Reinduction therapy with everolimus in combination with dexamethasone, high-dose cytarabin and cisplatinum in patients with relapsed or refractory classical Hodgkin lymphoma: an experimental phase I/II multicentre trial of the German Hodgkin Study Group (GHSG HD-R3i).

Reinduction chemotherapy followed by high-dose chemotherapy and autologous stem cell transplant (HDCT + ASCT) is second-line standard of care for transplant-eligible patients with relapsed/refractory classical Hodgkin lymphoma (r/r cHL) but has a high failure rate. Because response to reinduction is predictive of the outcome after HDCT + ASCT, we aimed to improve the standard dexamethasone, high-dose cytarabine and cisplatinum (DHAP) reinduction regimen by addition of the oral mammalian target of rapamycin inhibitor everolimus (everDHAP). Transplant-eligible patients aged 18-60 years with histologically confirmed r/r cHL were included in this experimental phase I/II trial.

Pooled RT-qPCR testing for SARS-CoV-2 surveillance in schools - a cluster randomised trial.

Background: The extent to which children and adolescents contribute to SARS-CoV-2 transmission remains not fully understood. Novel high-capacity testing methods may provide real-time epidemiological data in educational settings helping to establish a rational approach to prevent and minimize SARS-CoV-2 transmission. We investigated whether pooling of samples for SARS-CoV-2 detection by RT-qPCR is a sensitive and feasible high-capacity diagnostic strategy for surveillance of SARS-CoV-2 infections in schools.

Whole-slide image analysis of the tumor microenvironment identifies low B-cell content as a predictor of adverse outcome in patients with advanced-stage classical Hodgkin lymphoma treated with BEACOPP.

A subset of patients with advanced-stage classical Hodgkin Lymphoma (cHL) relapse or progress following standard treatment. Given their dismal prognosis, identifying this group of patients upfront represents an important medical need. While prior research has identified characteristics of the tumor microenvironment, which are associated with cHL outcomes, biomarkers that are developed and validated in this high-risk group are still missing.

[Glaucoma Drainage Devices - Evaluation of Surgical Modifications to Avoid Postoperative Complications].

Background: In glaucoma therapy, there are many treatment options, such as glaucoma drainage devices (GDI). The aim of this study is to compare postoperative outcomes after using different surgical techniques.

Material And Methods: 269 eyes of 250 patients who received a GDI at the ophthalmological center at the university hospital in Cologne between February 2010 and September 2016 were included in this study.

Symptomatic osteonecrosis as a treatment complication in Hodgkin lymphoma: an analysis of the German Hodgkin Study Group (GHSG).

The majority of patients with Hodgkin Lymphoma (HL) can be cured with stage and risk adapted treatment today. Therefore, current research focuses on reducing long-term sequelae of treatment. Osteonecrosis (ON) is a severe long-term complication of HL treatment which has so far not been systematically evaluated.

Anatomical investigations on intraosseous access in stillborns - Comparison of different devices and techniques.

Aim: Intraosseous (IO)-access plays an alternative route during resuscitation. Our study was performed to investigate the successful rate of IO-access in preterm and term stillborns using different devices and techniques.

Methods: The cadavers used were legal donations.

Progression-free survival of early interim PET-positive patients with advanced stage Hodgkin's lymphoma treated with BEACOPP alone or in combination with rituximab (HD18): an open-label, international, randomised phase 3 study by the German Hodgkin Study Group.

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.

Impact of centralized diagnostic review on quality of initial staging in Hodgkin lymphoma: experience of the German Hodgkin Study Group.

Accurate clinical staging is crucial for adequate risk-adapted treatment in Hodgkin lymphoma (HL) to prevent patients from under- or over-treatment. Within the latest German Hodgkin Study Group trial generation, diagnostic findings such as histopathology, computerized tomography imaging and clinical risk factors were re-evaluated by expert panels. Here, we retrospectively analysed 5965 patients and identified 399 in who major discordant findings changed their first-line treatment allocation.

Impact of Bleomycin and Vincristine Dose Reductions in Patients With Advanced Hodgkin Lymphoma Treated With BEACOPP: An Analysis of the German Hodgkin Study Group HD12 and HD15 Trials.

Purpose: The role of bleomycin and vincristine in the treatment of patients with advanced Hodgkin lymphoma (HL) is unclear, and the impact of dose reductions of these drugs on outcome and tolerability has not been systematically assessed. Because both drugs can cause significant toxicity and are frequently discontinued, we performed an analysis of patients with HL treated with BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) in the German Hodgkin Study Group HD12 and HD15 trials.

Patients And Methods: Characteristics and outcome of patients were analyzed with respect to discontinuation of bleomycin and/or vincristine.

Relapse analysis of irradiated patients within the HD15 trial of the German Hodgkin Study Group.

