Abstract:Objectives: Determine the incidence and factors influencing neck disease, at presentation and delayed, in patients with olfactory neuroblastoma. Methods: Patients with a histological diagnosis of olfactory neuroblastoma that were treated across 6 tertiary hospitals were included. Treatment modalities to primary site and neck included radiotherapy, surgery, and combinations. The status of cervical lymph node metastases at presentation and at last follow-up was defined. Disease-free survival (DFS) was calculated… Show more
“…Tajudeen et al previously reported on the significance of advanced tumor grade as a predictor of survival in ENB using the SEER database . Another multi‐institutional study by Nalavenkata et al found a similar trend between neck metastasis and tumor grade, with those patients presenting with neck disease initially having higher tumor grade overall . Taken together, these findings suggest that there may be a potential role in stratifying long‐term surveillance of ENB patients by initial tumor grade on biopsy or resection because these patients may be at more risk to develop regional recurrence.…”

“…The combination of disease rarity and nonspecific symptomatology delays initial diagnosis and frequently leads to patient presentation after the tumor has already invaded local structures. This presentation contributes to nodal spread of ONBs, with the preponderance of the literature reporting overall neck involvement in the range of 15% to 25% of patients …”
“…This neoplasm is locally aggressive and commonly involves the nasal cavity, paranasal sinuses, and cribriform plate; there also may be extension into the cranial and orbital compartments. Many patients develop neck and distant metastasis during the course of their disease …”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
