摘要: 准确的胃癌术前分期对选择合理的治疗方案、评估预后等具有重要的指导意义，通过精确的术前准备，可以避免不必要的治疗，选择最合理的治疗方式。近年来，胃癌的术前分期已经通过超声内镜（EUS）、多层螺旋CT（MDCT）、正电子发射计算机断层扫描（PET-CT）和分期腹腔镜等诊断手段获得了极大改善。由于各种诊断手段均存在优点与局限性，准确术前分期通常需要多种诊断模式的组合。本文就上述胃癌术前分期方法的研究进展进行综述。Abstract: Accurate preoperative staging of gastric cancer is of great significance for choosing an optimal therapeutic schedule and for evaluating the prognosis. Accurate preoperative preparation can avoid unnecessary treatment and help with selecting optimal treatment modalities. In recent years, the preoperative staging of gastric cancer has been greatly improved owing to the use of diagnostic methods such as endoscopic ultrasonography, multi-slice spiral computed tomography, positron emission computed tomography, and staging laparoscopy, among other such modalities. However, all diagnostic methods are associated with advantages and limitations. Thus, a combination of various diagnostic modalities is essential for accurate preoperative staging. This paper reviews the research progress in the aforementioned diagnostic methods for preoperative staging.
