Result analysis of percutaneous core needle biopsy for bone tumors in upper limbs with pathological fracture / 中国骨伤

ABSTRACT

OBJECTIVE@#To analyze the results of percutaneous core needle biopsy for bone tumors in upper limbs with pathologic fracture and to find the possible factors that could impact the results.@*METHODS@#The including criteria for this study was the patients who had received percutaneous core needle biopsy and definitive surgery, whose tumor was located at upper limb with pathologic fracture. From January 2015 to December 2019, seventy-seven patients were enrolled. There were 55 males and 22 females. The median age was 27 years old (range5 to 88 years old). The tumor located at humerus in 67 cases, radius in 8 cases and ulna in 2 cases. If the pathologic diagnosis of core needle biopsy was the same with the definitive surgery, it was defined as "correct". If the pathologic diagnosis of biopsy for benign or malignant was right but the exact diagnostic name was not the same with definitive surgery, it was defined as "supportive". If the pathologic diagnosis of biopsy for benign or malignant was not correct, it was defined as "wrong". We retrospectively analyzed the accuracy and impact factors for core needle biopsy.@*RESULTS@#The result was "correct" in 63 cases(81.8%), "supportive" in 14 cases(18.2%), and "wrong" in 0 cases. We analyzed the gender, age, location, fracture displacement, the destroyed type for bone tumor, soft tissue mass, fluid area in the tumor as the factors. The results showed the rate for "correct" was significantly higher when the tumor had soft tissue mass (@*CONCLUSION@#The accuracy of percutaneous core needle biopsy for upper limb bone tumor with pathologic is high and acceptable. The biopsy chosen the soft tissue mass area can increase the accuracy.
