.. not available for a specific reference period ... not applicable Notes: Quebec is excluded because cases diagnosed in Quebec from 2011 onward had not been submitted to the Canadian Cancer Registry. Net survival estimates were predicted using the period method. Age-standardized estimates were calculated using Canadian cancer survival standard weights, see reference 2. Age-standardized estimates for anaplastic thyroid cancer were not available because one or more age-specific estimates were undefined. The adjustment by sex applies only to all thyroid cancers combined. Sources: Statistics Canada, Canadian Cancer Registry death linked file (1992 to 2014) and life tables. |
