摘要
Intrahepatic cholangiocarcinoma(iCCA)is the second most common type of liver cancer after hepatocellular carcinoma,accounting for 15%of all primary liver neoplasms.In particular,iCCA is the most lethal tumor of these types,with the greatest increase in incidence in Western countries over the last decade(1,2).Local resection is the only treatment that can achieve cure,but resection rates remain low and survival is still limited to less than 1 year in the presence of locally unresectable or distant metastases(3).Its incidence and mortality have increased in recent years,and the total number of new cases is expected to increase up to 10-fold over the next two to three decades.In recent years,new treatments for iCCA have been developed and overall survival has improved.
