Health-related quality-of-life study in patients with carcinoma of the thyroid after thyroxine withdrawal for whole body scanning.

Objectives/hypothesis: The authors studied the change of health-related quality of life (HR-QOL) in patients with differentiated thyroid carcinoma (DTC) with thyroxine (T4) withdrawal in preparation for whole body radioactive iodine scanning.

Study Design: Seventy-eight patients with DTC and history of radioactive iodine (RAI) ablation were prospectively recruited. They completed the Functional Assessment of Cancer Treatment-General (FACT-G) questionnaire on weeks 0, 2, and 4 after T4 withdrawal with corresponding checking of serum thyroid-stimulating hormone (TSH).

Pregnancy outcome after diagnosis of differentiated thyroid carcinoma: no deleterious effect after radioactive iodine treatment.

Purpose: Thyroid carcinoma is the second most common malignancy in young women, after breast cancer, aged 15-34 years in Hong Kong. Radioiodine or (131)I (RAI) has been confirmed as a useful treatment in the management of differentiated thyroid carcinoma (DTC). Serious concerns have been raised of the potential risks on subsequent pregnancies.
