Figure 1 Preoperative evaluations (Case 1)(A) Endoscopic examination showed a large ulcerofungating mass in the gastric cardia. (B, C) Contrast-enhanced CT demonstrated a 13.6-cm exophytic gastric tumor with suspected invasion into the pancreas and transverse colon. Brown arrow: collapsed splenic flexure of transverse colon due to abutment of the large gastric tumor. Yellow arrow: laterally displaced pancreas due to abutment by the large gastric tumor. (D) PET imaging revealed a huge hypermetabolic gastric tumor with a nodule suggestive of pelvic seeding. Green arrow: hypermetabolic lesion suggestive of a pelvic seeding nodule.
