title: [Thyroid cancer in Southeastern Netherlands, 1970-1989: trends in incidence, treatment and survival].
abstract: OBJECTIVE
  To describe the (changes in) incidence, treatment and prognosis of thyroid cancer (TC) in the period 1970-89 in the South-east of the Netherlands.
  
  
  METHODS
  Eindhoven Cancer Registry, Comprehensive Cancer Centre South (I.K.Z.), Eindhoven.
  
  
  METHODS
  Retrospective.
  
  
  METHODS
  Data were collected from al TC patients (ICD-O code 193 and non-Hodgkin lymphoma originating from the thyroid) diagnosed in the period 01.01.1970-31.12.1989. Histological, treatment and survival (on 01.07.1991) data were collected. The standardised incidence, prevalence, (relative) survival and mortality were calculated for men and women.
  
  
  RESULTS
  The mean age of the 297 TC patients was 52 years; the male-female ratio was 1:2.3. 46% Of the TC patients had papillary TC, 35% follicular TC. The incidence of TC increased from 1.4 to 3.0/100,000/yr for females, the incidence remained unchanged for males (1,1/100,000/yr). The point prevalence (01.07.1991) was 25.6/100,000 for females and 8.2/100.000 for males. TC patients were treated in all hospitals in the region and were increasingly first seen bij an internist. There was a trend to more extensive surgical treatment and iodine-131 treatment in differentiated TC. For all TC patients the crude 10-year survival rate was 61%, the relative 10-year survival rate was 74%. Survival was related with sex, age and histological type. Mortality from TC remained very low.
  
  
  CONCLUSIONS
  The incidence and prognosis of TC were similar to the surrounding countries. In general the recommendations from the consensus meetings for treatment of TC in 1985 and 1987 appear to be followed.
