Abstract

The 7th edition of the UICC/AJCC TNM, and a new revision of the Japanese Classification for Gastric Cancer and Treatment Guidelines (Japanese Gastric Cancer Association) have been available since the beginning of 2010. One of the most important changes consists on the redefining and simplification of type D1/D2 lymphadenectomy depending on the type of gastrectomy performed (previously it depended on the location of the primary tumour), and the adoption of numeric criteria of TNM-7th Edition to evaluate the level of lymph node involvement (before, according to the anatomical location of the groups as regards the primary tumour). These changes attempt to make therapeutic management easier and a more uniform comparison of results between countries. The importance of these modifications in both systems justifies this exhaustive analysis and update of the new concepts for a correct management of gastric cancer.

Resumen

Desde inicios de 2010 han entrado en vigor la 7.a edición del TNM (UICC/AJCC) y una nueva revisión de la Japanese Classification for Gastric Cancer y de la Treatment Guidelines (Japanese Gastric Cancer Association). Unas de las modificaciones más importantes consisten en la redefinición y simplificación de los tipos de linfadenectomía D1/D2 en función del tipo de gastrectomía realizada (anteriormente en función de la localización del tumor primario) y en la adopción del criterio numérico de la 7.a edición del TNM para evaluar el grado de afectación ganglionar (antes según la localización anatómica de los grupos respecto al tumor primario). Estos cambios pretenden facilitar el manejo terapéutico y la comparación de los resultados de una forma más uniforme entre países. La relevancia de estas modificaciones en ambos sistemas justifica este análisis exhaustivo y la actualización de los nuevos conceptos para un manejo correcto del cáncer gástrico.
