Abstract

Objective: Chordoma is a rare malignant bone tumor with a poor outcome. Although radiotherapy and gamma knife surgery have been used for treatment, providing a cure for the tumor is not easy, because of the frequent recurrences. Molecular targeted therapy against tyrosine kinases has been effective in the treatment of malignancies such as breast and lung cancers and brain tumors. We aimed to analyse the histopathological features of chordomas and the immunoexpression profiles of the three receptor tyrosine kinases of EGFR, c-Met and c-Erb-B2 in chordomas. We have correlated these results with recurrence and overall survival status of the patients.
