Prophylactic and Therapeutic Surgery in Familial Medullary Thyroid Cancer
Medullary thyroid cancer (MTC) is a neuroendocrine malignancy, which originates from C cells (parafollicular) of the gland. MTC is inherited in autosomal dominant pattern in 20–25% of patients with MEN syndromes. Familial MTC (FMTC) is the most frequent type of MEN syndromes.
The most accepted approach for deciding surgical treatment of the disease based on the precise polymer mutation within the douse factor occurring within the family and blood serum calcitonin levels.
RET mutations may be classified as highest, high, and moderate risk, concerning the potential risk for native and distant MTC metastases at an early age. The advised temporal order of excision relies upon proof of age-dependent and codon-specific progression of early MTC.
In conclusion, patients with inherited MTC ought to experience age-suitable thyroidectomy in view of RET mutational status to evade recurrences.
