Abstract
BACKGROUND Esthesioneuroblastoma (ENB), a rare malignancy arising from the olfactory epithelium, poses clinical challenges owing to its propensity for local invasion and recurrence. Its management typically involves surgical resection and adjuvant radiotherapy. However, debate persists regarding the optimal treatment strategy, particularly the use of elective nodal irradiation (ENI). This study aimed to investigate recurrence patterns in patients with localized ENB treated with surgery and adjuvant radiotherapy without ENI. METHODS Our retrospective analysis included patients who underwent surgery followed by adjuvant radiotherapy for treatment of ENB between January 2011 and November 2022. Patients with incomplete data or who had received neoadjuvant radiotherapy were excluded. Patient characteristics, radiotherapy data (type, dose, and duration), and follow-up data were collected. Recurrence patterns were evaluated, and overall survival (OS), disease-free survival (DFS), and local control rates were determined using the Kaplan-Meier method. RESULTS Twelve patients with ENB (median age, 56 years) were included. Most had stage C disease. The median radiation dose was 60 Gy, and the median treatment duration was six weeks. Only one death was confirmed during the observation period, and the five-year DFS rates were 64.3%. Local control was achieved in 11 patients, with only one experiencing local recurrence. Regional lymph node recurrence occurred in three patients and was successfully managed via neck dissection. The timing of recurrence varied, emphasizing the importance of long-term surveillance. CONCLUSION Adjuvant radiotherapy without ENI is a viable treatment option for ENB, resulting in favorable local control and OS outcomes. Regional lymph node metastases were observed but effectively managed via salvage therapy. Prospective studies with larger cohorts are warranted to confirm the effectiveness of this treatment strategy and to define optimal radiotherapy fields.

Abstract
Olfactory neuroblastoma (ONB) is a malignant neuroendocrine neoplasm with a usually slow course, but with considerable recurrence rate. Many neuroendocrine tumors have shown good response to the treatment with somatostatin analogs and somatostatin radioreceptor therapy. In ONBs, there are scarce data on somatostatin-based treatment and the cellular expression of somatostatin receptors (SSTR), the prerequisite for binding and effect of somatostatin on normal and tumor cells. The aim of our study was to investigate the immunohistochemical expression of SSTR2A and SSTR5 in a cohort of 40 ONBs. In addition, tissue microarrays containing 40 high-grade sinonasal carcinomas as well as 6 sinonasal lymphomas, 3 rhabdomyosarcomas, and 3 Ewing sarcomas were evaluated. Volante system was applied for staining evaluation. Thirty cases (75%) were immunopositive for SSTR2A and 3 (7.5%) for SSTR5. Among the 30 SSTR2A-positive ONBs, 19 tumors (63.3%) scored 2+ and 11 (36.7%) scored 3+. All SSTR5-positive ONBs scored 2+. Neither sinonasal carcinomas nor sinonasal small round blue cell neoplasms expressed SSTR2A or SSTR5. The frequent expression of SSTR2A provides a rationale for radioreceptor diagnosis and therapy with SST analogs in ONBs. SSTR2A expression in ONBs is a helpful adjunct in the differential diagnosis of ONBs.

Abstract
Olfactory neuroblastoma (ONB, Esthesioneuroblastoma) is an infrequent neoplasm of the head and neck area derived from olfactory neuroepithelium. Despite relatively good prognosis a subset of patients shows recurrence, progression and/or metastatic disease, which requires additional treatment. However, neither prognostic nor predictive factors are well specified. Thus, we performed a literature search for the currently available data on disturbances in molecular pathways, cytogenetic changes and results gained by next generation sequencing (NGS) approaches in ONB in order to gain an overview of genetic alterations which might be useful for treating patients with ONB. We present briefly ONB molecular pathogenesis and propose potential therapeutic targets and prognostic factors. Possible therapeutic targets in ONB include: receptor tyrosine kinases (c-kit, PDGFR-b, TrkB; EGFR); somatostatin receptor; FGF-FGFR1 signaling; Sonic hedgehog pathway; apoptosis-related pathways (Bcl-2, TRAIL) and neoangiogenesis (VEGF; KDR). Furthermore, we compare high- and low-grade ONB, and describe its frequent mimicker: sinonasal neuroendocrine carcinoma. ONB is often a therapeutic challenge, so our goal should be the implementation of acquired knowledge into clinical practice, especially at pretreated, recurrent and metastatic stages. Moreover, the multicenter molecular studies are needed to increase the amount of available data.

