Purpose The aim of this study is to evaluate prognosis and prognostic factors affecting oncological outcome. Methods Records of the subjects managed for a submandibular gland cancer (SGC) between January 1997 and June 2014 were retrospectively reviewed. Survival outcomes were analyzed. All subjects had a minimum follow up of 5 years or until death. Results Of 24 subjects (13 male, 11 female), 16 (64.6%) were adenoid cystic carcinoma (ACC). Eight patients had clinically positive neck nodes and 2 of the 16 clinically negative necks were also positive histologically. None of the subjects had distant metastases at presentation. The Kaplan-Meier 5-year estimated locoregional control (LRC), distant metastasis free survival (DMFS), disease free survival (DFS) and overall survival (OS) were 62.5%, 83.3%, 58.3% and 66.7%, respectively. American Joint Committee on Cancer (AJCC) overall stage and extra glandular extension (EGE) proved to be significant predictors of LRC. Only smoking was found to be a significant factor related with lower DMFS and only EGE significantly lowered DFS. Positive nodal stage and positive surgical margin were proved to be significant predictors of OS. Conclusion Surgery alone is effective in subjects with early stage, noninvasive and low-grade cancers. Despite aggressive treatment, locoregional recurrence was common in subjects who were at advanced stage.
