Scientists at the UNC Lineberger Comprehensive Cancer Center report finding a new angiogenesis protein, SFRP2, found in the blood vessels of numerous tumor sites, including breast prostate, lung, pancreas, ovarian, colon, kidney tumors, and angiosarcomas. The scientists found that SFRP2 is a potent stimulator of angiogenesis. This protein may be a favorable target for inhibiting angiogenesis which would then "starve" the tumor of its blood supply, thus destroying the cancer.
A new study finds colorectal cancer incidence rates for both males and females increased in 27 of 51 countries worldwide between 1983 and 2002, and points to increasing Westernization as being a likely culprit. The rise was seen primarily in economically transitioning countries including Eastern European countries, most parts of Asia, and some countries of South America. The study is the first in a peer-reviewed journal to present colorectal cancer incidence trends across all five continents. It appears in the June 2009 issue of Cancer Epidemiology Biomarkers and Prevention. An accompanying editorial says the rise points toward a failed early detection and prevention strategy as well as failure to address lifestyle and dietary challenges of urbanization that affect most of the globe.
