Guest guest Posted October 23, 2006 Report Share Posted October 23, 2006 When medical reality doesn't match the spin http://msnbc.msn.com/id/13421277/ Recent study shows the government is too eager to claim cancer success By Bazell Chief science and health correspondent, NBC News We're making great progress against cancer, right? The National Cancer Institute desperately wants you to believe that, even if it means spinning the scientific facts to fit the perception. The NCI is the federal government's lead organization in financing cancer research, with an annual budget of about $5 billion. Presentation of the results from a recent breast cancer study demonstrates the NCI's eagerness to proclaim success no matter what the data show. Called the STAR trial, the study enrolled 20,000 healthy post- menopausal women for five years to compare two drugs, tamoxifen and raloxifene (sold under the trade name Evista), to determine which is better at reducing the risk for breast cancer. Scientists and journalists label such studies " prevention " trials. Unfortunately, nothing prevents breast cancer. Some drugs shift the odds, and the goal here was to determine which one is best. Reading a a press release issued by the NCI in April and listening to a telephone briefing, there was no doubt. Both drugs affected breast cancer incidence equally, but raloxifene has fewer side effects, according to the researchers. Bingo! A great result for women's health. Raloxifene, as headlines and news broadcasts across the country proclaimed, was the clear winner. Since the drug is already on the market to protect against bone loss why shouldn't eligible women, estimated to number 30 million, take it? Ambiguous results The problem? The detailed results of the study appearing in this week's issue of the Journal of the American Medical Association differ substantially from the interpretation pushed by the press release. Both drugs have side effects and the study offers little clarity about which one is best. Most troubling for raloxifene, it brings a higher incidence of a breast condition called DCIS (or ductal carcinoma in situ). Oncologists debate whether this is truly breast cancer or a pre- cancerous condition. But tens of thousands of women a year require surgery (often mastectomy) and radiation to treat DCIS so anyone would think twice before taking a drug that might increase the risk. This equivocal result is especially troubling for the NCI because of the history of the effort to find a breast cancer " prevention " pill. In 1998 with great fanfare the NCI released results of a trial that compared tamoxifen to a placebo. Tamoxifen clearly reduced the risk of breast cancer. A government press release called it " an historic step toward more effective prevention of breast cancer. " But women and their doctors did not buy into the concept. Tamoxifen increases the risk for blood clots and uterine cancer and few healthy women wanted to take a pill every day. So the NCI really wanted to prove that raloxifene could be an acceptable alternative. But taxpayers spent $88 million (and raloxifene manufacturer Eli Lilly put in another $30 Million) for the ambiguous result. +++++++++++++++++++++++++++++++++++++++++++++++ BREAST CANCER OPTIONS now has a DISCUSSION FORUM page on our web site: http://www.breastcanceroptions.org/DiscussionForum.asp.

Guest guest Posted October 23, 2006 Report Share Posted October 23, 2006 Thanks nne! I am amazed by those news. Actually, after reading the links in this article, I keep wodering in who to believe... No wonder I had so many reservations about ths treatment. So, one more reason to not expose myself to so many yeras of tamoxifen. There is a link there that talks about how efective is tamox for cancer prevention. Disturbing.
