Adjuvant therapies after curative treatments for hepatocellular carcinoma: Current status and prospects.

ABSTRACT: Tumor recurrence rate after surgery or ablation of hepatocellular carcinoma (HCC) is as high as 70%. However, there are no widely accepted adjuvant therapies; therefore, no treatment has been recommended by guidelines from the American Association for the Study of Liver Disease or the European Association for the Study of the Liver. All the registered trials failed to find any treatment to prolong recurrence-free survival, which is the primary outcome in most studies, including sorafenib. Some investigator-initiated studies revealed that anti-hepatitis B virus agents, interferon-?, transcatheter chemoembolization, chemokine-induced killer cells, and other treatments prolonged patient recurrence-free survival or overall survival after curative therapies. In this review, we summarize the current status of adjuvant treatments for HCC and explain the challenges associated with designing a clinical trial for adjuvant therapy. Promising new treatments being used as adjuvant therapy, especially anti-PD-1 antibodies, are also discussed.
