Prognostic Value of a Category Based on Electron Microscopic Features of Clival Chordomas

The present study demonstrates the utility of the ultrastructural features in the prognostic outcome of patients with chordoma. According to the ultrastructures of chordomas, they can be divided into CDT and MRT. CDT chordoma cells have a more aggressive proliferative ability. Patients with CDT have a poor prognostic factor in clival chordoma, which has a higher risk of recurrence and a shorter survival.
