[Value of spiral computed tomography for the preoperative detection of lymph node involvement in gastric cancer].

Background And Objective: Knowledge regarding the presence of metastatic lymph node in gastric cancer is of obvious importance when thinking of neoadjuvant therapy, yet it is full of uncertainty. Computed tomography (CT) is one of the first-line diagnostic tools, in spite of controversial results. We aimed to establish the performance of spiral CT in predicting lymph node involvement in gastric cancer.
