Compared to traditional mammography, 3D mammography—known as digital breast tomosynthesis—found 22 percent more breast cancers and led to fewer call backs in a large screening study at the Hospital of the University of Pennsylvania (HUP), researchers reported at the annual meeting of the Radiological Society of North America (RSNA). The University of Pennsylvania is home to the Abramson Cancer Center.
A new class of drugs reduced the risk of patients contracting a serious and often deadly side effect of lifesaving bone marrow transplant treatments, according to a study from researchers at the University of Michigan Comprehensive Cancer Center. The study, the first to test this treatment in people, combined the drug vorinostat with standard medications given after transplant, resulting in 22 percent of patients developing graft-vs.-host disease compared to 42 percent of patients who typically develop this condition with standard medications alone. Results of the study appear in The Lancet Oncology.
Many cancers have adapted to cope with high levels of immune system-produced free radicals, also referred to as reactive oxygen species, by overproducing antioxidant proteins. One of these proteins, superoxide dismutase 1 (SOD1), is overproduced in lung adenocarcinomas and has been implicated as a target for chemotherapy. In the Journal of Clinical Investigation, researchers from Northwestern University (home of the Robert H. Lurie Comprehensive Cancer Center) report the effects of a SOD1 pharmacological inhibitor on non-small-cell lung cancer (NSCLC) cells.
Reporting in the Journal of Clinical Investigation, researchers at M.D. Anderson Cancer Center performed an in depth analysis of Treg populations in melanoma patients undergoing HD IL-2 therapy. The authors identified a distinct population of Treg cells that expressed the inducible T cell costimulator (ICOS) that was highly proliferative following the first cycle of HD IL-2.
Cyclin D1, a protein that helps push a replicating cell through the cell cycle, also mediates the processing and generation of mature microRNA (miRNA), according to new research from the Kimmel Cancer Center at Thomas Jefferson University published November 29 in Nature Communications. The research suggests that a protein strongly implicated in human cancer also governs the non-protein-coding genome. The non-coding genome, previously referred to as junk DNA, makes up most of the human genome, and unlike the coding genome, varies greatly between species.
