Many lung cancer patients get radiation therapy that may not prolong their lives

A new study has found that many older lung cancer patients get treatments that may not help them live longer.

Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings suggest that physicians should not routinely use radiation after surgery to treat lung cancer that is advanced but has not widely spread, at least in older patients.

Patients with locally advanced lung cancer, which has spread to only certain lymph nodes, usually undergo surgery to remove their tumors. Unfortunately, the cancer often comes back, so physicians frequently use radiation therapy to decrease patients' risk of cancer recurrence. To see if this additional treatment actually extends their survival, Juan Wisnivesky, MD, DrPH, of the Mount Sinai School of Medicine in New York City, and his colleagues analyzed information from the Surveillance, Epidemiology and End Results (SEER)-Medicare registry, which links cancer incidence and survival data to a master file of Medicare records. The investigators identified 1,307 cases of locally advanced lung cancer between 1992 and 2005.

In all, 710 patients (54 percent) received radiation following their surgery, but they were not more likely to survive longer than patients who did not receive radiation. "Our results show that we need more information about the potential benefits of radiation therapy before it is used routinely to treat this subset of lung cancer patients," said Dr. Wisnivesky. Such information may come from the Lung Adjuvant Radiotherapy Trial (LungArt), which is an ongoing phase III randomized controlled clinical trial evaluating the effectiveness of radiation following surgery in patients with locally advanced lung cancer.

CANCER is a peer-reviewed publication of the American Cancer Society integrating scientific information from worldwide sources for all oncologic specialties. The objective of CANCER is to provide an interdisciplinary forum for the exchange of information among oncologic disciplines concerned with the etiology and course of human cancer.

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...

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...
