Worm genome offers clues to evolution of parasitism

The genome of a humble worm that dines on the microbial organisms covering the carcasses of dead beetles may provide clues to the evolution of parasitic worms, including those that infect humans, say scientists at the School of Medicine and the Max-Planck Institute for Developmental Biology in Germany. In a paper published in the current issue of Nature Genetics, the researchers reported finding some surprises as they have decoded the genome of the worm, a tiny nematode called Pristionchus pacificus.

New predictive tool can help determine treatment of breast cancer patients

A new predictive measurement, called a PEPI score, could bring good news to many women diagnosed with advanced breast cancer — a low PEPI (preoperative endocrine prognostic index) score could show that they have little risk of relapse and can safely avoid chemotherapy after surgery. For others, a high PEPI score could warn that the risk of relapse after breast surgery is large and indicate that careful follow-up and aggressive therapy may be needed, say researchers at the School of Medicine.

Racial disparities decline for cancer in Missouri

Cancer death rates in the United States are highest among African Americans, but a new report shows that in Missouri the disparity in cancer incidence and death between African Americans and whites is declining. As a result, cancer incidence (the rate of newly diagnosed cases) between the races is equal, although the death rate will probably remain higher for African Americans for some time.
