We read with interest the article entitled ‘Borderline resectable pancreatic cancer: conceptual evolution and current approach to image-based classification’ published in the Annals of Oncology, in April 2017, by Gilbert et al. [1]. The review extensively discusses the major controversies concerning borderline resectable pancreatic cancer (BRPC): lack of universally agreed definition, variance in institution-by-institution practice, and lack of solid evidence concerning management of these patients. We congratulate the authors for the excellent work and would like to solicit authors’ expert opinion about some points.

边界可切除的胰腺癌：一个不断发展的概念

我们感兴趣地阅读了Gilbert等人于2017年4月发表在《肿瘤学年鉴》（Annals of Oncology）上的题为《边界可切除胰腺癌：概念演变和当前基于图像的分类方法》的文章。[1]。这篇综述广泛讨论了关于可切除的交界性胰腺癌（BRPC）的主要争议：缺乏普遍认可的定义，各个机构之间的实践存在差异，以及缺乏有关这些患者管理的确凿证据。我们祝贺作者的出色工作，并希望就某些观点征求作者的专业意见。
