[Prevention, Diagnosis, Therapy, and Follow-up of Lung Cancer - Interdisciplinary Guideline of the German Respiratory Society and the German Cancer Society - Abridged Version].

The current S3 Lung Cancer Guidelines are edited with fundamental changes to the previous edition based on the dynamic influx of information to this field:The recommendations include de novo a mandatory case presentation for all patients with lung cancer in a multidisciplinary tumor board before initiation of treatment, furthermore CT-Screening for asymptomatic patients at risk (after federal approval), recommendations for incidental lung nodule management , molecular testing of all NSCLC independent of subtypes, EGFR-mutations in resectable early stage lung cancer in relapsed or recurrent disease, adjuvant TKI-therapy in the presence of common EGFR-mutations, adjuvant consolidation treatment with checkpoint inhibitors in resected lung cancer with PD-L1 ≥ 50%, obligatory evaluation of PD-L1-status, consolidation treatment with checkpoint inhibition after radiochemotherapy in patients with PD-L1-pos. tumor, adjuvant consolidation treatment with checkpoint inhibition in patients withPD-L1 ≥ 50% stage IIIA and treatment options in PD-L1 ≥ 50% tumors independent of PD-L1status and targeted therapy and treatment option immune chemotherapy in first line SCLC patients.Based on the current dynamic status of information in this field and the turnaround time required to implement new options, a transformation to a "living guideline" was proposed.

Nonintubated versus Intubated Lung Volume Reduction Surgery in Patients with End-Stage Lung Emphysema and Hypercapnia.

Lung volume reduction surgery (LVRS) represents an important treatment option in carefully selected patients with end-stage lung emphysema. The aim of this study was to assess the efficacy and safety of nonintubated LVRS compared to intubated LVRS in patients with preoperative hypercapnia and lung emphysema. Between April 2019 and February 2021, n = 92 patients with end-stage lung emphysema and preoperative hypercapnia undergoing unilateral video-assisted thoracoscopic LVRS (VATS-LVRS) performed in epidural anesthesia and mild sedation (nonintubated, group 1) or conventional general anesthesia (intubated, control, group 2) were prospectively enrolled in this study.

NSCLC with uncommon EGFR mutations treated with atezolizumab plus bevacizumab and chemotherapy.

Objectives: For refractory NSCLC patients with EGFR mutations, recent studies have demonstrated a favorable response to the combination of anti-angiogenic therapy and checkpoint inhibition but included only very few patients with uncommon EGFR mutations for which treatment options are still limited despite new targeted treatments.

Materials And Methods: Sixteen stage IV NSCLC patients with uncommon EGFR mutations from 9 different German centers were treated in first or further line with Atezolizumab, Bevacizumab, Carboplatin and (nab-)Paclitaxel (ABCP). PFS was evaluated from start of ABCP and OS from time of initial diagnosis of stage IV.

Lung Volume Reduction Surgery Reduces Pulmonary Arterial Hypertension Associated With Severe Lung Emphysema and Hypercapnia.

Lung volume reduction surgery (LVRS) represents a standard surgical approach for patients with severe pulmonary emphysema. One of the relevant risk factors for LVRS is the presence of pulmonary arterial hypertension (PAH). The aim of this study is to assess the postoperative changes in pulmonary arterial pressure (PAP) after LVRS for patients with severe pulmonary emphysema compared with preoperative measures.

International Tailored Chemotherapy Adjuvant (ITACA) trial, a phase III multicenter randomized trial comparing adjuvant pharmacogenomic-driven chemotherapy versus standard adjuvant chemotherapy in completely resected stage II-IIIA non-small-cell lung cancer.

Background: Several strategies have been investigated to improve the 4% survival advantage of adjuvant chemotherapy in early-stage non-small-cell lung cancer (NSCLC). In this investigator-initiated study we aimed to evaluate the predictive utility of the messenger RNA (mRNA) expression levels of excision repair cross complementation group 1 (ERCC1) and thymidylate synthase (TS) as assessed in resected tumor.

Patients And Methods: Seven hundred and seventy-three completely resected stage II-III NSCLC patients were enrolled and randomly assigned in each of the four genomic subgroups to investigator's choice of platinum-based chemotherapy (C, n = 389) or tailored chemotherapy (T, n = 384).

[Successful treatment of a geriatric COVID-19 patient with severe chest trauma : An interdisciplinary case report].

The coronavirus disease 2019 (COVID-19) has spread rapidly worldwide and leads to high morbidity and mortality. Clinical experience regarding the surgical management in COVID-19 patients is limited. We report the interdisciplinary approach in a COVID-19 patient with severe thoracic trauma and pulmonary symptoms, who was admitted to the emergency unit after blunt chest trauma with dislocated serial rib fractures and concomitant hemothorax.

Molecular approach to the classification of chronic fibrosing lung disease-there and back again.

Chronic diffuse parenchymal lung disease (DPLD) is an umbrella term for a very heterogeneous group of lung diseases. Over the last decades, clinical, radiological and histopathological criteria have been established to define and separate these entities. More recently the clinical utility of this approach has been challenged as a unifying concept of pathophysiological mechanisms and a shared response to therapy across the disease spectrum have been described.

Veno-Venous Extracorporeal Lung Support as a Bridge to or Through Lung Volume Reduction Surgery in Patients with Severe Hypercapnia.

Extracorporeal lung support (ECLS) represents an essential support tool especially for critically ill patients undergoing thoracic surgical procedures. Lung volume reduction surgery (LVRS) is an important treatment option for end-stage lung emphysema in carefully selected patients. Here, we report the efficacy of veno-venous ECLS (VV ECLS) as a bridge to or through LVRS in patients with end-stage lung emphysema and severe hypercapnia.

Healthcare resource utilization and associated cost analysis of the PROCLAIM study in patients with stage III non-small-cell lung cancer.

To analyze patient-reported swallowing difficulties, healthcare resource utilization and associated costs during the PROCLAIM study. Patients with stage III non-squamous non-small cell lung cancer received pemetrexed-cisplatin (PemCis) combined with concurrent thoracic radiotherapy followed by consolidation pemetrexed, or concurrent chemoradiotherapy with etoposide-cisplatin (EtoCis) followed by standard consolidation chemotherapy. Patient - reported swallowing function was measured using diaries.

A randomized, phase 2 evaluation of the CHK1 inhibitor, LY2603618, administered in combination with pemetrexed and cisplatin in patients with advanced nonsquamous non-small cell lung cancer.

This phase 2 portion of a phase 1/2 study examined the efficacy and safety of LY2603618, a selective checkpoint kinase 1 inhibitor, combined with pemetrexed and cisplatin (LY+Pem+Cis) in patients with advanced nonsquamous non-small cell lung cancer (NSCLC). This multicenter, randomized, controlled, open-label study (NCT01139775) enrolled patients with stage IV nonsquamous NSCLC and an Eastern Cooperative Oncology Group performance status ≤1. Patients were randomized (2:1) to LY+Pem+Cis or pemetrexed and cisplatin (Pem+Cis).

Single-Site Cannulation Venovenous Extracorporeal CO2 Removal as Bridge to Lung Volume Reduction Surgery in End-Stage Lung Emphysema.

Lung volume reduction surgery (LVRS) is an important treatment option for end-stage lung emphysema in carefully selected patients. Here, we first describe the application of low-flow venovenous extracorporeal CO2 removal (LFVV-ECCO2R) as bridge to LVRS in patients with end-stage lung emphysema experiencing severe hypercapnia caused by acute failure of the breathing pump. Between March and October 2015, n = 4 patients received single-site LFVV-ECCO2R as bridge to LVRS.

Inhalative steroids as an individual treatment in symptomatic lung cancer patients with radiation pneumonitis grade II after radiotherapy - a single-centre experience.

Purpose: To assess efficacy of our single-centre experience with inhalative steroids (IS) in lung cancer patients with symptomatic radiation pneumonitis (RP) grade II.

Material And Methods: Between 05/09 and 07/10, 24 patients (female, n = 8; male, n = 16) with lung cancer (non-small cell lung carcinoma [NSCLC]: n = 19; small cell lung cancer [SCLC]: n = 3; unknown histology: n = 2) and good performance status (ECOG ≤1) received definitive radiotherapy to the primary tumour site and involved lymph nodes with concurrent chemotherapy (n = 18), sequential chemotherapy (n = 2) or radiation only (n = 4) and developed symptomatic RP grade II during follow-up. No patient presented with oxygen requiring RP grade III.

GILT--A randomised phase III study of oral vinorelbine and cisplatin with concomitant radiotherapy followed by either consolidation therapy with oral vinorelbine and cisplatin or best supportive care alone in stage III non-small cell lung cancer.

Background: Concurrent chemoradiotherapy (CRT) is considered standard for inoperable stage III non-small cell lung cancer (NSCLC). Consolidation chemotherapy (CC) following CRT is intended to further improve outcomes, yet studies have shown discordant results. This phase III study assessed CRT followed by best supportive care (BSC) or consolidation with oral vinorelbine and cisplatin.

CD4 T cells are required for both development and maintenance of disease in a new mouse model of reversible colitis.

