摘要
胃癌术前TNM分期对制定治疗方案、评价预后具有重要意义。第8版胃癌TNM分期系统的实施为胃癌影像检查的临床实践及研究方向提供了新的依据和指导。在该版分期中超声内镜、增强CT的价值得到了充分肯定;而双能量CT、扩散加权成像(DWI)、PET/CT等技术作为当前胃癌影像研究热点,有望进一步提高胃癌术前分期的准确性。结合第8版分期系统,就超声、CT、MRI及PET/CT等影像检查手段对于胃癌术前c TN分期的研究进展予以综述。
Preoperative TNM staging of gastric cancer is of great significance for designing treatment plans and estimation of prognosis.The eighth edition of TNM staging system for gastric cancer provides a new basis and guidance for the clinical practice and research direction of gastric cancer imaging.The value of endoscopic ultrasonography(EUS)and enhanced CT was fully affirmed in this edition.Dual-energy CT,diffusion-weighted imaging(DWI),PET/CT and other technologies,as the current research hotspot of gastric cancer imaging,are expected to further improve the accuracy of preoperative staging of gastric cancer.Combined with the eighth edition staging system,the research progress of preoperative cTN staging of gastric cancer was reviewed in the fields of US,CT,MRI and PET/CT.
