Abstract
OBJECTIVES: The aim of this study was to discuss the relationship between Ki-67 values and the degree to which chordoma invade the clivus, and to certify that the prognosis of chordoma is worse when it invades the middle and lower clivus than when it does not.
METHODS: We collected 56 cases of first-time chordoma illness in which patients received no treatment before surgery. Patients underwent craniocerebral magnetic resonance imaging and skull-base 3D-CT before the operation. We divided patients into two groups depending on the extent to which the middle and lower clivus were invaded. We classified patients with chordoma that did not significantly invade the middle and lower clivuses into a 'non-invasive' group and the others into an 'invasive' group. Ki-67 values were extracted from the pathological report after surgery. We use an independent chi-square test to indicate that Ki-67 values for the invasive group were higher than those for the non-invasive group .
RESULTS: We grouped the data and did a statistical analysis. We found that the Ki-67 values are > 5% for most patients in whom chordoma have eroded the middle-lower clivus, while it is ≤ 5% for patients in whom the middle-lower clivus region has not been invaded. Therefore, there is a correlation between Ki-67 value and the region of chordoma invading the clivus.
CONCLUSION: Statistical analysis revealed that Ki-67 values when the chordoma invaded the middle and lower clivus were significantly higher than when it did not. Thus, we can conclude that the prognosis is worse when chordoma invade the middle and lower clivus.
