  RESULTS
  All of the 8 patients with benign clival tumors (6 cases with chordomas and 2 with meningiomas) had over 2-8 years survival and no severe complications after the surgical procedures and adjuvant radiotherapy. Fourteen of the 19 patients with malignant tumors had over 2-6 years survival (a survival rate of 73.7%) after the surgical procedures, the adjuvant chemotherapy and radiotherapy.
