[Surgical management of pelvic tumors through hemipelvectomy].

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.
