London, July 10 (Bloomberg) -- Zeneca Group Plc's tamoxifen drug has been shown to have no effect in preventing breast cancer in women with a family history of the disease, according to two studies published in today's edition of the Lancet magazine, The Daily Telegraph reported. The studies contradict a 30 million pound ($49 million) U.S. trial of the drug whose authors said in April they had found ''a dramatic advantage'' for women using tamoxifen, and that the anti-oestrogen drug could halve the risk of breast cancer, the paper said. A British study begun in 1986 and led by Trevor Powles of the Royal Marsden Hospital reports that of 2,500 women with a family history of breast cancer, the drug and placebo groups were equally likely to develop the disease; a second Italian study of 5,500 women with hysterectomies also found no difference, the paper reported.
Treatments developed by Genentech Inc., Eli Lilly & Co., Bristol-Myers Squibb Co. and others offer hope in the battle to fight and prevent breast cancer, according to studies released May 18 at a medical meeting in Los Angeles. (Daily Telegraph 7/10 p. 6 www.telegraph.co.uk)
