Thus assuming all MTC cases had calcitonin measured, MTC is 7 of 341 (2.05%) of the total thyroid cancer burden at the hospital and 7 of 2070 (0.338%) of all thyroid nodules.
Posttreatment surveillance of thyroid cancer is done with US of the thyroid bed as well as monitoring of tumor markers such as serum thyroglobulin and serum calcitonin.
