TA-MUC1 epitope in non-small cell lung cancer
2007
MUC1 (CD227), an established tumor marker, is expressed on glandular epithelia and on epithelial tumors. Tumor MUC1 differs from normal MUC1 by modified glycan side chains. Recently, a novel carbohydrate-induced conformational tumor-associated MUC1 epitope (TA-MUC1) was described, whose clinical relevance in lung cancer is not known. Eighty-five paraffin embedded tissue sections of non-small cell lung cancer (NSCLC) patients (73% male; mean age 64+/-9 years) were stained with the monoclonal antibody PankoMab (against TA-MUC1) and compared with the established antibodies E29 and 214D4 regarding prognostic relevance. TA-MUC1 is virtually absent in bronchial epithelium. As shown by multivariat…
Gemcitabine and docetaxel every 2 weeks in advanced non-small cell lung cancer: a phase II study of the Gruppo Oncologico Italia Meridionale
2002
Abstract Introduction: Platinum-based chemotherapy is the gold standard in advanced non-small cell lung cancer (NSCLC), although with relevant toxic effects. Both docetaxel (DCT) and gemcitabine (GEM) have shown activity as single agent in advanced NSCLC with a different toxicity profile and a lack of cross-resistance. Materials and methods: From April 2000 to May 2001, 47 consecutive patients were enrolled in a multicenter phase II trial. Main inclusion criteria included untreated patients with histologically confirmed NSCLC, age⩽70 years, stage IIIB/IV, Eastern Cooperative Oncology Group performance status (PS) 0–2, measurable disease, adequate hematologic, cardiac, hepatic and renal func…
A randomized, double-blind, placebo-controlled phase 2 study of tigatuzumab (CS-1008) in combination with carboplatin/paclitaxel in patients with che…
2013
Abstract Introduction Tigatuzumab, a humanized monoclonal DR5 agonist antibody induces apoptosis in human cancer cell lines. The objective of this study was to investigate the antitumor effects of tigatuzumab combined with carboplatin/paclitaxel in chemotherapy-naive patients with metastatic/unresectable non-small cell lung cancer (NSCLC). Methods Patients with histologically or cytologically confirmed NSCLC stage IIIB/IV disease by RECIST (version 1.0) and ECOG-PS 0–1 were enrolled at 15 European sites. Patients received tigatuzumab or placebo intravenously with carboplatin/paclitaxel every 3 weeks (1 cycle) for up to 6 cycles. The primary end point was progression-free survival (PFS). Sec…
Severe and uncontrolled adult asthma is associated with vitamin D insufficiency and deficiency
2012
Background Vitamin D has effects on the innate and adaptive immune system. In asthmatic children low vitamin D levels are associated with poor asthma control, reduced lung function, increased medication intake, and exacerbations. Little is known about vitamin D in adult asthma patients or its association with asthma severity and control. Methods Clinical parameters of asthma control and 25-hydroxyvitamin D (25(OH)D) serum concentrations were evaluated in 280 adult asthma patients (mean ± SD: 45.0 ± 13.8 yrs., 40% male, FEV1 74.9 ± 23.4%, 55% severe, 51% uncontrolled). Results 25(OH)D concentrations in adult asthmatics were low (25.6 ±11.8 ng/ml) and vitamin D insufficiency or deficiency (vi…
High-resolution computed tomography quantitation of emphysema is correlated with selected lung function values in stable COPD
2012
<b><i>Background:</i></b> The literature shows conflicting results when high-resolution computed tomography (HRCT) scores of emphysema were correlated with different indices of airflow obstruction. <b><i>Objectives:</i></b> We correlated HRCT scores of emphysema with different indices of airflow obstruction. <b><i>Methods:</i></b> We performed HRCT of the chest in 59 patients, all smokers or ex-smokers, with stable chronic obstructive pulmonary disease of different severity [GOLD stages I–IV; mean age ± SD 67.8 ± 7.3 years; pack/years 51.0 ± 34.6; percent predicted forced expiratory volume in 1 s (FEV<sub>1</su…
Assessment of Lung Cancer Development in Idiopathic Pulmonary Fibrosis Patients Using Quantitative High-Resolution Computed Tomography:A Retrospectiv…
2020
Purpose The purpose of this study was to investigate histogram-based quantitative high-resolution computed tomography (HRCT) indexes in the assessment of lung cancer (LC) development in idiopathic pulmonary fibrosis (IPF) patients. Materials and methods From IPF databases of 2 national respiratory centers, we retrospectively studied patients with and without LC development-respectively, divided into Group A (n=16) and Group B (n=33). The extent of fibrotic disease was quantified on baseline and follow-up HRCT examinations using kurtosis, skewness, percentage of high attenuation area (HAA%), and percentage of fibrotic area (FA%). These indexes were compared between the 2 groups using the Man…
Patterns and predictors of low physical activity in patients with stable COPD: a longitudinal study
2020
Background: Despite the frequency and negative impact of low physical activity among patients with chronic obstructive pulmonary disease (COPD), little is known about how it persists and remits over time or the factors predicting new states of low physical activity. The aim of the study was to determine the probability of a transition between states of low and nonlow physical activity in a cohort of patients with stable COPD followed for 2 years. We also investigated different potentially modifiable factors to determine whether they can predict new states of low physical activity. Methods: We prospectively included 137 patients with stable COPD (mean age 66.9 ± 8.3 years). Physical activity…
Decreased FOXP3 expression in small airways of smokers with COPD
2008
CD4+CD25+ FOXP3-positive T-regulatory cells have an important role in controlling immune and inflammatory reactions. The present authors hypothesise that these cells may be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD). The aim of the present study was to characterise the expression of FOXP3 in large and small airways of nonsmokers, smokers with normal lung function and COPD patients. A total of 19 nonsmokers, 20 smokers with normal lung function and 20 smokers with moderate COPD, undergoing lung resection for a solitary peripheral nonsmall cell carcinoma, were enrolled in the study. Immunohistochemical methods were used to evaluate FOXP3 expression in large a…
Expression of KIT (CD117) in Biphasic Pulmonary Blastoma. Novel Data on Histogenesis
2003
Biphasic pulmonary blastoma (BPB) is a rare primary neoplasm of the lung and its histogenesis is still uncertain. It has been proposed that BPB is derived from mesoderm or endoderm. Others suggested an origin from a single pluripotential cell. We present a case of a BPB with emphasis on expression of the stem cell factor receptor KIT (CD117). We describe a 61-year-old male patient with a BPB of the upper right lobe. Immunohistochemical analysis was performed using a panel of several antibodies including anti-CD117. Strong cytoplasmic expression of CD117 was found in the epithelium (cytokeratin-positive) as well as in the spindle cells (cytokeratin-negative). Expression of CD117 in both mese…
Pre-treatment with mesenchymal stem cells reduces ventilator-induced lung injury
2012
ckground information: Bone marrow-derived mesenchymal stem cells (MSCs) reduce acute lung injury in animals challenged by bleomycin or bacterial lipopolysaccaride. It is not known, however, whether MSCs protect from ventilator- induced lung injury (VILI). Question of the study: Whether MSCs have a potential role in preventing or modulating VILI in healthy rats subjected to high-volume ventilation. Materials and methods: 24 Sprague-Dawley rats (250-300 g) were subjected to high- volume mechanical ventilation (25 ml/kg). MSCs (5x106) were intravenously or intratracheally administered (N=8 each) 30 min before starting over-ventilation and 8 rats were MSC-untreated. Spontaneously breathing anes…
