Stage III N2 non-small cell lung cancer treatment: decision-making among surgeons and radiation oncologists.

Background: Stage III N2 non-small cell lung cancer (NSCLC) is a very heterogeneous disease associated with a poor prognosis. A number of therapeutic options are available for patients with Stage III N2 NSCLC, including surgery [with neoadjuvant or adjuvant chemotherapy (CTx)/neoadjuvant chemoradiotherapy (CRT)] or CRT potentially followed by adjuvant immunotherapy. We have no clear evidence demonstrating a significant survival benefit for either of these approaches, the selection between treatments is not always straightforward and can come down to physician and patient preference.

Image analysis in posttreatment non-small cell lung cancer surveillance: specialists' interpretations reviewed by the thoracic multidisciplinary tumor board.

Background: Data show that the initial specialist's image interpretation and final multidisciplinary tumor board (MTB) assessment can vary substantially in the pretherapeutic cancer setting. The aim of this analysis was to investigate the concordance of the specialist's and MTB's image interpretations in patients undergoing systematic posttreatment lung cancer image surveillance.

Methods: In the initial prospective study, lung cancer patients who had received curative-intent treatment were randomly assigned to undergo either contrast-enhanced computed tomography (CE-CT) or integrated 18-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT).

Comparing Two Imaging Methods for Follow-Up of Lung Cancer Treatment: A Randomized Pilot Study.

Background: Scientific data on the image modality to be used in postcurative treatment surveillance of non-small cell lung cancer patients are scarce. This prospective randomized pilot trial compared the performance of integrated F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and contrast-enhanced computed tomography (CE-CT).

Methods: After termination of curative-intent treatment, patients were randomly assigned to the PET-CT or the CE-CT group.

Curative resection for lung cancer in octogenarians is justified.

Background: Due to an increased life expectancy in a healthy aging population and a progressive incidence of lung cancer, curative pulmonary resections can be performed even in octogenarians. The present study aims to investigate whether surgery is justified in patients reaching the age of 80 years and older who undergo resection for non-small cell lung cancer (NSCLC).

Methods: In this retrospective multi-centre analysis, the morbidity, mortality and long-term survival of 88 patients (24 females) aged ≥80 who underwent complete resection for lung cancer between 2000 and 2013 were analysed.

Pulmonary tularaemia: all that looks like cancer is not necessarily cancer - case report of four consecutive cases.

Background: Pulmonary tularaemia is a very rare disease with only a small number of cases described in the literature. So far, to our knowledge, there exists no case report of pulmonary tularaemia where PET-CT scans and follow up CT scans are available.

Case Presentation: We present four consecutive cases of pulmonary tularaemia.

Lung histology predicts outcome of bronchiolitis obliterans syndrome after hematopoietic stem cell transplantation.

Bronchiolitis obliterans (BO) is a severe complication after allogeneic hematopoietic stem cell transplantation with an unfavorable prognosis. Lung biopsy remains the gold standard for diagnosis. In this retrospective single-center study, we describe 33 patients who underwent biopsy for suspected BO.

Lung resection in hematologic patients with pulmonary invasive fungal disease.

Background: Pulmonary invasive fungal disease is a frequent complication in patients with hematologic malignancies. Surgical resection in addition to antifungal therapy is an option for selected cases but often feared because of immunosuppression.

Methods: We analyzed the outcome of 71 patients undergoing lung resection for pulmonary invasive fungal disease.

Cytokine & chemokine response in the lungs, pleural fluid and serum in thoracic surgery using one-lung ventilation.

Background: Thoracic surgery mandates usually a one-lung ventilation (OLV) strategy with the collapse of the operated lung and ventilation of the non-operated lung. These procedures trigger a substantial inflammatory response. The aim of this study was to analyze the cytokine and chemokine reaction in both lungs, pleural space and blood in patients undergoing lung resection with OLV with special interest in the chemokine growth-regulated peptide alpha (GROα) which is the human equivalent to the rat cytokine-induced neutrophil chemoattractant-1 (CINC-1).

Endoscopic management of bisected hemidiaphragm during retroperitoneoscopic donor nephrectomy.

Retroperitoneoscopy is our preferred technique for renal surgery and is routinely performed for living donor nephrectomy. We report a case of a totally bisected left hemidiaphragm during left-sided retroperitoneoscopic donor nephrectomy. This was most likely caused when creating the retroperitoneal working space by balloon dilation.

Airway epithelium-derived transforming growth factor-beta is a regulator of fibroblast proliferation in both fibrotic and normal subjects.

Background: In the healthy lung, airway epithelial cells (AEC) regulate fibroblast proliferation through release of soluble factors, such as prostaglandins and proteins. Fibroproliferative diseases and airway remodelling may result from an inadequate generation of suppressive factors by AEC or the inability of fibroblasts to respond to them appropriately.

