ALBORES ZUNIGA, OLIVER et al. SCHWANNOMAS MEDIASTINALES: COMUNICACIÓN DE CASOS Y REVISIÓN DE LA LITERATURA. Rev. Inst. Nal. Enf. Resp. Mex. [online]. 2004, vol.17, n.4, pp.256-260. ISSN 0187-7585.
Introduction: Mediastinal tumors include an heterogenous group of neoplasms with variable biological behavior. In Mexico they represent 0.88% of all neoplasms. Thirty to 76% of these tumors are malignant; of these, 53% are neurogenic. Objectives: To study the frequency of mediastinal Schwannomas at our institute. Material and methods: A chart review of mediastinal tumors from 1980 to 2003 was done. Age, sex, clinical presentation, radiological features, previous diagnoses and treatments, histology, treatment and results were recorded. Results: 109 patients with mediastinal tumors were treated in the National Institute of Cancer from 1980 to 2003; 9 cases were tumors of neuroepithelial origin, 4 patients were taken to surgery. Histology and size were factors that influenced the result. Complete resection is the standard of care; adjuvant radiotherapy is useful.
Keywords : Mediastinal tumors ample; resection Schwannoma; neuroepitelial tumors.
