BACKGROUND: Incidence and pattern of lymph node @entity3 (LNM) were evaluated in 35 @entity1 who underwent primary surgery for @entity3557 . METHODS: Total thyroidectomy with systematic cervicocentral lymphadenectomy was performed routinely. Additionally, 22 @entity1 underwent lymphadenectomy of the ipsilateral cervicolateral compartment. Sternotomy was performed in four @entity1 . RESULTS: Primary @entity5 status was: @entity2558 , n = 7; pT2, n = 12; @entity1803 , n = 4; pT4, n = 12. Twenty-four @entity1 had LNM in the ipsilateral cervicocentral compartment ( @entity2558 , n = 2; pT2, n = 8; @entity1803 , n = 4; pT4, n = 10). Nineteen had LNM in the ipsilateral cervicolateral compartment ( @entity2558 , n = 4; pT2, n = 6; @entity1803 , n = 2; pT4, n = 7). Contralateral cervicocentral LNM was restricted to @entity1 with @entity1803 @entity5 (n = 2) or pT4 @entity5 (n = 3). No @entity1 had LNM in the contralateral cervicolateral compartment. Only one @entity1 ( @entity1803 @entity5 ) had mediastinal LNM. CONCLUSION: The cervicocentral compartment was most commonly involved with @entity3 , although the ipsilateral cervicolateral compartment was almost as often affected. In some @entity1 ipsilateral cervicolateral LNM was present in the absence of cervicocentral LNM. Contralateral cervicolateral and upper mediastinal LNM, however, were rare. This study helps to plan radical surgery for @entity3557 .
