摘要
用B超检测22例颊癌患者肿瘤厚度探讨另一种术前检测肿瘤厚度的手段。结果发现,B 超检测与临床大体标本检测的肿瘤厚度之间无显著性差异(P>0.1)。这两种检测方法之间有相关关系(r=0.8529,P<0.01),其直线回归方程为:(?)=0.2533+0.7623X。将 CT 检测与 B 超检测肿瘤厚度作对比研究发现,CT 较 B 超更为准确,但 B 超具有操作简单、价廉、可重复等优点,可弥补 CT 检测的不足。
The authors have scanned 25 patients with the carcinoma of buccal mucosa by B-ultr-asound.In all cases appeared nonhomogenous solid low echo areas,which have measuredtumor thickness in pre-operation with the clinical results in post-operation were analyzedby rank sum test.The results demonstrated that there has not significant,difference(P>0.1)between the measurement of ultrasound and the measurement of clinic.And the correlationof this two methods is significant(r=0.8529,P<O.O1),it has linear regression equationfor(?)=0.2533+0.7623X.B-ulirasounic investigation has advantage of being simple andnon-invasive.It provides valuable data for clinical diagnosis and it is useful for measurementof tumor thickness of the buccal muosal carcinoma.
