High-frequency sonography has become extremely helpful for the preoperative assessment of malignant melanoma. The purpose of this study was to compare the preoperative vertical tumour thickness as assessed by 7.5 MHz as well as 20 MHz ultrasound probes to the postoperative tumour thickness as determined histomorphometrically.
249 patients with malignant melanoma were studied using a conventional 7.5 MHz ultrasound machine (since 1987) or a high-frequency 20 MHz ultrasound imaging system (since 1991).
The correspondence of the sonographically assessed tumour thickness with the thickness assessed by histomorphometry was significantly better for high-frequency sonography (r = 0.94) as compared to conventional sonography (r = 0.76). For stages pT3 and pT4, however, this difference was not significant.
Based on these data, high-frequency sonography should be given preference in the preoperative assessment of malignant melanoma over conventional 7.5 MHz ultrasound. However, for stages pT3 and pT4 both methods offer similarly reliable results.
高频超声检查对恶性黑色素瘤的术前评估极为有用。本研究的目的是比较用7.5兆赫以及20兆赫超声探头评估的术前肿瘤垂直厚度与组织形态测量法测定的术后肿瘤厚度。
对249例恶性黑色素瘤患者使用传统的7.5兆赫超声仪（自1987年起）或高频20兆赫超声成像系统（自1991年起）进行研究。
与传统超声检查（r = 0.76）相比，高频超声检查在超声评估的肿瘤厚度与组织形态测量法评估的厚度之间的对应性显著更好（r = 0.94）。然而，对于pT3和pT4期，这种差异并不显著。
基于这些数据，在恶性黑色素瘤的术前评估中，高频超声检查应优先于传统的7.5兆赫超声检查。然而，对于pT3和pT4期，两种方法都能提供同样可靠的结果。
