No racial difference for survival in African American versus Caucasian lung cancer patients
9/06/2013
According to the American Cancer Society, an estimated 160,340 lung cancer deaths occurred in the United States in 2012, accounting for 28 percent of all cancer deaths. While survival from lung cancer has improved since the early 1990s, racial differences in lung cancer survival persist such that blacks experience poorer 5-year survival for lung cancer compared to whites...
Scientists link a protein to initial tumor growth in several cancers
9/06/2013
A team led by scientists from The Scripps Research Institute (TSRI) have shown that a protein once thought to inhibit the growth of tumors is instead required for initial tumor growth. The findings could point to a new approach to cancer treatment. The study was published this week as the cover article of the journal Science Signaling...
Brain surgery could improve with laser-guided tool
9/06/2013
A new type of laser microscope may dramatically improve the accuracy of brain tumor surgery, according to a study reported this week in Science Translational Medicine. The new tool helps surgeons see clearly, while operating, where tumor tissue ends and healthy tissue begins...
Case Western Reserve researchers have identified a genetic factor that blocks the blood vessel inflammation that can lead to heart attacks, strokes and other potentially life-threatening events. The breakthrough involving Kruppel-like factor (KLF) 15 is the latest in a string of discoveries from the laboratory of professor of medicine Mukesh K...
Blind mole-rats are resistant to chemically induced cancers
9/06/2013
Like naked mole-rats (Heterocephalus gaber), blind mole-rats (of the genus Spalax) live underground in low-oxygen environments, are long-lived and resistant to cancer. A new study demonstrates just how cancer-resistant Spalax are, and suggests that the adaptations that help these rodents survive in low-oxygen environments also play a role in their longevity and cancer resistance...
Head, neck cancer care being concentrated at teaching hospitals, academic centers
9/05/2013
Head and neck cancer care is being concentrated at teaching hospitals and academic medical centers, according to a study by Elliot Abemayor, M.D., Ph.D., of the David Geffen School of Medicine at the University of California, Los Angeles, and colleagues...
New ovarian cancer gene found in mice
9/05/2013
Cancer Research UK scientists have discovered a gene that repairs damaged DNA is also linked to ovarian cancer in mice. They say if the gene - known as Helq - is faulty or missing, DNA errors accumulate as cells multiply, and this raises the chance of developing the cancer. They write about their findings in the September 4th online issue of Nature...

Colon cancer detected earlier with new method
9/05/2013
Researchers have found new techniques to spot certain gene variations that have been linked to colon cancer, and they say their new findings may soon allow doctors to identify the disease in the very first stages, potentially saving patients' lives...
Proteins in histone group might influence cancer development, study shows
9/05/2013
Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. A new study shows that a group of histones that are thought to behave the same actually are functionally distinct proteins. The findings by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J...
