The effect of biopsy on survival of patients with osteosarcoma

19,6%). Quanto à localização, os tumores encontravam-se preferencialmente nos membros inferiores (72%), seguidos dos membros superiores (22,4%) e pelve (5,6%). Foi proposta conjuntamente uma classificação para categorizar as bióp-sias conforme o seu resultado em excelente, bom, regular e mau. Resultados: A análise dos dados gerais demonstrou resultados excelentes em 80,4% das biópsias, bons em 8,4%, regulares em 2,8% e ruins em 8,4%. Somando-se os resultados excelentes e bons, encontram-se 88,8% dos casos. Nos casos avaliados, encontraram-se 3,7% de complicações; em nenhum caso a biópsia contra-indicou a cirurgia conservadora -com preservação do membro. Conclusão: As biópsias com agulha de Jamshidi representam método bastante eficiente de diagnóstico das lesões músculo-esqueléticas, com baixo índice de complicações e bons resultados compará-veis aos das biópsias abertas.Descritores -Osteossarcoma; Oncologia / classificação; Biópsia por agulha; Estudos retrospectivos RESUMOObjetivo: O propósito deste estudo foi aquilatar a precisão das biópsias por trefina de Jamshidi, realizadas no Serviço de Ortopedia Oncológica da UNIFESP / EPM, em tumores músculo-esqueléticos, em distintas topografias, tendo como objetivo propor uma classificação para categorizar as biópsias

Osteosarcoma is a malignant mesenchymal tumour. This primarily manifests in the formation of immature osteoid cells by tumour cells. Osteosarcoma is the most common primary bone tumour in children and adolescents. It tends to occur in the metaphysis of long shafts, shows osteoblastic differentiation, and produces malignant osteoid material. We present the case of a 17-year-old male who presented to our clinic who had left knee pain for a few days. An initial radiograph of the knee joint revealed a lytic lesion in the proximal tibia and further imaging was advised. During a follow-up visit, the patient had worsening pain and had a computerized tomography scan of the left knee, confirming osteosarcoma on the lateral side of the left tibia. He was referred to the orthopaedic department, where a biopsy was performed, to confirm the diagnosis of osteosarcoma. The patient was commenced on chemotherapy due to metastatic disease and has so far tolerated therapy well.

During the past several years, the indications for limb salvage in musculoskeletal neoplasms have been expanded. As a result, interest in the topic of diagnostic biopsy has been renewed. Post biopsy hematoma formation and the iatrogenic spread of cancer cells has led to universally accepted guidelines for biopsy technique. These include meticulous hemostasis and wound closure. A technique of open biopsy without wound closure in which the biopsy site in a long bone with contained neoplasm remains open and hematoma allowed to drain into the dressings is outlined. A discussion of the theoretical advantages and disadvantages of this technique is presented.
