Iodine-131 in breast milk following therapy for thyroid carcinoma
- Royal Perth Hospital (Australia); and others
This study evaluates breast milk secretion of {sup 131}I following therapeutic adminstration of 4000 MBq of {sup 131}I-iodide during lactation. Breast milk {sup 131}I activity concentration was measured over a 32-day period. Dosimetry calculations were undertaken to estimate the period for discontinuation of breast feeding and the equivalent dose to the breasts. To achieve an infant effective dose <1 mSv and an infant thyroid dose <10 mSv, breast feeding would need to be discontinued for at least 52 days. The estimated equivalent dose to the breasts was 1.6 Gy. It is suggested that {sup 131}I-iodide adminstration is not undertaken during lactation and that breast feeding is discontinued several days prior to administration. 26 refs., 2 figs., 2 tabs.
