Abstract
Olfactory neuroblastoma (ONB) is a rare neoplasm originating from the olfactory neuroepithelium representing 3-6% of tumors of the sinonasal tract. ONB require multi-disciplinary care. Historically, the gold standard surgical procedure for ONB has been open craniofacial resection. In the last years, endoscopic endonasal approaches have been largely introduced with lower complication rates, shorter hospital stay, and similar clinical outcome. Radiotherapy plays an important role in the management of ONB, however there are not generally accepted recommendations for its application. Although there is agreement that multimodal therapy is needed, the optimal use of chemotherapy is still unknown. The rarity of the disease, makes difficult to draw definitive conclusions about the role of systemic treatment in induction and concomitant setting.

Abstract
This chapter examines the results of GKNS on a variety of extraparenchymal skull base tumors some benign and some malignant. For the benign tumors there is good evidence on the effectiveness of the method for pretty much all diagnoses. For malignant extraparenchymal tumors the results are more limited and GKNS only has a supportive role in these lesions.

Esthesioneuroblastoma with recurrent dural metastases: Long-term multimodality treatment and considerations. Surg Neurol Int 2021; 12:606. [PMID: 34992923 PMCID: PMC8720440 DOI: 10.25259/sni_821_2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 11/14/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Esthesioneuroblastoma (ENB) is a rare malignant disease and treatment protocols have not been standardized, varying widely by disease course and institutional practices. Management typically includes wide local excision through open or endoscopic resection, followed by radiotherapy, chemotherapy, and stereotactic radiosurgery. Tumor control can differ on a case-by-case basis. Herein, the complex management of a rare case of recurrent disease with multiple dural metastases is presented. Case Description: A 60-year-old patient was diagnosed with ENB after presenting with anosmia and epistaxis. The patient underwent combined endonasal and transfrontal sinus craniofacial resection, followed by proton beam radiation therapy and chemotherapy. Subsequently, he developed a total of 25 dural metastases that were controlled with repeated Gamma Knife Radiosurgery (GKRS). In spite of post-treatment course that was complicated by radiation necrosis and local vasculopathy, the patient made significant recovery to functional baseline. Conclusion: The management of ENB entails multimodality and multidisciplinary care, which can help patients obtain disease control and long-term survival. Recurrent ENB dural metastases can behave as oligometastatic disease manageable with aggressive focal GKRS. As prognosis continues to improve, chronic treatment effects of radiation in such cases should be taken into consideration.

Abstract
Background Consensus in timing of radiotherapy is yet to be established in esthesioneuroblastoma (ENB). Objective This study was aimed to investigate if planned adjuvant radiotherapy improves tumor control after complete margin negative resection of low Hyams' grade (1 or 2) ENB. Methods A retrospective review of patients with pathologically confirmed negative margin resection of Kadish's stage B or C and Hyams' grade 1 and 2 ENBs was conducted. Seventeen patients meeting the criteria were divided into the following two groups for cohort study: (1) those who underwent planned immediate postoperative adjuvant radiotherapy (IR group) and (2) those who did not (delayed radiotherapy [DR] group). Results The IR group included nine patients (Kadish's stage B in one and stage C in eight; Hyams' grade 1 in two and grade 2 in seven). Mean follow-up was 140.8 months. Seven patients (78%) had disease progression (DP) at a median of 88 months (four with cervical lymph node metastasis [CLNM], one with distant metastasis, and two with both local recurrence and CLNM). One patient experienced frontal lobe abscess. The DR group included eight patients (Kadish's stage B in six and stage C in two; all Hyams' grade 2). Mean follow-up was 123.3 months. Four (50%) patients who developed DP (all local recurrence) were salvaged with surgery and adjuvant radiotherapy at a median of 37.5 months. There was no statistically significant difference in DP rate ( p = 0.23), time to DP ( p = 0.26), or the local tumor control rate ( p = 0.23). Conclusion In our limited cohort, immediate postoperative radiotherapy did not demonstrate superiority in tumor control, although risk of radiotherapy toxicity appears low.

Abstract
INTRODUCTION Many controversies exist in the diagnosis and management of this aggressively malignant condition, mainly because of limited literature and lack of randomized control trials, resulting in nonstandardized treatment methods. We performed a comprehensive review of the literature to identify management approach and treatment options for esthesioneuroblastoma. METHODS An extensive review of the published literature was conducted in PubMed, OVID Medline, and EMBASE journals for studies of esthesioneuroblastoma. Terms for search included esthesioneuroblastoma (ENB) and olfactory neuroblastoma (ONB). No date restrictions were used. RESULTS The search yielded 3876 related articles. Cross-checking of articles led to exclusion of duplicate articles. The remaining 1170 articles were screened for their full text and English language availability. Of 609 full-text articles available, animal studies, irrelevant articles, and studies with mixed/confusing data were excluded. We finalized 149 articles pertaining to the topic, including 119 original research articles, 3 book chapters, 11 reviews, 9 case reports, and 7 case series. CONCLUSIONS Surgical resection followed by radiotherapy is the standard for treatment for higher-grade lesions. The endoscopic endonasal approach is gaining further recognition with more favorable outcomes and better survival than for open surgery. Postoperative radiotherapy is associated with the highest overall survival and shows benefit for patients with higher-stage disease and those who receive chemotherapy. Recurrence rates after treatment vary drastically in the literature and, therefore, prolonged follow-up with repeated imaging is recommended. Lifelong surveillance is recommended because of late recurrences associated with this tumor.

