Description
Summary:To analyse the incidence and survival of patients with oligometastases (solitary and normal) when they are treated in centres that are experts in multidisciplinary approach to patients with sarcoma. Retrospective analysis of 414 patients with bone metastases secondary to carcinomas at Hospital Universitario La Paz and Hospital MD Anderson Cancer Centre (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. 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. 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 centres that are experts in the treatment of sarcomas. 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 histotype of the neoplasm. Analizar la incidencia, factores pronósticos, indicación de tratamiento quirúrgico y supervivencia de los pacientes con criterios de oligometástasis óseas (solitaria y normal) tratados en centros expertos en la resección tumoral de lesiones óseas. Análisis retrospectivo de 414 pacientes afectos de metástasis óseas secundarias a carcinomas realizado en el Hospital Universitario La Paz y el Hospital MD Anderson Cancer Center (Madrid), entre mayo de 2006 y mayo de 2019. Fueron excluidas las metástasis localizadas en pelvis y esqueleto axial y se analizó a 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. 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. Los tratamientos sistémicos en el tra
