彩色多谱勒血流显像对胃癌术前分期的价值

目的]评价彩色多谱勒血流显像（以下简称CDFI）对胃癌术前分期的应用价值。方法]应用彩色多谱勒对97例胃癌病人超声检查并行手术治疗，将术前分期与术后病理结果进行分析。结果]经CDFI术前分期的病例手术切除率为91.8%，胃癌浸润胃壁的深度（T）符合率T1,T2,T3,T4分别为75.0%(9/12),61.3%(19/31),85.3%(29/34),85.0%(17/20)。区域淋巴结（N）检出率为78.4%，对盆腔和肝转移的检出率分别为25.0%和90.9%。结论]彩超对胃癌术前分期有较高的准确性，对治疗决策的制定有指导价值。

The Clinical Value of Color Doppler Flow Imaging in Preoperative Staging for Gastric Cancer

To evaluate the color doppler flow imaging (CDFI) in preoperative staging of gastric cancer.Ninety-seven cases with gastric cancer were examined with CDFI and operated.Comparision was made between CDFI and pathological results after operation.The rate of surgical resection was 91.8%. The accuracy of CDFI for depth of invasion(T category) was 75.0%,61.3%,85.3%,85.0% in T1,T2,T3,T4 respectively.The accuracy of CDFI for nodal staging (N category) was 78.4%,the accuracy of CDFI for cancer remove to the pelvic and the liver was 25.0% and 90.9%.Conclusion]The CDFI examination can provide high accuracy in the preoperative staging of gastric cancer,the result may influence the decision-making and the therapy.
