Abstract Chordomas and chondrosarcomas are rare tumors in children, even more so than in adults. Pediatric chordomas predominantly occur in the head and neck. In children, chondrosarcomas occur more frequently…

Abstract Protons are currently the most frequently used ions in the radiation treatment of chordomas and chondrosarcomas. Because of their biological and physical advantages, carbon ions promise further improvement in…

Abstract Chordomas and chondrosarcomas of the base of the skull and cervical spine are vexing therapeutic problems because of their location and proximity to several critical structures. Recurrence after surgery…

Abstract Background: Negative surgical margins are uncommon for skull base, spinal/paraspinal sarcomas. As such, preoperative and/or postoperative radiation therapy is often recommended to improve local control (LC). Surgical resection achieving…

Abstract While surgical excision represents the primary curative modality for chondrosarcomas and chordomas, tumor-free surgical margins can be difficult or impossible to achieve in the spine without significant morbidity. Therefore,…

Abstract Chordomas are slow-growing tumors of bone thought to arise in notochord remnants. They are rare, locally aggressive, and infiltrative tumors that can occur anywhere along the axial skeleton. Optimal…

Abstract The posterior approach to sacral sarcoma resection can be compartmentalized into eight parts. Sequentially accomplishing these eight steps offers a convenient way to study the surgical anatomy of the…

Abstract Chordomas and chondrosarcomas of the base of the skull are difficult to manage because of their location and proximity to critical structures. Since recurrence after surgery alone is common,…

Abstract Chordoma is a rare, slow-growing, malignant bone tumor with an insidious presentation. Consequently, diagnosis is often delayed, particularly for sacral tumors, which can reach large proportions before becoming symptomatic….
