Resumo: | Unilateral or bilateral neck dissection must be considered in the treatment of laryngeal cancer AIM: To evaluate the prevalence of contralateral metastases in larynx cancer and distribution of these metastases according to lymph node levels in the neck. METHOD: Retrospective longitudinal study of 272 charts from patients with squamous cell cancer of the larynx treated between 1996 and 2004; and we selected 104 surgical cases submitted to neck dissection. We evaluated the incidence of bilateral or contralateral metastases, according to the location and extension of the primary tumor, considering the anatomical sub-sites and the midline. RESULTS: Contralateral metastases in lateral tumors were observed in 3.5% of glottic lesions and in 26% of supraglottic lesions. Contralateral metastases were uncommon in N0 patients. Lymph nodes levels IIa and III were the most commonly involved in the neck. CONCLUSION: In lateral glottic tumors there is no need for elective contralateral neck dissection. In supraglottic lesions without ipsilateral metastases, the incidence of hidden metastasis does not justify elective contralateral dissection. The midline is not a reliable indicator of the risk of contralateral laryngeal tumors. |

OBJETIVO: Avaliar a prevalência e localização de metástases linfonodais bilaterais ou contralaterais nos tumores de laringe. CASUÍSTICA E MÉTODO: Estudo longitudinal retrospectivo de 272 prontuários de pacientes com carcinoma epidermoide de laringe tratados entre 1996 e 2004, selecionados 104 submetidos à cirurgia com esvaziamento cervical. Avaliada a incidência de metástases bilaterais ou contralaterais, de acordo com a localização e extensão do tumor primário, considerando os subsítios anatômicos e a linha mediana. RESULTADOS: A prevalência de metástases contralaterais nos tumores lateralizados foi de 3,5% nas lesões glóticas e 26% nas lesões supraglóticas. As metástases contralaterais foram infrequentes nos casos N0. Tanto no esvaziamento eletivo como no terapêutico, os níveis linfonodais IIa e III foram os mais acometidos. CONCLUSÃO: Nas lesões glóticas lateralizadas, mesmo nos tumores transglóticos, não há necessidade de esvaziamento contralateral eletivo. Nas lesões da supraglote sem metástases ipsilaterais, a incidência de metástases ocultas não justifica o esvaziamento eletivo contralateral. A linha mediana não é um indicador fidedigno do risco de metástases contralaterais nos tumores da laringe.UNIFESPHospital HeliópolisUSPUNIFESPSciELOAssociação Brasileira de Otorrinolaringologia e Cirurgia CervicofacialUniversidade Federal de São Paulo (UNIFESP)Hospital HeliópolisUniversidade de São Paulo (USP)Amar, Ali [UNIFESP]Chedid, Helma MariaFranzi, Sergio AltinoRapoport, Abrão [UNIFESP]2015-06-14T13:43:40Z2015-06-14T13:43:40Z2012-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion7-10application/pdfhttp://dx.doi.org/10.1590/S1808-86942012000200002Brazilian Journal of Otorhinolaryngology.
