Abstract

Evaluation of cervical lymph nodes for staging and surgical planning in thyroid cancer is necessary to determine the extend of surgery. CND (central neck dissection) in differentianted thyroid cancer remains controvertial due to low potential benefits and increase complications such as dysphonia, hypoparathyroidism (temporal/permanent).There is a large proportion of patients with subclinical disease during thyroidectomy (50 %). the presence of metastatic positive lymph in the central compartment during the procedure increases the risk of local recurrence (N1 31% - N0 8%). There is debate whether if its necessary the PND (prophylactic neck dissection) during thyroidectomy in PTC (papillary thyroid cancer), because do not change survival rate ,but increases local recurrence. The study of Antonio Sitges ( Nodal Yield, morbidity, and recurrence after CND for papillary thyroid carcinoma) proved prevalence nodal metastasis rate of 60% in those patients with no local recurrences after thyroidectomy of PTC. Tissel study meticulous CND improves the prognosis PTC even without the use of I 131. To date there is no study has demonstrated significantly reduced recurrence or mortality rates with PND. the controvercy remains whether perform or not PND in PTC.
