Kuan EC, et al. - A total of 381 cases were examined to study the incidence and trends of esthesioneuroblastoma-associated cervical nodal metastases [using the Surveillance, Epidemiology, and End Results (SEER) database]. researchers observed 8.7%, the overall cervical nodal metastasis rate, and Level II metastases as the most common (6.6%) one. Correlation of male gender and higher tumor grade with the presence of level II metastases was also reported. they found that primary tumor site and the presence of nodal metastases were not associated with each other. Poorer overall and disease-specific survival were significantly predicted with the presence of nodal disease.
