RETRACTED: 100 years of lung cancer

This article has been retracted at the request of the Editor-in-Chief. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: This article duplicates significant parts of a paper that had already appeared in Am. J. Resp. Crit. Care Med. 172 (2005) 523–529, doi:10.1164/rccm.200504-531OE. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.
