Abstract:
[Objective]To evaluate the effectiveness of biopsy of bone lesions.The factors that might effect on the clinical utility were analyzed in order to find out the independent factor for clinical effectiveness.Also we evaluated the effects of these factors on the open biopsy with needle biopsy previously done.[Method]We retrospectively reviewed 206 cases performed at our institute between June 2003 and Oct 2006,including percutaneous core-needle biopsy or open biopsy.The biopsy result was classified as correct,nondiagnostic,or incorrect.The biopsy results were considered clinical useful if they were correct and not useful if they were nondiagnostic or incorrect.We identified the independent risk factor by analyzing whether the characteristics including biopsy methods,lesion position,myxoid,lesion type reduced the effect on the clinical utility and increased the probability of proceeding to subsequent open biopsy.[Result]In 206 patients,one hundred and forty-seven cases(71.4%)underwent core-needle biopsy.Forty-seven cases(22.8%)underwent open biopsy and twelve cases(5.8%)had open biopsy with needle biopsy first.One hundred and seventy-six cases(85.4%)patients had clinical useful results.Eighteen cases(8.7%)were nondiagnostic,and twelve cases(5.8%)were incorrect.Myxoid histology was identified of independent risk factor on the clinical utility by logistic regression(P=0.02).[Conclusion]Most cases of bone lesions can be diagnosed by core-needle biopsy or open biopsy.The myxoid histology is associated with decrease clinical accuracy;No single characteristic cause increase probability of open biopsy.Correct diagnose of bone lesions requires combining biopsy,radiology and clinical data.
