Background
This study examined surgical trends for oropharynx squamous cell carcinoma (OPC) from 1998 to 2012, with a post-2009 focus coinciding with the Food and Drug Administration (FDA) approval of transoral robotic surgery (TORS).
Methods
Using the National Cancer Data Base, the study analyzed 84,449 patients with stage I-IVB OPC. χ
2 tests and logistic regression models were used to examine surgical trends.
Results
The use of surgery decreased from 41.4 % in 1998 to 30.4 % in 2009 (p < 0.001). The surgical trends reversed and in 2012 increased to 34.8 % (p < 0.001). There was much variation in surgery in 2012 between American Joint Committee on Cancer stages, with 80.2 % of stage I patients receiving surgery compared with 54.0 % of stage II patients, 36.8 % of stage III patients, and 28.5 % of stage IV patients (p < 0.001). Black patients with high socioeconomic status (SES) showed lower use of surgery (25.3 %) compared to low SES white (32.3 %) and low SES Hispanic patients (27.3 %) (p < 0.001). The highest surgical rates were noted in the West North Central region and lowest rates were observed in the New England and South Atlantic regions. Between 2009 and 2012, independent predictors of surgical treatment included young age, female gender, white or Hispanic race, high SES, private insurance, academic hospitals, hospitals in the West North Central region, residence more than 75 miles from the hospital, increasing comorbidities, stage I disease, and tonsil origin (all p < 0.05).
Conclusion
Since FDA approval of TORS in 2009, surgical rates have increased with multiple socioeconomic and regional factors affecting patient selection. This study provides a basis for further investigation into factors involved in decision making for OPC patients.
