Oligometastases in oncological orthopedic surgery. Our experience. / Oligometástasis en la cirugía ortopédica oncológica. Nuestra experiencia.

OBJECTIVE: To analyze the incidence and survival of patients with oligometastases (solitary and normal) when they are treated in centers that are experts in multidisciplinary approach to patients with sarcoma. MATERIAL AND METHOD: Retrospective analysis of 414 patients with bone metastases secondary to carcinomas at Hospital Universitario La Paz and Hospital MD Anderson Cancer Center (Madrid) between May 2006 and May 2019. Metastases located in the pelvis and axial skeleton were excluded, analyzing a total of 28 patients who met the criterion for solitary metastases or oligometastases with normal criteria. The study survival estimate was carried out following the Kaplan-Meier statistical method. RESULTS: The survival of the patients following the oligometastases criteria (solitary and normal) was 53%. Breast cancer was the most prevalent and had a survival rate of more than 70%. The average age of the patients was 58 years old. DISCUSSION: Systemic treatments in cancer treatment have managed to improve disease-free survival curves and lead us to redirect on the paradigm for the treatment of oligometastases, stating that treatment should be carried out in the centers that are experts in the treatment of sarcomas. CONCLUSIONS: The choice of surgical treatment for patients with oligometastases in the strict sense (solitary) and normal should be evaluated by multidisciplinary teams according to the prognoses of the patient, anatomical location and histiotype of the neoplasm.

Oligometástasis en la cirugía ortopédica oncológica. Nuestra experiencia / Oligometastases in oncological orthopedic surgery. Our experience

Objetivo: Analizar la incidencia, factores pronósticos, indicación de tratamiento quirúrgico y supervivencia de los pacientes con criterios de oligometástasis óseas con los criterios de solitaria y normal ósea tratados en centros expertos en la resección tumoral de lesiones óseas. Material y método: Análisis retrospectivo de 414 pacientes afectos de metástasis óseas secundarias a carcinomas del Hospital Universitario La Paz y Hospital MD Anderson Cancer Center (Madrid), entre mayo de 2006 y mayo de 2019. Fueron excluidos las metástasis localizadas en pelvis y esqueleto axial, analizándose un total de 28 pacientes que cumplían con el criterio de metástasis solitaria u oligometástasis con criterio normal. La estimación de la supervivencia del estudio se llevó a cabo siguiendo el método estadístico de Kaplan-Meier. Resultados: La supervivencia de los pacientes siguiendo los criterios de oligometástasis (solitaria y normal) fue del 53%. El cáncer de mama fue el más prevalente y presentó una supervivencia superior al 70%. La edad promedio de los pacientes fue de 58 años. Discusión: Los tratamientos sistémicos en el tratamiento del cáncer han conseguido mejorar las curvas de supervivencia libre de enfermedad y nos lleva a reflexionar sobre el paradigma del tratamiento de las oligometástasis, planteando que el tratamiento debería realizarse en centros expertos en la resección tumoral de lesiones óseas. Conclusiones: La elección del tratamiento quirúrgico de los pacientes afectos de oligometástasis en sentido estricto (solitaria) y normal deben ser evaluada por equipos multidisciplinarios, según el pronóstico del paciente, localización anatómica e histiotipo de la neoplasia.

Manejo con instrumentación 360 o de enfermedad ósea metastásica que condiciona inestabilidad en columna cervical. Reporte de un caso clínico / 360 degrees instrumentation for cervical instability due to metastatic bone disease. Case report

Resumen: Introducción: La columna vertebral es el sitio más frecuente de localización para las metástasis óseas; siendo los tumores de mama, próstata y pulmón los que mayor afectación presentan. La columna torácica es afectada en un 70% de los casos, seguida de la región lumbar y cervical. Material y métodos: se presenta el caso de un paciente con diagnóstico de adenocarcinoma mamario derecho, con enfermedad ósea metastásica en región cervical a nivel de C2, C3, inestabilidad del segmento cervical por fractura por compresión del cuerpo C3 de mayor al 80%, sin invasión a canal medular, inicia con parestesias de extremidades torácicas. Se realiza instrumentación 360º en dos tiempos. Posterior al procedimiento la paciente evolucionó sin dolor cervical y tolerando la vía oral. Discusión: la enfermedad ósea metastásica genera lesiones importantes en la columna vertebral condicionando inestabilidad; la instrumentación mejora el estado funcional y el pronóstico.

Abstract: Introduction: The spine is the most common site for bone metastases; being the breast, prostate and lung cancer which have most affected. The thoracic spine is involved in 70% of cases, followed by the lumbar and cervical region. Material and methods: This is a 59 years old female diagnosed with breast adenocarcinoma and metastatic bone disease in cervical spine C2, C3 level and instability of that segment because of a compression fracture of C3 greater than 80% without invasion of the spinal canal, she begins with paresthesias of upper limbs. A 360º instrumentation was performed in two stages. After the surgical procedure the patient were without neck pain and a good neurological status. Discussion: Metastatic bone disease causes significant damage to the spine sometimes create instability proper instrumentation is needed to improve the functional status and prognosis of these lesions.
