A study published in the journal Cancer Research last month suggests that the principle treatment for advanced prostate cancer may actually encourage prostate cancer cells to metastasize [1]. Researchers at The Johns Hopkins University School of Medicine focused on a gene called Nestin, which encodes an intermediate filament protein. Intermediate filaments are cytoskeletal or scaffolding structures found in cells that, in addition to maintaining cell shape, control a variety of cellular processes including proliferation, migration and survival [2]. Nestin gene expression also distinguishes stem cells from differentiated cells and has been shown to be activated in pediatric brain tumors and rhabdomyosarcomas (cancers that develop from skeletal muscle), central nervous system tumors and gastrointestinal stromal tumors [3-6].
March is National Colorectal Cancer Awareness Month
The goal of the annual National Colorectal Cancer Awareness Month is to make people aware of colorectal cancer and to encourage people to learn more about how to reduce their risk of colorectal cancer (CRC) through regular screening and a healthy lifestyle. The results of the National Health Interview Survey (NHIS) administered to 32,374 adults 18 years of age or older in 2000 showed that colorectal cancer screening is underused [1]. Just over 60% of adults had ever had colorectal cancer testing. Only 44% of men and 37% of women greater than 75 years of age were current for testing. Colorectal cancer screening is very important. If colorectal cancer is allowed to metastasize (meaning to spread to other parts of the body), the 5-year survival rate is less than 10%. However, if colorectal cancer is found early, the 5-year survival rate is greater than 90% [2].
