Evaluate whether combining subtotal thyroidectomy with a low-dose injection of iodine-131 induces neoplastic transformation in rat thyroid glands.
Subjected rat models to subtotal thyroidectomy.
Administered an internal dose of one microcurie of iodine-131 (I-131).
Assessed thyroid tissues histologically for tumor development and neoplastic changes.
Subtotal thyroidectomy combined with one microcurie of I-131 exposure led to the induction of thyroid neoplasms.
Demonstrated that physical tissue reduction enhances susceptibility to radiation-associated neoplastic changes in the residual thyroid gland.
