Jon Sudbø (born May 3, 1961) is a Norwegian dentist, physician, and former medical researcher, who was exposed as a scientific fraudster in 2006. Over a period of several years, he fabricated results in the field of oncology which he published in leading medical journals. The article that led to his downfall, which was published in ''The Lancet'', was based on 900 patients Sudbø had fabricated entirely. The editor of ''The Lancet'' described this as the biggest scientific fraud conducted by a single researcher ever.〔http://www.denstoredanske.dk/Krop,_psyke_og_sundhed/Sundhedsvidenskab/Læger/Jon_Sudbø〕 Sudbø was formerly employed as a consultant oncologist at the Radium Hospital in Oslo and as an associate professor at the University of Oslo, but as a result of the fabrication scandal, he resigned from these positions in 2006. The same year, his licenses to practice medicine and dentistry were revoked. An inquiry by the Faculty of Medicine at the University of Oslo found that most of Sudbø's work, including his doctoral dissertation, were based on fraud, and the University of Oslo revoked his doctorate in medicine in 2006. In 2007, he was granted a strictly limited license to work as an assistant dentist under supervision, and in 2009, he regained licenses to practice medicine and dentistry with some restrictions. He is currently working as an assistant dentist in Seljord, Telemark. His wife Wanja Kildal was his co-author of 7 of the articles that were found to be fraudulent and subsequently retracted, while his brother Asle Sudbø was a co-author of two of these articles. ==Scandal== In January 2006 it was revealed that his October 2005 fast track submission to ''The Lancet'' was based upon fraudulent patient data. The article had suggested that non-COX2-NSAIDs like ibuprofen diminish the risk of oral cancer in smokers. However, it turned out that the whole patient material was fictional. The leader of the epidemiology division at Norwegian Institute of Public Health, Camilla Stoltenberg, found the article suspicious at the end of 2005 because the data was supposedly from a cancer patient database which had not yet opened. The Norwegian newspaper ''Dagbladet'' reported that of the 908 subjects in the Lancet study 250 had the same birthday. Sudbø has later acknowledged that he has used fictional data in at least two more papers, published in the ''New England Journal of Medicine'' and the ''Journal of Clinical Oncology''. An independent Commission of Inquiry led by Swedish Professor Anders Ekbom, that also included a member from the U.S. National Cancer Institute, was set up by Rikshospitalet and the University of Oslo to discern the details of the fraud. They were also to try to identify the role of the co-authors, which included, among others, Jon Sudbø's brother and wife. In May 2006, Norwegian and Swedish media reported that the committee was investigating some 60 scientists from 6 countries, and a total of 38 articles. The commission reported on 30 June 2006.〔http://www.rikshospitalet.no/view/readavdi.asp?nPubID=6628&department=English〕 The commission deemed much of Sudbø's work invalid because of manipulation and fabrication of raw data: of the 38 articles he had published since 1993, 15 were condemned as fraudulent, including his doctoral dissertation. Because of this, the dissertation and the other fraudulent articles will be rescinded. The commission also criticised the co-authors of Sudbø's papers. Professor Anders Ekbom, the Chair of the Commission, said: "One explanation of this catastrophe was that Sudbø was a lone wolf. Few or anyone had insight into his work". However, the commission found no evidence that any of his co-authors had taken part in the fraud or otherwise been party to the deceit (although Sudbø's supervisor accepted criticism for lack of vigilance and follow-up). In November 2006 his authorizations as a physician and a dentist were revoked by the Norwegian Board of Health Supervision, but in 2007 he was granted a strictly limited authorization to work as an assistant dentist. In 2009 he was granted restricted authorizations to practice as dentist and as a physician, however he cannot involve himself in research. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jon Sudbø」の詳細全文を読む スポンサード リンク
