• To investigate the value of transabdominal ultrasonography (TAUS) in preoperative assessment of TNM stage and tumor angiogenesis for patients with gastric carcinoma. Sixty- four patients with gastric carcinoma preoperatively underwent TAUS, in whom transabdominal color Doppler ultrasonography was used for measuring color Doppler vascularity index (CDVI) of each tumor in 37 cases and microvessel density (MVD) was evaluated by using immunohistochemical staining of surgical specimens with anti- CD34 antibody. The overall accuracy rate was 56.0% for T staging of gastric carcinoma (T (1) 2/3 cases, T (2) 28.6% , T (3) 73.1% , T (4) 50.0% , respectively) by TAUS. The diagnostic accuracy rate was 63.3% for lymph node status of gastric carcinoma. The diagnostic sensitivity and specificity for lymph node metastasis was 37.9% and 100% respectively. The overall accuracy for N staging of gastric carcinoma was 57.1% (N (0) 100% , N (1) 16.7% , N (2) 35.3% , respectively). The diagnostic sensitivity and specificity for det
