Purpose: Submandibular gland cancer is relatively rare. The purpose of this study was to estimate 5-year overall survival (OS) and disease-free survival (DFS) and to identify prognostic factors associated with OS and DFS for submandibular cancer.Materials and Methods: The authors implemented a retrospective cohort study and enrolled a sample of patients with submandibular gland cancer. The predictor variables were age, gender, tumor stage, nodal stage, margin status, and extracapsular spread. The outcome variables were 5-year OS and 5-year DFS. Kaplan-Meier methods were used to estimate survival and Cox hazards models were used to identify prognostic variables.Results: The sample was composed of 52 patients with submandibular gland cancer (mean age, 47.4 yr; 51.9% men). The median follow-up was 81 months (range, 11 to 159 months). The 5-year OS and DFS rates were 76.9 and 67.3%, respectively. Fixed mass, positive neck node, and positive margin status were relevant predictors of OS and DFS. Nodal stage was the relevant independent predictor affecting the disease outcome of submandibular gland cancer.Conclusion: These results identified several important prognostic factors associated with survival rate in patients with submandibular gland cancer. These prognostic variables include symptoms at presentation, pathologic nodal status, and margin status. These outcomes suggest that heightening vigilance of clinical characteristics for this disease might provide the impetus for improving the survival rate.
