Primary lung mucoepidermoid carcinoma: analysis of prognostic factors using surveillance, epidemiology and end results program.

Abstract

INTRODUCTION: Mucoepidermoid carcinoma (MEC) primarily occurs in salivary glands, but can also arise in other organs; however, the impact of primary location on patient prognosis is largely unknown.

METHODS: Using Surveillance, Epidemiology and End Results Program (SEER) data we investigated whether the clinical and prognostic features of MEC differed among multiple organ sites. The SEER-18 dataset from 18 cancer registries in the US between 1972 and 2012 was chosen. The common organ sites with 100 or more cases were further analyzed. Survival analysis included Log-rank tests of Kaplan-Meier curves and univariate/multivariate proportional hazard analysis.

RESULTS: A total of 7,191 MEC cases with survival data were identified in the SEER data. Major salivary gland (MSG) was the primary site in 52.9% of cases, followed by gum and other mouth (23.6%), lung (5.9%), tongue (3.4%) and others. Compared to MSG-MEC, primary lung MEC had significantly more patients with age

CONCLUSIONS: This study suggests that there is a major difference in prognosis of MEC among primary sites. Primary lung MEC might have poor prognosis over MSG-MEC.
