OBJECTIVES Recent studies indicated that estrogens may influence the development of non-small cell lung cancer (NSCLC). The 17-beta-hydroxysteroid dehydrogenase type 1 (HSD17B1) catalyzes the reduction of estrone (E1) to the highly potent E2. Although the significance of aromatase in an intratumoral E2 production in NSCLC is well established, the role of(More)
Recent studies have associated oestrogen metabolism and cigarette smoking with their carcinogenic impact on the lungs. Compounds commonly found in tobacco smoke induce the activity of CYP1B1, the enzyme responsible for the synthesis of catecholic derivatives of oestrogens. During their redox transformations, these structures can release large amounts of(More)
Recent studies indicated undisputed contribution of connective tissue growth factor (CTGF) in the development of many cancers, including non-small cell lung cancer (NSCLC). However, the functional role and regulation of CTGF expression during tumorigenesis remain elusive. Our goal was to determine CTGF transcript and protein levels in tumoral and matched(More)
BACKGROUND The aim of this study was a comparison of early and late results in surgical treatment of funnel chest using the Nuss method in patients in various age groups to find the optimal age to perform the corrective procedure. METHODS Six hundred eighty patients operated on from June 2002 to October 2012 were included in the retrospective analysis.(More)
It has been demonstrated that estrogens are able to enhance lung tumorigenesis by estrogen receptor (ER) pathway. ER signaling is a highly complex process that requires a number of different coactivators, including proline-, glutamic acid- and leucine-rich protein-1 (PELP1). We studied PELP1 transcript and protein levels in cancerous and histopathologically(More)
INTRODUCTION The selection of treatment for local recurrence in patients with non-small-cell lung cancer (NSCLC) depends on the possibility of performing a radical tumor resection, the patient's performance status, and cardiopulmonary efficiency. Compared with chemoradiotherapy, surgical treatment offers a greater chance of long-term survival, but results(More)
