- W2751444328 abstract "Numerous approaches have been reported in the management of skull base chondrosarcomas. Data are lacking for surgical outcomes by the tumor site of origin.To provide insight into outcomes by site of origin and factors affecting resection in order to aid in surgical approach selection.A retrospective review was conducted of 49 patients with chondrosarcoma treated at our institution. Charts were reviewed for tumor- and treatment-related factors. Extent of resection was the primary outcome, while neurological function and surgical complications were secondary outcomes. Statistical analyses were performed assessing variables for their impact on the primary outcome.The gross total resection rate for the overall cohort was 67.3%, and 97.8% of patients were either neurologically stable or improved postoperatively. A petroclival site of origin had lower rates of resection vs all other sites (P < .05). Histology and previous surgery did not predict outcome (P > .05), while previous radiotherapy and cavernous sinus invasion correlated with a subtotal resection (P < .05). In the petroclival cohort, clival, jugular tubercle, and soft tissue involvement correlated with a subtotal resection (P < .05). An endoscopic endonasal transpterygoid approach alone or combined with a transcranial approach yielded the highest resection rates for petroclival tumors (P < .05).Chondrosarcomas pose unique challenges based on the site of origin and pattern of extension. While current surgical strategies appear to yield adequate results at a majority of skull base sites, petroclival tumors represent a particular cohort in which improvement is needed. Based on our analysis, strategies incorporating both endoscopic and transcranial skull base approaches are likely necessary to achieve optimal outcomes." @default.
