NIACE score for hepatocellular carcinoma patients treated by surgery or transarterial chemoembolization.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) prognostic scores could be useful in addition to the Barcelona Clinic Liver Cancer (BCLC) system to clarify patient prognosis and guide treatment decision. The NIACE (tumor Nodularity, Infiltrative nature of the tumor, serum Alpha-fetoprotein level, Child-Pugh stage, ECOG performance status) score distinguishes different prognosis groups among BCLC A, B, and C HCC patients. Our aims are to evaluate the NIACE score and its additive value in two HCC cohorts treated either by surgery or by chemoembolization, and then according to the BCLC recommendations. PATIENTS AND METHODS: This was a retrospective multicenter study with two BCLC A, B, and C HCC cohorts treated either by surgery (n=207) or by chemoembolization (n=168) carried out between 2008 and 2013. We studied survival time according to the baseline NIACE score and compared it with the Cancer of the Liver Italian Program score and the BCLC system. RESULTS: The NIACE score differentiates between subgroups of patients with different prognosis within each BCLC class. Among BCLC A patients treated by surgery and BCLC B patients treated by chemoembolization, the NIACE score differentiates between two subgroups with a significant difference in survival time: 68 (55-81) months versus 35 (21-56) months (P=0.0004) and 20 (17-24) months versus 13 (7-17) months (P=0.0008), respectively. Among those subgroups, the NIACE score has a significantly better prognostic value than the BCLC system or the Cancer of the Liver Italian Program score. CONCLUSION: In this study, among HCC patients treated according to the BCLC recommendations, the NIACE score predicts more accurately than any other system the survival time.

Contrast-enhanced ultrasonography in patients with glycogen storage disease type Ia and adenomas.

OBJECTIVE: The purpose of this series was to evaluate the value of contrast-enhanced ultrasonography (CEUS) in the characterization of focal liver lesions (FLLs) in patients with glycogen storage diseases (GSDs). METHODS: Contrast-enhanced ultrasonographic data obtained for characterization of 8 FLLs (size, 0.9-10.2 cm) in 2 patients with GSD type Ia (GSD-Ia) and lesion growth or recurrent abdominal pain were reviewed and compared with computed tomographic (CT) and magnetic resonance imaging (MRI) data. After total and left hepatectomy, pathologic examination confirmed benign adenomas in 6 of the evaluated lesions. Follow-up confirmed benignity in the 2 remaining lesions. RESULTS: In all FLLs, CEUS showed marked hypervascularity in the early arterial phase. Centripetal filling was shown in only 1 lesion, and diffuse enhancement without any clear direction was shown in all other lesions. During the portal and late phases, 6 of the 8 lesions showed sustained enhancement, including 2 lesions that appeared heterogeneous during all phases of CT and MRI. In an aspect of 1 of these 6 large adenomas, late wash-out could be explained by sinusoid compression. The other 2 adenomas showed moderate wash-out but remained homogeneous. CONCLUSIONS: Focal liver lesions found in patients with GSD-Ia have similar patterns on CEUS compared with incidental adenomas. Global or partial hypoenhancement observed in the late phase did not indicate a transition to hepatocellular carcinoma but may have been related to ischemia.
