چکیده انگلیسی


• Overall survival at 5 and 10 years is 77% and 56%.
• Regional metastasis (45.1% of cases) does not significantly impact survival.
• Radiation and surgery is recommended over surgery alone.
• Age, stage, and therapy are significant predictors of survival.

SummaryIntroductionLymphoepithelial carcinoma (LEC) of the salivary glands is extremely rare worldwide, with studies limited to small case reports and case series from endemic areas (Southern China, Arctic Inuits) and strong association to Epstein Barr Virus (EBV). Studies on non-endemic regions are even more limited given the reality of only sporadic cases in these areas. Using the National Cancer Database (NCDB), we present the largest study on salivary LEC from a non-endemic region, the United States.MethodsA retrospective review of the NCDB from 1998–2012 for LEC of the major salivary glands was performed. Demographic and clinical variables were extracted for analysis. Multivariate COX regression was used to assess predictors of survival.ResultsTwo hundred and thirty-eight cases were identified (0.66% of all salivary cancers). Median age at diagnosis was 62 with peak incidence in ages 50–70. Most patients were Caucasian (81.2%), without gender preference. Regional metastasis was common (45.1%) and did not significantly impact survival. Distant metastasis was rare (2%). Overall survival (OS) at 5- and 10 years was 77% and 56%. Surgery and radiotherapy significantly showed better survival outcomes than surgery alone (p < 0.001). Age >62, advanced stage, and dual modality therapy were significant predictors of survival in multivariate analysis.ConclusionLymphoepithelial carcinoma in the US mostly affects an older, Caucasian demographic. Regional metastasis is common and survival is fair at 5- and 10 years. Surgery and radiation are recommended for early and advanced disease stages. Age, stage, and therapy are significant predictors of survival outcomes.
