Abstract
BACKGROUND For olfactory neuroblastoma (ONB), the combination of surgical tumor resection and radiation therapy (RT) has been considered the "gold standard" in treatment protocols intended to cure. OBJECTIVE To summarize evidence on the treatment of ONB using surgery alone. METHODS A retrospective institutional case series, a systematic review of the literature, and an individual patient data (IPD) meta-analysis on only surgically treated ONB patients. RESULTS At our institution, a total of 10 patients were treated through surgery alone and remained alive and free of disease at last follow-up. The IPD meta-analysis on 128 patients revealed a disease-free survival (DFS) and overall survival (OS) of 67.7% and 75.4% at 5 years and 57.1% and 71.9% at 10 years, respectively. Univariate analysis showed that Kadish stage C/D and Hyams grading III//IV significantly affected OS (P = 0.000 and P = 0.000) and DFS (P = 0.000 and P = 0.002). For low-risk patients, the DFS was 80.6% at 5 years and 67.8% at 10 years, respectively. CONCLUSIONS Surgery alone is an equivalent alternative to combined treatment in carefully selected low-risk ONB patients with better outcome measures than previously reported.

Abstract
Esthesioneuroblastoma has a local recurrence rate of ∼30%, but no standard regimen for salvage of local recurrence has been established. We report data from 678 patients from series published since 1990, with a risk reduction analysis of salvage with surgery, radiation, or combined surgery and radiation therapy. We found a 28.5% rate of local recurrence after treatment, and a 42.6% rate of successful salvage with surgery, radiation, or combined treatment. The odds ratio for successful salvage, defined as disease-free survival for at least 1 year, was not significantly different for combined surgery and radiation versus surgery alone or radiation alone or for surgery alone versus radiation alone. The salvage odds ratio for combined surgery and radiation therapy versus radiation therapy alone, 3.5, approached, but did not reach statistical significance. This study reveals a reasonable rate of successful salvage of local esthesioneuroblastoma recurrence using surgery, radiation, or combined surgery and radiation.

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
Esthesioneuroblastoma (ENB) differs from adrenal neuroblastomas in its histopathologic and biologic characteristics. Hyams grading and Kadish staging have shown correlation with survival. Scant data are available on proliferation indices and prognosis. We retrospectively reviewed the clinicopathologic characteristics of ENB. Both Kadish and UCLA staging systems were used. Hyams grading was simplified into low and high grade. DNA topoisomerase II alpha labeling index (T2alpha LI) was obtained in 8 cases using immunohistochemistry. Of the 19 cases studied, 14 were males and 5 females. Age range was 2 to 62 years (average 27 years). The mass primarily involved the nose in 12 (63%) and paranasal sinuses in 7 cases (37%). Patients presented with nose block in 19 (100%), epistaxis in 10 (53%), proptosis in 9 (47%) and loss of vision in 6 cases (32%). Bony involvement was seen in 7 cases (37%), and intracranial spread in one case (5%). Thirteen (68%) were low-grade tumors and 6 were (32%) high-grade. There was no statistically significant difference between the low- and high-grade ENB in age (years) (p=0.2882), duration of symptoms (months) (p=0.5636), and either in the Kadish (p=0.5456) or the UCLA staging system (p=0.7771). The difference in DNA topoisomerase alpha labeling index between the low- and highgrade ENB (medians: 10.4 and 22.3, respectively) was not statistically significant (p=0.0714), but it was suggestive of a positive association. The results of this study should be interpreted with caution, because of the limited sample size. Three cases recurred locally, one each stage A, B and C, but all low-grade. This preliminary study suggests the need to combine a simplified histologic grading with accurate staging in a reasonable attempt to assess local progression in esthesioneuroblastoma. Larger studies may clarify the role of T2alpha LI in improving histologic grading.

Abstract
AbstractOlfactory neuroblastoma is an uncommon tumour arising in the nasal cavity or paranasal sinuses. We report the management of nine cases treated with external beam radiotherapy subsequent to sureery, either attempted definitive removal or biopsy only. Recent refinements in pathologicalevaluation of these tumours are discussed. Seven cases were deemed classical olfactory neuroblastoma whilst two were classified as neuroendocrine carcinoma. The clinical features, radirap technique and variable natural history are presented. Seven of eight patients treatecall were controlled locally, with a minimumfollow-up of two years. Three patients developedcervica lymph node disease and three patients died of systemic metastatic disease. Suggestios are made as to which patients should have en-bloc resection rather than definitive radiotherapy.

