Two studies in the February 1 issue of the Journal of the National Cancer Institute examine whether hospital volume, surgeon experience, or surgeon specialty affect the treatment received and the risk of death following treatment among women with ovarian cancer.
Past studies have suggested that patients treated at hospitals with higher case loads or by more experienced surgeons have higher survival rates after surgery for certain types of cancer, including colorectal cancer and lung cancer. Patients may take such factors into account when making decisions about where and from whom to seek medical care.
Ovarian cancer ranks fourth in cancer death in U.S. women and was expected to have claimed more than 16,000 lives in 2004. It is typically a disease of women in their sixth or seventh decade. To examine the association between hospital case volume and procedure-specific experience of surgeons on outcomes after ovarian cancer surgery, Deborah Schrag, M.D., of the Memorial-Sloan Kettering Cancer Center in New York City, and colleagues used the Surveillance, Epidemiology, and End Results (SEER)–Medicare linked database to identify 2952 patients age 65 or older who had surgery for primary ovarian cancer between 1992 and 1999. They looked at both short-term (60-day) and longer term (2-year) mortality rates and overall survival.

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...
