Revised 07 January 2013
Esophagogastroduodenoscopy should be performed to identify and biopsy any suspicious intraluminal masses and to confirm whether the mass originates in the stomach or the esophagus, and if linitis plastica is present.
CT scan of the chest and abdomen/pelvis is recommended to assess the extent of local involvement and to exclude distant metastases.
For patients with early stage cT1/T2 disease, EUS may be considered to clarify cT stage and ascertain whether preoperative chemotherapy is indicated.
If no metastases are seen on baseline imaging, a laparoscopic evaluation, with peritoneal washings for cytology, for peritoneal metastases may be considered prior to surgical resection.
Recommend baseline tumour markers at diagnosis: CEA, CA 19-9.
