摘要
用 CT 在术前测量22例颊粘膜鳞状细胞癌患者的肿瘤厚度,与术后活检测量肿瘤厚度进行比较,其结果表明,二者之间无显著性差异(P>0.1)。CT 检测与活检测量肿瘤厚度平均值仅差0.109mm,并推算出由 CT 检测获得活检测量肿瘤厚度的直线回归方程为(?)=0.0812+0.9237X(r=0.9737,P<0.01)。CT 是一种较好的检测颊癌患者术前肿瘤厚度的方法。
This paper showed that CT scanning is useful for measuring tumor thickness of thebuecal mucosal carcinoma.In a study of 22 patients scanned prior to treatment,CT gaveadditional valuable information about the tumor thickness of primary tumors in 19 patients.The results have been compared with the measurement of clinic by rank sum test,and theauthors found there has not significant difference(P>0.1)between the two methods.Onthe other hand,the correlation coefficient of this two methods is significant(r=0.9737,P<0.01)and has linear regression equation for(?)=0.0812+0.9237X.Therefore,CT is avaluable adjunct to the detection and measurement of tumor thickness of the buccal mucosalcarcinoma.
