Changes in liver function parameters after percutaneous radiofrequency ablation therapy in patients with hepatocellular carcinoma.

Aim: To evaluate changes in liver function parameters and risk factors 1 year after percutaneous radiofrequency ablation (RFA) therapy in patients with hepatocellular carcinoma (HCC).

Methods: Subjects in this retrospective study comprised 45 patients with HCC who underwent RFA therapy (RFA alone, n = 25; transcatheter arterial embolization therapy before RFA, n = 20) and showed no recurrence of HCC 1 year after RFA. Serial changes in serum total bilirubin, albumin, prothrombin time and Child-Pugh score (CPs) were evaluated before and after RFA.

Plasma and urine levels of urinary trypsin inhibitor in patients with chronic liver diseases and hepatocellular carcinoma.

Background And Aim: Because urinary trypsin inhibitor (UTI) is synthesized by hepatocytes and excreted into the urine, plasma and urine levels of UTI may alter in liver diseases. However, there are few reports on the changes in these levels in chronic liver diseases and hepatocellular carcinoma (HCC). The aim of the present study was to evaluate the relationships between plasma and urine UTI levels and the severity of liver damage or progression of HCC in patients with chronic liver diseases and HCC.

Contrast-enhanced ultrasonography using levovist: Usefulness of diagnosis of small focal nodular hyperplasia lesions.

Differential diagnosis of focal nodular hyperplasia and hepatocellular carcinoma is clinically important because, while both are hypervascular tumors, they have vastly different prognoses. Because the spoke-wheel appearance is the primary characteristic of focal nodular hyperplasia, we attempted to detect this pattern in nodules smaller than 3 cm in diameter with contrast-enhanced ultrasonography using a contrast agent (Levovist). Four patients were examined with contrast-enhanced US: two of the patients were examined with Coded Harmonic Angio; the other two patients were examined with contrast-enhanced color and power Doppler US without harmonic imaging.

Primary carcinoid tumor of the liver: A case report.

A53-year-old woman was hospitalized with a hepatic tumor that had been detected on health-screening ultrasonography. Laboratory data showed no marked findings: HBs-Ag and HCV-Ab were negative, and levels of serum AFP, PIVKA-II, CEA, and CA 19-0 were within their normal ranges. Ultrasonogram showed a hyperechoic circle concentric with and inside of a hypoechoic mass in the right hepatic lobe.
