Level of Hepatitis B Core-Related Antigen and Risk for Hepatocellular Carcinoma

Virginia A. Schad, PharmD, RPh
A high level of hepatitis B core-related antigen (HBcrAg) is a complementary risk factor for hepatocellular carcinoma (HCC) development, according to a study published in Gastroenterology.

One of the main causes of death in patients with hepatitis B virus (HBV) infection is HCC; therefore, identifying patients at high risk for HCC is important for providing preemptive antiviral treatment to reduce risk. Serum levels of HBcrAg are associated with active replication of HBV; therefore, the researchers investigated whether HBcrAg levels associate with development of HCC, especially in patients who do not require antiviral treatment. They collected data from 2666 adults positive for hepatitis B surface antigen (HBsAg), infected with HBV genotypes B or C and without liver cirrhosis, who had long-term follow-up at the National Taiwan University Hospital from 1985 through 2000 and did not have antiviral treatment during the follow-up.

They found that in the entire cohort, 209 patients developed HCC (incidence rate, 4.91 cases/1000 person-years), and there was a positive association between baseline of HBcrAg and HCC development. Among patients with an intermediate viral load from 2000 to 19,999 IU/mL, those with a high HBcrAg level (≥10 KU/mL) had an HCC risk close to those with a high viral load (≥20,000 IU/mL), whereas those with a low HBcrAg level had an HCC risk similar to that of minimal risk carriers.

“In summary, in a cohort of 2666 patients infected with HBV genotypes B or C, baseline HBcrAg level serves an independent risk factor for HCC development,” stated the authors. “Therefore, HBcrAg of 10 KU/mL may serve a novel biomarker for the management of patients with [intermediate viral load] in our clinical practice,” they concluded.

乙肝核心相关抗原水平和肝细胞癌风险

弗吉尼亚·夏德(Virginia A.
根据胃肠病学发表的一项研究,高水平的乙型肝炎核心相关抗原(HBcrAg)是肝细胞癌(HCC)发展的补充危险因素。

乙肝病毒感染是导致死亡的主要原因之一。因此,识别高危肝癌患者对于提供先发性抗病毒治疗以降低风险很重要。血清HBcrAg水平与HBV主动复制有关。因此,研究人员调查了HBcrAg水平是否与HCC的发展有关,特别是在不需要抗病毒治疗的患者中。他们收集了2666名乙型肝炎表面抗原(HBsAg)阳性,感染了B型或C型HBV且无肝硬化的成年人的数据,这些人从1985年至2000年在国立台湾大学医院进行了长期随访,并且没有随访期间进行抗病毒治疗。

他们发现,在整个队列中,有209例患者发生了HCC(发生率,4.91例/ 1000人年),并且HBcrAg基线与HCC的发生呈正相关。在2000至19,999 IU / mL的中等病毒载量患者中,HBcrAg水平高(≥10KU / mL)的患者的HCC风险接近高病毒载量(≥20,000IU / mL)的患者,而那些HBcrAg水平低的人的HCC风险与最低风险携带者的相似。

这组作者说:“总的来说,在2666名感染了HBV基因型B或C的患者中,基线HBcrAg水平是肝癌发展的独立危险因素。”他们总结说:“因此,在我们的临床实践中,10 KU / mL的HBcrAg可能成为治疗[中度病毒载量]患者的一种新型生物标志物。”
