A contemporary analysis of racial disparities in recommended and received treatment for head and neck cancer.

ABSTRACT

BACKGROUND: Racial disparities in squamous cell carcinoma of the head and neck (HNSCC) negatively affect non-Hispanic black (NHB) patients. This study was aimed at understanding how treatment is prescribed and received across all HNSCC subsites. METHODS: With the National Cancer Database, patients from 2004 to 2014 with surgically resectable HNSCCs, including tumors of the oral cavity (OC), oropharynx (OP), hypopharynx (HP), and larynx (LX), were studied. The treatment received was either upfront surgery or nonsurgical treatment. Treatment patterns were compared according to race and subsite, and how these differences changed over time was evaluated. RESULTS: NHB patients were less likely than non-Hispanic white (NHW) patients to receive surgery across all subsites (relative risk [RR] for OC, 0.87; RR for OP, 0.75; RR for HP, 0.73; RR for LX, 0.87; all P values <.05). They were also more likely to refuse a recommended surgery (RR for OC, 1.50; RR for OP, 1.23; RR for HP, 1.23; RR for LX, 1.34), and this difference was significant except for HP. NHB patients were more likely to not be offered surgery across all subsites (RR for OC, 1.38; RR for OP, 1.07; RR for HP, 1.05; RR for LX, 1.03; all P values <.05). Rates of surgery increased and rates of not being offered surgery declined for both NHB and NHW patients from 2004 to 2014, but the absolute disparities persisted in 2014. CONCLUSIONS: Across all HNSCC subsites, NHB patients were less likely than NHW patients to be recommended for and receive surgery and were more likely to refuse surgery. These differences have closed over time but persist. Enhanced shared decision making may improve these disparities.
