Breast Cancer Survival Improves By Switching Drugs, Trial Shows
11/02/2011
Results from a long-term follow up from the Intergroup Exemestane Study's (IES) data published in the Journal of Clinical Oncology reveals that women's risk of dying from breast cancer can be reduced by changing to an aromatase inhibitor called exemestane after two to three years of tamoxifen treatment...
Link Between High Levels Of Master Heat Shock Protein And Poor Prognosis In Breast Cancer Patients
11/02/2011
Whitehead Institute scientists report that patients whose estrogen receptor (ER)-positive breast cancers have high levels of the ancient cellular survival factor heat shock factor 1 (HSF1) experience poor outcomes -- including increased mortality. According to the American Cancer Society, approximately two-thirds of breast cancer patients have ER-positive tumors...
Cancer Research May Advance With Fast New Method For Mapping Blood Vessels
11/02/2011
Like normal tissue, tumors thrive on nutrients carried to them by the blood stream. The rapid growth of new blood vessels is a hallmark of cancer, and studies have shown that preventing blood vessel growth can keep tumors from growing, too...
Golden Membranes Pave The Way For A Better Understanding Of Cancer And The Immune System
11/02/2011
Football has often been called "a game of inches," but biology is a game of nanometers, where spatial differences of only a few nanometers can determine the fate of a cell - whether it lives or dies, remains normal or turns cancerous. Scientists with the U.S...
Misshapen Red Blood Cells Detected Using Math And Light
11/02/2011
Misshapen red blood cells (RBCs) are a sign of serious illnesses, such as malaria and sickle cell anemia. Until recently, the only way to assess whether a person's RBCs were the correct shape was to look at them individually under a microscope - a time-consuming process for pathologists...
Regulatory T-Cell Clue May Help Prevent Graft-Versus-Host Disease
11/02/2011
Graft-versus-host disease (GVHD) is a serious risk in many kinds of cell transplants, including for stem cell transplants carried out when stem cells are partially depleted of conventional T cells, which play an important role in the immune system. Now, researchers at Moffitt Cancer Center have tested a process by which T regulatory cells (Tregs) can be "expanded" to help prevent GVHD...
Risk Of Suicide In Men With Prostate Cancer Could Be Lowered By New Findings
11/02/2011
Men with prostate cancer are twice as likely to commit suicide, but a method where they put intrusive thoughts into words may reduce this risk, reveals research at the Sahlgrenska Academy at the University of Gothenburg, Sweden. In a study at the University of Gothenburg's Sahlgrenska Academy, researchers surveyed the thoughts of 833 Swedish men before and after surgery for prostate cancer...
Cigarette smoking appears to impair pancreatic duct cell function -- even for those who quit --putting all smokers at risk of compromised digestive function regardless of age, gender and alcohol intake, according to the results of a study unveiled at the American College of Gastroenterology's (ACG) 76th Annual Scientific meeting in Washington, DC...
