AIM To investigate the usefulness of aspartate aminotransferase to platelet ratio index(APRI) in predicting hepatocellular carcinoma(HCC) risk in primary biliary cholangitis(PBC).METHODS We identified PBC patients between 2000 and 2015 by searching the electronic medical database of a tertiary center. The hazard ratio(HR) of HCC with different risk factors was determined by Cox proportional hazards model. RESULTS One hundred and forty-four PBC patients were recru-ited. Patients were diagnosed at a median age of 57.8 years [interquartile range(IQR): 48.7-71.5 years), and 41(28.5%) patients had cirrhosis at baseline. The median follow-up duration was 6.9 years(range: 1.0-26.3 years). Twelve patients developed HCC, with an incidence rate of 10.6 cases per 1000 patient-years. The overall 5-, 10-and 15-year cumulative incidences of HCC were 2.3% 95%CI: 0%-4.8%), 8.4%(95%CI: 1.8%-14.5%) and 21.6%(6.8%-34.1%), respectively. Older age(HR = 1.07), cirrhosis(HR = 4.38) and APRI at 1 year after treatment(APRI-r1) > 0.54(HR = 3.94) were independent factors for HCC development. APRI-r1, when combined with treatment response, further stratified HCC risk(log rank P < 0.05). The area under receiver operating curve of APRI-r1 in predicting HCC was 0.77(95%CI: 0.64-0.88).CONCLUSION APRI-r1 can be used to predict the development of HCC in PBC patients. Combination of APRI-r1 with treatment response can further stratify the HCC risk.

The overall 5-, 10-and 15-year cumulative incidences of HCC were 2.3% 95% CI: 0% -4.8%), 8.4% (95% CI: 1.8% -14.5% % (6.8% -34.1%), respectively. Older age (HR = 1.07), cirrhosis (HR = 4.38) and APRI at 1 year after t APRI-r1, when combined with treatment response, further stratified HCC risk (log rank P <0.05). The area under receiver operating curve of APRI (APRI-r1)> 0.54 -r1 in predicting HCC was 0.77 (95% CI: 0.64-0.88). CONCLUSION APRI-r1 can be used to predict the development of HCC in PBC patients. Combination of APRI-r1 with treatment response can further stratify the HCC risk.
