Has the management of pediatric mucoepidermoid carcinoma of the parotid gland changed?

Objectives/HypothesisStudy DesignTo examine the evolving changes in management of pediatric mucoepidermoid carcinoma of the parotid gland. Retrospective analysis of a large population database. MethodsResultsPediatric patients in the Surveillance, Epidemiology, and End Results database were included from 1973 to 2014 based on a diagnosis of mucoepidermoid carcinoma of the parotid gland using the International Classification of Diseases for Oncology, Third Edition codes: C07.9: parotid gland and 8430/3: mucoepidermoid carcinoma. Patients were included from ages 0 to 18 years. Patients were categorized into 5- or 6-year cohorts based on their year of diagnosis. Two-year and 5-year survival was calculated using actuarial or life-table analysis. One hundred sixty-nine pediatric cases were identified. Eighty of the 169 cases (47.4%) were diagnosed from 2005 to 2014. The number of cases increased steadily across cohorts over time since 1995. Pediatric patients tended to be diagnosed in adolescence (mean age: 13.4 years, range: 3.0-18.0 years). Most patients received surgical management as a part of their case (95.3% of total cohort). The 5-year disease-specific survival was>90% for each cohort. ConclusionsLevel of EvidenceThe age-adjusted incidence rate of pediatric mucoepidermoid carcinoma of the parotid gland remains low and is not greatly changing. This cancer is most likely diagnosed in adolescence affecting both male and female patients equally. Analysis of cases since 1973 revealed that most patients continue to receive surgical care. Survival for these pediatric patients continues to remain excellent. Healthcare providers should note these updates in pediatric mucoepidermoid carcinoma of the parotid gland as effective diagnosis and management continues to lead to good survival outcomes. 4 Laryngoscope, 128:2408-2414, 2018
