Task: Answer Verification
Input (English): Question: Does complete surgical lymph node resection prevent authentic recurrences of medullary thyroid carcinoma?
Answer: 3.3% of patients not cured at the last visit had a recurrent MTC. This recurrence occurred whatever the stage, and even if the primary surgery for MTC was a priori complete. These results emphasize the need for a regular biochemical follow-up because recurrence may appear many years after the initial surgery.
Output (English): no
