The Editors-in-Chief have retracted this article. After publication concerns were raised that there were discrepancies in the reporting of the number of NACT cycles the patients underwent. The authors were given the opportunity to provide an explanation but have not responded to any correspondence regarding this matter. The Editors-in-Chief therefore no longer have confidence in the results presented.

Li Yuan, Jian-Jun Li, Chang-Qing Li, Cheng-Gong Yan, Ze-Long Cheng, Yuan-Kui Wu, Peng Hao, Bing-Quan Lin and Yi-Kai Xu have not responded to any correspondence from the editor/publisher about this retraction.
