Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast. But new research from the Stanford University School of Medicine suggests that looking at the immune cells in those lymph nodes - instead of the tumor cells - will yield a more accurate forecast. The finding could help clinicians determine which cancers to treat more aggressively to ensure the cancer goes away and doesnt come back.
"Immune changes in the lymph node almost perfectly predict clinical outcome, much better than any other prognostic factor that is available today," said Peter P. Lee, MD, assistant professor of medicine and the senior author of the paper detailing the findings in the Sept. 6 advance online edition of Public Library of Science-Medicine.
In samples of breast cancer patients lymph nodes, Lee and his colleagues identified unique patterns of immune cells. When the researchers compared the immune profiles to whether a patients cancer returned within five years, they could divide the patients into two groups. The group with what Lee termed a "favorable" immune profile had an 85 to 90 percent chance of being disease-free after five years. The group with an "unfavorable" immune profile had less than a 15 percent chance.

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...
