Radiotherapy: dosimetry planning

The results of treatment of 142 case histories of 125 patients who had been treated with radioactive iodine at the Medical Radiological Research Center of Russian Academy of Medical Sciences from 1983 to 1999 are given in the presentation. Among the patients, 35 cases of diffuse toxic goiter with signs of thyrotoxicosis of a mild degree, 25 cases of diffuse toxic goiter with severe thyrotoxicosis, 6 cases of differentiated thyroid cancer with metastases to lymph nodes of the neck, 30 cases of thyroid cancer with metastases to lymph nodes of the neck and lung and 1 case of thyroid cancer with metastases to bones were diagnosed. Curves for accumulation and elimination of the radioiodine from the thyroid were built up for every patient. The curves show the true speed of accumulation of the iodine in the thyroid tissue and its elimination from the thyroid gland or its remnants, as well as from the whole body. (authors)
