Kaplan-Meier survival analysis stratified by American Joint Committee on Cancer (AJCC) tumor (T) staging among cohort of subjects from the National Cancer Database (NCDB) with overall stage III and stage IV hypopharyngeal squamous cell carcinoma diagnosed between 2005 and 2015. Chemoradiation (CRT) was defined as primary radiation and chemotherapy. S + Adj was defined as primary surgery with adjuvant CRT or adjuvant radiation therapy. (A) Demonstrates overall survival (OS) among subjects with T1 disease. (B) Demonstrates OS among those with T1 disease with S+Adj stratified into surgery with adjuvant radiation therapy (S+RT) and surgery with adjuvant chemoradiation therapy (S+CRT). (C) OS among patients with T2 disease. (D) OS among patients with T2 disease, where S+Adj was stratified by S+RT vs. S+CRT. (E) OS among patients with T3 disease. (F) OS among patients with T3 disease with S+Adj stratified into S+RT and S+CRT groups. (G) OS among patients with T4 disease. (H) OS among patients with T4 disease with S+Adj stratified into S+RT and S+CRT groups.
