胆道肿瘤是危害人类健康的胆道疾病。由于其恶性程度高,且起病隐匿,早期诊断率很低,确诊时往往已到中晚期,失去了根治性切除的机会,故预后极差。因此,加强胆道肿瘤的生物学特性的研究对于提高胆道肿瘤诊治水平具有重要意义。同其他恶性肿瘤一样,胆道肿瘤也是一种既涉及到外界因 Biliary tumors are biliary diseases that endanger human health. Because of its high degree of malignancy, and the insidious onset, the early diagnosis rate is very low, the diagnosis is often in the advanced stage, lost the chance of radical resection, so the prognosis is extremely poor. Therefore, to enhance the biological characteristics of biliary tumors for improving the diagnosis and treatment of biliary tumors is of great significance. Like other malignancies, biliary tumors are also an external cause
