目的：探讨针吸细胞学在骨恶性肿瘤诊断中的应用价值。方法：在X线平片协助定位条件下，对41例骨恶性肿瘤采用针吸细胞学检查，其中20例作了病理组织学对照。结果：针吸细胞学诊断与病理组织学诊断比较，阳性准确率为100％，无一例假阳性；细胞学分类与病理学分类比较，分类准确率为85％。说明用针吸细胞学诊断骨肿瘤简便、快速，临床效果满意。结论：针吸细胞学诊断骨恶性肿瘤有一定临床应用价值，但在针吸细胞学检查过程中，应做到细胞学、临床、X线平片三结合。
Objective: To explore the value of needle aspiration cytology in the diagnosis of bone malignant tumors. METHODS: A needle-suction cytology test was performed on 41 cases of bone malignancies under the condition of X-ray plain film-assisted localization. Among them, 20 cases were compared with pathological histology. RESULTS: Compared with the histological diagnosis of needle aspiration cytology, the positive rate was 100%, and there was no false positive. The accuracy of classification was 85% compared with cytological classification and pathological classification. It shows that the use of needle aspiration cytology to diagnose bone tumors is simple, rapid and satisfactory. Conclusion: Needle aspiration cytology has a certain clinical application value in diagnosing malignant bone tumors, but in the process of needle aspiration cytology, cytology, clinical and X-ray plain film should be combined.
