进展期胃癌患者于外科手术治疗前行腹部CT检查可了解肿瘤向胃周围扩散的程度,对一些手术不能切除的胃癌可避免不必要的剖腹探查术。然而,CT在胃癌分期中的应用价值尚有争议。本研究对进展期胃癌患者术前腹部CT检查与外科手术所见进行对比分析,以探讨腹部CT在评价胃癌扩散中的作用。 56例进展期胃癌患者均接受腹部CT检查及外科手术治疗。所有病例均经放射学、内镜、手术和病理组织学检查证实为胃腺癌伴淋巴结转移,其中男36例,女20例,平均年龄66岁。 在腹部增强CT扫描后,所有CT片均由同一位放射专家进行分析,对肿瘤的胃外扩散进行评估。若在胃
In patients with advanced gastric cancer undergoing abdominal CT examination before surgical treatment, the extent of tumor spread around the stomach can be understood, and unnecessary laparotomy can be avoided for some surgically unresectable gastric cancers. However, the value of CT in the staging of gastric cancer is controversial. The purpose of this study was to compare preoperative abdominal CT and surgical findings in patients with advanced gastric cancer to investigate the role of abdominal CT in the evaluation of gastric cancer spread. 56 patients with advanced gastric cancer received abdominal CT examination and surgical treatment. All cases were confirmed by radiology, endoscopy, surgery and histopathological examination for gastric adenocarcinoma with lymph node metastasis, including 36 males and 20 females with an average age of 66 years. After abdomen-enhanced CT scans, all CT scans were analyzed by the same radiologist and evaluated for extravasated gastric tumors. If in the stomach
