OBJECTIVE:The purpose of this study is to evaluate trephine biopsies with Jamshidi needle performed at the Oncologic Orthopedics Service at UNIFESP/EPM, in musculoskeletal tumors in different locations, in order to propose an effectiveness classification of biopsy categories. METHODS: A retrospective analysis was made of 107 patients that had been submitted to biopsy with the Jamshidi needle and later to a tumor resection followed by an anatomopathological exam of the surgical specimen. Mean age of the patients was 23.5 years (2.7 to 68.7 years). Regarding gender, 40.2% were female, and 50.8% male. In this series, 86 had bone tumor (80.4%) and 21 had soft tissue tumors (19.6%). With respect to location, tumors were found mainly in the lower limbs (72%), followed by upper limbs (22.4%), and pelvis (5.6%). A joint proposal was prepared to classify biopsy categories according to the excellent, good, regular, and poor result. RESULTS: General data analysis showed excellent results in 80.4% of the biopsies, good results in 8.4%, regular in 2.8%, and poor in 8.4%. Adding together excellent and good results, one has 88.8% of the cases. In the series, the authors found 3.7% of complications, and in no case the biopsy served to rule out conservative surgery with preservation of the limb. CONCLUSION: Biopsies with Jamshidi needle represented quite an efficient diagnostic method for musculoskeletal lesions, with low rate of complications and good results comparable to those of open biopsies.
