or just random measurement error. An important question in such models is whether autoregressive effects occur between the residuals, as in the trait-state occasion model (TSO model), or between the state variables, as in the latent state-trait model with autoregression (LST-AR model).

Background: Individualization of treatment in Hodgkin's lymphoma is necessary to improve cure rates and reduce treatment side effects. Currently, it is hindered by a lack of genomic characterization and sensitive molecular response assessment. Sequencing of cell-free DNA is a powerful strategy to understand the cancer genome and can be used for extremely sensitive disease monitoring.

Purpose: Evidence on the effect of self-protection via social distancing and wearing face-masks on infections during chemotherapy is currently not available. We asked if the occurrence of acute infections during chemotherapy for advanced-stage Hodgkin lymphoma (HL) decreased when COVID-19 protection measures were in effect.

Methods: We analyzed the occurrence of infections during all documented eBEACOPP cycles starting between 01 March and 30 June of 2017 to 2020 in patients treated within the GHSG HD21 study in Germany and compared the infection rates and characteristics by logistic regression models and means of descriptive statistics.

We retrospectively investigated histopathological growth patterns in individuals with advanced nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) treated within the randomized HD18 study. In all, 35/60 patients (58%) presented with atypical growth patterns. Patients with atypical growth patterns more often had stage IV disease (P = 0·0354) and splenic involvement (P = 0·0048) than patients with typical growth patterns; a positive positron emission tomography after two cycles of chemotherapy (PET-2) tended to be more common (P = 0·1078).

Background: The German Hodgkin Study Group's HD18 trial established the safety and efficacy of PET-guided eBEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone in escalated doses) for the treatment of advanced-stage Hodgkin lymphoma. However, because of a protocol amendment during the enrolment period (June 1, 2011) that changed standard treatment from eight to six cycles, the results of the HD18 trial have been partially immature. We report a prespecified 5-year follow-up analysis of the completed HD18 trial.

Data on non-Hodgkin lymphoma (NHL) after classical Hodgkin lymphoma (cHL) are scarce. We therefore performed a retrospective analysis comprising 11·841 cHL patients who had first-line treatment within the randomized German Hodgkin Study Group (GHSG) HD7-HD15 studies. After a median follow-up of 106 months, 175 patients (1·5%) had developed NHL.

Facial nerve paralysis due to the infiltration by a lymphoma is rare and the prognosis remains poor. If perineural spread and meningeosis are suspected, quick interdisciplinary diagnostic work-up is recommended. It should include magnetic resonance imaging, biopsy of the lesion, bone marrow biopsy, and lumbar puncture.

Purpose: Many important details of health-related quality of life (HRQoL) after diagnosis and treatment of Hodgkin lymphoma (HL) are still unknown because large longitudinal studies of HRQoL are rare. Therefore, we analyzed a systematically assessed, comprehensive range of HRQoL domains in patients with HL of all stages from diagnosis up to 5 years of survivorship.

Patients And Methods: We included patients with HL age 18-60 years at diagnosis from the German Hodgkin Study Group trials HD13, HD14, and HD15.

Objective: Cancer-related fatigue (CRF) is among the most distressing symptoms reported by cancer survivors as compromising their quality of life. This study investigates the complex interplay between CRF and functional health (FH) in survivors of Hodgkin lymphoma by using longitudinal data to clarify the etiology of CRF.

Methods: Data from = 3596 survivors (HD13-15) from the German Hodgkin Study Group was analyzed using bivariate latent curve models with structured residuals to model how the interplay between CRF and FH unfolds over time across and within individuals.

Purpose: Vitamin D deficiency is described as a modifiable risk factor for the incidence of and mortality in many common cancers; however, data in Hodgkin lymphoma (HL) are lacking.

Patients And Methods: We thus performed a study measuring pretreatment vitamin D levels in prospectively treated patients with HL and correlated this with clinical outcomes. A total of 351 patients from the German Hodgkin Study Group clinical trials (HD7, HD8, and HD9) were included.

Background: Although intensified chemotherapy regimens have improved tumour control and survival in advanced-stage Hodgkin's lymphoma, data on the long-term sequelae are scarce. We did preplanned follow-up analyses of the German Hodgkin Study Group (GHSG) trials HD9 and HD12 to assess whether the primary results of these trials-which had shown that intensive initial therapy in advanced-stage Hodgkin's lymphoma has a beneficial effect on treatment outcomes-would continue with longer follow-up.

Methods: In HD9 (Feb 1, 1993, to March 10, 1998), 1282 patients with newly diagnosed, histology-proven, advanced-stage Hodgkin's lymphoma received eight alternating cycles of COPP and ABVD (COPP/ABVD), eight cycles of bBEACOPP, or eight cycles of eBEACOPP.

The international, randomized phase 3 HD15 trial established 6xeBEACOPP as standard therapy for patients with newly diagnosed advanced-stage Hodgkin lymphoma (HL) within the German Hodgkin Study Group (GHSG). We performed a follow-up analysis to assess long-term efficacy and safety of this approach. Between 2003 and 2008, 2182 patients aged 18 to 60 years were recruited and randomized in a 1:1:1 ratio between 8 or 6 cycles of eBEACOPP or 8 cycles of the dose-dense BEACOPP-14 regimen, each followed by 30 Gy radiotherapy in case of positron emission tomography (PET)-positive residual lesions ≥2.

Background: A high proportion of patients with relapsed classical Hodgkin's lymphoma achieve a response with the antibody-drug conjugate brentuximab vedotin, and the drug is well tolerated. We modified the escalated BEACOPP regimen (eBEACOPP; bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) and implemented brentuximab vedotin with the aim to reduce toxic effects while maintaining the protocol's efficacy.

Methods: We did an open-label, multicentre, randomised phase 2 study at 20 study sites in Germany.

Purpose Combined-modality treatment is widely considered the standard of care in early-stage Hodgkin lymphoma (HL), and treatment intensity has been reduced over the last years. Long-term follow-up is important to judge both efficacy and safety of the different therapies used. Patients and Methods We analyzed updated follow-up data on 4,276 patients treated within the German Hodgkin Study Group trials HD7 and HD10 for early-stage favorable HL and HD8 and HD11 for early-stage unfavorable HL between 1993 and 2003.

Background: Advanced stage Hodgkin's lymphoma represents a heterogeneous group of patients with different risk profiles. Data suggests that interim PET assessment during chemotherapy is superior to baseline international prognostic scoring in terms of predicting long-term treatment outcome in patients with Hodgkin's lymphoma. We therefore hypothesised that early interim PET-imaging after two courses of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) might be suitable for guiding treatment in patients with advanced stage Hodgkin's lymphoma.

Purpose Cancer-related fatigue occurs frequently in patients with Hodgkin lymphoma (HL) and has a major impact on their quality of life. We hypothesized that severe fatigue (sFA) might have an impact on patients' treatment outcome and social reintegration. Methods Of 5,306 patients enrolled in the German Hodgkin Study Group's fifth generation of clinical trials in HL (HD13, HD14, and HD15; nonqualified and older [> 60 years] patients excluded), 4,529 provided data on health-related quality of life.

Background: Patients with Hodgkin's lymphoma might have persistent fatigue even years after treatment. However, knowledge of the development of fatigue persisting long after completion of treatment is limited. Therefore, we did a detailed analysis of fatigue in our first-line clinical trials for early-stage favourable (HD13 trial), early-stage unfavourable (HD14 trial), and advanced-stage (HD15 trial) Hodgkin's lymphoma.
