STUDY DESIGN.: Ambispective cohort study OBJECTIVE.: To determine whether the application of the Enneking classification in the management of spinal chondrosarcomas influences local recurrence and survival. SUMMARY OF BACKGROUND DATA.: Primary spinal chondrosarcomas are rare. Best available evidence is based on small case series, thus making it difficult to determine optimal management and risk factors for local recurrence and survival. METHODS.: The AOSpine Knowledge Forum Tumor developed a multicenter ambispective database of surgically treated patients with spinal chondrosarcoma. Patient data pertaining to demographics, diagnosis, treatment, cross-sectional survival, and local recurrence were collected. Tumors were classified according to the Enneking classification. Patients were divided into two cohorts: Enneking appropriate (EA) and Enneking inappropriate (EI). They were categorized as EA when the final pathological assessment of the margin matched the Enneking recommendation, and otherwise, they were categorized as EI. RESULTS.: Between 1987 and 2011, 111 patients (37 female; 74 male) received surgical treatment for a primary spinal chondrosarcoma at a mean age of 47.4?±?15.8 years. Patients were followed for a median period of 3.1 years (range?=?203 days-18.7 years). Median survival for the entire cohort was 8.4 years postoperative. After 10-years postoperative, 36 (32%) patients died and 37 (35%) patients suffered a local recurrence. Twenty-three of these 37 patients who suffered a local recurrence died. Sixty (58%) patients received an EA procedure while 44 (42%) received an EI procedure. EI patients had a higher hazard ratio for local recurrence compared to those who received an EA procedure (P?=?0.052). Local recurrence was strongly associated with chondrosarcoma-related death (RR?=?3.6, P?
