Seventeen patients with olfactory neuroblastoma seen at the Massachusetts General Hospital and Massachusetts Eye and Ear Infirmary from 1941 to 1971 are presented. Data on age, sex, symptoms, physical, and roentgenographic findings, and therapeutic results are evaluated. A system of pretherapy staging is proposed in which for Group A, the tumor is limited to the nasal cavity; in group B, the tumor is localized to the nasal acvity and paranasal sinuses; and in group C, the tumor extends beyond the nasal cavity and paranasal sinuses.
Olfactory neuroblastoma
is a radioresponsive, and, to a limited extent, radiocurable tumor and varies in aggressiveness. Of 17 patients in this series, 13 or 76% were alive without disease following treatment by surgery, irradiation, and combination of these two methods. Uncontrolled primary lesions with or without
metastases
accounted for all therapeutic failures. A treatment policy for this disease is presented.

Olfactory neuroblastoma
, a nerve tumour arising in the olfactory mucosa, is a relatively easy diagnosis in the case of a mass centered around the cribriform plate. It is more difficult to diagnose in its exceptional ectopic forms (maxillary sinus) in the absence of any cytological and histochemical arguments (fibrils, olfactory rosettes). Its local malignancy is variable with a 42% 5-year survival for stage C and
metastases
in 30% of cases (principally cervical nodes, bone and liver). The role of imaging is to define the criteria of a mass syndrome and to perform the preoperative staging in a case of apparently simple sinus obstruction.

Esthesioneuroblastoma
(ENB) is a rare malignant neoplasm arising from the cribriform olfactory epithelium. Its aggressive biologic behavior is characterized by inapparent submucosal spread, local recurrence, atypical distant
metastases
, and poor long-term prognosis. Historically, the suspicion of neck metastasis has not been associated with ENB. A retrospective review of all ENB patients treated at the University of North Carolina Hospitals since 1972 has revealed an unusually high incidence of cervical
metastases
(four of four patients). This prompted a review of the ENB surgical literature. All English-literature series published since the widespread use of craniofacial surgery with accruals of eight or more patients were examined for reports of neck metastasis. Although the cumulative cervical metastatic rate reached 27% (55 of 207 patients), most authors failed to recognize the potential risk of cervical metastasis in ENB. Furthermore, in patients suffering from Kadish stage C disease, the cervical metastatic rate climbed to 44% (25 of 57 Kadish stage C patients). This further emphasizes the importance of the neck as a high-risk metastatic site. These findings suggest that cervical
metastases
may be an important consideration in the evaluation and treatment of patients suffering from ENB. Strategies for evaluation and management of the neck are discussed.

The authors report on an 83-years-old woman with
esthesioneuroblastoma
(ENB). The first clinical manifestation was an invasion of the suborbital and orbital region. ENB are local destructive tumours which seldom
metastasize
. Complete surgical excision, supplemented by irradiation therapy offers the highest cure rate. Relapses should be treated with individualized afterloading radiotherapy.

Esthesioneuroblastoma
is a rare tumor in children, and the correct diagnosis may be difficult, as is demonstrated in this case report. A 5-year-old girl was diagnosed with this tumor, which was incurable and behaved like a neuroblastoma, sending
metastases
to the bone marrow and invading the cranium and the spinal canal.

We report a 16-year-old boy with
esthesioneuroblastoma
that presented with a unilateral tumor extending to the maxillary sinus and periorbital region. Despite initial therapy with gross resection, 5,682 cGy to the tumor bed and chemotherapy, the patient subsequently had a rapid local recurrence with distant
metastases
. Immunocytochemical, ultrastructural, cytogenetic, and molecular techniques were performed to determine if this tumor was biologically similar to childhood neuroblastoma. Urinary excretion of vanillylmandelic acid (VMA) and homovanillic acid (HVA) were markedly elevated. Chromogranin and neuron specific enolase immunostaining of tumor cells was positive, as seen in neuroblastoma. Electron microscopic studies showed cells that were closely packed and connected by occasional cell junctions. The cell cytoplasm contained moderate amounts of filaments and microtubules. Numerous electron dense granules were observed; however, these granules lacked distinct nucleoids and generally reacted strongly for acid phosphatase, indicating a lysosomal rather than a secretory function. Tumor cells contained near-pseudotetraploid chromosomes, with all chromosomes represented at least three times, and chromosome 5 was present in multiples of eight. Clonal structural abnormalities included 2q+ and 5q+ and multiple double minutes. Northern blot analysis revealed both c-myc and N-myc expression; however, N-myc amplification was not demonstrated, and c-myc expression appeared increased, unlike cases of rapidly progressive neuroblastoma. These results suggest that despite biologic similarities to neuroblastoma in catecholamine excretion and some ultrastructural features, molecular genetic abnormalities differ in this comparatively aggressive case of estesioneuroblastoma.

Esthesioneuroblastoma
is a rare epithelial tumor of the nasal olfactory mucosa. Its clinical course is characterized by indolent growth and persistent local recurrence and occasional distant
metastases
despite attempts at cure. Our report documents the response of a patient to a cisplatin-based drug combination and reviews the English-language literature of 25 patients treated with chemotherapy. We conclude that this tumor is sensitive to several different combinations and suggest guidelines for the use of chemotherapy in advanced or metastatic
esthesioneuroblastoma
.

At the Radiological Hospital of the Heidelberg University, one patient with a local recurrence of an
esthesioneuroblastoma
situated on the left-hand side of the skull base was treated between February 11 and March 18, 1986, by an afterloading contact therapy with curative intent. After preceding surgery and percutaneous radiotherapy, repeated local recurrences and locoregional lymph node
metastases
had occurred. The contact therapy was performed after adjusting an individual face mask in which the afterloading probe was placed and brought into its position in the tumor region. The irradiation scheme was based on the transformation of the source coordinates form the stereoscopic X-ray localization system into the coordinate system of the computed tomogram by means of X-ray tight reference points. The irradiation planning by computed tomography allows to optimize the arrangement of sources within the tumor region. The principles of the method as well as the treatment result are presented.

Olfactory neuroblastoma
is a rare malignant tumor arising from the nasal cavity. From 1982 to 1987 fourteen cases had been treated in this hospital. The average age was 34 years with a range from 15 to 65 years, male to female ratio was 1:1. At the time of diagnosis, 3 tumors were of kadish stage A-involvement of the nasal cavity only, 5 of stage B-involvement of the nasal cavity and one or more paranasal sinuses, and six of stage C-extension beyond the nasal cavity, including the orbit, base of skull or intracranial cavity, or metastasis to cervical nodes or distant sites. All were treated with radiation therapy and 7 also by surgery. The three and five-year survival rates were 50% and 30% respectively. Seven patients died, six because of distant
metastases
within one year. It shows that the disease is aggressive from the beginning, and tends to
metastasize
early. A treatment regimen for prophylactic cervical node irradiation combining chemotherapy is proposed.

Esthesioneuroblastoma
is an uncommon tumor arising from the olfactory epithelium of the nasal cavity. Since most cases present clinically with non-specific findings such as unilateral nasal obstruction and intermittent epistaxis,
esthesioneuroblastoma
is often mistaken for other diseases of the nasal cavity. Histological confirmation of the disease can also be difficult. The aggressive nature of
esthesioneuroblastoma
is evidenced by frequent local recurrences and occasional distant
metastases
--further complicating the management of this tumor. The otolaryngologist should possess a high index of suspicion for this rare, but devastating malignancy. Guidelines for the evaluation and treatment are presented.
