Abstract
OBJECTIVE: To determine demographic factors and clinicopathologic characteristics associated with survival in young patients (age <45 years) with early- (I-II) or late-stage (III-IV) oral tongue squamous cell carcinoma (OTSCC). STUDY DESIGN: Retrospective database review. SETTING: National Cancer Database. METHODS: A retrospective review of 3262 OTSCC cases in young patients between 2005 and 2014 was performed by using data from the National Cancer Database. Factors affecting 2-year survival in patients with early- and late-stage disease were evaluated via univariate and multivariate analyses. RESULTS: Overall, 1899 patients with early-stage OTSCC and 1363 with late-stage OTSCC were analyzed. In multivariate analysis of early-stage OTSCC, high tumor grade (hazard ratio, 2.08 [95% CI, 1.45-2.99]), local metastasis (2.85 [1.37-5.95]), and tumor size (1.04 [1.02-1.07]) were predictors of mortality. In late-stage OTSCC, African American race (2.79 [1.40-5.56]), positive surgical margins (1.77 [1.07-2.93]), local metastasis (2.20 [1.03-4.72]), distant metastasis (11.66 [2.10-64.73]), depth of invasion (1.03 [1.01-1.05]), and tumor size (1.01 [1.003-1.01]) were predictors of mortality. Subset analysis of clinical N0-stage tumors revealed that treatment with surgery alone was associated with improved survival (P < .001). CONCLUSION: Positive lymph nodes, high tumor grade, and larger tumor size were associated with increased mortality risk in early- and late-stage young OTSCC. More aggressive up-front treatment, including extirpative surgery and elective neck dissection, may be associated with improved outcomes and should be considered in early-stage cases with high-risk features.
