The first study to compare survival between women with breast cancer whose treatment was based on consensus guidelines and those whose treatment was not shows that adhering to established guidelines improves survival and reduces the risk of recurrence. The study retrospectively examined whether the systemic therapy prescribed after surgery for women with early-stage breast cancer was consistent with treatment guidelines established for at the time. Systemic therapy includes chemotherapy and hormonal therapy and is designed to reach cancer cells that may have spread beyond the original tumor site. The study and an accompanying editorial will be published online August 2 in the Journal of Clinical Oncology (JCO) at http://www.jco.org.
Using medical records from Canada’s national health care system, Dr. Hébert-Croteau and her colleagues compared survival between 1,002 women with early breast cancer whose systemic treatment was delivered according to guidelines developed at the 1992 St-Gallen conference in Switzerland, and 380 women whose treatment differed from those guidelines. The study also included 159 women whose guideline adherence was unknown. The women were diagnosed between 1988 and 1994 with invasive breast cancer that had not spread to nearby lymph nodes.
Developed by consensus with input from oncologists in Europe and North America, the St-Gallen guidelines continue to be updated regularly and are considered among the best guidelines available. The guidelines stipulate whether a woman with node-negative breast cancer should, after surgery, receive tamoxifen, chemotherapy, neither (as is the case for women at low risk of recurrence), or both, depending on her risk.

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.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
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.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
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...