Objective: The aim of this study was to study the effect of primary human AEC on the proliferation of fibroblasts obtained from healthy and fibrotic lungs in an interactive cell culture model.

Induction chemotherapy followed by parenchyma-sparing surgery in medically inoperable NSCLC-results of a feasibility study.

Purpose: Feasibility trial to test the toxicity and outcome of three cycles of induction chemotherapy followed by limited surgery in medically inoperable early stage NSCLC patients.

Patients And Methods: Thirteen patients with NSCLC (stages I-IIIB) with insufficient cardio-respiratory reserves for the oncologically required lung resection, received three cycles of induction chemotherapy with cisplatin (100mg/m(2)) and docetaxel (85mg/m(2)) followed by parenchyma-sparing lung surgery. Operability was evaluated with pulmonary function tests, perfusion scintigraphy and cardiopulmonary exercise testing.

Large cystic tumour at the chest wall mimicking an echinococcosis: a case report.

The authors report an atypical late onset of a big axillary lymphatic malformation in a 41-year-old male. Considering the patient's history and clinical findings at first presentation, the swelling was highly suspicious for malignancy or cystic echinococcosis. A consequent CT showed non infiltrative growth with inhomogeneous density but remained non conclusive regarding diagnosis.

The relevance of surgical therapy for bilateral and/or multiple pulmonary metastases in children.

Purpose: Pulmonary surgery is frequently used for the treatment of metastases in children with various malignant diseases. The benefit of an aggressive surgical treatment in children with bilateral and/or multiple pulmonary metastases is still discussed controversially.

Methods: A retrospective analysis of 10 children (7 girls, 3 boys; age range from 2 to 16.

Cancer/testis antigen expression and specific cytotoxic T lymphocyte responses in non small cell lung cancer.

Non small cell lung cancers (NSCLC) express cancer/testis antigens (CTA) genes and MAGE-A expression correlates with poor prognosis in squamous cell carcinomas. We addressed cytotoxic T lymphocytes (CTL) responses to HLA class I restricted CTA epitopes in TIL from NSCLC in an unselected group of 33 patients consecutively undergoing surgery. Expression of MAGE-A1, -A2, -A3, -A4, -A10, -A12 and NY-ESO-1 CTA genes was tested by quantitative RT-PCR.

Opposite effect of corticosteroids and long-acting beta(2)-agonists on serum- and TGF-beta(1)-induced extracellular matrix deposition by primary human lung fibroblasts.

Asthma and chronic obstructive pulmonary disease (COPD) are characterized by chronic airway inflammation and major structural lung tissue changes including increased extracellular matrix (ECM) deposition. Inhaled corticosteroids and long-acting beta(2)-agonists (LABA) are the basic treatment for both diseases, but their effect on airway remodeling remains unclear. In this study, we investigated the effect of corticosteroids and LABA, alone or in combination, on total ECM and collagen deposition, gene expression, cell proliferation, and IL-6, IL-8, and TGF-beta(1) levels by primary human lung fibroblasts.

Combined transbronchial needle aspiration and positron emission tomography for mediastinal staging of NSCLC.

There are no data available combining transbronchial needle aspiration (TBNA) of mediastinal lymph nodes and positron emission tomography (PET) in the staging of nonsmall cell lung cancer (NSCLC). The aim of the current study was to determine if these two methods can enhance the negative predictive value of the individual modality alone, for a specific lymph node station, and if this integrated approach can reduce the number of mediastinoscopies. A total of 113 patients with enlarged mediastinal lymph nodes (> or = 1 cm), who underwent both TBNA and PET scanning, were included.

Combining bronchoscopy and positron emission tomography for the diagnosis of the small pulmonary nodule < or = 3 cm.

Aim: To assess the role of bronchoscopy and positron emission tomography (PET) scanning in an integrated approach for the diagnosis of noncalcified, small, chest radiologic lesions (< or = 3 cm).

Methods: Seventy-four consecutive patients (29 men; mean age, 64 years) with a pulmonary nodule < or = 3 cm undergoing both combined PET and bronchoscopy were included. When bronchoscopy and PET findings were negative, a multidisciplinary decision was taken to perform further invasive diagnostics or follow-up.

Human bronchial epithelium controls TH2 responses by TH1-induced, nitric oxide-mediated STAT5 dephosphorylation: implications for the pathogenesis of asthma.

Increased levels of NO in exhaled air in association with increased NO synthetase (NOS)2 expression in bronchial epithelial are hallmark features of asthma. It has been suggested that NO contributes to asthma pathogenesis by selective down-regulation of TH1 responses. We demonstrate, however, that NO can reversibly limit in vitro expansion of both human TH1 and TH2 CD4+ T cells.
