At the authors request, the Editor and Publisher of Cancer Management and Research wish to retract the published article. The authors have informed the journal that no ethical approval was given by the ethics committee of the Institute Review Ethics Committee of Huaihe Hospital of Henan University, despite the article stating such approval had been provided. Given this serious breach of our editorial polices the authors decided to retract the paper.
Our decision-making was informed by our policy on publishing ethics and integrity and the COPE guidelines on retraction.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
