A diagnosis of thyroid cancer may be treated with removal of the thyroid gland. Which hormone or hormones may now be deficient? Considering each hormone individually, which ones should be restored and why? Explain any age-related considerations. Which nonthyroid hormone may be affected by careless thyroidectomy? Explain your answer, indicating whether or not it is critical to maintain this
hormone.
What will be an ideal response?
The thyroid gland is the source of thyroid hormones and calcitonin. Thyroid hormones should be replaced in
children to maintain normal growth and in adults to maintain quality of life. Calcitonin replacement is not
necessary in adults, because parathyroid hormone and calcitriol should be unaffected, and they are sufficient to
maintain normal calcium balance. It is unclear how important calcitonin replacement may be in children. Careless
thyroidectomy could result in removal of parathyroid glands. If parathyroid hormone is not restored, death results.
