Session: SUN 459-496-Thyroid Neoplasia & Case Reports
Poster Board SUN-472
Methods: We used data from the Canadian Thyroid Cancer Consortium, a large thyroid cancer registry that collects data from two major thyroid cancer referral centers (London, Ontario and Halifax, Nova Scotia). We included patients who presented with thyroid cancer between 1998 and 2011. We determined age at presentation, sex, and thyroid cancer status using the AJCC staging criteria. Individual’s postal codes were used to retrieve data from the Canadian Census for the years 1996, 2001 and 2006 to approximate household income. Logistic regression was used to determine odds ratios of presenting with advanced stage thyroid cancer as they relate to income, age, and sex.
Results: We included 1701 patients, 1334 cases from London and 367 from Halifax. Thyroid cancer was diagnosed more frequently in the higher SES groups (p<0.001). Compared to patients in the top income quintile, patients in the lowest and second lowest income quintiles had significantly higher odds of having more advanced stage thyroid cancer at presentation (OR 1.58, p=0.002; 1.37, p=0.024 respectively). Older age was associated with more advanced thyroid cancer (OR 1.02, p<0.001). Men were more likely than women to face higher stage thyroid cancer (OR 2.10, p<0.001).
Conclusion: While thyroid cancers were diagnosed more frequently in patients of higher SES, patients in the lower SES groups had more advanced stage thyroid cancer at presentation. Our study indicates that health disparity exists in thyroid cancer in Canada.
