title: Good tumor control and survivals of squamous cell carcinoma of buccal mucosa treated with radical surgery with or without neck dissection in Taiwan.
abstract: The aim was to analyze the survival and prognostic factors in 232 patients with squamous cell carcinoma of the buccal mucosa (BSCC) treated with radical surgery with or without neck dissection (ND). The 5-year survivals for local, locoregional control, overall, disease-free, and disease-specific were demonstrated. Pathologic nodal status was the independent risk factor for local and locoregional control. Both pathologic nodal status and cell differentiation were the significant prognostic factors of disease-free survival. For cT1N0, 11.1% had neck metastases. All were tumor depth of > or =6 mm. Our result showed a relatively better tumor control and survivals in BSCC with radical surgery with or without ND. The possible reason may be due to the benefit from widely surgical resection with ND and post-operative radiotherapy or concurrent chemoradiotherapy in those with risk factors. In treating early cT1N0, we suggest that elective ND is indicated only when tumor depth > or =6 mm.
