Abstract
As metástases ósseas que acometem o segmento torácico e lombar da coluna vertrebal têm como principais complicações o fenômeno doloroso e a compressão medular ou radicular. O tratamento adotado dependerá das condições clínicas e neurológicas do paciente e do grau de invasão tumoral. Foram analisados, prospectivamente, 32 pacientes acometidos por metástases do segmento torácico e lombar da coluna vertebral, sendo tratados com cirurgia de descompressão e estabilização interna seguida por radioterapia ou irradiação com mobilização externa. A seleção dos grupos foi estabelecida de acordo com a sensibilidade do tumor a radioterapia, condições clínicas, grau de estabilidade da coluna, grau de compressão medular/radicular e opção do paciente. A escala de Frankel e o teste visual de dor foram aplicados no momento do diagnóstico e após 1 e 6 meses. O grupo cirúrgico apresentou melhores resultados, mantendo a deambulação por mais tempo, pois manteve a força muscular nos pacientes Frankel E, propiciou a reversão do déficit neurológico pré-operatório em 61,5% dos casos e propiciou melhora significativa da dor.
Bone metastases at the thoracic and lumbar segment of the spine are usually presented with painful sensation and medullar compression. The treatment is based on the clinical and neurological conditions of the patient and the degree of tumor invasion. In the present study, 32 patients with spinal metastasis of thoracic and lumbar segment were prospectively analyzed. These patients were treated by decompression and internal stabilization followed by radiotherapy or irradiation with external immobilization. The election of the groups was in accordance with the tumor radiotherapy sensitivity, clinical conditions, spinal stability, medullar or nerve compression and patient's decision. The Frankel scale and pain visual test were applied at the moment of diagnosis and after 1 and 6 months. The surgical group had better results with preserving the ambulation longer and significant reduction of pain.
