Summary of "Risk assessment of hepatocellular carcinoma development by magnetic resonance elastography in chronic hepatitis C patients who achieved sustained virological responses by direct acting antivirals."

Prediction of hepatocellular carcinoma (HCC) development after sustained virological response (SVR) is clinically important and the usefulness of noninvasive markers for prediction HCC have been reported. The aim of this study was to compare the prediction accuracy for HCC development by noninvasive markers. A total of 346 patients with chronic hepatitis C without history of HCC who achieved SVR through direct acting antivirals were included. Magnetic resonance elastography (MRE) and serum fibrosis markers were measured 12 weeks after the end of treatment and the subsequent HCC development was examined. The mean observation period was 26.4 ± 7.9 months, and 24 patients developed HCC. Area under the receiver operating characteristic curve of liver stiffness by MRE, wisteria floribunda agglutinin-positive mac-2 binding protein, and FIB-4 for predicting HCC within 3 years was 0.743, 0.697, and 0.647, respectively. The 1/2/3-year rates of HCC development in patients with liver stiffness ≥3.75 KPa were 6.6%, 11.9%, and 14.5%, whereas they were 1.4%, 2.5%, and 2.5% in patients with liver stiffness <3.75 KPa (p<0.001). Multivariate analysis revealed that liver stiffness ≥3.75 was an independent predictive factor for HCC development (hazard ratio, 3.51; 95% confidence interval, 1.24-9.99). In subgroup analysis, there were 132 patients who were <73 years old and had liver stiffness <3.75 KPa, and no HCC development was observed in these patients. Diagnostic accuracy for predicting HCC development was higher in MRE than serum fibrosis markers and measurement of liver stiffness by MRE could identify patients with high and low risk of HCC development after SVR.

Medical and Biotech [MESH] Definitions

Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.

The first alpha-globulins to appear in mammalian sera during development of the embryo and the dominant serum proteins in early embryonic life. They reappear in the adult serum during certain pathologic states, primarily hepatocellular carcinoma. They may also be elevated in the amniotic fluid and maternal serum during pregnancy in ANENCEPHALY.

A large family of receptor protein-tyrosine kinases that are structurally-related. The name of this family of proteins derives from original protein Eph (now called the EPHA1 RECEPTOR), which was named after the cell line it was first discovered in: Erythropoietin-Producing human Hepatocellular carcinoma cell line. Members of this family have been implicated in regulation of cell-cell interactions involved in nervous system patterning and development.

A non-invasive assessment of the stability of tissue-embedded prosthetic devices such as dental implants.
