202例骨肉瘤针吸细胞学特点

Characteristics of fine needle aspiration cytology in 202 cases of osteosarcoma

目的通过术前用针吸细胞学诊断202例骨肉瘤为临床诊断、治疗提供有力依据。方法用50ml干燥注射器，8至9号针头，常规消毒后快速进针到达肿瘤实质部位，抽拉针芯保持一定负压抽吸，将抽吸物直接涂片自然干燥，瑞特染色，光学显微镜观察。结果258例恶性骨肿瘤中，细胞学诊断骨肉瘤202例，168例有病理组织学对照，针吸细胞学诊断与病理组织切片对照符合率为82％，骨其它恶性肿瘤56例。结论提出针吸细胞学诊断骨肉瘤的可行性，细胞学诊断及鉴别诊断的要点，针吸细胞学是诊断骨肉瘤的一种简便、易行、快速、安全的方法。

Objective To provide a valuable gist for clinical diagnosis and treatiment of osteosarcoma by preoprative fine needle aspiration cytology. Method Sterilized 50 ml dry syringe with 8~9 gauge needle was used for the aspiration of the tumor parenchyma , a smear was made, stained with Wright stain and observed under a microscope. The essential points. of the cytological diagnosis and differential diagnosis of the lesion were discussed. Results In the 258 cases with malignant osteoma, there were 202 cases with osteosarcoma and 168 cases had pathological examinations . The consistent rate between the diagnosis of fine needle aspiration cytology and pathology was 82%. There were 56 cases with other malignant tumors. Conclusion It is feasible to use needle aspiration cytology for the diagnosis of osteosarcoma , and it is a simple , rapid and safe method.
