改良胰腺神经内分泌肿瘤分期的临床解读

胰腺神经内分泌肿瘤是一种常见的胰腺恶性肿瘤,异质性极强,诊治手段多样,因此,统一、实用的分期系统将有助于临床诊治及研究.目前,胰腺神经内分泌肿瘤包括欧洲神经内分泌肿瘤协会(European Neuroendocrine Tumor Society System,ENETS)和美国癌症联合委员会(American Joint Committee on Cancer,AJCC)两种分期,然而两种分期系统对临床指导价值有限,且两种分期系统的并存造成了分期系统混乱的局面.复旦大学附属肿瘤医院胰腺肝胆外科通过结合ENETS中TNM的定义及AJCC中分期的定义,建立了改良的分期系统,该分期能更好地区分出不同预后的人群,更适合于指导临床应用,有利于建立统一的临床分期标准.研究结果发表在《临床肿瘤学杂志》(Journal of Clinical Oncology,JCO)上.研究得到了国际同行的高度重视与认可,被评为"2017 Best of JCO:Gastrointestinal edition".JCO编辑部进行了专篇述评.该研究就改良分期系统的临床应用进行解读.

The clinical interpretation of modified staging system for pancreatic neuroendocrine tumors

Pancreatic neuroendocrine tumor is a common pancreatic tumor with high heterogeneity and multiple management modalities. A standard and practical staging system for pancreatic neuroendocrine tumors will be beneficial to clinical management and research. At present, there are two staging systems (ENETS and AJCC). Both of them have shortcomings which limit their clinical application. In addition, the coexistence of two staging systems is confusing to clinicians. We proposed a modified ENETS staging system by keeping the ENETS TNM definition and adopting the AJCC staging definition. The modified staging system can successfully distinguish patients with different prognosis and is helpful in establishing clinical standard. This study has been published in Journal of Clinical Oncology (JCO) and was selected as "2017 Best of JCO: Gastrointestinal edition". This paper was aimed to interpret the modified staging system in clinical practice.
