Researchers present findings on treatments for prostate and breast cancer


Five studies detailed at Annual Scientific Sessions of the American Society for Therapeutic Radiology and Oncology (ASTRO)

Researchers from the Department of Radiation Oncology and the Milton and Caroll Petrie Department of Urology at Mount Sinai School of Medicine are presenting findings from five studies of prostate and breast cancer treatments at the 46th Annual Scientific Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO), October 3-7, 2004, in Atlanta, Georgia.

The research being detailed:

  • In a finding with important implications for the design of future clinical trials for prostate cancer treatments, results from a study led by Richard G. Stock, MD, Professor Chairman of Radiation Oncology indicate that using death rates from prostate cancer as an endpoint in clinical trials will fail to differentiate differences in local treatment approaches within ten years. The study found that factors affecting the local control of prostate cancer following brachytherapy have little impact on the death rate from the disease within the first ten years following therapy. (Presentation title: "Does local control impact prostate cancer specific survival within the first 10 years following brachytherapy?")
  • A study led by Barry Rosenstein, PhD, Director of Radiation Biology Program and Professor of Radiation Oncology found a specific genetic alteration linked to related side effects in women treated for breast cancer with radiotherapy. The discovery of this genetic alteration may prove useful in identify genetic predictors associated with adverse radiotherapy response and point to the possibility of creating radiotherapy regimens specifically tailored for individual breast cancer patients. (Presentation title: "ATM sequence variants and adverse radiotherapy response in breast cancer patients")
  • A study led by Jamie Cesaretti, MD, Assistant Professor of Radiation Oncology establishes a significant correlation between common genetic alterations and the development of erectile dysfunction, proctitis and urinary bother following radiotherapy for prostate cancer. (Presentation title: "ATM sequence variants are predictive of adverse radiotherapy response among patients treated for prostate cancer")

In poster presentations:

  • Nelson N. Stone, MD, Clinical Professor of Urologic Oncology, and David T. Marshall, MD, Assistant Professor of Radiation Oncology, confirm the importance of prostate biopsy results following brachytherapy and explore the effects of hormonal therapy given prior to brachytherapy on the severity of urinary side effects following radiation treatment.
  • Dr. Armen Kassabian, M.D., and Natan Bar-Chama, M.D. will be presenting their findings on the development of erectile dysfunction following prostate brachytherapy which negatively affected by additional use of hormonal therapy.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'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...
