篡改實驗數據,直接創造新概念,最終被撤稿!
學術界最惡劣的造假案誕生:
精準醫療(Precision Medicine,PM)是一種醫療模型,可根據個人患者的具體情況制定醫療決策,治療,實踐或產品,從而提出醫療保健的個性化要求。更通俗的講,精準醫療是一種將個人基因、環境與生活習慣差異考慮在內的疾病預防與處置的新興方法。
在2006年,杜克大學Anil Potti的團隊在國際頂級醫學期刊新英格蘭醫學雜志NEJM,JAMA 及Nature Medicine 等雜志上發表了幾篇論文,報道某些基因表達特征預示了患者對化學療法的反應,這也算是精準醫療的萌芽。但是,很快兩名外部生物統計學家就對該研究提出了擔憂。
2010年,杜克大學(Duke)決定讓Anil Potti休假,并根據他的工作暫停了三項臨床試驗。
幾個月后,Potti辭職了。后來,Potti的眾多頂級研究成果都被撤回,杜克大學在臨床試驗中面臨患者提起的訴訟,這直接導致杜克大學卷入了學術不端的漩渦。
2015年,根據杜克大學的調查和ORI的審查,官方得出結論,Anil Potti在資助申請,提交的手稿和9篇研究論文中包含了虛假的研究數據。除其他問題外,Potti更篡改了數據集,以使藥物反應預測變量看起來更準確。
到2021年4月15日,Anil Potti被撤回了NEJM,JAMA,Nature Medicine,PNAS 等14篇文章,同時更正了PNAS,JCO 等7篇文章。

?臨床試驗僅招募了4名患者,而且對于達沙替尼的治療都不應答,但是在Anil Potti的研究結果報告中指出:33名患者中有6名對達沙替尼呈陽性反應;
?Anil Potti更改了數據集,以提高治療反應的預測指標的準確性:在提交給臨床癌癥研究的手稿中,Anil Potti逆轉了133名受試者中24名阿霉素預測因子的反應者狀態;并更改了89個樣本中46個的癌癥復發表型;
到2021年4月15日,Anil Potti被撤回了NEJM,JAMA,Nature Medicine,PNAS 等14篇文章,同時更正了PNAS,JCO 等7篇文章。具體撤稿及糾正的文章如下:
