Chronic hepatitis B (CHB) infection is an important health issue worldwide. Novel antiviral treatments lead to complete suppression of the virus and maintained suppression of viral replication prevents cirrhosis, decompensation in already cirrhotic patients and hepatocellular carcinoma (HCC). However, HCC risk is not totally eliminated and in pursuance of detecting cancer in early stages comprehensive follow up is needed. It is critical to stratify patients for risk predictions, especially to prevent unnecessary tests in low-risk patients.
Various risk scores have been developed to predict the development of HCC in CHB patients. The majority of studies on the risk scores had focused on untreated patients. Currently, almost all patients with CHB are treated with antiviral agents and better risk scores for patients under treatment is needed. The PAGE-B is a risk scoring system that includes platelet count, age and sex and has been validated in patients treated with antivirals.
We aimed to evaluate the accuracy of the PAGE-B scoring system in the prediction of HCC risk in CHB patients receiving entecavir (ETV) or tenofovir disoproxil fumarat therapy.
We recruited 742 CHB patients who had been treated with tenofovir disoproxil fumarate or ETV for more than 1 year. Risk groups were determined according to the PAGE-B scores. We evaluated the accuracy of the PAGE-B score in predicting HCC.
HCC was diagnosed in 26 patients (3.5%) during 54.7 ± 1.2 mo mean follow up. The cumulative HCC incidences at 5 years were 0% in the PAGE-B low-risk group; 1.5% moderate-risk group; and 12.5%, in the high-risk group (log-rank p < 0.001). The AUROCs of the PAGE-B score in the prediction of HCC development at 5 years follow up was 0.903.
PAGE–B had successfully predicted the patients who had a low risk of HCC during treatment with genetically high barrier antivirals.
PAGE-B is a simple score that does not require biopsy or any impractical molecular test. The efficiency of PAGE-B justifies implementing this score in daily clinical practice.
