Usefulness of histologic differences and perivascular infiltration for preoperative T staging of advanced gastric cancer using computed tomography.

Purpose: This study aimed to determine whether histologic differences and perivascular infiltration are useful for clinical T staging of advanced gastric cancer (AGC).

Materials And Methods: This retrospective study included 160 patients with pathologically confirmed AGC who had available preoperative stomach computed tomography (CT). Using stomach CT, they were classified according to standard T stage, histologic T stage, and perivascular T stage.
