Multicenter Study
Chordoma of the mobile spine and sacrum: a retrospective analysis of a series of patients surgically treated at two referral centers.
Chordoma is a rare tumor, and its natural history is still not well known. ⋯ Tumor size and surgical margins affected outcome only on initial presentation. However, wide surgery was feasible in a minority of cases. Most patients died of local-regional disease even when metastases occurred. Indeed, long-term prognosis was such that disease-free survival at 10 years was only 26%.
