摘　　要：目的:研究CT纹理分析参数(均值、峰度、熵、短径)异常与直肠癌预后情况的相关性。方法:选取我院2019年2月至2021年3月收治的直肠癌患者80例,根据其术后1年随访结果分为预后良好组(37例)和预后不良组(43例),所有患者术前行多层螺旋电子计算机断层扫描(MSCT),对比分析2组患者相关CT纹理参数(均值、峰度、熵、短径),分析各参数与直肠癌预后情况之间的关系。结果:预后良好组患者的峰度、熵、短径纹理参数明显小于预后不良组(P<0.05),2组患者均值比较差异无统计学意义(P>0.05)。使用ROC曲线图对MSCT纹理分析参数对直肠癌预后情况预测价值分析结果显示,均值、峰度、熵、短径四个CT纹理参数中,峰度、熵、短径对直肠癌预后良好的预测灵敏度分别为62.8%、72.1%和83.7%,特异度分别为81.1%、83.8%和86.5%,三者中短径的预测价值最高(AUC=0.865),均值对直肠癌预后预测诊断价值不高(P>0.05)。结论:CT纹理图像参数中的峰度、熵、短径对直肠癌预后情况具备较高的预测诊断价值,其中短径的灵敏度、特异度最高。Objective To explore the relativity of abnormal parameters from CT striation analysis(averaged values,peak degree,entropy,short-diameter)with the prognosis of rectal cancer.Methods Enrolled 80 patients with rectal cancer treated in authors’hospital(2019-02-2021-03),according to the postoperative 1-year follow-up’s results divided them into better prognosis group(37 cases)and bad prognosis group(43 cases),which both all received preoperative MSCT inspection,then,analysed both’s relevant CT striation parameters,i.e averaged values,peak degree,entropy,and short-diameter,further explored the relation of these parameters to prognosis of rectal cancer.Results Between the two groups in averaged values there was no statistical difference(P>0.05),but in rest three parameters better prognosis group was all significantly smaller than bad prognosis group(P<0.05);ROC analysis results showed on the parameters’predictive value in the prognosis of rectal cancer showed excepting for the averaged values having not higher predictive diagnosis values(P>0.05),the predictive sensitivity of peak degree,entropy,and short-diameter was respectively 62.8%,72.1%and 83.7%,meanwhile,the specificity,was 81.1%,83.8%,and 86.5%,thus short-diameter’s predictive value was the most(AUC=0.865).Conclusion For the prognosis of rectal cancer peak degree,entropy and short-diameter have higher predictive diagnosis value,in which short-diameter’s sensitivity and specificity is the most.
