TG and thyroid cancer: In the management of thyroid cancer, points in favour of TT are: treatment of multicentric and bilateral tumors (as an hallmark of papillary carcinoma), improved disease-free survival, less local recurrence which are associated to reoperative complications and decreased survival, improved detection and elimination by radioiodine treatment of persistent and metastatic disease, improved surveillance by thyroglobulin dosage, contained primary surgical complications in high volume centres not differing from those observed after L and of course elimination of the risk of completion surgery.
