title: [Study of PBI 131 urinary elimination and collection located in breast carcinoma with or without metastasis].
abstract: In 9 female patients with breast cancer, we studied the diagnostic uptake of I131 at 24 hours, localization of I131 in the thyroid, primary breast tumor and its metastases, urinary excretion of I131 at 24 hours and PBI131, and came to the following conclusions: 1. Low normal values for uptake at 24 hours was observed as in previous studies. 2. There was no I131 uptake in the primary breast tumor or its metastases. 3. The sum of 24 hour uptake levels plus the urinary excretion at 24 hours were within normal limits. 4. Therefore, the relatively low uptake figures, which were repeatedly observed in these patients, are not due to competition between the thyroid uptake of I131 and the neoplastic tissue.
