Clinical Impact of Endoscopic Ultrasound-Fine Needle Aspiration of Left Adrenal Masses in Established or Suspected Lung Cancer
IntroductionCorrect lung cancer staging is pivotal for optimal allocation to surgical and nonsurgical treatment. A left adrenal gland (LAG) mass is found in 5 to 16%, and malignancy preclude surgery. Endoscopic ultrasound (EUS) is superior to other imaging procedures in visualizing LAG, but the impact of EUS-fine needle aspiration (FNA) on tumor, node, metastasis (TNM)-staging, treatment, and survival is unknown.MethodsThe impact of EUS-FNA of the LAG on TNM staging, treatment, and survival was evaluated retrospectively in all patients (n = 40) referred to EUS during 2000–2006 for known or suspected lung cancer and where EUS disclosed an enlarged LAG. Conventional workup had preceded EUS.ResultsEUS-FNA of an enlarged LAG altered the TNM staging in 70% (downstaged: 26 of 28 patients) and treatment in 48% (gained surgery 25%, avoided surgery 5%, surgically verified benign disease 5%, no cancer and no further workup 5%, and no cancer, control computed tomography, and then no further workup 8%). A malignant LAG lesion was found in 28% and was significantly associated with shorter survival.ConclusionEUS-FNA of an enlarged LAG in patients with known or suspected lung cancer had a significant impact on TNM staging, treatment, and survival. The impact of routine visualization of the LAG in lung cancer workup needs to be prospectively validated

The Danish randomized lung cancer CT screening trial:overall design and results of the prevalence round
Introduction:Lung cancer screening with low dose computed tomography (CT) has not yet been evaluated in randomized clinical trials, although several are underway.Methods:In The Danish Lung Cancer Screening Trial, 4104 smokers and previous smokers from 2004 to 2006 were randomized to either screening with annual low dose CT scans for 5 years or no screening. A history of cigarette smoking of at least 20 pack years was required. All participants have annual lung function tests, and questionnaires regarding health status, psychosocial consequences of screening, smoking habits, and smoking cessation.Baseline CT scans were performed in 2052 participants. Pulmonary nodules were classified according to size and morphology: (1) Nodules smaller than 5 mm and calcified (benign) nodules were tabulated, (2) Noncalcified nodules between 5 and 15 mm were rescanned after 3 months. If the nodule increased in size or was larger than 15 mm the participant was referred for diagnostic workup.Results:At baseline 179 persons showed noncalcified nodules larger than 5 mm, and most were rescanned after 3 months: The rate of false-positive diagnoses was 7.9%, and 17 individuals (0.8%) turned out to have lung cancer. Ten of these had stage I disease. Eleven of 17 lung cancers at baseline were treated surgically, eight of these by video assisted thoracic surgery resection.Conclusions:Screening may facilitate minimal invasive treatment and can be performed with a relatively low rate of false-positive screen results compared with previous studies on lung cancer screening
