Reatividade linfonodal com metástase cervical de tumor primário oculto: estudo de 24 pacientes

Abstract: RESUMO: Objetivo: Avaliar a reatividade linfonodal em pacientes com metástase cervical de tumor primário oculto. Método: Foram avaliados retrospectivamente 24 pacientes submetidos a esvaziamento cervical entre 1983 e 1995 devido à metástase de tumor primário oculto. Os cortes histológicos dos 601 linfonodos resultantes foram corados pela hematoxilina-eosina e avaliados à microscopia óptica. A reatividade linfonodal considerou a presença de hiperplasia paracortical, hiperplasia de centro germinativo e hiperplas… Show more

“…Lymph node reactivity, seen as paracortical or follicular hyperplasia, was related to the best prognosis in different studies 5,6,18 . In various studies there was no consensus on which type of reactivity has the best prognosis, or a method to classify heterogeneous reactivity.…”

“…The immune response, as well as anti-tumor action, is part of the modulation of angiogenesis and other related mechanisms to the invasion and growth of the neoplasms. Regional lymph nodes frequently present signs of reactivity, the meaning of which is still unknown 5,6 . This study aims to evaluate microvascular density and linfonodal reactivity in cervical metastases of occult primary tumors, relating these findings to other histological and clinical variables, considering that this disease is an adequate clinical model for the study of metastases.…”

“…O aumento de linfonodos em pacientes portadores de neoplasia maligna nem sempre é secundário ao comprometimento neoplásico desta estrutura, mas sim à hiperplasia linfonodal. Os linfonodos hiperplásicos são frequentemente encontrados durante os esvaziamentos cervicais, com significado clínico ainda não elucidado (AMAR A et. al., 2001).…”

“…Essa hiperplasia pode ser interpretada clinicamente como comprometimento neoplásico, com um índice de falso-positivo próximo de 25% (FEINMESSER R et. al., 1992), no entanto, o significado clínico desta hiperplasia ainda não está definido (AMAR A et. al., 2001).…”
