¹⁶⁶Holmium-Containing Glass for Internal Radiotherapy of Tumors
Abstract
Aluminosilicate glass containing the β-emitter 166Ho was tested for tumor cell killing effectiveness with the BT-20 human mammary carcinoma cell line as a model. Incubation of BT-20 cells with 166Ho glass partially inhibited DNA replication and completely blocked growth in cells located within 1.0 mm of the radioactive fiber. Growth of BT-20 tumor xenografts in nude mice was dramatically inhibited by injection of 2-5 μm fragments of 166Ho glass (200 μ Ci/tumor). The results suggest that 166Ho glass would be an effective modality for deposition of intense β- radiation for localized internal radiotherapy of tumors.
