"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.
