Low-activity I implantation into VX tumor rabbits and quantitative evaluation of the precise therapeutic effect.

There is still controversy about quantitatively evaluating the therapeutic effect of radioactive low-activity iodine125 seeds (I seeds). In the present study, a paired VX tumor model in a rabbit hind leg muscle was established, which is virus-induced anaplastic squamous cell carcinoma characterized by hypervascularity, rapid growth and easy propagation in the skeletal muscle. I seeds with 0.
