BACKGROUND There is increasing evidence that suggests that particular histopathologic types of non-small-cell lung cancer (NSCLC) display distinct molecular characteristics. We analyzed, in lung squamous cell carcinoma (SCC) and adenocarcinoma (AC), the expression of 8 genes that constitute 2 previously reported prognostic expression signatures in NSCLC. (More)
INTRODUCTION High thoracic epidural anesthesia (TEA) causes blockade of sympathetic fibers involved in innervation of the heart (segments T1-T4), which results in changes of cardiac electrophysiology. The anti-arrhythmic effects of TEA on supraventricular arrhythmias, mainly atrial fibrillation, are controversial. THE AIM OF THE STUDY The aim of the study(More)
Bronchial stump fistula (BSF) is a known complication after lobectomy, although its incidence after lobe resection for non-small cell lung cancer usually does not exceed 2%. We present the case of a patient in whom a late BSF developed that led to a fatal pulmonary hemorrhage 4 weeks after right upper lobectomy and 4 hours after emergency readmission. Such(More)
PURPOSE Molecular features of non-small cell lung cancer (NSCLC) in never-smokers are not well recognized. We assessed the expression of genes potentially related to lung cancer etiology in smoking vs. never-smoking NSCLC patients. METHODS We assayed frozen tumor samples from surgically resected 31 never-smoking and 54 clinically pair-matched smoking(More)
OBJECTIVES Low-dose computed tomography (LDCT) screening improves lung cancer prognosis but also results in diagnostic work-up and surgical treatment in many individuals without cancer. Therefore, we analysed the procedures that screening participants underwent to better understand the extent of overdiagnosis. METHODS Between 2009 and 2011, 8649 healthy(More)
1. Prolongation of the QT interval is associated with a risk of life-threatening cardiac arrhythmias. In the present study, we examined whether reversible blockade of preganglionic sympathetic fibres of the heart, achieved by thoracic epidural anaesthesia, affects cardiac repolarization and thus confers an anti-arrhythmic effect. 2. Fifty-two men, aged(More)
OBJECTIVES AND METHODS To evaluate the results of thymectomy in myasthenia gravis we performed retrospective analysis of 82 consecutive patients in the mean age of 39 +/- 15 treated between 1991 and 2001. All patients underwent extended thymectomy by median sternotomy. Follow-up was assessed in 74 of 81(91.4%) patients, in the mean age of 39 +/- 15,(More)
OBJECTIVES Anatomical lobar resection and mediastinal lymphadenectomy remain the standard for the treatment of early stage non-small-cell lung cancer (NSCLC) and are preferred over procedures such as segmentectomy or wedge resection. However, there is an ongoing debate concerning the influence of the extent of the resection on overall survival. The aim of(More)