Abstract
OBJECTIVE To quantify the rate of late intracranial recurrences among esthesioneuroblastoma patients treated with surgical resection and postoperative radiation. STUDY DESIGN Retrospective review. METHODS All 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. RESULTS 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 had ≥ two 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. CONCLUSION Esthesioneuroblastoma patients presenting with intracranial extension are at substantial and unique risk for long-term dural-based relapse. LEVEL OF EVIDENCE 4. Laryngoscope, 128:2226-2233, 2018.

Abstract
BACKGROUND: Esthesioneuroblastoma (ENB) is an uncommon neoplasm arising from the olfactory mucosa. The optimal treatment regimen for ENB remains unclear. This study aims to evaluate its clinical features, long-term outcomes and explore optimal treatment patterns. METHODS: Clinical data of consecutive 44 ENB patients were reviewed retrospectively. The correlation between clinical features and treatment approaches were analyzed, with several prognostic factors explored meanwhile. RESULTS: The age of onset of ENB showed a bimodal distribution, with peaks at 10~20 and 50~60 years. The median follow-up time was 84 months (range, 27~198 months).The 5-year overall and progression free survival rates were 42.7% and 39.1%, respectively, with 10-year rates of 28.9% and 21.7% respectively. Overall, 19 patients developed recurrent disease. Patients undergoing surgery combined with adjuvant radiotherapy had significantly higher 5-year overall survival (67.5% vs. 33.3%, P=0.043) and progress-free survival (60.0%vs. 18.7%, P=0.008) than those receiving other treatment approaches. No-Skin-involved ENB was associated with markedly better 5-year overall survival (45.5%vs.0 %, P=0.038) and progress-free survival (31.3% vs. 0 %, P=0.001) compared with skin-involved tumor. CONCLUSIONS: ENB is a rarely malignant tumor with high probability of locoregional recurrence and poor survival. Surgical resection followed by radiotherapy has been shown to achieve optimal local control and overall survival.

Abstract
Management of tumors of the central nervous system is challenging for clinicians for various reasons, including complex diagnostic procedures, limited penetration of drugs into brain tissue, and the prerequisite to preserve brain function in any case of therapeutic intervention. Therapeutic success is dependent on the efforts, skills, and cooperation of involved specialists and disciplines. Knowledge and ability to apply adequate therapeutic modalities in an interdisciplinary approach in due time are crucial, necessitating coordination of diagnostic procedures and therapeutic interventions by means of multidisciplinary brain tumor boards. In this chapter we present in brief the essential current standards and future perspectives for therapy modalities that complement surgery of brain tumors.

Abstract
Physicians are being challenged to obtain data for outcomes research and measures of quality practice in medicine. We developed a prospective data collection system (registry) that provides data points across all elements of a neurosurgical stereotactic radiosurgery practice. The registry architecture is scalable and suitable for any aspect of neurosurgical practice. Our purpose was to outline the challenges in creating systems for high quality data acquisition and describe experiences in initial testing and use. Over a two year period, a multicenter team working with software engineers developed a comprehensive radiosurgery registry based on a MS-Sequel® server platform. Three neurosurgeons at one center were responsible for final editing. Alpha testing began in September 2012 and server-based beta testing began in February 2013. The major elements included demographics, disease-based items (47 categories for different brain tumors, vascular malformations, and functional disorders) with relevant clinical grading systems, treatment-based items (imaging, physics, clinical), and follow-up data (clinical, imaging, subsequent therapeutics). Nine hundred patients were entered into the registry at one test center, with new entries and follow-up data entered daily at the point of contact. With experience, the mean time for one new entry was 6 minutes. Mean time for one follow-up entry was 45 seconds. The system was made secure for individual use and amenable for both data entry and research. Analytics used different filters to create customized outcomes charts as selected by the user (e.g., survival, neurologic function, complications). A local or multicenter prospective data collection registry was created for use across 47 clinical indications for stereotactic cranial radiosurgery. Further refinement of fields and logic is ongoing. The system is reliable, robust, and allows use of rapid analytical tools. Large medical registries will become widely used for collection and analysis of large data sets and should have broad applicability to many other elements of neurosurgical and medical practice.
