Aim: This review aimed to summarize the clinical outcomes in relation to tumor resection
margins of cervical chordomas. Methods: Studies that described any surgical intervention
for cervical chordoma were identified. Cervical chordomas with cranial or spinal extension,
purely retropharyngeal chordomas or where resection type was not reported, were excluded
from the study. Results: Seventy-six articles were obtained and these reported a total of 195 patients. Seventy-six
percent cervical chordoma patients had intralesional resection with adjuvant radiotherapy.
Ninety-two percent chordoma recurrences and all chordoma metastases occurred in patients
with intralesional resection. En bloc surgeries were longer (900 min vs. 619 min)
and staged surgeries. Intralesional surgeries (2899 ml vs. 2661 ml) had greater intraoperative
blood loss. Vertebral artery and nerve root sacrifice were greater in en bloc patients
(35%, 39%) compared to intralesional patients (17%, 10%). Postoperative complications
were more common in en bloc (54%) than in intralesional patients (11%). Conclusions: En bloc resection cervical chordomas are associated with less recurrence and no metastasis
compared to intralesional resection. En bloc is possible through wide exposure of
the vertebrae via a multidisciplinary team approach and utilization of particular
surgical equipment. The higher rate of complications associated with en bloc surgeries
may be acceptable, particularly when there is a chance of cure of disease.
