Background: En bloc vertebral resection of locally invasive T4 lung cancers led to the development of a surgical sequence for resection; posterior stabilization, reposition, thoracotomy, lobectomy, vertebrectomy, and anterior spine stabilization in 1 procedure. This technique expanded indications for vertebrectomy to selected patients with sarcoma and metastatic disease. We review our experience to identify areas for clinical improvement.
Methods: Operative case logs were cross-checked with billing data from 2003 to 2014 with Current Procedural Terminology (CPT, American Medical Association) codes for vertebrectomy. Thirty-two cases involving en bloc resection of malignancy invading at least 1 thoracic vertebra were selected. Outcomes data were analyzed using summary statistics.
Results: Series includes 14 men and 18 women, median age 50 years. Twenty-five patients (78%) received preoperative chemoradiation. Nineteen total and 13 partial vertebrectomy were performed. Average number of vertebrae resected was 1.6 (range, 1 to 4). Median operative length was 8.5 hours (range, 2.8 to 14.5), mean blood loss 923 mL (SD ± 477 mL), and median length of stay 8 days (range, 3 to 56). Major morbidity followed 56% of cases. Thirty-day mortality was 3%. Overall median survival was 43.6 months, 1-year survival was 73.6%, and 5-year survival was 40.3%.
Conclusions: En bloc vertebrectomy for malignant disease is feasible. Our 1 stage and 2 team approach allows completion of the operation within a standard day, but is associated with long operative time. Complication rates may improve with decreased operative times. Review of available data warrants future prospective studies.
