Resumo

Até à entrada em vigor da última revisão da classificação TNM da UICC-AJCC, o carcinoma da junção esófago-gástrica tanto podia, para propósitos de estadiamento, ser classificado como esofágico ou gástrico, facto que, por si só, gerava uma série de incoerências na abordagem destas neoplasias. O objetivo deste trabalho é então procurar clarificar o enquadramento do carcinoma da junção esófagogástrica, no que diz respeito ao estadiamento, pretendendo os autores responder à questão “O que são na realidade os carcinomas da junção esófago-gástrica à luz do sistema atual da classificação TNM da UICC?”. Foi para isso realizada uma pesquisa bibliográfica na base de dados PubMed, com seleção dos artigos relevantes para o tema. Segundo a 1a edição da classificação TNM da UICC-AJCC, neoplasias cujo epicentro se localize no esófago distal / torácico inferior, na junção esófago-gástrica ou mesmo nos cinco cm proximais do estômago e invadam a junção esófago-gástrica, deverão ser classificadas, para propósitos de estadiamento, como adenocarcinomas do esófago. Apesar da nova classificação uniformizar o estadiamento dos carcinomas da junção esófago-gástrica, eliminando poten- cialmente as divergências relativas a esta entidade, futuras revisões poderão esclarecer se ela é adequada a esta neoplasia ou se, em alternativa, se justifica a criação de um sistema de estadiamento próprio.

Palavras-chave: adenocarcinoma; junção esófago-gástrica; estadiamento das neoplasias; AJCC; 7a edição.
