In this retrospective study, the authors compared the sensitivity and specificity, in terms of the diagnosis of malignancy, of two techniques of ultrasound-guided biopsy of liver tumours. The first technique involving fine needle biopsy with cytological and histological analysis of the specimen was carried out in 39 patients. A technique using a wide calibre needle with frozen section examination of the fragment obtained was performed in 27 patients. All patients had one or more malignant liver tumours. Sensitivity and specificity of the technique with frozen section histology were both 100 per cent, while figures for the technique with delayed histological study were 84.6 and 87.4 per cent. This study suggests that frozen section histology might be associated with greater sensitivity than delayed histology.
在这项回顾性研究中，作者比较了两种肝脏肿瘤超声引导活检技术在恶性肿瘤诊断方面的敏感性和特异性。第一种技术是对39例患者进行细针活检，并对标本进行细胞学和组织学分析。第二种技术是对27例患者使用粗针，并对获取的组织块进行冰冻切片检查。所有患者均有一个或多个肝脏恶性肿瘤。冰冻切片组织学技术的敏感性和特异性均为100%，而延迟组织学研究技术的敏感性和特异性分别为84.6%和87.4%。这项研究表明，冰冻切片组织学可能比延迟组织学具有更高的敏感性。
