5-fluorouracil-induced increase of total serum thyroxine and triiodothyronine
Abstract:
Total serum thyroxine and triiodothyronine levels in a group of 15 patients with advanced mammary carcinoma significantly increased during weekly treatment with 5-fluorouracil, whereas serum free thyroxine levels and serum thyroid stimulating hormone levels were unchanged. No clinical signs of hyperthyroidism in these treated patients have been observed.
