Purpose:
The main aim of the present study is to analyze the behavior of squamous cell carcinoma (SCC) of maxillary gingiva, alveolus, and hard palate and to determine the utility of selective neck dissection in clinically N0 patients at early stages.
Material And Method:
Twenty-nine previously untreated patients with SCC of maxillary gingiva, alveolus, and hard palate were diagnosed and treated with at least a tumorectomy and selective neck dissection at HUVN and included in the study.
Results:
A total of 34.4% of patients (10/29) showed nodal involvement at postoperative histopathologic exam. Several pathologic features such as N involvement, N stage, T stage, and locoregional failure all have a negative impact on overall survival.
Discussion:
SCC of maxillary gingiva, alveolus, and hard palate shows an aggressive behavior that is comparable with other oral cavity cancers. A more aggressive treatment is thus required for improving locoregional control and overall survival. Supraomohyoid neck dissection may be useful in cT2N0M0.
