Title in Portuguese
"Expressão das metaloproteinases MMP-2, MT1-MMP e TIMP-2 e aspectos clinicopatológicos no carcinoma medular da glândula tireóide: implicações prognósticas"
Keywords in Portuguese
Carcinoma medular
Gelatinase A
Imunohistoquímica
Inibidor de metaloproteinase-2 tecidual
Metaloproteases
Neoplasias da Glândula Tireóide
Prognóstico
Abstract in Portuguese
Metaloproteinases (MMP) são enzimas proteolíticas, fundamentais à carcinogênese. Evoluções de 37 pacientes operados por carcinomas medulares da tireóide foram comparadas com dados clinicopatológicos e expressões imuno-histoquímicas de MMP-2, MT1-MMP e TIMP-2 em seus espécimes neoplásicos. Condições clínicas finais foram correlacionadas com os aspectos clinicopatológicos: exame físico cervical positivo, sintomas sistêmicos, diâmetro tumoral, extensão neoplásica para a cápsula tireóidea, extensão tumoral para tecidos adjacentes, invasão vascular, metástases cervicais, estádio TNM, evidências de doenças cervical e/ou a distância. Expressões de MMP-2 e MT1-MMP foram correlacionadas à evolução clínica e maior proporção de TIMP-2, em relação à MMP-2, correlacionou-se a benefícios prognósticos
Title in English
Expression of matrix metalloproteinases MMP-2, TIMP-2 e MT1-MMP and clinicopathologic aspects in medullary thyroid carcinoma: prognostic implications
Keywords in English

Metalloproteases
Prognosis
Thyroid neoplasms
Tissue Inhibitor of Metalloproteinase-2
Abstract in English
Metalloproteinases (MMP) are proteolytic enzymes, fundamental to carcinogenesis. Outcome of 37 patients operated on due to medullary thyroid carcinomas were compared to clinicopathologic data and immunohistochemistry expression of MMP-2, MT1-MMP and TIMP-2 in their neoplastic specimens. Final clinical conditions were related to the clinicopathologic aspects: clinical features, systemic symptoms, tumor size, tumor extension to thyroid capsule, tumor extension to adjacent tissues, vascular invasion, cervical metastases, TNM stage and evidences of disease in the neck and/or distant metastases. Expression of MMP-2 and MT1-MMP were related to outcome and greater proportion of TIMP-2, over MMP-2, was related to prognostic benefits
