Answer

Studies for staging of stomach cancer may include the following [4] :

  • Upper gastrointestinal (GI) tract endoscopy and biopsy
  • Chest/abdomen/pelvic computed tomography (CT) with oral and intravenous contrast
  • Positron emission tomography (PET) – CT evaluation if no evidence of M1 disease is found, and if clinically indicated
  • Complete blood cell count (CBC) and comprehensive chemistry profile
  • Endoscopic ultrasound if no evidence of M1 disease is found
  • Endoscopic resection for early-stage cancers
  • Biopsy of metastatic disease as clinically indicated
  • HER2-neu testing if metastatic adenocarcinoma is documented or suspected
