目的 探究螺旋CT增强扫描对进 展期胃癌的淋巴结转移的应用价值研究。 方法 选取我院2013年6月-2016年6月通过 胃镜确诊并且经过手术病理证实的进展期 的胃癌62例，采用CT仪器为飞利浦公司的 多排螺旋CT(MSCT)进行增强扫描，对患者 的胃附近的淋巴结的形态类型影像图像、 短径实行观察，在和手术后的病理结果进 行对比，进而对进展期胃癌旁胃周的淋巴 结转移分析，确定相关的生物学行为因 素。结果 短径5mm组与组间的P<0.05，从 而推理出5mm组短径与组间存在统计学差 异，短径15mm组和短径组间P>0.05，所以 可以推断出不存在统计学差异，以此说明 了短径9mm成为螺旋CT增强扫描分析诊断 胃周淋巴结转移具有统计学意义。多类胃 癌生物学行为CT影像特征与癌肿对应淋巴 结转移率密切相关(P<0.05)。结论 胃癌 的术前分期和临床治疗使用多层螺旋CT具 有一定的指导意义和临床价值。

Objective To investigate the application value study of spiral ct enhanced scanning on lymph node metastasis of progressive stage gastric carcinoma. Methods 62 cases with advanced gastric cancer confirmed by gastroscope diagnosis in our hospital from June 2014 to June 2016 were selected. They were given MSCT enhanced scanning for observing morphotype and diameter of lymph nodes nearby stomach. Compared with postoperative pathologic results and then determine the relative biology behavior factors of lymph node metastasis of progressive stage gastric carcinoma. Results Diameter of 5mm group, the difference was statistically significant (P<0.05). Diameter of 15mm group, the difference was not statistically significant (P>0.05). It showed that 9mm was standard for diagnosing lymph node metastasis nearby gastric cancer. Multiple gastric cancer biology applied CT and lymph node metastasis had intimate connections. Conclusion Application of MSCT in preoperative staging and clinic treatment of gastric carcinoma has certain guiding significance.
