Division of Neurosurgery, Toronto Western Hospital, University Health Network, Toronto, ON, Canada.

During the last two decades evolution of the endoscopic endonasal approaches (EEA) has offered the option of minimally invasive techniques in the management of esthesioneuroblastomas (ENB), either as endoscope assisted cranial resection or as pure endoscopic procedures. This study presents the use of pure EEA in the management of ENB in our center, along with a literature review. We retrospectively reviewed the clinical, radiology and pathology records of patients with ENB treated during the period July 2006 to January 2016. Read More

Cell Rep 2018 Oct;25(3):811-821.e5

Department of Medical Oncology, Groupe Hospitalier Pitié-Salpêtrière, Assistance Publique Hôpitaux de Paris, Sorbonnes-Universités, University Pierre and Marie Curie, Paris, France; Department of Hematology and Medical Oncology, CHRU Strasbourg, Hôpital Hautepierre, Strasbourg, France; Institut Génomique et de Biologie Moléculaire et Cellulaire (IGBMC), Illkirch-Graffenstaden, France. Electronic address:

Esthesioneuroblastoma (ENB) is a rare cancer of the olfactory mucosa, with no established molecular stratification to date. We report similarities of ENB with tumors arising in the neural crest and perform integrative analysis of these tumors. We propose a molecular-based subtype classification of ENB as basal or neural, both of which have distinct pathological, transcriptomic, proteomic, and immune features. Read More

Successful Use of Extracorporeal Membrane Oxygenation for Respiratory Failure After Cranial Surgery.

World Neurosurg 2018 Dec 24;120:426-429. Epub 2018 Sep 24.

Department of Neurology & Neurosurgery, University of Miami Health System, Miami, Florida, USA. Electronic address:

Background: The use of extracorporeal membrane oxygenation (ECMO) for cardiopulmonary support is indicated for refractory respiratory failure but carries a high morbidity and mortality in the neurosurgical setting due to associated risks of intracranial hemorrhage.

Case Description: We describe the case of a 62-year-old man who underwent craniotomy for resection of an esthesioneuroblastoma involving the anterior skull base and extending intracranially, through the cribriform plate into the right epidural space. He developed refractory hypoxemic and hypercapnic respiratory failure and circulatory shock in the immediate postoperative period. Read More

Dural Invasion Predicts the Laterality and Development of Neck Metastases in Esthesioneuroblastoma.

J Neurol Surg B Skull Base 2018 Oct 22;79(5):495-500. Epub 2018 Feb 22.

Department of Otolaryngology-Head and Neck Surgery, Mayo Clinic, Rochester, Minnesota, United States.

 Neck metastases in patients with esthesioneuroblastoma (ENB) constitute the most significant predictor of poor long-term survival. Recently, researchers discovered the existence of dural lymphatic channels that drain to the cervical lymph nodes. From this physiologic basis, we hypothesized that patients with ENB who develop dural invasion (DI) would exhibit a proclivity for neck metastases. Read More

Esthesioneuroblastoma and Olfactory Preservation: Is it Reasonable to Attempt Smell Preservation?

J Neurol Surg B Skull Base 2018 Apr 28;79(2):184-188. Epub 2017 Aug 28.

Department of Neurosurgery, Mayo Clinic, Rochester, Minnesota, United States.

 Olfactory preservation after resection of esthesioneuroblastoma (ENB) has been reported, however, the ability to predict tumor involvement of the olfactory system is critical to this surgical strategy. This study aims to answer the question: Can a surgeon predict, based on preoperative imaging, whether there is unilateral involvement of the olfactory system allowing for safe attempt of olfactory preservation?  This is a retrospective review of post-resection ENB meeting inclusion criteria of having bilateral olfactory tracts and bulbs submitted at the time of primary resection for pathologic margins. Five board-certified skull base surgeons blinded to the pathology individually reviewed the preoperative MRI scans to predict degree of tumor involvement. Read More

Head Neck Pathol 2018 Mar 9;12(1):22-30. Epub 2018 Feb 9.

Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, TX, 77030, USA.

Sinonasal tumors with neuroendocrine differentiation form a group of rare heterogeneous neoplasms of neuroectodermal and epithelial origin, consisting of olfactory neuroblastomas and neuroendocrine carcinomas. Because the natural history and biological behavior of this group of tumors vary, the morphological diagnosis coupled with grading/staging is important for prognostication, and the approach to treatment and rehabilitation is multidisciplinary. The identification of molecular abnormalities underlying these tumors is critical to the development of specific targeted therapies and the design of clinical trials. Read More

Neuroendocrine neoplasms (NENs) are infrequent in sensory organs. There are well-differentiated neuroendocrine neoplasms that should be classified as neuroendocrine tumors, in analogy to their gastrointestinal counterparts, however the nomenclature is inconsistent. The best defined entities are neuroendocrine tumors in the middle ear and ectopic pituitary adenoma in the sphenoid region. Read More

Esthesioneuroblastoma (ENB) is an uncommon neuroendocrine tumor originating from the olfactory neuroepithelium and accounts for 3-6% of all intranasal tumors [¹]. ENBs can be locally aggressive and cause invasion and destruction of surrounding structures. Histological grading and clinical stage at presentation are highly predictive of survival and especially presence of lymph node and distant metastases are determining prognostic factors [²,³,⁴,⁵].
