& Aims: Hepatocellular (HCC) surveillance guidelines for patients with chronic hepatitis B virus (HBV) infection are based on race- and age-specific estimates of HCC risk, derived from studies conducted in areas in which HBV is endemic.
We conducted a retrospective cohort study using the national Veterans Administration data to identify patients with chronic HBV infection from 2001 through 2013. We examined the effect of race and age on HCC risk while adjusting for baseline clinical characteristics.
The study cohort had 8329 patients; 3498 patients (42.0%) were white, 3248 (39%) were African Americans (AAs), and 659 (7.9%) were Asian Pacific Islanders (APIs). The annual HCC incidence was highest in APIs (0.65%), followed by whites (0.57%) and AAs (0.40%). After adjusting for clinical and viral factors, the risk of HCC was significantly higher in APIs compared with whites (adjusted hazard ratio [HR]=2.04; 95% CI, 1.31-3.17). There was no difference in HCC risk between AAs and whites (adjusted HR, 0.77; 95% CI, 0.58-1.02). HCC risk increased with age: adjusted HR=1.97 (95% CI, 0.99-3.87) for 40-49 years; adjusted HR= 3.00 (95% CI, 1.55-5.81) for 50-59 years; and adjusted HR=4.02 (95% CI, 2.03-7.94) for more than 60 years vs less than 40 years. Patients with cirrhosis had higher risk of HCC than patients without cirrhosis (adjusted HR=3.69; 95% CI, 2.82-4.83). However, even among patients without cirrhosis, the annual incidence of HCC was more than 0.2% for all patients older than 40 years with high levels of alanine aminotransferase-regardless of race.
In a sample of male veterans with chronic HBV infection, risk of HCC is highest among APIs, followed by whites and AAs. Cirrhosis increased HCC risk. Among patients without cirrhosis, male patients who are older than 40 years and have increased levels of alanine aminotransferase might benefit from HCC surveillance, regardless of race.
