A 50-year-old man with gastric cancer pathologically diagnosed with serosal invasion. a The endoscopic image indicates a mass lesion in the posterior wall of the stomach body. b Hematoxylin and eosin (H&E) staining of a specimen based on endoscopic biopsy shows a poorly differentiated carcinoma (original magnification, × 100). c The values of the tumor markers, including AFP, CEA, CA125, CA199, CA724, and CA242, were 3.40 ng/mL, 0.70 ng/mL, 5.90 U/mL, 9.91 U/mL, 0.90 U/mL, and 4.05 U/mL, respectively. d The late arterial phase computed tomography (CT) image shows a mass lesion with marked enhancement in the posterior wall of the stomach body. An oval region of interest (ROI) was drawn to encompass the area of greatest enhancement on the maximal section, and the CT value-related parameters were extracted. e A polygonal ROI was manually drawn along the margin of the tumor on the largest cross-section, and the texture parameters were extracted. f H&E staining of a postoperative specimen confirms gastric cancer with serosal invasion (original magnification, × 20). AFP, alpha fetoprotein; CEA, carcinoembryonic antigen; CA, carbohydrate antigen
