Overview of surgery for laryngeal and hypopharyngeal cancer in Ontario, 2003-2010

Background — The primary purpose of this study was to describe variations in incidence rates, resections rates, and types of surgical resection for patients diagnosed with laryngeal and hypopharyngeal cancers in Ontario.

Methods — All laryngeal and hypopharyngeal cancer cases in Ontario (2003-2010) were identified from the Ontario Cancer Registry (n = 3034). Variations in incidence rates, resection rates, and type of surgical resection were compared by sex, age group, neighborhood income, community population, health region, and physician specialty.

Results — Incidence rates per 100 000 vary significantly by sex, age, neighborhood income, and community size. Women, the elderly (75+ years), those in the higher income quintiles, and those living in larger communities were significantly less likely to receive a laryngectomy procedure.

Conclusions — Laryngeal and hypopharyngeal cancer incidence rates vary by sex, age, neighborhood income, community size, and health region. Resection rates vary by age, sex, and health region. These disparities warrant further evaluation to improve the quality of delivered care in Ontario.
