<abstract xmlns="http://www.w3.org/1999/xhtml"> Objective: The aim of this study was to analyze in parallel the 6th and the newest 7th AJJCC/UICC (American Joint Committee on Cancer/ International Union Against Cancer) staging system in order to highlight changes brought by the new staging system. <bold>Methods: </bold>We analyzed data obtained retrospectively from 134 hospitalized patients diagnosed with gastric carcinomas, who underwent surgery at the Surgery Clinics of the County Emergency Clinical Hospital of Tîrgu Mureș, Romania between 2008-2010.

The pN3 cases increased from 20.9% to 45.52%, because all cases classified as pN2 in the old staging system, became pN3 in the new system.
