    Abstract:
    OBJECTIVES: Transcatheter arterial chemoembolization (TACE) is the major treatment modality for patients with unresectable hepatocellular carcinoma (HCC). Hepatic failure after TACE is relatively common in patients with preexisting liver dysfunction. The purpose of this study was to evaluate whether the monoethylglycinexylidide test and other parameters might predict hepatic failure after TACE in HCC patients. METHODS: One hundred forty-two HCC patients undergoing TACE were enrolled into this study. Before TACE, their venous blood was collected 15 min after a bolus injection of lidocaine (1 mg/kg body weight). A fluorescence polarization immunoassay was used to measure monoethylglycinexylidide oncentrations in their sera. Univariate and multivariate analyses were performed on the monoethylglycinexylidide test and other parameters between patients with and without hepatic failure after TACE. RESULTS: Nineteen patients (13.4%) suffered hepatic failure after TACE. Univariate analysis revealed that the monoethylglycinexylidide concentration (17.7+/-5.8 vs 43.9+/-13.2 ng/ml), Child-Pugh score (6.9+/-0.6 vs 6.0+/-0.7), indocyanine green retention ratio at 15 min (32.4+/-6.5% vs 15.7+/-5.8%), prolonged PT, and serum total bilirubin and albumin showed significant differences between patients with and without hepatic failure after TACE. After a multiple logistic regression, only the monoethylglycinexylidide test was an independent predictor of hepatic failure (OR = 1.68, 95% CI = 1.07-2.65, p = 0.026). Among the 19 hepatic failure patients, three (15.8%) died of hepatic failure associated with TACE within 1 month after this procedure. CONCLUSIONS: As a predictor of hepatic failure after TACE, the monoethylglycinexylidide test is better than conventional liver function tests and clinical parameters. The monoethylglycinexylidide test may be used to select patients with relatively good liver reserves for safe TACE treatment.
