肝门部胆管癌又称近端胆管癌或高位胆管癌,是胆道系统常见的恶性肿瘤,早期诊断困难,手术切除率低,预后差。现代研究表明肿瘤的预后主要取决于肿瘤本身的生物学行为,因此加强对肝门部胆管癌生物学特性的研究是攻关的重要课题。本文现将近年来有关肝门部胆 Hilar cholangiocarcinoma, also known as proximal cholangiocarcinoma or high-grade cholangiocarcinoma, is a common malignant tumor of the biliary system. Early diagnosis is difficult, and the resection rate is low and the prognosis is poor. Modern studies have shown that the prognosis of tumors depends on the biological behavior of the tumor itself. Therefore, it is an important task to strengthen the research on the biological characteristics of hilar cholangiocarcinoma. This article will now cover the gallbladder in recent years
