BACKGROUND: Since chordoma is refractory to chemotherapy and conventional radiotherapy, radical surgical resection is mandatory. However, it is surgically demanding in the craniocervical junction (CCJ) and upper cervical spine. OBJECTIVE: To analyze long-term surgical results of cervical chordomas. METHODS: We retrospectively reviewed 12 consecutive patients who underwent surgical treatment for CCJ or upper cervical chordomas from 2001 to 2009 in 2 academic institutions. We analyzed the progression-free survival and overall survival and compared the results between gross total resection (GTR) cases and partial resection (PR). Complications were analyzed by comparing primary and recurrent tumor. We also delineated the type of radiotherapy. RESULTS: Of the 12 patients, 5 underwent GTR and 7 underwent PR. GTR of the tumor was achieved by intralesional piecemeal removal. No recurrence occurred in the GTR group. PR group had 6 cases of regrowth (85.7%). Ten patients (83.3%) underwent any kind of radiation therapy. There were 3 (60%) patients in the GTR group and 7 (100%) in the PR group. Compared to PR, GTR revealed a better 3-yr progression-free survival rate (100% vs 14.3%) as well as a better 3-yr overall survival rate (100% vs 71.4%). Surgical complication rate (40% for GTR vs 42.9% for PR) was not significantly different between the groups. The surgical complication rates of primary and revision surgery were 25% and 75%, respectively. Complication associated with radiation occurred in 2 patients. CONCLUSION: Gross total intralesional piecemeal resection with perioperative radiation therapy is an acceptable strategy for CCJ and the upper cervical chordoma management.
