Consolidation ALK Tyrosine Kinase Inhibitors Versus Durvalumab or Observation After Chemoradiation in Unresectable Stage III ALK-Positive NSCLC.

Introduction: Patients with advanced ALK-positive NSCLC typically have poor response to immunotherapy; the benefit of consolidation durvalumab in patients with unresectable stage III ALK-positive NSCLC remains unclear. Herein, we compare the efficacy and safety of consolidation ALK tyrosine kinase inhibitor (TKI) versus durvalumab or observation after concurrent chemoradiation.

Methods: We conducted a retrospective study using a multicenter study of 17 institutions globally.

Consolidation Osimertinib Versus Durvalumab Versus Observation After Concurrent Chemoradiation in Unresectable EGFR-Mutant NSCLC: A Multicenter Retrospective Cohort Study.

Introduction: Durvalumab improves survival when used as consolidation therapy after chemoradiation (CRT) in patients with stage III NSCLC. The optimal consolidation therapy for patients with EGFR-mutant (EGFRmut) stage III NSCLC remains unknown.

Methods: In this multi-institutional, international retrospective analysis across 24 institutions, we evaluated outcomes in patients with stage III EGFRmut NSCLC treated with concurrent CRT followed by consolidation therapy with osimertinib, durvalumab, or observation between 2015 and 2022.

Outcome of First-Line Treatment With Pembrolizumab According to KRAS/TP53 Mutational Status for Nonsquamous Programmed Death-Ligand 1-High (≥50%) NSCLC in the German National Network Genomic Medicine Lung Cancer.

Introduction: Programmed death-ligand 1 expression currently represents the only validated predictive biomarker for immune checkpoint inhibition in metastatic NSCLC in the clinical routine, but it has limited value in distinguishing responses. Assessment of KRAS and TP53 mutations (mut) as surrogate for an immunosupportive tumor microenvironment (TME) might help to close this gap.

Methods: A total of 696 consecutive patients with programmed death-ligand 1-high (≥50%), nonsquamous NSCLC, having received molecular testing within the German National Network Genomic Medicine Lung Cancer between 2017 and 2020, with Eastern Cooperative Oncology Group performance status less than or equal to 1 and pembrolizumab as first-line palliative treatment, were included into this retrospective cohort analysis.

Management, risk factors and prognostic impact of checkpoint-inhibitor pneumonitis (CIP) in lung cancer - A multicenter observational analysis.

Introduction: Checkpoint-inhibitor pneumonitis (CIP) represents a major immune-related adverse event (irAE) in patients with lung cancer. We aimed for the clinical characterization, diagnostics, risk factors, treatment and outcome in a large cohort of patients from everyday clinical practice.

Patients And Methods: For this retrospective analysis, 1,376 patients having received checkpoint inhibitors (CPI) in any line of therapy from June 2015 until February 2020 from three large-volume lung cancer centers in Berlin, Germany were included and analyzed.

Recurrence patterns and impact of brain metastases in synchronous single organ oligometastatic lung cancer following local ablative treatment - A multicenter analysis.

Introduction: Local ablative therapy (LAT) improves survival in oligometastatic lung cancer (OMD), but there is limited information on recurrence patterns, re-treatments and in particular the role of brain metastases during the course of disease. We therefore conducted a retrospective multicenter analysis to evaluate course of disease, sequence of therapies and predictors for long-term disease-control in the brain and survival endpoints.

Patients And Methods: Clinical data of patients with synchronous, single organ OMD with ≤4 metastases were collected from 5 certified German lung cancer centers.

The impact of TP53 co-mutations and immunologic microenvironment on outcome of lung cancer with EGFR exon 20 insertions.

Background: EGFR exon20 insertions (ex20ins) are targeted by novel compounds in non-small-cell lung cancer (NSCLC). However, data about outcome under conventional therapies and the influence of molecular features are scarce.

Patients And Methods: We retrospectively analysed 118 patients with evaluation of radiologic response based on RECIST v1.

KRAS/TP53 co-mutations identify long-term responders to first line palliative treatment with pembrolizumab monotherapy in PD-L1 high (≥50%) lung adenocarcinoma.

Background: Pembrolizumab is a standard of care as first line palliative therapy in PD-L1 overexpressing (≥50%) non-small cell lung cancer (NSCLC). This study aimed at the identification of KRAS and TP53-defined mutational subgroups in the PD-L1 high population to distinguish long-term responders from those with limited benefit.

Methods: In this retrospective, observational study, patients from 4 certified lung cancer centers in Berlin, Germany, having received pembrolizumab monotherapy as first line palliative treatment for lung adenocarcinoma (LuAD) from 2017 to 2018, with PD-L1 expression status and targeted NGS data available, were evaluated.

