Study could aid in development of ‘liquid biopsy’ screening, diagnostic tests for bladder cancer

Bladder cancer is the fourth most common non-skin cancer. But there is no good screening test for it, and there has been limited progress in characterizing how aggressive an individual’s bladder cancer will be. Loyola researchers studied microscopic droplets, called exosomes, that are shed by cancer cells and are found in urine. Understanding the biology of exosomes could lead to the development of a screening test, which would require a simple urine sample, said lead researcher Gopal Gupta, MD…

Epigenetics of breast cancer family history

Researchers from the Columbia University Medical Center in New York have now examined whether a specific epigenetic modification (more specifically, methylation of the DNA) can be associated to breast cancer family history in unaffected women from high-risk breast cancer families. This important work suggests that the levels of DNA methylation in white blood cells from cancer-free women could be one of the factors playing a role in the clustering of breast cancer in families with extensive cancer histories within its members. source : http://www.sciencedaily.com/releases/2014/01/140107172017.htm

Less can be more when removing lymph nodes during breast cancer surgery

In the Oct. 2 edition of the Journal of the American Medical Association, lead author Dr. Roshni Rao, associate professor of surgery at UT Southwestern, and other investigators from the Harold C. Simmons Cancer Center reviewed studies on patient outcomes of women who had received various forms of surgical treatment, ranging from removal of one lymph node to prevent the spread of breast cancer to removing the entire network of lymph nodes spanning the armpits…
