'No Longer a Death Sentence'

Premium

A new study published in the Journal of Clinical Oncology shows that nine out of every 10 children with leukemia survive their disease, reports Bloomberg's Nicole Ostrow. Five-year survival rates for acute lymphoblastic leukemia in children rose to 90 percent in the period of 2000 to 2005, from 84 percent in 1990 to 1994, Ostrow says. "Improved drug combinations and better ways to determine treatment needs helped boost survival," she adds. "Identifying subsets of leukemia and medications, such as Novartis' Gleevec that specifically target those groups will help improve survival even more."

Researchers Develop Polygenic Risk Scores for Dozens of Disease-Related Exposures

With genetic data from two large population cohorts and summary statistics from prior genome-wide association studies, researchers came up with 27 exposure polygenic risk scores in the American Journal of Human Genetics.

US Survey Data Suggests Ancestry Testing Leads Way in Awareness, Use of Genetic Testing Awareness

Although roughly three-quarters of surveyed individuals in a Genetics in Medicine study reported awareness of genetic testing, use of such tests was lower and varied with income, ancestry, and disease history.
