Abstract
OBJECTIVES
Treatment outcome of patients with oral and oropharyngeal squamous cell carcinoma (OOSCC) achieving complete pathologic response at the primary site (ypT0) but incomplete response in loco-regional lymph nodes after preoperative chemoradiation (ypN+) is poorly described in the literature. This study's objective was to assess the survival of patients with OOSCC with ypT0N+ disease.
STUDY DESIGN
176 patients with primary locally advanced OOSCC undergoing preoperative chemoradiotherapy were stratified according to the pathologic TNM classification into 6 groups: ypT0N0M0 (46%), ypT0N+M0 (10%), ypTNM I (24%), ypTNM II (4%), ypTNM III (6%), and ypTNM IV (10%).
RESULTS
Three-year overall survival (OS) and recurrence-free survival (RFS) rates for the ypT0N+M0 group were both 61.8% and were similar to those of the ypTNM I group (OS 62.4%; RFS rate of 59.2%).
CONCLUSIONS
Survival analyses showed that patients with OOSCC with ypT0N+ disease have a similar prognosis to those with pathologic TNM stage I.
