骨軟部腫瘍の穿刺細胞診の検討

A retrospective study of 97 cases of fine needle aspiration of bone and soft part tumors performed at the National Fukuoka Central Hospital between August 1977 and September 1985 showed an overall accuracy of 74.2% in the diagnosis of malignancy. The main reason of true negative was the lack of the aspirated material and the existence of well differentiated soft part sarcomas which were judged as Papanicolaou class III. 93.9% of the cases with class IV and V were malignant. The lack of the aspirated material in the malignant tumors was noted in 10.1%. Differentiation between metastatic cancer, malignant lymphoma and sarcoma was not so difficult. Further diagnosis for histological type by the cytology depends upon the knowledge of histological details of sarcoma. We believe that cytological confirmation of malignancy by fine needle aspiration is a useful method for the treatment of malignant bone and soft part tumors.
