Survival Outcomes Suggest Consideration of Additional Lymph Node Dissection for Incidentally Diagnosed Intrahepatic Cholangiocarcinoma Patients

Survival outcomes of incidental intrahepatic cholangiocarcinoma patients who did not undergo lymph node dissection were similar to those who underwent dissection in T1 stage, but poorer in T2 and T3+4 stages. Patients incidentally diagnosed with T2 or above T stage may benefit from additional lymph node dissection based on the study’s retrospective analysis of 284 patients who had undergone radical surgery for intrahepatic cholangiocarcinoma.
