abstract: This article has been withdrawn at the request of the editor. The authors have plagiarized part of a paper that had already appeared in ASCO EDUCATIONAL BOOK (2014), 91-99 (http://meetinglibrary.asco.org/content/114000091-144). 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 an abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
