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。
The thickness of tumors in 22 patients with buccal mucosal squamous cell carcinoma was measured preoperatively by CT and compared with the thickness of tumors after live detection. The results showed that there was no significant difference between the two (P>0.1). The mean value of the tumor thickness measured by CT and the amount of live detection was only 0.109 mm, and the linear regression equation for the tumor thickness measured by CT was calculated as (?)=0.0812+0.9237X (r=0.9737, P<0.01). CT is a good method to detect the thickness of preoperative tumor in patients with buccal cancer.
