Do Surgical Margins Affect Local Recurrence and Survival in Extremity, Nonmetastatic, High-grade Osteosarcoma?
Long-term survival for all patients with osteosarcoma using current aggressive adjuvant chemotherapy and surgical resection is between 60% and 70%. In patients who present with nonmetastatic, high-grade extremity osteosarcoma of bone, limb salvage surgery is favored, when appropriate, over amputation to preserve the limb, because limb salvage may lead to a superior quality of life compared with amputation. However, concern remains that in the attempt to preserve the limb, close or microscopically positive surgical margins may have an adverse effect on event-free survival.
Are Complications Associated With the Repiphysis® Expandable Distal Femoral Prosthesis Acceptable for Its Continued Use?
Reconstruction of the distal femur after resection for malignant bone tumors in skeletally immature children is challenging. The use of megaprostheses has become increasingly popular in this patient group since the introduction of custom-made, expandable devices that do not require surgery for lengthening, such as the RepiphysisLimb Salvage System. Early reports on the device were positive but more recently, a high complication rate and associated bone loss have been reported.
What Are the Risk Factors and Management Options for Infection After Reconstruction With Massive Bone Allografts?
Massive bone allografts have been used for limb salvage of bone tumor resections as an alternative to endoprosthesis, although they have different outcomes and risks. The use of massive bone allografts has been thought to be associated with a high risk for infection, and there is no general consensus on the management of this complication and final outcome. Because infection is such a devastating complication of limb salvage, at times leading to loss of a limb, recognizing the risk factors for infection and the results of treatment is important.
Is Radiation Necessary for Treatment of Non-Hodgkin’s Lymphoma of Bone? Clinical Results With Contemporary Therapy
Non-Hodgkin’s lymphoma (NHL) of bone is a rare musculoskeletal malignancy accounting for fewer than 7% of bone cancers. Traditionally, we have treated patients who have NHL of bone with chemotherapy and radiation therapy, but the role of radiotherapy in disease management and patient functional outcomes after treatment have not been well studied. We investigated the survival advantage of radiotherapy in a large cohort of patients with NHL of bone and assessed associated patient complications of radiotherapy.
Total Femur Replacement After Tumor Resection: Limb Salvage Usually Achieved But Complications and Failures are Common
Primary bone or soft tissue tumors of the femur sometimes present with severe and extensive bone destruction, leaving few limb-salvage options other than total femur replacement. However, there are few data available regarding total femur replacement and, in particular, regarding implant failures.
A High-grade Sarcoma Arising in a Patient With Recurrent Benign Giant Cell Tumor of the Proximal Tibia While Receiving Treatment With Denosumab
A giant cell tumor of bone is a primary benign but locally aggressive neoplasm. Malignant transformation in a histologically typical giant cell tumor of bone, without radiotherapy exposure, is an uncommon event, occurring in less than 1% of giant cell tumors of bone. Although surgery is the standard initial treatment, denosumab, a monoclonal antibody drug that inhibits receptor activator of nuclear factor-κB ligand (RANKL), has shown considerable activity regarding disease and control of symptoms in patients with recurrence, unresectable, and metastatic giant cell tumors of bone.
What Is the Outcome of Allograft and Intramedullary Free Fibula (Capanna Technique) in Pediatric and Adolescent Patients With Bone Tumors?
After bone tumor resection, reconstruction for limb salvage surgery can be challenging because of the resultant large segmental bony defects. Structural allografts have been used to fill these voids; however, this technique is associated with high complication rates. To circumvent the complications associated with this procedure, massive bony allografts have been supplemented with an intramedullary vascularized free fibula. However, few studies have examined the outcomes using this technique in the pediatric and adolescent populations.
Are Allogeneic Blood Transfusions Associated With Decreased Survival After Surgery for Long-bone Metastatic Fractures?
Previous studies have shown that perioperative blood transfusion increases cancer recurrence and decreases patient survival after resection of primary malignancies. The question arises whether this association also exists in patients with already disseminated disease undergoing surgery for metastatic long-bone fractures.
