目的:分析进展期胃癌的CT表现,提高CT对进展期胃癌的认识。方法:搜集近两年来我院经手术及病理证实的45例进展期胃癌,对其CT表现作回顾性分析,讨论其CT表现特点。结果:45例进展期胃癌中其CT的影像学特点表现为胃壁增厚、软组织肿块、溃疡、环堤、胃腔狭窄、腹腔内淋巴结转移等、其中BorrmannⅠ型(蕈伞型癌)5例(11%)、BorrmannⅡ型(局限溃疡型癌)8例(18%)、BorrmannⅢ型(浸润溃疡型癌)17例(38%)、BorrmannⅣ型(浸润型癌)15例(33%)。结论:CT能很好显示进展期胃癌特征,并能明确诊断,能清晰显示胃癌向周围组织侵犯及腹腔内转移情况,对临床治疗有指导作用。
Objective: To analyze the CT features of advanced gastric cancer and improve the understanding of advanced gastric cancer by CT. Methods: Forty-five cases of advanced gastric cancer confirmed by surgery and pathology in our hospital during the past two years were collected. The CT features of the patients were retrospectively analyzed and their CT features were discussed. Results: The imaging features of CT in 45 cases of advanced gastric cancer were thickening of gastric wall, soft tissue mass, ulcer, embankment, stenosis of stomach cavity, lymph node metastasis of abdominal cavity, etc. Among them, there were 5 cases of Borrmann type I (parasaphragm-type carcinoma). 11%), Borrmann type II (localized ulcerated carcinoma) 8 cases (18%), Borrmann type III (infiltrated ulcer type carcinoma) 17 cases (38%), Borrmann type IV (invasive carcinoma) 15 cases (33%). Conclusion: CT can well show the characteristics of advanced gastric cancer, and can confirm the diagnosis. It can clearly show the invasion of gastric cancer into the surrounding tissue and the intra-abdominal metastasis, and it has a guiding effect on clinical treatment.