Abstract
BACKGROUND Esthesioneuroblastoma (ENB) is a rare cancer of the nasal cavity in children. Radical surgery followed by postoperative radiation is considered the standard of care in adults. A similar approach in children can lead to significant long-term morbidity. PROCEDURE A retrospective multi-institutional review of patients less than 21 years of age diagnosed with ENB between 1990 and 2014 was performed. Clinical features, treatment, and outcome were obtained from the medical records. RESULTS Twenty-four patients were identified with a median age of 14 years (range 0.6-20 years) at diagnosis. The majority (75%) were females. Headache was the most common presenting symptom, followed by nasal obstruction and epistaxis. Eight patients had Kadish stage B tumors and 16 had Kadish stage C tumors. Nine patients had metastatic disease. Gross total resection was achieved at diagnosis in eight patients and after neoadjuvant chemotherapy in four patients. Twenty-one patients received radiation therapy (45-68.4 Gy). Thirteen patients received neoadjuvant chemotherapy with 84% objective response rate. Seven patients experienced disease progression or relapse-five in central nervous system, one local, and one in cervical lymph node. Fifteen patients were alive at the last follow-up. The 5-year disease-free survival and overall survival were 74% and 73%, respectively. Late effects were observed in 78% of long-term survivors. Four patients developed subsequent malignant neoplasms. CONCLUSIONS Pediatric ENB is a chemosensitive disease. Preoperative chemotherapy-based multimodal approach should be used in patients with advanced stage disease. Radiation therapy is effective for local control, but lower doses should be considered in children.

Abstract
Olfactory neuroblastoma (ONB) is a rare tumour of nasal cavity and paranasal sinuses that arises from the olfactory neuroepithelium and has unpredictable clinical course. As the sense of smell is phylogenetically one of the first senses and olfactory neuroepithelium is evolutionary conserved with striking similarities among different species, we performed an extensive analysis of the literature in order to evaluate the similarities and differences between animals and humans on the clinical, morphological, immunohistochemical, ultrastructural and molecular level. Our analysis revealed that ONB was reported mainly in mammals and showed striking similarities to human ONB. These observations provide rationale for introduction of therapy modalities used in humans into the veterinary medicine. Animal models of neuroblastoma should be considered for the preclinical studies evaluating novel therapies for ONB.

Abstract
Esthesioneuroblastoma (ENB) is a rare malignancy unique to the sinonasal tract. It arises from the olfactory epithelium and has a tendency to originate from one side of the nasal cavity and paranasal sinuses with frequent extension into the cranial cavity and orbit. There is a bimodal age distribution between 11 and 20 years and between 51 and 60 years. ENB accounts for approximately 2-3% of intranasal cancers. Due to the non-specific nature of the initial presentation and slow growth of the tumor, patients often have a long history before diagnosis. Physicians including pathologists are not always aware of distinctive features of ENB especially radiographic, histologic and immunohistochemical characteristics. Additional difficulty can be the fact that Esthesioneuroblastoma can histologically mimic many tumors within the sinonasal tract. We report on a 38-year-old male patient with a Kadish stage C tumor with frontal lobe invasion. The patient underwent a craniofacial resection with a combined head neck and neurosurgeon team. After the surgery postoperative radiotherapy was used. The aim of this study is to present the natural history of the malignancy, the diagnostic process, treatment and prognosis, based on the literature review.

Abstract
OBJECT There is no Class I evidence to guide the appropriate management of esthesioneuroblastoma (EN). Most data currently guiding treatment come from small- or modest-sized series gathered at individual centers that have concluded that surgery with radiotherapy is the preferred treatment. In this study, the authors summarize the published literature on treatment outcomes in patients with EN. The objective was to ascertain what variables predict prognosis in these patients and to determine the relative effect of different therapies. METHODS The authors identified 205 published studies containing treatment outcomes for surgery, radiotherapy, chemotherapy, or multimodal treatment. Using Kaplan-Meier analysis, the survival of patients who received surgery was compared with that in those who received surgery and radiotherapy. Additionally, Kadish staging was compared with low- and high-grade Hyams criteria to assess for subgroup prognostic significance in survival differences. RESULTS Nine hundred fifty-six patients met the inclusion criteria, with a median follow-up time of 3 years. Kaplan-Meier analysis demonstrated no difference in survival between patients who underwent surgery alone and those who underwent surgery plus radiotherapy at 5 years (78 vs 75%) or 10 years (67 vs 61%, respectively) (p = 0.3). Univariate analysis demonstrated worse survival in cases involving Kadish Grade C tumors, Hyams Grade 3 and 4 tumors, and in patients older than 65 years of age. Multivariate analysis demonstrated that Hyams Grade 3 and 4 lesions carried significant risk (proportional hazard = 4.83, p < 0.001) with 5- and 10-year survival of 47 and 31%. CONCLUSIONS A biopsy should always be obtained in cases suspected of EN because histology is a strong prognostic indicator and will help guide appropriate treatment. Unimodal surgery and combined surgery/radiotherapy appear to be of equivalent efficacy with respect to survival in patients with EN. Chemotherapy should be considered in high-grade EN.

