Abstract

Our goal was to evaluate the risk factors for regional recurrence in upper lip squamous cell carcinoma (SCC).

A total of 109 patients with upper lip SCC were retrospectively enrolled. Clinical and pathologic information was collected and analyzed.

Fifteen (13.8%) patients had a regional metastasis, 2 patients had parotid node metastasis, and no local or distant metastasis was noted. There was neck level I node metastasis in 15 (100%) patients. In multivariate analysis, invasion depth and degree of differentiation were significantly associated with regional metastasis. The 5- and 10-year disease-specific survival rate was 95.4% and 80.1%, respectively.

Invasion depth and degree of differentiation have reliable value for predicting regional metastasis.
