Postoperative outcome after palliative treatment of malignant pleural effusion.

Background: The objective of this nationwide, registry-based study was to compare the two most frequently used procedures for the palliative treatment of a malignant pleural effusion (MPE) and to evaluate differentiated indications for these two procedures.

Methods: This was a retrospective observational study based on data of the "PLEURATUMOR" registry of the German Society for Thoracic Surgery. Patients who were documented in the period from January 2015 to November 2021 and had video-assisted thoracic surgery (VATS) talc pleurodesis or implantation of an indwelling pleural catheter (IPC) were included.

High Expression of NT5DC2 Is a Negative Prognostic Marker in Pulmonary Adenocarcinoma.

Via immunohistochemistry (IHC) on tissue micro arrays (TMA) clinical and prognostic impact of p53 co-playing 5′-Nucleotidase Domain-Containing Protein 2 (NT5DC2) protein expression was evaluated in 252 NSCLC patients. Confirmatory, gene expression database. mRNA levels of NT5DC2 were studied in 1925 NSCLC patients.

NOP10 predicts lung cancer prognosis and its associated small nucleolar RNAs drive proliferation and migration.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer death worldwide underlining the urgent need for new biomarkers and therapeutic targets for this disease. Long noncoding RNAs are critical players in NSCLC but the role of small RNA species is not well understood. In the present study, we investigated the role of H/ACA box small nucleolar RNAs (snoRNAs) and snoRNA-bound ribonucleoproteins (snoRNPs) in the tumorigenesis of NSCLC.

[Management of Lung Abscess - Diagnostics and Treatment].

Lung abscess is a localized infectious pus-filled cavity of the lung tissue by viral, bacterial, mycotic or parasitic pathogens. Currently, there are different classifications, which are based primarily on the genesis and duration of symptoms. Important steps for diagnosis are in addition to clinical examination, laboratory and chest X-ray especially bronchoscopy with microbiological examinations and computed tomography.

Tumor infiltrating T cells influence prognosis in stage I-III non-small cell lung cancer.

Background: T cell infiltration in non-small cell lung cancer (NSCLC) is essential for the immunological response to malignant tissue, especially in the era of immune-checkpoint inhibition. To investigate the prognostic impact of CD4 T helper cells (T), CD8 cytotoxic (T) and FOXP3 regulatory T (T) cells in NSCLC, we performed this analysis.

Methods: By counterstaining of CD4, CD8 and FOXP3 we used immunohistochemistry on tissue microarrays (TMA) to evaluate peritumoral T cells, T cells and T cells in n=294 NSCLC patients with pTNM stage I-III disease.

Prognostic impact of CD34 and SMA in cancer-associated fibroblasts in stage I-III NSCLC.

Background: Epithelial-to-mesenchymal transition (EMT) is a crucial step in lung cancer pathogenesis. Among others, cancer-associated fibroblasts (CAFs) are reported to regulate this process.

Objectives: To investigate the prognostic and clinical impact, we analyzed CD34+ and SMA+ CAFs in non-small cell lung cancer (NSCLC).

Prostate specific membrane antigen (PSMA) expression in non-small cell lung cancer.

Objectives: PSMA (prostate-specific membrane antigen) is overexpressed in prostate cancer cells and is reported to be a promising target for antibody-based radioligand therapy in patients with metastasized prostate cancer. Since PSMA expression is not restricted to prostate cancer, the underlying study investigates PSMA expression in non-small cell lung cancer (NSCLC).

Material And Methods: Immunohistochemistry was used to identify PSMA expression in n = 275 samples of NSCLC tissue specimens.

Correction: Potential therapeutic impact of CD13 expression in non-small cell lung cancer.

[This corrects the article DOI: 10.1371/journal.pone.

Potential therapeutic impact of CD13 expression in non-small cell lung cancer.

Background: Aminopeptidase N (CD13) is a zinc-binding protease that has functional effects on both cancerogenesis and tumor angiogenesis. Since CD13 is an antigen suitable for molecular targeted therapies (e.g.

Blood group antigen A type 3 expression is a favorable prognostic factor in advanced NSCLC.

Objectives: Several blood group-related carbohydrate antigens are prognosis-relevant markers of tumor tissues. A type 3 (repetitive A) is a blood group antigen specific for A1 erythrocytes. Its potential expression in tumor tissues has so far not been examined.

[Management of Lung Abscess].

A lung abscess is an infectious pulmonary disease characterised by the presence of a pus-filled cavity within the lung parenchyma. The content of an abscess often drains into the airways spontaneously, leading to an air-fluid level visible on chest X-rays and CT scans. Primary lung abscesses occur in patients who are prone to aspiration or in otherwise healthy individuals; secondary lung abscesses typically develop in association with a stenosing lung neoplasm or a systemic disease that compromises immune defences, such as AIDS, or after organ transplantation.

[Tracheotomy - surgical and percutaneous].

Modern indications for tracheostomy are the following: support of mechanical ventilation and weaning from mechanical ventilation, prevention of complications due to prolonged endotracheal tube ventilation. Surgical tracheostomy (ST) still plays an important role in the management of respiratory failure despite the wide use of percutaneous dilatational tracheostomy (PDT). Peri- and postoperative complication rates as well as lethality rates of these competing procedures are similar according to the literature.

Epigenetic dysregulation of KCa 3.1 channels induces poor prognosis in lung cancer.

Epigenomic changes are an important feature of malignant tumors. How tumor aggressiveness is affected by DNA methylation of specific loci is largely unexplored. In genome-wide DNA methylation analyses, we identified the KCa 3.

Management of pleural empyema with single-port video-assisted thoracoscopy.

Objective: The aim of this study was to evaluate the safety and efficacy of an original technique of single-port video-assisted thoracoscopy (S-VATS) for the minimally invasive treatment of pleural empyema in fibrinopurulent stage.

Methods: Single-port video-assisted thoracoscopy was performed under general anesthesia and single-lung ventilation using a 2-cm incision after ultrasound localization of the projected midpoint of the pleural effusion. Through the single access, a video scope and standard thoracoscopy instruments were simultaneously introduced to perform debridement and lavage of the pleural cavity.

Mutations of the EPHB6 receptor tyrosine kinase induce a pro-metastatic phenotype in non-small cell lung cancer.

Alterations of Eph receptor tyrosine kinases are frequent events in human cancers. Genetic variations of EPHB6 have been described but the functional outcome of these alterations is unknown. The current study was conducted to screen for the occurrence and to identify functional consequences of EPHB6 mutations in non-small cell lung cancer.

Prognostic factors of resected node-positive lung cancer: location, extent of nodal metastases, and multimodal treatment.

Objective: To investigate the prognostic significance of location and extent of lymph node metastasis in resected non-small cell lung cancer (NSCLC), and to weigh up the influence of treatment modalities on survival.

Patients And Method: On exploratory analysis, patients were grouped according to location and time of diagnosis of nodal metastasis: group I, pN2-disease in the aortopulmonary region (N=14); group II, pN2-disease at other level (N=30); group III, cN2-disease with response to induction treatment (ypN0; N=21); group IV, cN2-disease without response to induction treatment (ypN1-2; N=27); group V, pN1-disease (N=66).

Results: From 1999 to 2005, 158 patients (median age: 64 years) with node-positive NSCLC were treated at our institution either by neoadjuvant chemo-radiotherapy plus surgery or by surgery plus adjuvant therapy (chemotherapy, radiotherapy, or both).

The long noncoding MALAT-1 RNA indicates a poor prognosis in non-small cell lung cancer and induces migration and tumor growth.

Introduction: The functions of large noncoding RNAs (ncRNAs) have remained elusive in many cases. Metastasis-Associated-in-Lung-Adenocarcinoma-Transcript-1 (MALAT-1) is an ncRNA that is highly expressed in several tumor types.

Methods: Overexpression and RNA interference (RNAi) approaches were used for the analysis of the biological functions of MALAT-1 RNA.