Abstract
Olfactory neuroblastoma (esthesioneuroblastoma) is a rare neoplasm of the olfactory epithelium in the upper nasal cavity. Here, we report the case of a 69-year-old man who presented with massive progression of a metastatic esthesioneuroblastoma after endonasal resection, functional neck dissection, and radiotherapy of local and distant tumor relapses. After exhaustion of all conventional therapeutic options, we initiated treatment with the oral multityrosinekinase inhibitor sunitinib mesylate. Using this drug, significant improvement of clinical symptoms, disease stabilization, and recovery from Karnofsky index of 40% to 70% could be achieved in the absence of significant adverse drug effects. The patient died 15 months after initiation of sunitinib therapy due to complications of a traumatic femoral neck fracture without evidence of tumor progression. Immunohistochemical analysis of tumor tissue specimens obtained at initial surgery revealed ample expression of platelet-derived growth factor receptor (PDGFR)-b on stromal and endothelial cells. Sunitinib should be considered for palliative therapy of advanced esthesioneuroblastoma.

Abstract
INTRODUCTION Esthesioneuroblastoma (ENB) is an aggressive neuroectodermal malignancy in the upper nasal cavity with local infiltration and lymphatic or hematogenous metastasis. The purpose of this paper is to document three types of direct intracranial extensions by ENB using computed tomography (CT) and magnetic resonance imaging (MRI). METHODS Eleven patients with pathologically confirmed ENB were admitted in our hospital between December 2002 and December 2008. Their magnetic resonance (MR; n = 10) and CT (n = 8) images were retrospectively reviewed, and particular attention was paid to tumor location and extension, enhancement pattern, cervical lymph node metastasis, and Kadish stage. RESULTS The majority of patients were male (8/11) with Kadish stage C tumor (10/11). Three types of direct intracranial extension by ENBs were put forward according to their MR and CT findings. The primary tumors were well-defined soft-tissue masses centered in the roof of the nasal cavity eroding into the paranasal sinuses (11/11), the contralateral nasal cavity (4/11), the cranial cavity (5/11), and the fossa orbitalis (3/11). The tumor parenchyma were hypointensity on T1-weighted images, heterogeneous hyperintensity on T2-weighted images, and isodensity or slight hyperdensity on CT images with scattered necroses (4/11) and marginal cysts(4/11). Their enhancements were significant and inhomogeneous. Cervical lymph nodes metastases were observed in four patients (4/11), but no pathologically proved distant metastasis was observed. CONCLUSION Three types of direct intracranial extensions by ENB can be found on CT and MRI: cranio-orbital-nasal-communicating ENB, cranio-nasal-communicating ENB, and orbital-nasal-communicating ENB.

Abstract
Esthesioneuroblastoma is a rare malignancy arising from the olfactory epithelium. We present a case history of a 75-year-old man who presented with a Kadish stage C esthesioneuroblastoma and underwent craniofacial surgery and adjuvant radiotherapy. Two years later he was found to have diffuse subdural deposits with distant bone and nodal metastases, treated with further radiotherapy. The patient's condition subsequently deteriorated and he died. Given this unusual pattern of failure, we review the recent published studies regarding the natural history, treatment and outcome for this tumour.

Abstract
Esthesioneuroblastoma is a rare tumor for which the published literature does not provide an evidence-based consensus treatment approach. Multimodality therapy including a combination of surgery and radiation appears to provide the best disease-free and overall survival. Surgical resection should proceed through a craniofacial approach if possible. The role of chemotherapy in the initial treatment paradigm is less clear. Chemotherapy should not be used as single-modality therapy for initial treatment but may provide additional benefit when used in combination with radiation and surgery, particularly in advanced-stage disease. Combination chemotherapy should be considered as initial therapy for unresectable tumors and metastatic disease, and as salvage therapy in disease recurrence.
