Tumores Raquídeos: Experiencia del Departamento de Neurocirugía del Hospital Clínico de la Universidad de Chile

Introduction: Spinal tumors are rare neoplasms representing 2%-4% of all central nervous system tumors, with an estimated incidence of 0.74 per 100,000 inhabitants per year and limited national epidemiological data available in Chile. Objective: To analyze the epidemiological, histological, and anatomical characteristics of spinal tumors diagnosed at the Hospital Clínico de la Universidad de Chile between 1999 and 2020. Materials and Methods: A descriptive retrospective study was conducted. Patients were identified through ICD-10 codes and the corresponding surgical procedure. Variables including sex, age, clinical presentation, anatomical location, and histological type were analyzed. Results: A total of 96 patients were included (52.09% female), with a mean age of 50.63 years. The most frequent symptom was axial pain (52.08%). The most common tumor was schwannoma (28.13%), followed by ependymoma (18.75%) and metastases (15.63%). The predominant location was lumbar (45.83%), and 70.17% of tumors were intradural. Conclusion: The findings are consistent with the international literature, providing relevant local epidemiological data to guide the diagnosis and management of spinal tumors in Chile.
