Abstract
Radical surgery consisting of gastrectomy and D2 lymphadenectomy remains the standard procedure in the treatment of gastric cancer. To improve outcome, neoadjuvant treatment strategies with chemo- and/or radiotherapy regimes are employed. The optimal treatment plan and overall prognosis are critically dependent on accurate assessment of local invasion, tumor size, lymph node involvement, and the presence or absence of distant metastases. Total body computed tomography (CT), gastroduodenal endoscopy, and endoscopic ultrasonography have all been used in the diagnosis and initial staging of gastric cancer, showing a moderate sensitivity and specificity for the detection of lymph node metastases. 18-FDG-positron emission tomography (PET)-CT has no role in the primary detection of gastric cancer due to its low sensitivity, but better accuracy than CT in the evaluation of lymph node metastases. A key staging modality in patients with gastric cancer is staging laparoscopy, which has high accuracy in detecting occult metastases and avoids the need for laparotomies.
