High prevalence of hepatic focal nodular hyperplasia in subjects with hereditary hemorrhagic telangiectasia.

A vascular pathogenesis of hepatic focal nodular hyperplasia (FNH) has been suggested; this study was aimed to evaluate in families with hereditary hemorrhagic telangiectasia (HHT) the prevalence of FNH, relating it to presence and stage of hepatic vascular malformations (VMs). Fifty-two HHT families underwent a screening program including abdominal Doppler sonography (US) searching for hepatic VMs; we classified them as minimal, moderate and severe, depending on the number and degree of abnormalities found by Doppler US. Presence of focal liver lesions was recorded. Diagnosis of FNH was made if at least two examinations, whether color Doppler US, liver scintigraphy, dynamic computed tomography (CT) or magnetic resonance (MR), showed suggestive findings. FNH was found in five out of 274 subjects (1.8%). All five were affected by HHT. Thus, percentage related to the group of affected patients increased to 2.9; 4/5 presented severe liver VMs. Female-to-male ratio was 4:1. FNH was single in three cases; tumor size ranged between 20 and 90 mm. During follow-up, no lesion showed a reduction in size, three showed an increase. Prevalence of FNH in patients with HHT is far greater than that reported in the general population; Doppler US role in its diagnosis and follow-up is highlighted.

Increased survival of cirrhotic patients with a hepatocellular carcinoma detected during surveillance.

BACKGROUND & AIMS: Significant improvements in management of hepatocellular carcinoma (HCC) have occurred in the last years, but their impact on surveillance outcome is unknown. To clarify this, we compared survival of HCC patients identified along 3 consecutive quinquennia of surveillance. METHODS: A cohort of 417 HCC-free outpatients with compensated cirrhosis was prospectively followed for 148 months (range, 1-213 months) with periodic ultrasound examinations. RESULTS: HCC developed in 112 patients, at a 3.4% rate per year, and was the prime cause of death (n = 54). Forty-six (41%) patients had a single tumor, with a mean size of 3.7 cm, 3.0 cm, and 2.2 cm in the 3 quinquennia (first vs. second: ns; first vs. third: P = 0.017; second vs. third: P = 0.02), and 38 (44%) underwent radical therapy. Mortality rates in HCC patients fell from 45% in the first quinquennium to 37% in the second and 10% in the third (first vs. second: ns; first vs. third: P = 0.0009; second vs. third: P = 0.018) in parallel with a reduction in yearly mortality of treated patients (34%, 28%, and 5%, respectively; first vs. second: ns; second vs. third: P = 0.036; first vs. third: P = 0.0024). After stratification for quinquennium, tumor staging, according to Cancer of the Liver Italian Program (CLIP), was the only independent predictor of survival (P = 0.015). CONCLUSIONS: Cirrhotic patients developing a HCC during the last 5 years of surveillance survived longer than previously, as a consequence of improved management of the tumor and complications of cirrhosis.

Segmental transcatheter arterial chemoembolization treatment in patients with cirrhosis and inoperable hepatocellular carcinomas.

PURPOSE: To establish whether segmental transcatheter arterial chemoembolization (TACE) treatment may improve the rates of survival in patients with compensated cirrhosis and inoperable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Fifty-six patients with compensated cirrhosis and inoperable HCC were treated with segmental TACE. One hundred forty treatments (mean, 2.5 per patient; 30-60 mg Epirubicin, 4-10 mL Lipiodol, and Gelfoam particles) were administered. RESULTS: During the 69-month study, 25 patients (45%) died of tumor progression, 12 (21%) of liver failure, nine (16%) of gastrointestinal hemorrhage, and three (5%) of other causes; seven patients (13%) are still alive. The 3-year rate of survival was 32%. Intention-to-treat analysis determined that patients with Child-Pugh class A disease (n = 44; 79%) or a single <5-cm HCC (n = 21; 37%) had a higher rate of survival than those with Child-Pugh class B disease (n = 12; 21%; P <.002) or a larger HCC (n = 35; 63%; P <.02) and patients (n = 41) who were treated with more than one course of TACE had a higher rate of survival than those who were treated with a single TACE procedure (n = 15; P <.0003). Multivariate analysis was used to predict rates of survival by number of treatments (hazard ratio, 0.6; CI, 0.48-0.86; P <.004), Child-Pugh class (hazard ratio, 2.8; CI, 1.41-5.74; P <.003), and tumor size (hazard ratio, 3.8; CI, 1.81-8.01; P <.001). The 3-year rate of survival in patients with Child-Pugh class A disease and a < or =5-cm-HCC (n = 16) was 56%. This result was similar to the 50% 3-year rate of survival in untreated historic controls with similar characteristics. CONCLUSION: The rate of survival in patients with compensated cirrhosis and inoperable HCC did not appear to improve with use of TACE therapy.
