A retrospective study was conducted to evaluate the clinical outcomes of 25 patients with mandibular gingival squamous cell carcinoma in our hospital between April 2012 and January 2018. All patients underwent surgical resection. Twenty-one patients had microscopically involved resection margins, extranodal extension, pT4 primary, pN2 or pN3 nodal disease. Ten patients underwent adjuvant postoperative therapy, but 11 patients did not. The 5-year overall survival rates were 63％ in all patients, 100％ in pN0 and 27％ in pN＋. Pathological node metastasis was the most significant predictive factor for 5-year overall survival （p＝0.0003）.
