目的探讨螺旋CT三期扫描对胃癌术前分期的诊断价值。方法选择2010年1月—2012年6月兴义市人民医院CT室收治的61例经临床诊断为胃癌的患者,对其进行术前螺旋CT三期扫描,并应用TNM分期系统对患者实际情况做病理分期,与扫描的结果相比较分析,进而确定其诊断价值。结果螺旋CT三期扫描对胃癌病灶的检出率为100%,TNM分期中,T分期中有45例患者的分期与临床病理分期符合,符合率为73.8%;N分期中有33例患者的分期与临床病理分期相符合,符合率为54.1%;M分期中有56例的患者的分期与临床病理分期符合,符合率为91.8%。螺旋CT扫描与病理检查TNM分期中T期比较,差异无统计学意义(P>0.05)。N分期中螺旋CT扫描结果在N0、N1、N2期与病理检查结果比较,差异均有统计学意义(P<0.05)。M分期中螺旋CT扫描结果与病理检查结果比较,差异无统计学意义(P>0.05)。结论螺旋CT三期扫描的结果与病理结果有较高的相符度,尤其是T分期与M分期,对临床诊断有很重要的指导作用.
Objective To investigate the value of three-phase spiral CT in the diagnosis of gastric cancer preoperative staging. Methods Sixty-one patients with clinically diagnosed gastric cancer admitted to Xingyi People’s Hospital from January 2010 to June 2012 were enrolled in the study. Three-phase preoperative spiral CT was performed and TNM staging system was used to evaluate the actual situation of patients Pathological staging, compared with the results of the scan, and then determine the diagnostic value. Results The detection rate of gastric cancer by three-phase spiral CT scan was 100%. The staging of 45 patients in T stage was consistent with the clinicopathological stage in TNM staging, the coincidence rate was 73.8%; in 33 cases of N staging Staging was consistent with clinicopathological staging, with a coincidence rate of 54.1%. Staging of 56 patients in M staging was consistent with clinicopathologic staging, with a coincidence rate of 91.8%. Spiral CT scan and pathological TNM staging in T phase, the difference was not statistically significant (P> 0.05). N stage staging spiral CT scan results in the N0, N1, N2 and pathological examination results, the difference was statistically significant (P <0.05). M staging spiral CT scan results and pathological examination results, the difference was not statistically significant (P> 0.05). Conclusion The results of three-phase spiral CT scan and pathological results have a high degree of compliance, especially the T stage and M stage, clinical diagnosis has an important guiding role.
