Fifty consecutive patients with gastric adenocarcinoma proved by means of biopsy underwent preoperative staging with endoscopic ultrasonography (US). Dynamic computed tomography (CT) of the chest and abdomen was performed before surgery in 33 of the patients. In all 50 patients, the TNM classification of the American Joint Committee on Cancer was used to compare the imaging findings with pathologic findings in specimens resected at surgery. When the depth of tumor penetration was evaluated, the findings at endoscopic US and those at pathologic examination were concordant in 46 of 50 patients (92%), and the findings at dynamic CT and those at pathologic examination, in 14 of 33 patients (42%) (P less than .00042). Evaluation of regional lymph node metastases showed a concordance of 78% with endoscopic US and 48% with dynamic CT (P less than .038). Overall determination of stage with both dynamic CT and endoscopic US showed a concordance of 73%, compared with a concordance of 45% for dynamic CT alone (P less than .028).
50例经活检证实为胃腺癌的患者接受了术前内镜超声（US）分期。其中33例患者在手术前行胸部和腹部动态计算机断层扫描（CT）。对所有50例患者，采用美国癌症联合委员会的TNM分类法，将影像学检查结果与手术切除标本的病理检查结果进行比较。评估肿瘤浸润深度时，50例患者中有46例（92%）内镜超声检查结果与病理检查结果一致，33例患者中有14例（42%）动态CT检查结果与病理检查结果一致（P<0.00042）。区域淋巴结转移评估显示，内镜超声检查的符合率为78%，动态CT检查的符合率为48%（P<0.038）。动态CT和内镜超声联合进行的总体分期判定符合率为73%，而单独动态CT的符合率为45%（P<0.028）。
