RESUMEN
BACKGROUND: Craniofacial chondroid tumors (CFCTs) constitute less than 1% of all intracranial mass lesions. No protocol for evaluation and management of CFCTs is developed at the moment. MATERIALS AND METHODS: We analyzed 51 patients with CFCTs operated on in Burdenko Neurosurgical Institute from 1980 until 2012, which included chondroma (15), chondroblastoma (3), chondromyxoid fibroma (11), and chondrosarcoma (22). Age varied from 2 to 76 years (mean, 40 y); the series included 23 women and 28 men. All tumors were divided into 4 groups: midline unilateral (8),midline bilateral (21), anterolateral (19), and lateral (3). This division was based on differences in surgical approaches (P = 0.009). RESULTS: All patients underwent surgical treatment. Complete removal was achieved in 20; subtotal, in 21; and partial, in 10. Two patients died, and early complications were observed in 10 cases. Early outcomes correlated with the benign nature of the tumors (P = 0.002). Follow-up data were available in 22 patients. Fifteen of 51 patients were reoperated on because of recurrence (a total of 43 reoperations were performed). The mean recurrence-free period was 45 months. In 3 patients, the tumor metastasized, and malignant transformation was observed in 3 cases. Sixteen patients received postoperative radiation therapy. Delayed sequelae occurred in 5 observations, and 5 patients died during long-term follow-up. Three-year survival in benign and malignant tumors was 87.5% and 55.6%, respectively, and 5-year survival was 83.3% and 40.0%, respectively. CONCLUSION: Surgical resection is the mainstay in treatment of both benign and malignant craniofacial tumors, and adjuvant radiation therapy is mandatory in malignant lesions; however, it should be avoided in benign lesions.
