In the first national study to examine survival among liver transplant patients with advanced hepatocellular carcinoma (HCC), researchers found excellent five-year survival results, with a steady improvement over the last decade. Hepatocellular carcinoma, also known as hepatoma, or cancer of the liver, is a common cancer worldwide, with more than one million new cases diagnosed each year and a median life expectancy of six to nine months. Most hepatoma patients have cirrhosis, a risk factor of hepatoma, and are inoperable because of tumor size, location or severity of underlying liver disease. Results of this study will be reported online in the Journal of Clinical Oncology.
"This study shows that we can achieve excellent survival with liver transplantation among patients with hepatoma, confirming similar results reported by single center studies," said Paul J. Thuluvath, MD, senior author and Associate Professor in the Department of Medicine at Johns Hopkins University School of Medicine. "These findings are particularly reassuring for patients with tumors that cannot be surgically removed, which comprise more than 80 % of HCC patients."
The primary objective of the study was to determine survival in an unselected patient population who had liver transplantation for HCC. Using the United Network for Organ Sharing (UNOS) database, researchers collected data on 48,887 patients who underwent liver transplantation in the United States between 1987 and 2001. Patients were excluded if they had undergone multiple organ transplantation, retransplantation, were less than 18 years of age, or lacked survival information.

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
