Spinal chondrosarcomas are rare primary malignant neoplasms composed of cartilage-producing cells. They are slow-growing but locally aggressive lesions that have high rates of recurrence and progression after treatment. We provide the largest comprehensive analysis of prognostic factors, treatment modalities, and survival outcomes in patients with spinal chondrosarcoma using a large, prospectively collected national database. ⋯ Surgical resection significantly improves overall survival in patients with spinal chondrosarcoma. In those patients receiving radiation, those who receive high doses have improved overall survival compared with those who receive lower doses. Further studies into optimal radiation modality and doses are required.

Spinal hemangiomas are common primary tumors of the vertebrae. Although these tumors are most frequently benign and asymptomatic, they can rarely exhibit aggressive growth and invasion into neighboring structures. Treatment for these aggressive variants is controversial, often involving surgery, chemotherapy, and/or radiotherapy. This study sought to investigate current trends affecting overall survival (OS) using the National Cancer Database (NCDB) and to formulate treatment recommendations. ⋯ This retrospective analysis finding that treatment with surgical resection and/or radiotherapy is associated with increased OS constitutes the largest cohort of patients with aggressive vertebral hemangiomas to date. Given that the mean OS of the study cohort was 1.94 years, our findings suggest that the optimal treatment regimen to maximize survival should consist of early surgical resection with adjuvant high-dose radiotherapy.

Glioblastomas (World Health Organization grade IV) are aggressive primary neoplasms of the central nervous system. Spinal metastasis occurs supposedly in 2%-5% of patients. This percentage may be only the tip of iceberg because most succumb to the disease before clinical detection and few documented cases are reported. ⋯ Spinal and dural metastasis should always be suspected in patients with glioblastoma with signs and symptoms not explained by primary lesion. A regular protocol with postcontrast magnetic resonance imaging before and after initial surgery is mandatory to detect spinal metastasis before it becomes clinically apparent, thereby improving the prognosis and quality of life in patients.

Comparative Study
Surgery Versus Radiofrequency Ablation in the Management of Spinal Osteoid Osteomas: A Spine Oncology Referral Center Comparison Analysis of 138 Cases.
Osteoid osteomas (OOs) are benign bone forming tumors that, usually, occur in the extremities, with about 10% of them arising in the spine more commonly in the posterior elements. The aim of this study is to evaluate the long-term results of patients suffering from spinal OO treated with surgery and radiofrequency ablation. ⋯ Surgery and RFA are both safe and effective interventional procedures for the management of spinal OO, although RFA is associated with a greater recurrence rate. Treatment should be tailored according to the relationship of lesions with neural structures and to advantages and disadvantages of each technique.

Giant cell tumors (GCTs) constitute 5% of all primary bone tumors with spinal GCTs (SGCTs) accounting for 2%-15% of all GCTs. The standard of care for SGCT has been maximal surgical resection. However, many adjuvant therapies have been used owing to the difficulty in achieving gross total resection combined with the high local recurrence rate. The purpose of the present study was to analyze the incidence, management, and outcomes of SGCT. ⋯ SGCT is a rare primary bone tumor of the vertebral column. The standard of care has been surgical resection with the goal of gross total resection; however, adjuvant therapies have often been used. Our study found that surgical resection significantly improved OS and that immunotherapy neared significance in improving OS.
