"The results show an anti-tumor interaction between ionizing radiation and angiostatin for four distinct tumor types, at doses of radiation that are used in radiotherapy," they said in the July 16 Nature. In tests on mice with various tumors, Weichselbaum and his team discovered that a dose of angiostatin that was ineffective on its own stopped tumor growth when combined with radiation. Researchers hope to begin testing angiostatin in humans in 12 to 18 months.
Thyroid Test Suggested for Women Over 50
Women older than 50 should be routinely screened for thyroid disease, according to new guidelines issued by the American College of Physicians and the American Society of Internal Medicine in the July 15 Annals of Internal Medicine. Such screening was previously recommended only for women with symptoms of thyroid disease.
