Study finds survival rates from GIST improving among African-Americans

New research published in the July issue of the Journal of the American College of Surgeons reveals that African Americans with gastrointestinal stromal tumors (GIST), a rare cancer that begins in the wall of the gastrointestinal tract, now have survival rates equivalent to those of Caucasians. Prior to 2000, African Americans were more likely to develop GIST and less likely to undergo surgical treatment for this type of cancer.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

Discovery of genetic key to breast cancer's ability to survive and spread

New research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) sheds light on a genetic function that gives breast cancer cells the ability to survive and spread to the bone years after treatment has been administered.

A new prostate cancer "homing device" for drug delivery

A new prostate cancer "homing device" could improve detection and allow for the first targeted treatment of the disease. A team of Purdue University researchers has synthesized a molecule that finds and penetrates prostate cancer cells and has created imaging agents and therapeutic drugs that can link to the molecule and be carried with it as cargo.
