The success rate of sacral chordoma surgery will be about 90% or more, but we must also pay attention to a problem, although it is possible to achieve a complete cut of the sacral chordoma in the process of surgery, but only the case of the naked eye, in order to think in terms of the cells, it is likely that there is no way to achieve a complete cut, more or less there is always a certain residue. In the process of the first surgery, there is no special problem to achieve a complete surgical excision, but in the later stage, there may be some cells remaining in the bone seam or other bone, which may induce recurrence in the later stage. Although the surgery is successful, radiotherapy or even chemotherapy is needed in the later stage to reduce the probability of recurrence of chordoma and increase the cure rate.
