Intrahepatic cholangiocarcinoma is an aggressive, often fatal, malignancy that arises from the bile ducts. As it often presents with metastatic disease, surgery has limited utility. However, in some cases, neoadjuvant chemotherapy has provided the necessary reduction in tumor burden to allow for adequate resection. Consequently, new advances in neoadjuvant chemoradiation and targeted therapy are of interest with numerous case reports and small series published routinely; it is challenging to present a large case series or study given the overall rare frequency with which this malignancy is seen. Herein, we aim to summarize the newest advances in both neoadjuvant chemotherapy and targeted immunotherapy.
