【摘要】 胃癌(gastric cancer，GC)是消化系统最常见的恶性肿瘤之一，发病率仅次于肺癌和结直肠癌。早期GC临床症状隐匿，发现时肿瘤已发展至中晚期，患者预后不佳。因此，术前预测GC淋巴结转移(lymph node metastasis，LNM)、肿瘤TNM分期及组织学分级、分化程度的区分、GC与相关肿瘤的鉴别、化疗效果及预后的评估至关重要。近年来，影像组学在GC中的应用越来越广泛。本文首先对影像组学进行介绍，然后对影像组学在GC临床中的应用进行一一叙述。

    [Abstract] Gastric cancer (GC) is one of the most common malignant tumors of the digestive system， and its incidence is second only to lung cancer and colorectal cancer. The clinical symptoms of early GC are insidious， and the tumor has developed to the middle and late stage when it is found， and the prognosis of patients is poor. Therefore， preoperative prediction of lymph node metastasis (LNM)， tumor TNM stage and histological grade， differentiation of differentiation degree， differentiation of GC and related tumors， chemotherapy efficacy and prognosis evaluation are very important.In recent years， radiomics has been widely used in GC. This paper first introduces radiomics ......
