Resumen
Introducción: los tumores óseos malignos primarios son raros, pero tienen una alta mortalidad global. El osteosarcoma y el condrosarcoma son los sarcomas óseos más comunes en la pelvis. El manejo quirúrgico de los tumores óseos primarios en la pelvis es desafiante y depende de varios factores. La hemipelvectomía interna con preservación de la extremidad se ha vuelto más popular en comparación con la hemipelvectomía externa.
Objetivo: identificar y describir características del manejo quirúrgico de tumores óseos y tejidos blandos de pelvis mediante hemipelvectomía.
Material y métodos: estudio observacional de casos consecutivos, en el que se identificaron pacientes con tumores óseos y tejidos blandos sometidos a hemipelvectomía en período de enero del 2010 a diciembre del 2020 en el Servicio de Cirugía Oncología, utilizando la escala MSTS (Musculoskeletal Tumor Society).
Resultados: se incluyeron 17 pacientes con tumores pélvicos, 10 (58.8%) sarcomas óseos primarios, 3 (17.6%) sarcomas de tejido blando, 3 (17.6%) tumores óseos benignos, 1 (5.8%) neoplasia de origen hematológico. Seguimiento promedio de 30 ± 14. La complicación quirúrgica más frecuente fue el seroma de herida quirúrgica, presente en 6 pacientes (37.5%).
Conclusiones: se requiere equipo multidisciplinario para individualizar tratamiento con la mejor secuencia de opciones, dando mejoría de resultado oncológico y funcional.
Abstract
Background: Primary malignant bone tumors are rare however, have a high global mortality rate. Osteosarcoma and chondrosarcoma are the most common bone sarcomas in the pelvis. The surgical management of primary bone tumors in the pelvis is challenging and depends on several factors. Internal hemipelvectomy with extremity preservation has become more popular compared to external hemipelectomy.
Objective: Identify and describe characteristics of the surgical management of bone tumors and soft tissues of the pelvis by means of hemipelvectomy.
Material and methods: Observational study of consecutive cases, in which patients with bone and soft tissue tumors undergoing hemipelvectomy were identified from January 2010 to December 2020 at the Oncology Surgery Department, using the Musculoskeletal Tumor Society (MSTS) scale.
Results: 17 patients with pelvic tumors were included, 10 (58.8%) primary bone sarcomas, 3 (17.6%) soft tissue sarcomas, 3 (17.6%) benign bone tumors, 1 (5.8%) neoplasia of hematological origin. Average follow-up of 30 ± 14. Most frequent surgical complication, surgical wound seroma, 6 patients (37.5%).
Conclusions: A multidisciplinary team is required to individualize treatment with the best sequence of options, giving improvement in oncological and functional results.
