Abstract
BACKGROUND
To determine the predictive value of serum abnormal prothrombin (PIVKA-II) and alpha-fetoprotein (AFP) for the non-objective response of HBV-associated hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE).
METHODS
This prospective study included HBV-associated HCC patients who underwent TACE at the Fourth People's Hospital of Qinghai Province between December 2021 and July 2022. According to contrast-enhanced ultrasound and upper abdomen contrast-enhanced MRI, the patients were divided into the objective response group and the non-objective response group 3 months after TACE.
RESULTS
There were 54 patients, of whom 31 experienced non-objective responses. The PIVKA-II levels in the objective response group were significantly lower than in the non-objective response group at 1 month [352.00 (142.16-722.54) vs. 528.58(241.32-1681.23) mAU/ml, P = 0.005] and 3 months [28.96 (20.01-42.49) vs. 2082.55 (52.63-10 057.30) mAU/ml, P = 0.016] after TACE. The Spearman rank correlation analysis showed no significant correlation between PIVKA-II and AFP (r = 0.315, P > 0.05). The areas under the curve (AUCs) of AFP and PIVKA-II before TACE were 0.632 and 0.529. One month after TACE, the AUC of PIVKA-II combined with AFP (AUC = 0.787) was higher than for PIVKA-II (AUC = 0.658) and AFP (AUC = 0.749).
CONCLUSION
PIVKA-II does not outperform AFP in predicting non-objective response after TACE in HCC patients. The combination of PIVKA-II and AFP might improve the diagnosis of HCC non-objective response after TACE.
