Estrogen has been postulated to contribute to the development and progression of lung cancer. We examined the epidemiologic evidence, explored the characteristics of estrogen receptors (ER) in lung adenocarcinoma, and investigated the effect of estrogen on lung cancer cell migration, including the signaling pathway involved. For epidemiologic evidence, a(More)
Rapidly growing cancer cells secrete growth-promoting polypeptides and have increased proteolytic activity, contributing to tumor progression and metastasis. Their presentation in malignant pleural effusion (MPE) and their predictive value for the outcome of pleurodesis and survival were studied. Between February 2011 and March 2012, MPE samples were(More)
Conventional transbronchial needle aspiration (TBNA) using 19-gauge needles can obtain larger histological specimens for hilar-mediastinal diagnosis. A new 19-gauge eXcelon needle was introduced in Taiwan in July 2012. We prospectively enrolled patients with hilar-mediastinal lesions and pathology results of suspected benign origin or lymphoproliferative(More)
