肝内胆管细胞癌(ICC)是肝脏第2常见的原发性恶性肿瘤且预后非常差。为了更好地指导临床治疗,美国癌症联合会(AJCC)在第7版《AJCC肿瘤分期手册》中首次将ICC与肝细胞癌分开,单独设置章节,反映了ICC的危险因素与肝细胞癌的差异性。而最近出版的第8版《AJCC肿瘤分期手册》中进一步对ICC的TNM分期系统进行了更新。其中,不再以肿瘤大体分型特征进行T分期,同时淋巴结转移(N1期)被归入ⅢB期,而非第7版中归入Ⅳ期。另外还对区域淋巴结和远处转移等做出了明确定义,并推荐至少清扫6枚区域淋巴结方可进行准确的N分期。第8版AJCC肝内胆管细胞癌分期系统的优势在于能够更准确地显示患者预后,对临床具有更高的指导价值。
Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer with a very poor prognosis. In order to guide better clinical management of ICC patients, the American Joint Committee on Cancer (AJCC) cancer staging manual (7th edition) have established a unique TNM staging scheme for separating ICC from hepatocellular carcinoma (HCC) for the first time, and reflected a difference between risk factor of ICC and HCC. This TNM staging system for ICC has been most recently updated by the AJCC cancer staging manual (8th edition), in which T staging has been redefined without gross features, and lymph node metastasis (N1) in N staging has been grouped as stage ⅢB, but not stage Ⅳ as required by the 7th edition of AJCC cancer staging manual. In addition, region lymphatic and distant metastases have been clearly redefined by the AJCC cancer staging manual (8th edition) that also requires recovering at least 6 lymph nodes for the N staging scheme. The apparent advantages of the AJCC cancer staging manual (8th edition) for ICC pathologic staging may better stratify the prognosis of ICC patients and provide an improved guidance in clinical practice.
