Assessment of the Extent of Surgical Resection as a Predictor of Survival in Patients With Primary Osseous Spinal Neoplasms
Studies using the Surveillance, Epidemiology, and End Results (SEER) registry, however, may provide a better source of understanding for rare pathologies. This registry is the most comprehensive source of cancer information because it collects incidence and survival data for patients with cancer from 26% of the population in the United States. The goal of the present study was to conduct a large population-based study using the SEER registry to understand whether surgical resection compared with biopsy was associated with improved survival for patients with primary nonmetastatic chordomas, chondrosarcoma, osteosarcomas, and Ewing sarcoma. This understanding may help clarify the role of surgery in maximizing survival for patients with malignant primary bone tumors.
