Study results presented at the 39th annual meeting for the American Society of Clinical Oncology (ASCO) by Chandra P. Belani, M.D., professor of medicine, University of Pittsburgh and co-director, Lung Cancer Program, University of Pittsburgh Cancer Institute (UPCI), demonstrate that a new therapeutic radiation strategy for non-small cell lung cancer (NSCLC) – the most common form of the disease – leads to improved survival for lung cancer patients with locally advanced disease.
n the study, hyperfractionated accelerated radiotherapy (HART) was compared to standard thoracic radiotherapy following chemotherapy. HART is a strategy in which radiation is administered frequently over a shorter period of time for two and a half weeks compared to seven weeks.
The phase III multi-site study compared HART to standard radiation therapy in 119 patients with unresectable stage III NSCLC. The patients were randomized into the two groups following two cycles of chemotherapy. Results indicated a median survival of 21 months for patients who received chemotherapy followed by HART, compared to a median survival of 12 months for patients who received chemotherapy followed by standard radiation therapy. One, two and three-year survival rates were 60 percent, 37 percent and 23 percent respectively in the HART group compared to one, two and three-year survival rates of 52 percent, 28 percent and 15 percent in the standard radiation therapy group.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
