The value and prognostic significance of regional lymph node dissection in @entity1 with @entity259 remains a matter of controversy. The classification of the cervical lymph nodes and the extent of their resection in @entity1 with different @entity259 is also discussed. The aim of the paper was to present the space classification of regional lymph nodes, the incidence of their involvement and the extent of their resection in @entity1 with @entity259 . The results of multicenter studies have indicated that regional lymph node @entity3 in @entity1 with @entity259 , especially of a papillary type, have been frequent. Ipsilateral central, ipsilateral lateral, contralateral lateral, and mediastinal lymph nodes have been affected in 42-86%, 32-68%, 12-24%, and 3-20% of @entity1 respectively. In 20% of @entity1 only central lymph nodes have been affected, whereas in others @entity3 have been determined at least in 2 or more lymph node groups. Regional lymph nodes have been classified into Groups I-IV. Moreover, lymph node recurrences have been more frequent in @entity1 who either have not got the regional lymph nodes removed or have only enlarged ones determined as involved excised. Therefore, primary regional lymph nodes dissection is indicated. Elective resection of the lymph nodes of Group I (central lymph nodes) as a part of primary total thyroidectomy in @entity1 with @entity259 and more selective excision of the lymph nodes of Groups II-IV are recommended. The author has presented his own experience in lymph node dissection in @entity1 with @entity259 and compared it with other results.
