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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