Abstract
OBJECTIVE Olfactory neuroblastomas are very aggressive tumors with a high locoregional recurrence rate and distant metastasis. Surgical treatment, including craniofacial resection, has been the main treatment modality, but treatment outcomes of concurrent chemoradiotherapy remain unclear. We present our experiences regarding the treatment outcome of patients with advanced olfactory neuroblastoma undergoing surgical treatment and concurrent chemoradiotherapy. METHODS We retrospectively analyzed 16 patients treated for advanced olfactory neuroblastoma within the past 10 years. RESULTS The disease-free 5-year survival rate of the patients (n = 10) who underwent surgical treatment was 68%. The survival rate for patients (n = 6) who received concurrent chemoradiotherapy was 42%. The difference in the survival rate was not statistically significant, and no difference in the recurrence rate between the two groups. In the group having surgical treatment, post-operative radiotherapy and salvage therapy were important to increase the survival rate. In the group having concurrent chemoradiotherapy, no patient experienced primary tumor progression. CONCLUSION Complete surgical resection, including craniofacial resection (CFR), and post-operative radiotherapy seem to be essential in the treatment of advanced olfactory neuroblastoma. However, concurrent chemoradiotherapy may be another primary treatment modality.

Abstract
INTRODUCTION Esthesioneuroblastoma is an uncommon malignancy of the olfactory neuroepithelium. The best treatment has yet to be defined. The purpose of this study is to analyze the tumors's behaviour to choose the ideal treatment, the therapeutic strategy and the patterns of failure. MATERIALS AND METHODS We carry out a revision of the series published between 1994 to 2004. In these series, we found 39 papers with 713 patients. DISCUSSION CONCLUSIONS In this review the 5-years survival rate is 51.2%. Through the analysis of 583 partients found in 34 publications, surgery (alone or combined) is the treatment most used (78%). The commonly management is surgical in combination with radiotherapy (47%).

Abstract
OBJECTIVE A retrospective review of all diagnosed cases of esthesioneuroblastoma registered in Denmark between 1978 and 2000 was carried out in order to obtain epidemiological data and optimize national treatment guidelines. MATERIAL AND METHODS Forty cases were verified histologically and included in the analysis Epidemiological and histopathological data were evaluated in relation to the clinical outcome. RESULTS The 40 cases represent an incidence rate of 0.4 cases/million inhabitants per year. Eight (20%) patients were classified as Kadish stage A, 13 (32.5%) as stage B and 19 (47.5%) as stage C. The histopathological findings were classified according to the grading system of Hyams The median follow-up time was 2.3 years (range 0.3-11.1 years). The 5-year crude survival rate was 61%, with a median survival of 3.1 years (range 0.3-19.2 years). The 5-year disease-free survival rate was 50%, with a median survival of 1.7 years (range 0-19.2 years). Only 3 (7%) patients had positive cervical lymph nodes at presentation. A nationwide consensus regarding treatment was seen in patients classified as Kadish stages A and B. The longest duration before the first recurrence of esthesioneuroblastoma was 5(1/2) years. CONCLUSIONS The following therapeutic guidelines are suggested: Kadish stage A patients, surgical tumour resection and radiotherapy; Kadish stage B, surgical tumour resection and radiotherapy; Kadish stage C, surgical tumour resection via a craniofacial resection and radiotherapy combined with chemotherapy. Long-term follow-up of esthesioneuroblastoma patients is mandatory.

Abstract
Esthesioneuroblastoma (olfactory neuroblastoma) is a rare tumor of the olfactory epithelium. Approximately 1,000 cases have been described in the literature since the original description in 1924. It occurs in older individuals and is rare in children. The authors describe the clinicopathologic presentation in a series of five children treated with neoadjuvant/adjuvant chemotherapy and review the English literature for previously described patients younger than 18 years to assess clinical presentation, mode of treatment, and outcome in this age group.

Abstract
Esthesioneuroblastoma is a rare tumor of neural crest origin that arises in the nasal cavity. There is still no consensus on the optimal treatment for this neoplasm, and the literature contains very few accounts of endoscopic excision in these cases. We described a case report of 12-year-old girl with esthesioneuroblastoma that was confined to the nasal cavity and paranasal sinuses, with no orbital or intracranial extension. The tumor was removed via intranasal endoscopic approach and radiotherapy was administered postoperatively. The patient is currently being followed, and there has been no recurrence in 24 months after surgery.

Abstract
Our objective was to review recent developments in diagnosis, staging, and treatment of esthesioneuroblastoma (ENB). A meta-analysis of publications between 1990 and 2000 was carried out, and studies were classified according to their main subject: origin/aetiology of ENB, histopathological diagnosis, and treatment. Data so far point to the basal progenitor cells of the olfactory epithelium as the origin of ENB. Histopathological diagnosis remains difficult and is based on results of antigen expression detected through a panel of antibodies by immunohistochemistry. RT-PCR of HASH expression could be a specific marker of ENB. Overall and disease-free survival at 5 years averaged 45% (SD 22) and 41% (SD 21) in the studies included in the meta-analysis. Survival in Hyams' grades I-II was 56% (SD 20) compared with 25% (SD 20) in grades III-IV (odds ratio 6.2). In patients with metastases in cervical lymph nodes (on average 5% of the total) survival was 29%, compared with 64% for patients with N0 disease (odds ratio 5.1). Survival according to treatment modalities was 65% for surgery plus radiotherapy, 51% for radiotherapy and chemotherapy, 48% for surgery, 47% for surgery plus radiotherapy and chemotherapy, and 37% for radiotherapy alone. The histopathological grading according to Hyams and the presence of cervical lymph-node metastases emerged as prognostic factors. A combination of surgery and radiotherapy seems to be the optimum approach to treatment. The exact role of chemotherapy in treatment protocols is still unclear. The role of elective neck dissection is unclear.