Current therapies to treat inflammatory bowel diseases have limited efficacy, significant side effects, and often wane over time. Little is known about the cellular and molecular mechanisms operative in the process of mucosal healing from colitis. To study such events, we developed a new model of reversible colitis in which adoptive transfer of CD4(+)CD45RB(hi) T cells into Helicobacter typhlonius-colonized lymphopenic mice resulted in a rapid onset of colonic inflammation that was reversible through depletion of colitogenic T cells.

Intraoperative veno-venous extracorporeal lung support in thoracic surgery: a single-centre experience.

Objectives: Intraoperative extracorporeal lung support (ECLS) during thoracic surgical procedures is a modern concept that is gaining increasing acceptance. So far, cardiopulmonary bypass (CPB), veno-arterial extracorporeal membrane oxygenation (v-a-ECMO) or pumpless arterio-venous interventional lung assist (iLA) were utilized for intraoperative support. Only a few case reports have described the use of veno-venous ECMO for intraoperative ECLS.

Single site cannulation veno-venous extracorporeal lung support during pulmonary resection in patients with severely compromised pulmonary function.

The intraoperative application of extracorporeal lung support devices during thoracic surgical procedures represents a modern concept with promising results. So far, pumpless extracorporeal interventional lung assist and veno-venous or veno-arterial extracorporeal membrane oxygenation via dual cannulation were utilized for complete or partial lung support throughout the surgical procedure. We report the initial intraoperative application of low-flow singular double-lumen veno-venous-extracorporeal membrane oxygenation for extracorporeal lung support during lung resections in patients with severely impaired preoperative pulmonary function.

Efficacy of the irreversible ErbB family blocker afatinib in epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI)-pretreated non-small-cell lung cancer patients with brain metastases or leptomeningeal disease.

Introduction: Afatinib is an effective first-line treatment in patients with epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC) and has shown activity in patients progressing on EGFR-tyrosine kinase inhibitors (TKIs). First-line afatinib is also effective in patients with central nervous system (CNS) metastasis. Here we report on outcomes of pretreated NSCLC patients with CNS metastasis who received afatinib within a compassionate use program.

Preclinical analyses and phase I evaluation of LY2603618 administered in combination with pemetrexed and cisplatin in patients with advanced cancer.

LY2603618 is an inhibitor of checkpoint kinase 1 (CHK1), an important regulator of the DNA damage checkpoints. Preclinical experiments analyzed NCI-H2122 and NCI-H441 NSCLC cell lines and in vitro/in vivo models treated with pemetrexed and LY2603618 to provide rationale for evaluating this combination in a clinical setting. Combination treatment of LY2603618 with pemetrexed arrested DNA synthesis following initiation of S-phase in cells.

The liver may act as a firewall mediating mutualism between the host and its gut commensal microbiota.

A prerequisite for establishment of mutualism between the host and the microbial community that inhabits the large intestine is the stringent mucosal compartmentalization of microorganisms. Microbe-loaded dendritic cells trafficking through lymphatics are arrested at the mesenteric lymph nodes, which constitute the firewall of the intestinal lymphatic circulation. We show in different mouse models that the liver, which receives the intestinal venous blood circulation, forms a vascular firewall that captures gut commensal bacteria entering the bloodstream during intestinal pathology.

TREM-1 deficiency can attenuate disease severity without affecting pathogen clearance.

Triggering receptor expressed on myeloid cells-1 (TREM-1) is a potent amplifier of pro-inflammatory innate immune reactions. While TREM-1-amplified responses likely aid an improved detection and elimination of pathogens, excessive production of cytokines and oxygen radicals can also severely harm the host. Studies addressing the pathogenic role of TREM-1 during endotoxin-induced shock or microbial sepsis have so far mostly relied on the administration of TREM-1 fusion proteins or peptides representing part of the extracellular domain of TREM-1.

Severe ARDS induced by fusobacterial infections: a rare clinical presentation of Lemierre syndrome.

Acute respiratory distress syndrome (ARDS) poses a major challenge in intensive care settings. The main underlying causes of ARDS are trauma, pancreatitis, and pulmonary manifestation of systemic inflammatory response syndrome/sepsis.Lemierre syndrome represents a nearly forgotten entity arising from oropharyngeal infections with Fusobacterial species, and it is of renewed and increasing interest because of evolving antibiotic resistances.

Immature murine NKT cells pass through a stage of developmentally programmed innate IL-4 secretion.

We assessed the production of the canonical Th2 cytokine IL-4 by NKT cells directly in vivo using IL-4-substituting strains of reporter mice that provide faithful and sensitive readouts of cytokine production without the confounding effects of in vitro stimulation. Analysis in naïve animals revealed an "innate" phase of IL-4 secretion that did not need to be triggered by administration of a known NKT cell ligand. This secretion was by immature NKT cells spanning Stage 1 of the maturation process in the thymus (CD4(+) CD44(lo) NK1.
