They build "spaghetti models" of cancer progression similar to meteorologists' models for predicting hurricane paths Using mathematical models, researchers in the Integrated Mathematical Oncology (IMO) program at Moffitt Cancer Center are focusing their research on the interaction between the tumor and its microenvironment and the "selective forces" in that microenvironment that play a role in the growth and evolution of cancer. According to Alexander R. A. Anderson, Ph.D., chair of...

Presentations at the 4th IMPAKT Breast Cancer Conference New findings presented at Europe's leading breast cancer translational research conference this year shed new light on the many biological differences between individual breast cancers. Focused on the biological features that make tumors more or less sensitive to important therapies, the new studies will help doctors make crucial choices about the most appropriate treatment for millions of patients. "Despite major advances in...

UCSF Visualization Shows Why Immune System Fails to Kill Tumors in Mice A pioneering approach to imaging breast cancer in mice has revealed new clues about why the human immune system often fails to attack tumors and keep cancer in check. This observation, by scientists at the University of California, San Francisco (UCSF), may help to reveal new approaches to cancer immunotherapy. Published in the journal Cancer Cell last month, the work shows that the body's natural defenses trip over...

Abdominal tumors involving both roots of the celiac and superior mesenteric artery (SMA) are deemed unresectable by conventional surgical methods, as removal would cause necrosis of the organs that are supplied by those blood vessels. A case report published in the journal American Journal of Transplantation presents a novel surgical technique that enables surgeons to remove tumors that are unresectable by the usual surgical techniques. Led by Tomoaki Kato, MD, FACS, of Columbia...

Worrywarts, fidgety folk and the naturally nervy may have a real cause for concern: accelerated cancer. In a new study led by researchers at the Stanford University School of Medicine, anxiety-prone mice developed more severe cancer then their calm counterparts. The study, to be published online April 25 in PLoS ONE, found that after hairless mice were dosed with ultraviolet rays, the nervous ones – with a penchant for reticence and risk aversion – developed more tumors and...

Researchers say drug based on their discovery might target several tumor types A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida. Their study suggests other forms of cancer may also be driven by this gene, matrix metalloproteinase-10 (MMP-10). The study, published in the journal PLoS ONE on April 24, shows that MMP-10 is a growth factor secreted and then used by...

New research confirms an association between smoking and a reduced risk for a rare benign tumor near the brain, but the addition of smokeless tobacco to the analysis suggests nicotine is not the protective substance. The study using Swedish data suggests that men who currently smoke are almost 60 percent less likely than people who have never smoked to develop this tumor, called an acoustic neuroma. But men in the study who used snuff, which produces roughly the same amount of nicotine in...

Presentations at the 3rd European Lung Cancer Conference Several new studies that may help doctors tailor lung cancer treatment to the characteristics of individual patients and of their tumors are being presented at the 3rd European Lung Cancer Conference in Geneva. "A major goal of lung cancer treatment is to tailor the treatment to the individual," says Dr Fiona Blackhall from The Christie NHS Foundation Trust in Manchester, UK. "The studies that will be presented at ELCC 2012 are...

Combining two strategies designed to improve the results of cancer treatment — antiangiogenesis drugs and nanomedicines — may only be successful if the smallest nanomedicines are used. A new study from Massachusetts General Hospital (MGH) researchers, appearing in Nature Nanotechnology, finds that normalizing blood vessels within tumors, which improves the delivery of standard chemotherapy drugs, can block the delivery of larger nanotherapy molecules. "We found that vascular...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