Abstract
OBJECTIVES Hyams proposed a histological grading system for esthesioneuroblastoma in which grade I tumors have an excellent prognosis and grade IV tumors are uniformly fatal. The Hyams grading system predated advanced craniofacial techniques, extensive use of immunohistochemistry, and the recognition of sinonasal undifferentiated carcinoma (SNUC) as a distinct entity. Therefore we aimed to determine whether Hyams classification is useful in predicting outcome for esthesioneuroblastoma and SNUC. STUDY DESIGN A retrospective review of cases from 1970 to 1999. METHODS Twenty-six patients (12 with esthesioneuroblastoma and 14 with SNUC) were reviewed. The Kadish clinical stage was determined, and histopathological slides were reviewed and graded using the Hyams system. RESULTS Kadish staging was available for 26 patients (2 patients with stage A tumors; 7 with stage B; and 17 with stage C). Of the 8 evaluable patients with Kadish stage A or B tumors, 6 remained disease free for more than 2 years compared with only 5 of the 17 Kadish stage C tumors. Slides were available for Hyams grading in 21 patients (2 patients with grade I tumors; 4 with grade II; 4 with grade III; and 11 with grade IV). Of the 6 patients with Hyams grade I or II tumors, 4 remained disease free for more than 2 years compared with only 4 of the 15 patients with Hyams grade III or IV tumors. Of note, three patients with Kadish stage C tumors (two with esthesioneuroblastoma, one with SNUC) and two patients with Hyams grade IV tumors (one with esthesioneuroblastoma and one with SNUC) survived for more than 5 years. CONCLUSIONS Both the Hyams grading system and the Kadish staging system can be used as independent predictors of outcome. Although limited by small numbers, the results of this study demonstrate that patients with either advanced clinical stage or pathological grade of esthesioneuroblastoma or SNUC have poor prognosis, but that long-term survival is possible in these patients if aggressive treatment is used.

Abstract
OBJECTIVES To describe a new treatment modality of olfactory neuroblastoma consisting of endoscopic nasal and paranasal sinus surgery and stereotactic radiosurgery. STUDY DESIGN Retrospective review of three patients suffering from olfactory neuroblastoma. METHODS Review of the charts, the computed tomography, and magnetic resonance imaging scans, the operation reports, radiosurgical data, and follow-up. RESULTS All three patients remained free of disease with excellent quality of life in respective follow-up periods of 71, 50, and 39 months. CONCLUSION The combination of two minimally invasive therapies, endoscopic sinus surgery and stereotactic radiosurgery, provide a reliable new approach to the treatment of a series of olfactory neuroblastomas that offers excellent quality of life, less injury to the patient, fewer side-effects, and fewer long-term effects than other treatment strategies.

Abstract
OBJECTIVE Esthesioneuroblastoma (olfactory neuroblastoma) is a rare neuroendocrine tumor that arises in the upper nasal cavity from the olfactory epithelium. Little information is available regarding the treatment of these tumors with chemotherapy in the advanced setting. A retrospective review of patients with recurrent esthesioneuroblastoma treated with chemotherapy between 1970 and 1995 at the Mayo Clinic was undertaken to gain more information regarding the efficacy of chemotherapy treatment for these patients. METHODS Ten patients were identified using a computerized data base available at this institution. The clinical and pathological materials, when available, were reviewed, and each tumor reviewed was assigned a Hyams' grade. RESULTS There were six men and four women, ranging in age from 22 to 74 years, all of whom had assessable Kadish Stage C disease at the time of chemotherapy treatment. The chemotherapy regimens and clinical follow-up varied during this 25-year time span. The only tumor regression resultant from chemotherapy was observed in patients with high-grade tumors. Two of four patients with high-grade tumors obtained regression from first-line, platinum-based chemotherapy, with a mean duration of regression of 9.3 months (range, 2-13 mo). Survival time from initial diagnosis was 139.5 months (range, 83-168 mo) in patients with low-grade tumors and 32.2 months (range, 5-84 mo) in patients with high-grade tumors. Survival from initial chemotherapy treatment was 44.5 months (range, 3-130 mo) in patients with low-grade tumors and 26.5 months (range, 2-67 mo) in patients with high-grade tumors. CONCLUSION Hyams' grading of esthesioneuroblastoma tumors seems to be important in predicting response to chemotherapy. Despite sensitivity to platinum-based chemotherapy, patients with high-grade tumors in this series had a much more aggressive course than did those with lower-grade tumors. This series suggests that cisplatin-based chemotherapy is active in advanced, high-grade esthesioneuroblastoma and is a reasonable choice in the systemic treatment of these patients.
