Nucleos(t)ide analogues to treat hepatitis B virus-related hepatocellular carcinoma after radical resection

Significant advances have been made in nucleos(t)ideanalogue(NA) therapy to treat chronic hepatitis B,and this therapy reduces the risk of hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC) in somepatients.However,whether NAs can also prevent recurrence after radical resection of HBV-related HCC remains controversial and is an important question,giventhat most patients will experience recurrence within afew years of curative surgery.Here we systematicallyreviewed the literature since 2004 on outcomes afteradministering NAs to patients with HBV-related HCCfollowing radical resection.We focused on treatmentindications,duration,effects on recurrence-free survivaland overall survival,and the management of NA resistance.We find that patients with HCC should stronglyconsider NA therapy if they are positive for HBV-DNA,and that the available evidence suggests that postoperative NA therapy can increase both recurrence-free andoverall survival.To minimize drug resistance,cliniciansshould opt for potent analogues with higher resistancebarriers,and they should monitor the patient carefully for emergence of NA-resistant HBV.
