Abstract
BACKGROUND: Treatment for early-stage tongue squamous cell carcinoma (SCC) is usually surgery alone. There is ambiguity regarding the impact of minor adverse features (MAFs) on outcome and the role of postoperative radiotherapy (PORT) in tongue SCC.
METHODS: A retrospective analysis was performed on 48 patients diagnosed with tongue SCC treated in our center. Patients with MAFs received adjuvant PORT. Disease outcome in patients with MAFs, and the effect of PORT were analyzed using the Kaplan-Meier method and log-rank test.
RESULTS: Thirty-one patients had T1 and 17 had T2 disease. PORT was given to 7 patients with MAFs. Mean follow-up time was 70 months. The 2-year overall survival (OS) rate was 86%. Perineural invasion had a significant impact on disease-free survival (DFS; p =.05). There was an improved DFS in patients with MAFs treated with PORT (p =.01).
CONCLUSION: MAFs may have an impact on outcome in tongue SCC, and PORT can improve disease outcome in these patients. © 2016 Wiley Periodicals, Inc. Head Neck, 2016.
