Dural recurrence among esthesioneuroblastoma patients presenting with intracranial extension.
LARYNGOSCOPE(2018)
摘要
ObjectiveStudy DesignTo quantify the rate of late intracranial recurrences among esthesioneuroblastoma patients treated with surgical resection and postoperative radiation. Retrospective review. MethodsResultsAll patients receiving definitive-intent therapy for esthesioneuroblastoma between March 1995 and September 2015 were reviewed. Presenting disease extent was categorized based on radiologic, operative, and pathologic findings. Between-group survival differences were assessed using Kaplan-Meier method and log-rank test. Multivariate analyses were performed using Cox proportional hazards model. Of 38 patients initially treated at our institution, 53% (20 of 38) presented with intracranial extension. At a median follow-up of 90 months (range, 6-199), 37% (14 of 38) recurred; 5- and 8-year disease-free survival rates were 69% and 54%; and overall survival rates were 81% and 72%, respectively. Among these patients, the dura was the most commonly involved site of relapse (8), followed by local (6), regional (5), and distant extracranial (3) sites; and five patients hadtwo categories of failure. Eight-year dural disease-free survival was 57% versus 90% (P=0.017) and 0% versus 87% (P<0.0001), with and without intracranial extension and subtotal resection, respectively. Of six patients treated at recurrence, five (83%) experienced dural-based failure such that, among all 44 patients, 13 (65%) of 20 recurrences involved the dura. After dural recurrence, the median survival time was 42 months (range, 12-125); salvage treatments were effective in rare cases of isolated low-volume recurrence. ConclusionLevel of EvidenceEsthesioneuroblastoma patients presenting with intracranial extension are at substantial and unique risk for long-term dural-based relapse. 4.
