摘　　要：目的分析术前CT检查对于胃癌T分期诊断的临床价值研究。方法我院从2014年6月至2016年6月选取收治胃癌患者70例,经有经验的医生对其进行T分期,与手术后病理结果进行比较。结果 70例病患经过手术的胃癌病患CT术前诊断和术中检查确认结果完全一样,准确度为100%。病灶在胃底贲门的有12例,在胃窦部位置的为40例,在胃体部为18例。T1分期准确率为(9/12)75.0%,T2期为(11/18)61.1%,T3期为(30/35)85.7%,T4期为60.0%(3/5),总T分期的准确率是70.6%,Kappa检验值为0.64,表明与病理分析的结果一致性较好。结论 CT对胃癌诊断率精确,具有一定的优越性,可以提高胃癌术前T分析诊断的准确性,是手术前分期的可行方法,对胃癌的治疗具有指导意义,应用价值高,值得在临床推广使用。Objective To study the clinical value of preoperative CT examination in T staging diagnosis of gastric cancer.Methods From June 2014 to June 2016, 70 patients with gastric cancer were enrolled in our hospital. T- staging was performed by experienced physicians. The results were compared with those of postoperative pathology. Results The lesion of all patients showed that preoperative diagnosis and intraoperative examination exactly the same for the 70 patients with gastric cancer underwent surgery, the accuracy was 100%. Lesions in the bottom of the cardia in 12 cases, 40 patients in the antrum position, 18 patients with gastric body disease. The accuracy of T1 stage was （9/12） 75.0%, T2 stage was （11/18） 61.1%, T3 stage was （30/35） 85. 7%, T4 stage was 50.0% （3/5）. The total accuracy rate was 75.7%, Value of Kappa test was 0.64, indicating that it has good agreement with the results of pathological analysis.Conclnsions CT is an accurate method for the diagnosis of gastric cancer. It can improve the accuracy of preoperative T-diagnosis of gastric cancer. It is a feasible method for staging of gastric cancer. It has a guiding significance for the treatment of gastric cancer, is worthy of clinical use.
