Can previous thyroid scan induce cytogenetic radioadaptive response in patients treated by radioiodine for hyperthyroidism?
Background: Induction of radioadaptive responses in cells pretreated with a low dose radiation before exposure to a high dose is well documented by many investigators. The aim of this study is to determine the frequency of chromosomal aberration in peripheral blood lymphocytes of patients treated by radioiodine (131I) for hyperthyroidism, with or without previous thyroid scan with 99mTc. Materi...
متن کاملMetastatic follicular carcinoma of the thyroid: reappearance of radioiodine uptake.
Dedifferentiation of well-differentiated thyroid carcinoma is a well-known phenomenon that may lead to the disappearance of radioiodine uptake in tumors and the inability to treat patients with radioiodine. We report a patient in whom the 131I uptake progressively diminished to such low levels after a cumulative dose of 31.5 GBq that further 131I administration was considered nonbeneficial. The...
متن کاملPregnancy outcome after treatment with radioiodine for differentiated thyroid carcinoma.
The aim of the study was to investigate the influence of radioiodine (RAI) therapy on pregnancies and the health status of children born to mothers who had received therapeutic doses of I-131 for differentiated thyroid carcinoma (DTC). Gestational histories of 76 women treated for DTC from 1971-2005 were retrospectively analyzed. The outcome of 49 pregnancies after RAI was: 35 children (72%), 5...
متن کاملChallenges and strategies on radioiodine treatment for differentiated thyroid carcinoma.
OBJECTIVE Radioiodine ((131)I) is considered an effective and low-risk therapeutic radionuclide for differentiated thyroid carcinoma (DTC); however, dilemmas exist in the optimization of indications, pre-treatment thyroid stimulating hormone (TSH) stimulation, dose decision, as well as in the treatment of (131)I-refractory disease. Refined strategies on (131)I treatment for DTC based on late ev...
متن کاملRadioiodine avid adenomatous colon polyp in a post-treatment whole body radioiodine scan
A 47 year old female with papillary thyroid carcinoma was referred to our department for post-treatment whole body iodine scanning. The acquired images revealed a focal zone of intense radiotracer uptake in the right lower quadrant of the abdomen. SPECT/CT fused slices showed a focal zone of the radioiodine (131I) uptake in the right colon wall. Colonoscopy revealed a pedunculated po...
