For many, a radiation technique called stereotactic body radiotherapy presents a less invasive treatment option to surgery that is typically offered to non-surgical candidates. Currently there is great interest in evaluating this approach in surgical candidates, but researchers have yet to identify an early method to determine the effectiveness in treatment which is vital.
In a study presented today at the American Society for Therapeutic Radiology and Oncology’s 49th Annual Meeting in Los Angeles, researchers present data showing metabolic response monitored by FDG PET may be an early surrogate for local treatment failure which may allow timely salvage surgery if deemed necessary.
“Stereotactic body radiotherapy may be as effective a treatment of these small tumors as compared to surgery,” explained Steven Feigenberg, M.D., an attending physician in the Department of Radiation Oncology at Fox Chase Cancer Center. “Because the technique causes scaring in the lungs, it can be difficult to identify progression of the tumor on a CT scan in a timely fashion, our standard way of tracking lung tumors, which may adversely affect outcomes due to potential treatment delays.”
“Our study appears to show PET scans at 3 months following treatment allow an earlier and more accurate method to evaluate tumor response. Confirming these findings is critical so that we can scientifically compare stereotactic body radiotherapy with surgery for these small tumors.”

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