Purpose: To determine, in the setting of advanced-stage of Hodgkin lymphoma (HL), whether relapses occur in the irradiated planning target volume and whether the definition of local radiation therapy (RT) used by the German Hodgkin Study Group (GHSG) is adequate, because there is no harmonization of field and volume definitions among the large cooperative groups in the treatment of advanced-stage HL.

Methods And Materials: All patients with residual disease of ≥ 2.5 cm after multiagent chemotherapy (CTX) were evaluated using additional positron emission tomography (PET), and those with a PET-positive result were irradiated with 30 Gy to the site of residual disease.

Assessment of tumor size reduction improves outcome prediction of positron emission tomography/computed tomography after chemotherapy in advanced-stage Hodgkin lymphoma.

Purpose: Positron emission tomography (PET) after chemotherapy can guide consolidating radiotherapy in advanced-stage Hodgkin lymphoma (HL). This analysis aims to improve outcome prediction by integrating additional criteria derived by computed tomography (CT).

Patients And Methods: The analysis set consisted of 739 patients with residues≥2.

Therapy-related acute myeloid leukemia and myelodysplastic syndromes in patients with Hodgkin lymphoma: a report from the German Hodgkin Study Group.

Therapy-related acute myeloid leukemia and myelodysplastic syndromes (t-AML/MDS) represent severe late effects in patients treated for Hodgkin lymphoma (HL). Because more recent data are scarce, we retrospectively analyzed incidence, outcome, and risk factors for the development of t-AML/MDS after HL. A total of 11,952 patients treated for newly diagnosed HL within German Hodgkin Study Group trials between 1993 and 2009 were considered.

Effect of initial treatment strategy on survival of patients with advanced-stage Hodgkin's lymphoma: a systematic review and network meta-analysis.

Background: Several treatment strategies are available for adults with advanced-stage Hodgkin's lymphoma, but studies assessing two alternative standards of care-increased dose bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPescalated), and doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD)-were not powered to test differences in overall survival. To guide treatment decisions in this population of patients, we did a systematic review and network meta-analysis to identify the best initial treatment strategy.

Methods: We searched the Cochrane Library, Medline, and conference proceedings for randomised controlled trials published between January, 1980, and June, 2013, that assessed overall survival in patients with advanced-stage Hodgkin's lymphoma given BEACOPPbaseline, BEACOPPescalated, BEACOPP variants, ABVD, cyclophosphamide (mechlorethamine), vincristine, procarbazine, and prednisone (C[M]OPP), hybrid or alternating chemotherapy regimens with ABVD as the backbone (eg, COPP/ABVD, MOPP/ABVD), or doxorubicin, vinblastine, mechlorethamine, vincristine, bleomycin, etoposide, and prednisone combined with radiation therapy (the Stanford V regimen).

Reduced-intensity chemotherapy and PET-guided radiotherapy in patients with advanced stage Hodgkin's lymphoma (HD15 trial): a randomised, open-label, phase 3 non-inferiority trial.

Background: The intensity of chemotherapy and need for additional radiotherapy in patients with advanced stage Hodgkin's lymphoma has been unclear. We did a prospective randomised clinical trial comparing two reduced-intensity chemotherapy variants with our previous standard regimen. Chemotherapy was followed by PET-guided radiotherapy.

Eight cycles of escalated-dose BEACOPP compared with four cycles of escalated-dose BEACOPP followed by four cycles of baseline-dose BEACOPP with or without radiotherapy in patients with advanced-stage hodgkin's lymphoma: final analysis of the HD12 trial of the German Hodgkin Study Group.

Purpose: Eight cycles of BEACOPP(escalated) (escalated dose of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) followed by radiotherapy (RT) to initial bulk or residual tumor mass is the German Hodgkin Study Group standard of care for advanced-stage Hodgkin's lymphoma (HL). However, treatment-related toxicity is a concern, and the role of RT in this setting is unclear. The HD12 study thus aimed to reduce toxicity while maintaining efficacy.

Lymphocyte-depleted classical Hodgkin's lymphoma: a comprehensive analysis from the German Hodgkin study group.

Purpose: To investigate the clinical characteristics and treatment outcome of patients with lymphocyte-depleted classical Hodgkin's lymphoma (LDCHL) compared with other histologic subtypes of Hodgkin's lymphoma (HL).

Patients And Methods: From a total of 12,155 evaluable patients with biopsy-proven HL treated within the German Hodgkin Study Group trials HD4 to HD15, 10,019 patients underwent central expert pathology review. Eighty-four patients with LDCHL (< 1%) were identified and confirmed.

Epoetin alfa in patients with advanced-stage Hodgkin's lymphoma: results of the randomized placebo-controlled GHSG HD15EPO trial.

