Abstract | BACKGROUND AND OBJECTIVES: METHODS: The pattern of lymph node spread was analyzed in 64 patients with SMG carcinoma treated from January 1994 to January 2009. Disease-free survival (DFS), overall survival (OS), and distant metastasis-free survival (DMFS) were calculated, and the clinicopathological factors associated with each were analyzed. RESULTS: Positive pathological lymph nodes were detected in 31 (48.4%) patients and was found to correlate significantly with histologic grade (P<0.001) on univariate analysis. Eight patients (19.5%) had occult cervical metastases. The 5-year DFS, OS, and DMFS rates were 46.8, 56.2, and 58.5%, respectively, and 23 patients (35.9%) experienced systemic failure. Multivariate analyses revealed that T-classification (P=0.043) and N-classification (P=0.006) were significantly independent predictors of DFS, whereas only N-classification (P=0.049) was significantly associated with DMFS. CONCLUSIONS:
