Summary
Internal hemipelvectomy for pelvic tumors showed significant mortality, with 9 of 13 patients dying from cancer. Survivors experienced long-term follow-up, indicating potential for disease control in some cases.
Area of Science:
- Orthopedic Oncology
- Surgical Oncology
- Pelvic Tumor Management
Background:
- Primary malignant tumors of the pelvis are rare but aggressive.
- Internal hemipelvectomy is a complex surgical procedure for tumor resection.
- Reconstruction methods following hemipelvectomy vary and impact outcomes.
Purpose of the Study:
- To evaluate the outcomes of internal hemipelvectomy for primary malignant pelvic tumors.
- To assess survival rates and functional results after various reconstruction techniques.
- To analyze the impact of tumor type on prognosis.
Main Methods:
- Retrospective review of 13 patients with primary malignant pelvic tumors.
- Surgical procedure: internal hemipelvectomy without megaprostheses or massive allografts.
- Reconstruction methods included resection only, strut grafts, autoclaved autograft, and ilio-femoral arthrodesis.
Main Results:
- Nine out of 13 patients died from their disease within an average of 23 months.
- Four patients survived, with 3 being disease-free at an average follow-up of 84 months.
- Tumor types included Ewing's sarcoma, osteosarcoma, chondrosarcoma, and malignant fibrous histiocytoma.
Conclusions:
- Internal hemipelvectomy for primary pelvic malignancies is associated with high mortality.
- While challenging, limb-sparing surgery with various reconstruction techniques can achieve long-term survival in a subset of patients.
- Further research into optimizing reconstruction and adjuvant therapies is warranted.