Purpose: To determine whether epoetin alfa reduces anemia-related fatigue, improves other aspects of health-related patient-recorded outcomes (PROs), reduces the number of RBC transfusions, and has an impact on freedom from treatment failure (FFTF) and overall survival (OS) in patients with advanced-stage Hodgkin's lymphoma (HL).

Patients And Methods: The prospectively randomized HD15EPO study performed by the German Hodgkin Study Group investigated epoetin alfa administered at doses of 40,000 U weekly during and after chemotherapy (six to eight cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone [BEACOPP]) in a double-blind, placebo-controlled setting. The study accrued 1,379 patients, of whom 1,328 were assessable for safety, 1,303 were assessable for clinical outcome, and 930 were assessable for PROs.

Hodgkin's lymphoma in adolescents treated with adult protocols: a report from the German Hodgkin study group.

PURPOSE The standard of care for adolescent patients with Hodgkin's lymphoma (HL) is undefined, particularly the choice between pediatric and adult protocols. Thus, we compared risk factors and outcome of adolescents and young adults treated within study protocols of the German Hodgkin Study Group (GHSG). PATIENTS AND METHODS Three thousand seven hundred eighty-five patients treated within the GHSG studies HD4 to HD9 were analyzed; 557 patients were adolescents age 15 to 20 years, and 3,228 patients were young adults age 21 to 45 years.

Health-related quality of life during the first year after severe brain trauma with and without polytrauma.

Objective: The increasing number of patients surviving severe traumatic brain injury (sTBI) but with significant sensorimotor and neuropsychological deficits is a challenge to rehabilitation medicine. So far, most research initiatives have focused on mortality rates, physiological or economic parameters to estimate therapeutic effects of rehabilitation strategies. Investigations on health-related quality of life (HRQoL) after TBI with and without concomitant polytrauma are rare compared to other disorders.

Prevalence of anti-erythropoietin antibodies in hemodialysis patients without clinical signs of pure red cell aplasia. Comparison between hypo- and normoresponsive patients treated with epoetins for renal anemia.

Background/aims: The prevalence of anti-erythropoietin antibodies in renal patients without clinical evidence of pure red cell aplasia (PRCA) who respond poorly to epoetin is unknown. This study tested for anti-erythropoietin antibodies in hemodialysis patients who were either hypo- or normoresponsive to epoetin treatment.

Methods: Epoetin hyporesponsiveness (hemoglobin < or =10.

Role of hematotoxicity and sex in patients with Hodgkin's lymphoma: an analysis from the German Hodgkin Study Group.

Purpose: Several scores have described sex as a prognostic factor in patients with Hodgkin's lymphoma (HL). However, little is known how sex-specific factors influence treatment outcome. We systematically investigated sex differences with regard to pretreatment characteristics and therapy-related variables, and examined their influence on the outcome of HL patients.

Lymphocyte-rich classical Hodgkin's lymphoma: clinical presentation and treatment outcome in 100 patients treated within German Hodgkin's Study Group trials.

Purpose: To investigate the clinical characteristics and treatment outcome of patients with lymphocyte-rich classical Hodgkin's lymphoma (LRCHL) compared with other histologic subtypes of Hodgkin's lymphoma (HL).

Patients And Methods: From a total of 2,715 patients with biopsy-proven HL treated within the trials HD7 to HD12 of the German Hodgkin's Study Group, 100 patients (4%) with LRCHL, 145 patients (5%) with lymphocyte-predominant HL (LPHL), 1,688 patients (62%) with nodular sclerosis, 731 patients (27%) with mixed cellularity, and 23 patients (1%) with lymphocyte depletion were identified. Patients with LRCHL had a median age of 38 years (range, 16 to 74 years).

Elevated serum levels of CC thymus and activation-related chemokine (TARC) in primary Hodgkin's disease: potential for a prognostic factor.

The CC thymus and activation-related chemokine (TARC) is a protein, which is highly expressed by Reed-Sternberg cells in Hodgkin's disease and is found in the majority of Hodgkin's disease patients. Within several trials conducted by the German Hodgkin study group, 62 Hodgkin's disease patients were elected based on availability of serum samples post and prior therapy to assess TARC levels by ELISA. TARC levels from 33 patients with continuous complete response (CCR), 20 patients with relapse, and nine patients with progressive disease (PD) were correlated with freedom from treatment failure and survival.

Hodgkin's lymphoma in elderly patients: a comprehensive retrospective analysis from the German Hodgkin's Study Group.

Purpose: With improved prognosis for patients with Hodgkin's lymphoma (HL), interest increasingly focuses on high-risk groups such as elderly patients. We thus performed a retrospective analysis using the German Hodgkin's Study Group (GHSG) database to determine clinical risk factors, course of treatment, and outcome in elderly HL patients in comparison with younger adults.

Patients And Methods: A total of 4,251 patients included in the GHSG studies HD5 to HD9 were analyzed, of whom 372 (8.
