Prevention of Liver Metastases by Intravenous Radioisotopes

Abstract
With an intravenously administered therapeutic dose of p32-tagged colloidal chromic phosphate, the incidence of metastasis was reduced from 75% in control animals to 31% in rats receiving the chromic phosphate shortly after injection of tumor cells in the portal vein. Pretreatment of the animals with radiotherapy appeared to be ineffective.
