Sacrococcigeal and vertebral chordomas. Report of three cases and review of the literature.

ABSTRACT

Three cases of sacrococcygeal and vertebral chordoma are described. Histogenetic and anatomopathological aspects with particular reference to differential diagnosis from similarly distributed neoplasias are discussed. Anti-cytoskeleton monoclonal antibodies were used to this purpose. The clinical profile of sacrococcygeal and vertebral chordomas is characterized by a pronounced metastatic potential; radiation treatment can only partially counter their biological behaviour, while chemotherapy has proved little or no effectiveness. Where possible, radical surgery is currently the only treatment to guarantee long-term survival or complete cure. Palliative surgery, associate with efficient painkilling, offers a better quality of life and slows down the progress of the disease.
