Clinical Trial Summary
In Asia, hepatocellular carcinoma (HCC) commonly occurred in the underlying hepatitis B virus
(HBV)-related liver disease.Curative therapies could improve the prognosis of HCC patients.
However, tumor recurrence after curative therapy remains high with a 5-year recurrence rate
>70%.The risk for HCC development is increased for patient with HBV infection,but there was
no consensus about which kind of oral antiviral treatment was the best option in the
prevention of HBV related HCC recurrence after curative treatment.Therefore, we conducted
this study to investigate the different effects of nucleotides(TDF) and nucleosides(ETV) on
the prognosis of HBV-related HCC after curative resection.
Description:
The study was designed to compare the efficacy of ETV and TDF for patients with HBV-related
HCC patients undergoing curative liver resection. Eligible patients were randomly assigned in
a 1:1 ratio via computer-generated allocation to either the ETV group or TDF group. A block
size and strata were used in the randomization. In 2015, the American Association for the
Study of Liver (AASLD) adopted ETV and TDF as first-line antiviral treatments for chronic
hepatitis B. Patients in the ETV group received ETV tablets (RunZhong, CHIATAI TIANQING,
China) 0.5 mg/d orally starting from 2-4 weeks before surgery; those in the TDF group receive
TDF tablets(Viread, Aspen Port Elizabeth, China) 300 mg/d orally starting from 2-4 weeks
before surgery. Antiviral treatment was continued unless there was unacceptable toxicity or
withdrawal of consent.
Preoperatively, all patients underwent chest radiography and at least 2 dynamic imaging
examinations (contrast-enhanced ultrasound, contrast-enhanced computed tomography(CT) or
magnetic resonance imaging(MRI)). HBsAg and hepatitis B e antigen (HBeAg), HBV-DNA load,
anti-HCV, alpha-fetoprotein (AFP), carcinoembryonic antigen(CEA), carbohydrate antigen
19-9(CA19-9), liver function and HBV genotypes were serologically examined within 1 week
before surgery. Additional serum samples were collected to test single-nucleotide
polymorphisms(SNPs) of the interleukin 28B(IL-28B) gene and serum levels of
interferon(IFN)-λ1, IFN-λ2, IFN-λ3, IL-1β, tumor necrosis factor alpha(TNF-α), IL-6, IL-8 and
IL-10. All serum and DNA samples were stored at -80°C until use.
After general anesthesia, surgery was performed as the standard protocol. Intraoperative
ultrasonography was performed to assess the relationship of the tumor to vascular structures
and to eliminate the extrahepatic metastasis. Pringle's maneuver was applied to occlude the
blood inflow of the liver with cycles of 15 minutes clamp time and 5 minutes unclamped time.
Liver resection was carried out by the Cusa Excel Ultrasonic Surgical Aspirator System(CUSA).
In the study, the primary outcome measures included both recurrence and overall survival
rates from the date of the operation. Secondary outcome measures included patient tolerance
of antiviral treatment, virologic response, liver function and additional cytokines such as
IFN-λ1 IFN-λ2, IFN-λ3, IL-1β, TNF-α, IL-6, IL-8 and IL-10. All the patients received
follow-up monitoring 1 month after the operation, every 3 months thereafter during the first
3 years, and then every 6 months in subsequent years. Physical examination, blood cell and
differential counts, renal and liver function tests, AFP levels, HBV serology and HBV-DNA
levels, serum IFN-λ level and imaging examinations were included in the follow-up
examinations when necessary. Follow-up was continued until August 2020 when all surviving
patients had a minimum follow-up of 24 months.
Tumor recurrence was diagnosed based on the identification of a new lesion on at least 2
radiological examinations and increased AFP levels (>100 ng/mL). Patients with tumor
recurrence were actively treated with salvage liver transplantation, repeat hepatic
resection, radiofrequency ablation, transcatheter arterial chemoembolization(TACE),
sorafenib, and/or chemotherapy, depending on the extent of the disease, the liver function,
and general condition of the patient.
