Sao Paulo Medical Journal , 1994, DOI: 10.1590/S1516-31801994000300004
Abstract: to determine the prognostic significance of desmoplasia in metastatic lymph nodes of squamous cell carcinoma of the oral tongue and floor of mouth, 37 cases of this disease were studied. desmoplasia was present in 59,4% of the cases and associated extracapsular spread in 40,5%. the association of desmoplasia with large lymph node involvement occurred in 59,4%. these relationships were statistically significant (p= 0,002 and 0,0069). the results obtained suggest that desmoplasia is a bad prognosis associated factor.

Abstract: OBJETIVO: Avaliar os resultados do tratamento dos pacientes com metástases cervicais bilaterais de carcinoma epidermóide das vias aerodigestivas superiores. FORMA DE ESTUDO: Série de casos retrospectiva. CASUíSTICA E MéTODO: Revis o dos prontuários de 855 pacientes com carcinoma epidermóide de boca, orofaringe, hipofaringe e laringe submetidos à ressec o do tumor primário e esvaziamento cervical radical entre 1977 e 1996. Foram selecionados 96 pacientes com metástases bilaterais confirmadas histologicamente, dos quais 73 foram submetidos inicialmente ao esvaziamento cervical bilateral (ECB) e 23 pacientes que se submeteram ao esvaziamento unilateral e, posteriormente, desenvolveram recidiva cervical contralateral. A evolu o dos pacientes foi avaliada por meio da sobrevida livre de doen a e do controle cervical. RESULTADOS: Entre os 23 pacientes submetidos ao esvaziamento unilateral (pN+) que desenvolveram recidiva contralateral, foram resgatados 18 pacientes. O controle da doen a no pesco o em 2 anos foi alcan ado em 46% dos pacientes. Entre os 73 pacientes submetidos ao esvaziamento bilateral (pN2c) ocorreram 12 casos de recidivas cervicais, dos quais apenas 3 foram resgatados. O controle da doen a no pesco o em dois anos foi alcan ado em 77% dos pacientes. A sobrevida livre de doen a foi semelhante entre os 2 grupos, apesar da diferen a observada na taxa de controle cervical. CONCLUS O: O esvaziamento bilateral em tempo único apresentou melhor controle da doen a no pesco o, mas n o alterou a sobrevida livre de doen a neste grupo de pacientes. A despeito do controle da doen a cervical ser obtido na maioria dos pacientes, apenas um ter o daqueles com metástases bilaterais apresentaram doen a controlada após 2 anos.