Epigenomic profiling of non-small cell lung cancer xenografts uncover LRP12 DNA methylation as predictive biomarker for carboplatin resistance.

Background: Non-small cell lung cancer (NSCLC) is the most common cause of cancer-related deaths worldwide and is primarily treated with radiation, surgery, and platinum-based drugs like cisplatin and carboplatin. The major challenge in the treatment of NSCLC patients is intrinsic or acquired resistance to chemotherapy. Molecular markers predicting the outcome of the patients are urgently needed.

Clinicopathological Characteristics of RET Rearranged Lung Cancer in European Patients.

Introduction: Rearrangements of RET are rare oncogenic events in patients with non-small cell lung cancer (NSCLC). While the characterization of Asian patients suggests a predominance of nonsmokers of young age in this genetically defined lung cancer subgroup, little is known about the characteristics of non-Asian patients. We present the results of an analysis of a European cohort of patients with RET rearranged NSCLC.

Secondary Malignancies Following Treatment for Hodgkin's Lymphoma in Childhood and Adolescence.

Background: About 155 persons under age 18 develop Hodgkin's lymphoma (HL) in Germany every year. More than 90% survive at least 20 years. They may, however, suffer from late sequelae of treatment, including secondary malignant neoplasia (SMN).

The impact of central review and central therapy planning on the treatment of children and adolescents with Hodgkin lymphoma.

Purpose: The multicentre response-adapted paediatric Hodgkin lymphoma trial GPOH-HD95 (1995-2001, 925 patients) was followed by the 'HD-Interval' period (2001-2002, 203 patients). During this period, treatment was recommended according to GPOH-HD95 protocol with only minor changes. Central review and treatment planning as in HD95, however, had to be omitted in the absence of funding.

A rapid and efficient way to manage hyponatremia in patients with SIADH and small cell lung cancer: treatment with tolvaptan.

Background: Hyponatremia based on syndrome of inappropriate antidiuretic hormone hypersecretion (SIADH) is observed in up to 15% of patients with small cell lung cancer (SCLC). The electrolyte imbalance is associated with a high morbidity and mortality and often delays appropriate treatment. Management of hyponatremia proved to be challenging until new vasopressin-2 receptor antagonists such as tolvaptan became available.

Treatment of children and adolescents with Hodgkin lymphoma without radiotherapy for patients in complete remission after chemotherapy: final results of the multinational trial GPOH-HD95.

Unlabelled: PURPOSE To minimize the risk of late effects in pediatric Hodgkin lymphoma (HL) by omitting radiotherapy (RT) in patients in complete remission (CR) after chemotherapy and reducing the standard radiation dose to 20 Gy in patients in incomplete remission.

Patients And Methods: Between 1995 and 2001, 925 patients with classical HL (cHL) were registered from seven European countries in German Society of Pediatric Oncology and Hematology Hodgkin Lymphoma Trial 95. Patients in treatment group 1 (TG1; early stages) received two cycles of vincristine, prednisone, procarbazine, and doxorubicin or vincristine, prednisone, etoposide, and doxorubicin chemotherapy; additional two or four cycles of cyclophosphamide, vincristine, prednisone, and procarbazine were added in TG2 (intermediate stages) or TG3 (advanced stages), respectively.

Salvage therapy of progressive and recurrent Hodgkin's disease: results from a multicenter study of the pediatric DAL/GPOH-HD study group.

Purpose: To evaluate a salvage therapy (ST-HD-86) for patients with progressive and relapsed Hodgkin's disease after primary treatment in the pediatric DAL/GPOH studies. The essential chemotherapeutic regimens were ifosfamide, etoposide, and prednisone (IEP) and doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).

Methods: One hundred seventy-six patients with progression (n = 51) or first relapse (n = 125) were enrolled by 67 centers.

Proliferation characteristics in pediatric Hodgkin's lymphoma point to a cell cycle arrest in the G(1) phase.

This study was undertaken to determine the prognostic relevance of the proliferation rate in neoplastic cells in children and adolescents with Hodgkin's lymphoma. Paraffin-embedded biopsy specimens were immunostained with the proliferation-associated monoclonal antibodies Ki-S5 (Ki-67 antigen) and Ki-S2 (which detects the repp86 protein). Repp86 is a protein of about 100 kDa encoded by a gene located on human chromosome band 20q11.

Impact of latent Epstein-Barr virus infection on outcome in children and adolescents with Hodgkin's lymphoma.

Purpose: The prognostic significance of latent Epstein-Barr virus (EBV) infection in Hodgkin's lymphoma (HL) is debated controversially. Especially in the pediatric age group, no conclusive data are available.

Patients And Methods: Eight hundred forty-two children and adolescents (median age, 13.
