Incidence Rates of Thyroid Cancer for Nova Scotia
1971-2006

• Rate of incidence is increasing faster since 2000
• Changes more pronounced in females
• Rate has increased by 6x for both sexes

rates age-standardized to 1991 Canadian Census

Incidence Rates of Thyroid Cancer for Nova Scotia
1996-2006by age and sex

• Unlike males, increased risk in females is
  greatest in the reproductive years (15-45)

Incidence Rate of Thyroid Cancer by Histological
Type 1971-2006

• 4 major histological types
• Papillary showing the only increase

6
Burden of Thyroid Cancer(Survival)

• 5 yr survival is 92
• Mortality is low, particularly in papillary
• Prognosis for anaplastic type is poor

7
5 Year Survival is Increasing Over Time
8
Relative Burden of Thyroid Cancer to All Cancers
(1995-2004)

• Relative burden is low compared to all cancer
  sites combined

9
Conclusions

• The recent trend in incidence is cause for
  concern
• There are differences in incidence between the
  sexes and at different ages
• The rise in incidence is due to a non-fatal
  histological type
• Overall burden is low (2) relative to all other
  cancers

10
Recommendations

• Due to the low burden and low (although
  increasing) incidence, special programs would not
  be an effective use of funds
• Although mortality burden is low, further
  research needs to be conducted to determine
  causes of
• Recent increase in incidence rate
• Differences between sexes and ages
• New research should be collaborative with other
  areas of the country
