Treatment of primary vertebral tumors.

Advances in the treatment of disease and detection through advanced imaging have led to an increase in the discovery of vertebral tumors. Although the majority of symptomatic spinal lesions are metastatic in origin, a significant number of them arise primarily in the spine. These lesions encompass a wide variety of tumor types classified by their cell of origin: bony tumors, cartilaginous tumors, vascular tumors, plasma cell dyscrasias, and tumors that arise from embryonic rests. Further classification of these tumors into malignant or benign subtypes is based on their clinical progression, histopathological evidence of invasiveness, and response to therapy. We provide a brief overview and description of primary tumors as well as treatment paradigms for the individual tumor types. Mt Sinai J Med 76:499-504, 2009. (c) 2009 Mount Sinai School of Medicine.
