Few studies have been conducted investigating clinical presentation, staging, prevalence of cervical metastases, and outcomes in this population. The primary objective of this study was to analyze predictors of disease\u2010free survival (DFS) in surgically treated patients, particularly as it relates to the role of neck dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design<\/jats:title>\n                    <jats:p>Cohort study with planned data collection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cohort study used planned data collection over 15 years (1994\u20132008) at a large tertiary care cancer center to study all patients presenting with squamous cell carcinoma of the maxillary alveolus and hard palate treated surgically. Univariate and multivariate Cox regression analyses were used to identify predictors of DFS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ninety\u2010seven patients met the inclusion criteria (54 male, 56%). The majority of patients (54, 56%) presented with locally advanced disease (cT3, cT4). Occult nodal metastases were noted in 26% (17 of 65) of patients clinically staged as N0. The 3\u2010year DFS was 70% (95% confidence interval\u2009=\u200959%\u201378%) with a median time to failure of 1.1 years (range\u2009=\u20090.3\u20139.7 years). Cox regression multivariate model demonstrated that advanced pathologic T stage, hard palate tumor site, and poorly differentiated tumor grade were each independent predictors of DFS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A significant portion of the patients with hard palate and maxillary alveolus tumors harbor occult cervical metastases.
