A new study says cancer surgery performed at a medical center designated by the National Cancer Institute (NCI) as a "center of excellence" is associated with less risk of death soon after surgery than if performed at a high-volume surgery center, but finds no difference in five-year survival rates. The full study will be published in the February 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society. This study was supported by grants from the NCI and the Agency for Healthcare Research and Quality (AHRQ).
In 1971 the NCI created a program to award cancer centers special designation as centers of regional excellence if they demonstrated excellence in three areas: research, cancer prevention, and clinical services. NCI cancer centers are well staffed with specialists, tend to have high procedure volumes, and better access to multidisciplinary consultation and the latest therapies--all reasons to believe they would have better outcomes than other cancer centers. Although these centers often advertise their superior outcomes, say the studys authors, to date their relative performance has not been examined.
Nancy J. O. Birkmeyer, Ph.D. from the Department of Surgery at the University of Michigan Medical School and her colleagues investigated whether this designation actually improves survival. The investigators reviewed data from 63,860 cancer patients who underwent cancer surgery. Patients treated at one of the 51 NCI cancer centers were compared to those from 51 control cancer centers with the highest volumes for each procedure.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
