Studies have found that prostate cancer is overdiagnosed in up to 42 percent of cases, prompting men to receive unnecessary treatment that can cause devastating side effects, including impotence and incontinence. Now, researchers at Fred Hutchinson Cancer Research Center and the University of Washington have developed a personalized tool that can predict the likelihood of prostate cancer overdiagnosis. They announced their findings this week in the online issue of the Journal of the National Cancer Institute.

A new technique for studying the structure of the childhood RSV virus and its activity in living cells could help researchers unlock the secrets of the virus, including how it enters cells, how it replicates, and perhaps why certain lung cells escape the infection relatively unscathed.
Patients with tongue cancer who started their treatment with a course of chemotherapy fared significantly worse than patients who received surgery first, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.
Biologists at The Johns Hopkins University have discovered that low oxygen conditions, which often persist inside tumors, are sufficient to initiate a molecular chain of events that transforms breast cancer cells from being rigid and stationery to mobile and invasive. Their evidence underlines the importance of hypoxia-inducible factors in promoting breast cancer metastasis.
A team of researchers studying plants has assembled the largest dated evolutionary tree, using it to show the order in which flowering plants evolved specific strategies, such as the seasonal shedding of leaves, to move into areas with cold winters. The results will be published Dec. 22 in the journal Nature.

A genetic trait known to make some people especially sensitive to stress also appears to be responsible for a 38 percent increased risk of heart attack or death in patients with heart disease, scientists at Duke Medicine report.
In some mountain ranges, Earth’s warming climate is driving rabbit relatives known as pikas to higher elevations or wiping them out. But University of Utah biologists discovered that roly-poly pikas living in rockslides near sea level in Oregon can survive hot weather by eating more moss than any other mammal.
A CU Cancer Center study published today in the journal Stem Cells shows that progenitor cells that create dangerous, muscle-invasive bladder cancer are different than the progenitor cells that create non-muscle invasive bladder cancer. Though these two cancers grow at the same site, they are different diseases.
A University of Colorado Cancer Center study shows that ALK and ROS1 gene rearrangements known to drive subsets of lung cancer are also present in some colorectal cancers. These results imply that drugs used to target ALK and ROS1 in lung cancer may also have applications in this subset of colorectal cancer patients.

A Phase I trial of endoxifen, an active metabolite of the cancer drug tamoxifen, indicates that the experimental drug is safe, with early evidence for anti-tumor activity, a Mayo Clinic study has found. The findings indicate that Z-endoxifen, co-developed by Mayo Clinic Cancer Center and the National Cancer Institute (NCI), may provide a new and better treatment for some women with estrogen positive breast cancer and, in particular, for those women who do not respond to tamoxifen and aromatase inhibitors. Results of the first in-human trial were presented today during the 2013 San Antonio Breast Cancer Symposium.
