[Treatment results in chordomas of the saccrococcygeal area]

The influence of various factors on the survival of 40 patients with sacral chordoma is considered. Irrespective of type of therapy, the 5-year survival after treatment of malignant chordoma was 31.5 +/- 14.6%, while in cases of benign chordoma it was 73.9 +/- 10.0%. The 10 year survival rates were 31.5 +/- 14.6 and 34.2 +/- 10.8%, respectively. The 5-year survival rates increased 3-fold after ablastic removal of tumor and by 37.9% after combination therapy (surgery + radiation). The age and sex differences had no significant prognostic value. Radical ablastic removal of sacral chordoma is of great prognostic value since it ensures favorable prognosis, irrespective of morphological type of tumor.
