Overview
The predominant therapy for esthesioneuroblastoma is surgical resection followed by postoperative irradiation. Adjunctive radiation/chemotherapy may be required. The optimal therapy for esthesioneuroblastoma depends on the stage at diagnosis and regional or distant metastasis.
Medical Therapy
Surgery, radiation therapy (RT), and/or chemotherapy have all been used in the treatment of primary olfactory neuroblastomas.[1]. Observational studies have indicated that combining surgery and radiotherapy RT has resulted in prolonged disease-free and overall survival compared with either surgery or radiotherapy RT alone.
Surgery
Surgical resection of esthesioneuroblastoma originally used a transfacial approach. However, various multiple observational studies have found that a combined craniofacial approach improved the ability to achieve an en bloc resection and resulted in better local control of disease and improved survival compared with a transfacial approach.[2][3][1][4]
Radiation therapy
- In a number of series, radiation therapy alone has been used for the initial treatment of patients with olfactory neuroblastoma, but results have generally been less satisfactory than when radiation therapy (RT) is used in combination with surgery
- Standard techniques include 3-field technnique and a external megavoltage beam; an anterior port is combined with wedged lateral fields to provide a homogeneous dose distribution.
- The dose of radiotherapy varies from 5500-6500cGy. The majority of patients receive less than 6000 cGy. These doses are close to or exceed the maximum radiation dose recommended for sensitive structures such as the optic chiasma, optic nerve, brainstem, retina, and lens. Therefore, these patients are susceptible to cataract formation and glaucoma.
- A possible role of intensity-modulated radiotherapy, proton beam radiotherapy, and stereotactic radiation has been suggested. Several studies have reported that intensity-modulated radiotherapy can provide good tumor control with low rates of radiation-induced toxicity, in both adults and children. There are case reports which describe the use of CT-guided interstitial high-dose-rate brachytherapy.[5][1][6][7][8]
- Proton beam therapy may be especially important in children with developing soft tissue, bone, and neurological structures. Proton beam therapy is also being studied as a way to intensify dose and thus improve tumor control particularly in patients with unresectable disease or positive margins. However, there was greater neurological toxicity in patients receiving charged particle therapy compared with those receiving photon therapy.[9]
Surgery plus radiation therapy
A combined neurological anterior craniofacial and otolaryngologic resection followed by postoperative radiotherapy is the most widely used approach for patients with localized olfactory neuroblastoma. A minimum dose of at least 54 Gy in 30 treatments over six weeks is recommended for treatment of esthesioneuroblastoma.[10][11][12][3][1][13][14][15][16]
Adjuvant Chemotherapy
The role of chemotherapy, either before or after radiotherapy (RT) or surgery, is unclear. Many studies have used various chemotherapy regimens in an effort to improve outcomes. However, it is still unclear whether this actually improves results compared with a combined radiotherapy RT and craniofacial resection.[5][17][18][19][20][21]
Systemic disease
Because of the rarity of olfactory neuroblastomas, combined with the favorable prognosis following aggressive local regional therapy, there is only very limited experience for patients with disseminated disease. Cytotoxic chemotherapy appears to have activity in some patients, and newer molecularly targeted approaches may become an option as the biology of olfactory neuroblastomas is better understood.
- Cytotoxic chemotherapy — A variety of chemotherapy agents have been evaluated in various case series. These reports have included a mixture of patients with locoregional disease and disseminated disease where chemotherapy was used alone or in combination with radiotherapy RT and/or surgery. Cisplatin-based combination regimens (particularly cisplatin and etoposide) have often been chosen, because of their activity in patients with head and neck squamous cell cancer (SCC) or related neuroendocrine type tumors. Non-platinum combinations, such as irinotecan plus docetaxel or doxorubicin, vincristine, and ifosfamide, may also be active. Generally, responses in patients with disseminated disease have been of short duration.
- Molecularly targeted therapy — An understanding of the molecular pathogenesis of esthesioneuroblastomas may lead to the use of targeted therapies in patients with advanced disease:
