Primary surgery for oropharyngeal cancer.
OBJECTIVE
The development of new techniques for transoral resection has led to a renewed interest in primary surgical treatment of oropharyngeal squamous cell cancer (SCCA). We reviewed our experience with primary surgery for oropharyngeal SCCA to identify factors associated with survival.


METHODS
Case series with chart review.


METHODS
Tertiary medical center.


METHODS
Patients who underwent primary surgical treatment of oropharyngeal SCCA from 1985 to 2002 were analyzed. Patients who failed nonoperative treatment or had distant metastases at presentation were excluded.


RESULTS
A total of 105 patients met study criteria. The majority of patients (91%) had advanced stage disease (III/IV). All patients received postoperative radiation; chemotherapy was used in eight patients. Five-year disease-free survival was 83 percent for stage I, 67 percent for stage II, 56 percent for stage III, and 43 percent for stage IV disease. Crude local control rates were 94 percent for T1 disease, 90 percent for T2 disease, 81 percent for T3 disease, and 80 percent for T4 disease; crude regional control rates were 100 percent for N0 disease, 90 percent for N1 disease, 84 percent for N2 disease, and 82 percent for N3 disease. Cox proportional hazards models revealed that nodal stage (hazard ratio [HR] 2.3, P = 0.02) and black race (HR 2.6, P = 0.004) were the only significant predictors of disease-free survival.


CONCLUSIONS
Primary surgical treatment of oropharyngeal SCCA is effective in achieving excellent locoregional control and permits deintensification of adjuvant therapy, even in patients with advanced stage disease. Nodal status and race are the primary determinants of disease-free survival. These data provide useful information for counseling and treatment planning.
